Genius Scan 3.7 for iOS with Multi-Selection

Genius Scan is regarded as the fastest way to scan, organize and export your documents wherever you are.

Over the past few weeks we've been busy building two new features: the first one is the multi-selection which lets you apply actions to several documents or pages at the same time. Next is what we named "Smart document names" which allows you to name the documents the way you want. Last but not least, exporting a business card to Microsoft OneNote will now extract the contact information.


The multi-selection renders possible:
These features won't get in your way if you are not using them, though activating the multi-selection is particularly easy: tap Edit in the top right corner of the screen and the toolbar will update with all the multi-selection options.

We know that this feature will save you a lot of time!

Smart Document Names

In previous version of Genius Scan, documents have always been named using the current date (2015-02-21 19:55). This pattern is very convenient because it lets you sort your documents by date. However, different users have different needs and that's why we are introducing the smart document names.

You can now define rich patterns for your document names. You build a document name by adding different items to the pattern. Dates, times, custom text and even your current location can be used to name documents.

Documents can be named using the date,
time or even the current location.
Smart document names can be turned on in the settings. They are available in Genius Scan+.

Smart document names are available in the settings

Auto-Extraction of Business Cards with OneNote

Last but not least, we have a cool bonus feature. If you are exporting business cards to Microsoft OneNote, the different fields (name, address, phone, email …) will be extracted and a contact will be attached to your note.

Let us know what you think on Twitter @thegrizzlylabs.

Box Goes Public on the New York Stock Exchange - Congrats!

Today, Box went public on the New York Stock Exchange. We first wanted to say congrats to everyone at Box. As part of the OneCloud group, Genius Scan has been a small part of this journey and even got a mention in Box S-1 filing with the Security and Exchange Commission. We are proud to have been one of their early partners.

Genius Scan's integration with Box is one of our favorites. It enables small businesses to scan and store paper documents directly in their Box account. Once there, they can be archived for later use or shared within the company with precise privacy controls.

Having a scanner at hand, particularly when in the field, is not very common. Being able to quickly scan documents into Box can be useful in a lot of scenarios:
  • Collecting student forms at the beginning of a program
  • Small aircraft companies documenting pilot certificates, medicals or any expenses such as fuel. Relying on airport copiers to do so can be time consuming but scanning with Genius Scan and sending to Box is quick.
  • Insurance agents sending customers forms filled out and signed directly to the headquarters
  • Nurses quickly sending prescriptions and documents between hospital departments
  • Teachers digitizing students homeworks and storing them in the cloud for later grading
  • Construction workers and architect snapping pictures of maps and blueprints for later reference

Concretely, scanning to Box is just a few easy steps:
Scan a paper document

Save the pages in a PDF file if needed

Rename and chose the folder as needed

Export in the background, get notified when it's successful

Your file is on Box, you can share it, comment on it etc.

Box integration is available in Genius Scan+ for iOS and Android.

What's new in Genius Fax 2.0.3

The first update of the year is for Genius Fax. Genius Fax is Genius Scan's little brother allowing you to fax documents from anywhere. Version 2.0.3 is an incremental update to improve upon the existing version. Here is what's new:

iPhone 6 support Genius Fax takes full benefit of the larger screens on iPhone 6 and iPhone 6 Plus.

Improved cloud support Cloud support is extended on iOS 8 to support more services as well as iCloud Drive. You can now chose PDF and images to fax from any compatible cloud app (Box, Dropbox, Google Drive, OneDrive, ...)

Enhanced compatibility with Genius Scan. If your document has already a title in Genius Scan, Genius Fax will re-use that title for the fax.

Support for more countries. Belgium, Greece, Netherlands, Romania, Saudi Arabia, Spain, Sweden, Switzerland are now available. We will keep adding more over the next few months.

As usual, we are always available at for any questions or feedback!

Implementing a Large Scale Document Storage Service

In this post, we explain why we decided to work on a document storage service for Genius Scan and how we are approaching this engineering challenge. We think that the process is worthy of being shared and we also hope to get feedback from the community.

A little background

At The Grizzly Labs, we create helpful productivity apps. Our main product, Genius Scan, is a scanner for iOS and Android. It’s one of the most popular mobile apps, netting more than 15 million downloads since its debut in June 2010 — we never invested a cent in advertising — and constantly receiving great feedback.

Genius Scan is at the interface between the physical and the digital world: it enables you to snap a photo of a paper document, to correct any perspective distortion and to process it like a real scanner. With several scans, you can build multi-page PDF documents. Genius Scan is also particularly good at exporting them wherever you want (Box, Dropbox, Email, Evernote, Expensify, Google Drive, OneNote, OneDrive, FTP, WebDAV…)

While we expected users to use Genius Scan to scan and export documents, we noticed that a lot of them are using Genius Scan to store their scans for the long term.

Solving problems for our users

Genius Scan stores documents on the phone in the local app folder. Due to the app sandboxing, this folder is only accessible to Genius Scan and documents are not synced between different devices. They also never leave the phone unless you decide to export them (the exception being your automatic iOS backups). This has two advantages: simplicity of implementation and privacy.

Yet, after 4 years of answering support emails, we are clearly seeing patterns in user requests:
  • Backup. Users can lose documents for many reasons: accidental deletions, improper install of new OS updates, phone lost or stolen. The unsatisfying workaround is to restore a complete phone backup from iCloud, provided that users have any.
  • Device migration (transfer of documents from an older device to a newer one). The problem arises during cross-platform transfers, typically between iOS and Android. There is no obvious way for users to access the documents they created on the previous platform. The workaround is to export the documents to a cloud service such as Dropbox. Users can later access them within the Dropbox app on the new device. We experimented with a backup and restore system for the Android app, but it’s more a patch than a satisfactory solution. This issue can arise as well when upgrading iOS devices if the user doesn’t have device backups setup.
  • Synchronization (accessing documents from any device). Users scan documents on their phones and want to read them afterwards on a tablet. The only way to do this currently is to export the documents to a service such as Dropbox and view them on the tablet within the Dropbox app. Likewise, users would want the documents to magically appear on their computer.
  • Extra features which require processing power or a backend. Examples of such features are: OCR, OCR indexing (similar to what Evernote does), document signing and sharing.
All this feedback keeps showing us the need for a document storage backend with synchronization logic.

Self-imposed requirements

One of the main challenges we face is that Genius Scan is already at large scale. Our millions of monthly active users scan about 250,000 new documents every day and have already generated more than 200 million scans. While we can find ways to stagger the launch, we can’t build a simple architecture that we would subsequently scale.

Looks like Mondays are scanning days, and that nobody scans turkeys :)

Our backend needs to meet the following requirements:
  • Security and privacy. Obviously, the first feature of this backend.
  • Data integrity. Users store very important documents in Genius Scan (losing receipts can translate into thousands of dollars that cannot be expensed.) There cannot be any loss of document as a consequence of users turning on synchronization.
  • Ability to handle network conditions. Mobile devices can go offline for a long time, and then pop back online (eg.: a user scans documents during a flight)
  • Cross-platform. We need to support iOS, Android and potentially other platforms.
  • Optionality. Users don’t have to use the synchronization, particularly if they have privacy concerns.
  • Financial sustainability. we plan to be able to cover the costs associated with this backend for the long run. A simple spreadsheet and a few estimations are enough to understand the cost structure. In our case, the monthly storage cost (S3) will dominate.

Different options

Synchronization is a typical problem and there are various alternatives:
  • With iCloud, iCloud Drive, no server-side work would be required. However, backup, device migration are not addressed, and synchronization only partially. One of our worries with iCloud was its instability, but it overcame this bad reputation with iOS 7 and 8.
  • CloudKit is also a potential solution. Given our scale, though, it won’t be a good fit due to the storage limits. On top of that, it’s limited to iOS.
  • Cross-platform cloud storage services: Dropbox, Box, OneDrive… Using these services as a backend tackles backup, device migration and synchronization and we wouldn’t be reinventing the wheel. There are several drawbacks: we need to adapt to their synchronization model — with Dropbox: the sync unit is the file — and we also become dependent on a third-party platform. Last but not least, any extra features (indexing, search, OCR) will be harder to offer since we won’t manage the document storage.
  • Ensembles developed by Drew McComack is an impressive project and could be an appropriate solution. However, it only synchronizes objects stored in Core Data: it wouldn’t be trivial to synchronize the scans themselves. It also doesn’t support Android (that being said, Ensembles 1.x is an open source project and could be extended.) Last, the cloud is used for temporary transfer, and not for data storage (peer-to-peer synchronization model) so it wouldn’t be usable for backup and extra features.
  • Our own service. This would address the different feature requests although the main drawback is that we would be reinventing the wheel.
After meeting with several top enterprise companies in San Francisco and in France, we decided to settle on implementing our own service due to the drawbacks of other solutions.

Steps we’ve taken

It’s crucial for us to identify trouble early. However, it’s easy to keep listing potential issues and corner cases and postpone the implementation, so we decided to take iterative steps towards our goal.


We are estimating the load that our millions of MAU would generate on our backend through a couple channels: metrics and surveys. They are a lot of options for metrics. As for surveys, we can query users by displaying an in-house banner ad in Genius Scan. We also ask people who contact us for support.

An important metric is how many documents a typical user (vs. a power user) has. We are also interested in estimating the peak rate of document scanning during a day.

On top of that, surveying users enables us to understand the financial sustainability: Are users ready to pay for such a service? Should we offer a limited trial to everyone? etc.

Using the Dropbox SDK in our Android app

To get started, we wanted to put together a version of Genius Scan with some kind of synchronization. We first implemented a simple prototype by modifying the Android version of Genius Scan to use the Dropbox Sync API. This was fairly quick and took a couple day for a rough implementation.

Having such a prototype had several benefits: first, it gave us some self-confidence regarding the feasibility of this project. Second, it let us play with something concrete in order to think about the UX of the client apps; and finally, this was a first step in identifying potential issues on Android and in general (what are the typical synchronization conflicts, what behavior would we expect as users).

Custom implementation

Our next step was to develop our own client-server solution. This time, we focused on the iOS app. We developed a straightforward backend using Sinatra. We covered this implementation with extensive specs in iOS and Ruby for the server.

We based our architecture on Evernote’s synchronization. The brain of the synchronization is located in the client and the server holds the state. In some ways, the model structure is similar: In Genius Scan, documents contains pages, and can be optionally tagged. In Evernote, notebooks contain notes and can be optionally tagged.

Our client implementation fits nicely with the existing Core Data code Genius Scan relies on. It’s also surprisingly not intrusive: all the synchronization happens in a different managed object context and the contexts use decoupled notifications to communicate.

The goal of this iOS prototype was to deepen our understanding of the synchronization. The first iteration of this implementation took a bit less than a week to develop without the conflict handling.

We are refining this early implementation (we plan to write a more technical blog post on the subject). Note that it still focuses a lot on the client side and that our server component is running on fast local network. One of the next moves will be to test this implementation under real network conditions including latency and errors.


The two of us are super excited to be working on this project that we had postponed for a while. We want to provide this service to our users as soon as we can; however, we are not in a hurry. Since we don’t have any pressure, we can take our time to get it right.

If you’ve read until here, we are also very interested in your feedback (Hacker News). In any case, rest assured that we will keep you updated on our progress.

Genius Scan 3.6 with iOS 8 compatibility

We keep making scanning and exporting your documents easier with Genius Scan 3.6.

Specifically, for iOS 8, we are excited to introduce a number of new features:

Export your documents to iCloud Drive

With iOS 8 (and soon MacOS X Yosemite), Apple introduced iCloud Drive, an easy way to save all your documents in the same place, wherever they come from. To export to iCloud Drive, just use the Export feature as usual:

Export to iCloud Drive

Import scans from iCloud Drive

It's also possible to import scans from iCloud Drive in Genius Scan to process them and use them as part of a PDF file. To import a scan from iCloud Drive, perform a long press on the Photos scan button and choose your image document:

A long press on the Photos
button triggers the import
from iCloud Drive.

Compatibility with the new iPhone 6 and iPhone 6 Plus

The new iPhone 6 and iPhone 6 Plus offer larger screens with more real-estate. By default, Apple scales app so that they use the full screen, but it looks a bit blurry. Being compatible with the iPhone 6 and iPhone 6 Plus, Genius Scan will look great on those phones. Genius Scan takes advantage of this larger screens to display more of your documents.


We think that iOS 8 is a great update, and as of iOS 8.0.2, there are no known issues that should prevent you from upgrading. But if you decided not to upgrade (or if you can't), we have a load of new features coming for everyone:

Support for choosing a location when exporting to OneNote (notebook and section)

Your OneNote account is organized in notebooks, and each notebook is subdivided in sections. With Genius Scan, you can now choose in which section of which notebook you want to export your documents.

Select the destination as you
export to OneNote.

Ability to scan from the Photos or iCloud Drive when adding a page to a document

Before this version of Genius Scan, it was easy to add a new scan to a document from the camera, but not from your photos. Now, when you tap the + button in an existing document, you will have the choice to import from the camera, your photos or iCloud Drive.

Tap on the add button at the
bottom of the document view

Select the source when
adding a page to an existing

Ability to use self-signed certificates with WebDAV.

Sometimes, when you host your own WebDAV server, you don't want Genius Scan to reject self-signed certificates. You can then turn on the self-signed certificate option (use with caution !)

The self-signed certificate option
is located in the WebDAV settings.

Updated self-help system

Also available at, our updated help system offers great tutorials and answers to all your questions. And if you can't find an answer, we're always an email away.

The new help system

And of course, we fixed a bunch of nasty bugs.

Genius Fax now available on Android

Today we take a new step to make our genius tools available to more users and small businesses. We are excited to announce that Genius Fax is now available for Android.

We originally created Genius Fax for iOS because there wasn't any good application to send faxes. It's annoying enough to have to send a fax, so why should it be painful because the applications are badly designed or have hidden costs.

Android users will now benefit from the same hassle-free features our iOS users have enjoyed for more than a year:
  • Faxing documents located in any app
  • Subscribing to a fax number to be able to receive faxes directly on your phone
Our pricing stays simple: one page costs one fax credit (for international, long distance or local #). You purchase credits for as low as 39c if purchased in bulk. The cover page generated by Genius Fax is always free.

As always, we will quickly reply to your feedback. Email us at

Below are a few screenshots of the app to show you how simple and friendly it is:

A friendly UI to start with.

Your fax history clearly
displays the status of your

Sending a fax is as easy
as entering a fax number
and a few optional details.
