Solo-built app just passed a bigger competitor on Google Play visibility score https://preview.redd.it/cmy3haru6veh1.png?width=1510&format=png&auto=webp&s=6c9f05bd5d22a012f123e4c4f6f26d1a7c85c5e3 Sharing this because it's a small win but it's mine. I'm the solo dev behind skillably, a study app where you upload your own notes or PDFs and it turns them into quizzes and flashcards, adapting based on what you actually get wrong. No team, no funding, built around a day job.

Focus with a customizable study timer, track study hours by subject, build streaks, manage daily tasks, and stay accountable with student leaderboards.
