Penguin: Study Tracker

hi, made an app for people who want to actually stay consistent with their studies without being blasted by annoying ads and paywalls. ​as a student preparing for some major competitive exams, i spent months coding a 100% free and ad-free android app called penguin: study tracker. i was really frustrated with other tools on the market because everything useful was locked behind a subscription, so i decided to build exactly what i needed for my own journey. ​instead of just building a basic stopwatch, i wanted to gamify the core mechanics. the app lets you manage your curriculum, tracks how many seconds you spend on each individual question, and rewards consistency with 3d premium achievement cards to keep the motivation going. ​it has been live on the play store for a while now, but i'm looking to take it to the next level globally. since this community is amazing for honest feedback, i wanted to share it here. ​i would love to get your thoughts on the core features, the gamification system, or any ui/ux improvements you can suggest. how does the concept feel to you? ​play store link: https://play.google.com/store/ap... ​thanks a lot!
