Studiary times your studying, keeps it per subject, and counts down to the exam. That is the whole app. It was built for a student who wanted something simpler than everything else on the shelf, and it is deliberately small. No streaks to protect, no leaderboard, no character to feed. Just an honest record of where your hours went. A TIMER THAT SURVIVES YOUR POCKET Studiary records when you started and works the rest out from the clock. Lock your phone, switch apps, or close it entirely - not a second is lost. SUBJECTS, AND TOPICS INSIDE THEM Track Organic Chemistry, then break it down into stereochemistry, mechanisms and spectroscopy. Topics are free on every plan. EXAM COUNTDOWNS Set the date once and every screen tells you how long is left. Optional reminders arrive a week out, three days out, and the morning of. FORGOT TO HIT START? Add the time by hand. It counts exactly the same, because an app you cannot correct is one you stop trusting. HONEST NUMBERS Today, this week, all time. Which subject is eating your evenings, how long your average session really is, and the hours of the day you actually get work done. NOTHING LEAVES YOUR PHONE No account. No sign-up. No servers. Studiary has no way to see your study data, because it never sends it anywhere. WHAT IT COSTS Free: three subjects, unlimited topics, and history that never expires or locks. One payment: unlimited subjects, eight colour themes, ninety days of patterns, and export everything as a spreadsheet. No subscription. No ads. Not now, not later.
