The app's story 🛠️
The original app was created by Slovak developer Tibor Kaputa (Simple Mobile Tools). Unfortunately, he sold it, and the new Israeli company immediately introduced an overpriced subscription model and ads. Naturally, this led to the creation of a new branch—first the Indian fork "Fossify," and subsequently this Czech 🇨🇿 fork of mine, which gets the app back on the right track and responds quickly to your feedback 💪

I would appreciate any reviews or ideas for improvement. Just please 🙏 keep the core philosophy in mind: simplicity and functionality!
