Most students spend hours and hours studying. Most of the time, no one sees it. Janus is the social app for academic life: post your study sessions, get appreciated for the work, and build community around what you're learning. How it works: Record a study session - add a title, what you worked on, and how long you spent. Add difficulty, location, and photos to make it your own. Your posts land in a feed for friends and classmates to see. Check class group pages to find others in your courses, and build study groups to post co-study sessions and hit group time goals together. Track your own progress over time - see your past sessions and how many hours you've put into each class this semester. Set study goals and let a little social motivation help you stick to it.

Studva is the Strava of deep work: turn your focus hours into wins you share. Whether you're cramming for an exam, pushing a side project forward or working remotely: staying focused alone is hard. Studva turns every work session into a measured, verified, social activity - just like a workout. HOW IT WORKS 1. Arrive - settle in wherever you work: library, campus, café, office. 2. Start - take a photo at the start of your session, the timer begins. It becomes half of your before/after. 3. Focus - stay locked in, the app counts distractions. 4. Share - post your before/after with your stats baked in: proof of what you got done. Friends cheer you on with a Focus and you climb the leaderboards together. VERIFIED SESSIONS Start photo, end photo, on-site presence verified by GPS. Your stats are genuine - and so is everyone else's. No fake timers in the leaderboards. YOUR TIMER, ALWAYS IN SIGHT Your time keeps running on your lock screen - and in the Dynamic Island on iPhones that have one. Pause or finish your session without even reopening the app. BLOCK WHAT DISTRACTS YOU Pick the apps to pause during your sessions: they stay out of reach until the timer ends. Studva never sees which ones you chose - the selection stays on your phone. YOUR PRODUCTIVITY COACH Every week, Studva analyzes your sessions and tells you when and where you perform best: your peak time slot, your home base, your trends. Everything is computed on your phone.
