The habit tracker that uses financial accountability to make you actually follow through. Finally stick to your goals with real skin in the game. One Habit uses financial accountability to make sure you actually follow through on your commitments. Set your own accountability fee, track your progress, and only pay if you fail to do your habit. It’s the only habit tracker designed to be deleted. WHY ONE HABIT WORKS: SCIENCE BACKED METHOD TO BUILD HABITS Studies show that financial accountability is one of the most powerful motivators. Most habit trackers send notifications you can easily ignore. One Habit adds a cost to quitting. Whether it’s $1 or $10, having skin in the game is the most effective way to bridge the gap between "wanting" to build a habit and actually doing it. THE SIMPLE, AFFORDABLE ALTERNATIVE Don’t overpay for a simple feature. Other apps charge $10+ per month for AI verification and complicated "habit contracts." One Habit is built for humans who value simplicity. No AI bloat, no insane levels of verification. Just real results at a fraction of the cost. HOW IT WORKS: 1. SET YOUR HABIT: Focus on one thing at a time. Quality over quantity. 2. SET THE STAKES: Choose an accountability fee that makes you show up. 3. SET A SCHEDULE: Specify when you’ll report your progress. 4. STAY CONSISTENT: Keep your word and pay nothing. Miss a day, and the fee is charged. BEAUTIFULLY SIMPLE No streaks, no social pressure, and no cluttered dashboards. We don't want you endlessly scrolling; we want you building your habit. DESIGNED TO BE DELETED When you've successfully completed your habits, we’ll actually invite you to delete the app. We don’t have shareholders or a profit motive, so we can purely focus on doing good and getting you on your way to a better life. REAL IMPACT We are committed to doing good. One Habit donates 10% of all company proceeds to charitable organizations supporting children in need. Note on Fees: Accountability fees are service charges for the use of the platform's commitment mechanism. One Habit is a tool for self-discipline; fees are processed upon a missed check-in, admission of failure, or give-up.

Studva is the Strava of deep work: turn your focus hours into wins you share. Whether you're preparing 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 - snap your start photo, then start the timer. 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 In an approved place, GPS confirms you were there at the start and the end: your session gets the Verified badge. Place leaderboards only count verified sessions. 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 (iPhone) 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. LEVELS AND SHOP Every minute of work earns you XP. Level up and spend it in the shop: animated stickers, frames, banners and timers, right down to your lock screen. A COMMUNITY THAT PUSHES YOU - A feed of your friends: cheer with a Focus, comment, chat in private messages - Clubs: your class, your team or your friends, with built-in chat - Weekly league with friends, challenges and trophies to unlock - Streaks: stack up the days and keep your run alive OVER 500,000 PLACES ON THE MAP Libraries, campuses and study spots worldwide. Every place has its own leaderboard: become the reference of your spot. YOUR STATS, YOUR PROGRESS Time per subject or project, personal records, weekly goals, exam and deadline countdowns, CSV export. PRIVACY FIRST - Your location is only used to verify your session - never a GPS trace, never a real-time position visible to others - Your private places: only you can see where they are - Friends only by default - Data hosted in Europe, except the notification identifier (Expo, United States), never sold - Deleting your account immediately erases your profile, your sessions with their photos, and your messages Ready to make focus a sport? Download Studva and start your first session.
