It is the first app I’ve ever built, and at the risk of sounding cheesy - it still holds a special place in my heart. Even though it was never a significant moneymaker, I’ve kept it updated throughout the years. And I’m happy to say that it has attained over 95.000 downloads to date. If you enjoy using the app, please consider buying the full version. Thank you. - Lukas Petr, author of Quadratic Master
