In app purchase

Since 2017 the app has been open-source, free and without ads

Why

Nowadays app development is more difficult: Google is pushing its updates more frequently and is closing many aspects of Android, so there is a huge work for developers to keep the app compatible with latest Android versions.

Revenues from in app purchases and ads are used to:

• Developing new features
• Testing on any Android configuration (screen size, format factor, OS version...)
• Improving translations

I am not a fan of in-app purchases but it is really useful to keep the right app quality level.

What

I offer a single in app purchase to unlock some features and remove ads (called PRO version)

I think it's important to make a fully functional app to free users, without screwing features for them.

At the same time, I don't want to offer only a "Remove ads" in app purchase for PRO users.

So PRO version will always include some extra and non-strictly-necessary features

How much

The price will always be fair: around 1 Euro. Actually it is 0.99 Euros, if in the future there will be many features to the PRO version a slightly increase to 1.29 Euros would be possible
