There are few occasions where I download a FOSS (Free and Open Source) Android app, and go, ‘Wow, this is a really well-made app!’ For some reason, most FOSS apps on Android are usually never comparable to their proprietary counterparts. Some or the other feature never works, or some feature always glitches out for some reason, or it needs 5 additional apps to installed for some or the other feature to work, or certain features need proprietary blobs or libraries.
