What is A/B Testing?

A/B Testing, also known as split testing, is an experiment to find best performing variant among 2 or more.

Users are randomly directed to different variants and their statistical analysis are measured in order to detect best performing variant for a given goal.

Subject of experiment can be user experience, user interface or content. Color of a button (UI), design of a page layout (UX) or the text on a invitation e-mail (Content) are simple examples.

A/B Testing helps companies or individuals make much better product decisions that are proven with data. This does not only increase conversion but also allows them to understand their users better and have  better opinions on their product.

AppTunnel is focused on code based mobile A/B tests and can help you with all kinds of experiments you want to perform on your mobile applications.

Why you need A/B Testing

You may think you know what is the best for user experience and conversion on your mobile applications. The thing is, you are probably wrong.

You may think, a new shiny register form with less fields will definitely increase your conversion rate. That may not be the case always.

The only way to be sure is proving it with data. A/B Tests a.k.a split tests are crucial for reaching the best versions of your mobile applications. You need to test, fix and iterate.

A/B Testing is looking to your product from user’s perspective, A/B Testing is letting your users talk about your product without actually talking. Their feedback is the magic that will do the fine tuning on your product.

AppTunnel gives you the perfect platform for creating a/b tests on your mobile applications, use it wisely and always be testing.

Why you need to use Feature Flags

Feature Flags on AppTunnel is a great tool to make mobile app releases much safer and reliable.

Mobile Apps, by their nature are hard to maintain, since they are distributed via single channel and releasing updates are hard, it is crucial for mobile app developers to have some backup solutions.

Feature Flags on AppTunnel is a great companion for developing and releasing mobile applications.

Lower the risk of releasing new features

You can use Feature Flags on AppTunnel for lowering the risk of releasing new features. Simply set-up 2 variation Feature Flag and configure this on your mobile application process. 

With AppTunnel’s control panel you can manage what percentages of user’s can access to new features on your mobile applications. 

Switching between feature variations

Use AppTunnel’s Feature Flags for switching between features. Create variations as many as the number of features you have and you can simply divert the users to features you need. 

Let’s explain that with a simple example. On iOS applications, users have 3 options for browsing. Internal browser, Safari View Controller and Safari Application. You can create 3 variation Feature Flag on AppTunnel and divert users to any option you need, to open the links on your application, without making a release, by using our control panel.

Remove unused features cleanly

On mobile applications, once a user installs your application, only users can decide about updating the application to a newer version or deleting the application.

If you need to kill a feature for all your users, not just for the updating ones, you need a solution for that. Feature Flags can help you with that. You can create a Feature Flag and you can turn off and on a feature for all your users, when you need.

Maintenance mode

Diverting users to maintenance mode screens are one of the great usages of Feature Flags on AppTunnel. You can safely block users to get access to to features and show them a maintenance mode message.

Simply create 2 variation Feature Flag for it on AppTunnel and when you are on maintenance mode, turn of maintenance variation to 100%.

Load balancing

You can use Feature Flags for load balancing by creating variations and diverting users between those variations.

You can tell some percentages of users to come back later because you are having heavy times, or you can switch users between your server variations.

Use cases of Feature Flags are infinite. AppTunnel offers a complete Feature Flag solutions for mobile application developers.

Why do we build AppTunnel, mobile a/b testing and feature flags platform

There are number of platforms doing the same job we do, mobile a/b testing and feature flagging, so why do we build AppTunnel?

The reason we are building AppTunnel is we are looking for simplicity. Most of the platforms on the market are over complicated either with their side features or with their architecture.

On our developer and product manager jobs we used different tools for mobile a/b testing and feature flagging. Best one that worked for us was from Amazon but unfortunately Amazon decided to kill that feature.

After Amazon it was a total chaos for us, we tried many tools to replace it but none of them made us happy. The reasons were mainly about inefficiency of the products or the main focus of these products was not mobile a/b testing and feature flagging.

Later we decided to go more over this problem and started building our own platform. We believe with our experience we can build a much better product and help many others to build better mobile applications.

We quitted our jobs and started working full-time on AppTunnel and after few months of hard work we are proud to release the first version of AppTunnel.

In a short time we built our platform and mobile sdks and also started using them with comfort on our some products and we love it. We believe you will also love it.

Our plan for the future is to extend our platform for the needs of our customers but we promise to keep everything simple and efficient.
