4 years ago Yes, you are right that it's a bit too much for this kind of app.
To answer your question, I've used the React Native framework to develop it which basically allows you to write native apps using JavaScript. The achieve this, a JavaScript interpreter is required to run my code and this interpreter is bundled with the app. Plus, there are 4 architectures (32- and 64-bit ARM, x86 and x86-64) on which Android can run, so there are 4 copies of this interpreter bundled with the app. These, plus the JavaScript code (& JavaScript libraries), plus the native code (& native libraries) and the images add up and sum around 12 MiB (around 30 MiB uncompressed).
Until v1.2.0, the app was even bigger (around 20MiB) because it used the JavaScriptCore interpreter which wasn't designed specifically with the purpose of making mobile apps with it so the guys at Facebook came with a new interpreter called Hermes which greatly reduced its size and it's also a lot faster.
You can get a detailed view on the size of the application components by running the following command on the apk:
unzip -v com.controlloid.apkThe Length column represents the size in bytes of the uncompressed file and the Size column represents the size in bytes of the compressed file.

On F-Droid it is written that the app takes 12 MiB as a package. Isn't it too much for such an app?
