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.

**OverRun Timer** is a precision timing app for anyone who must deliver on a fixed duration. Set a target, start your session, and track not only remaining time—but also exact **overrun**, the amount of time past your target. Use it in **Countdown** mode (set a duration) or **End Time** mode (set a specific meeting or recording end time). OverRun keeps running after zero so you always know, clearly and immediately, how far over time you are. OverRun is built to support real timing needs in everyday presentations and production workflows: - Keep talks and speeches within a target length - Run and monitor recording production segments that must fit a specific window - Stay on schedule during meetings, presentations, classes, debates, and similar timed sessions - Review timing patterns over time using saved session history ## Key Features - **Two timing modes** - **Countdown**: set a duration and run backward to zero - **End Time**: set a specific stop time and count down to that moment - **Overrun tracking that matters** - Separate displays for countdown, overrun, and total elapsed - Continue tracking after zero so every second over target is visible - **Cue system for better timing control** - Countdown cues with selectable cue packs, including **Fibonacci** - Overrun cues by every 15s, every 30s, every minute, or Fibonacci - Optional haptic alerts and sounds - **Flexible session support** - Add lap markers during a session - Save sessions manually or with auto-save rules - Set session thresholds and completion requirements for auto-save - **Notes and history** - Optional session notes and per-lap notes - Default note templates - Session history list with detail, edit, and delete options - Export sessions as text or CSV - **Meeting and production friendly** - Clear Start/Pause/Reset controls - Persisted settings and state across launches - Local notifications when countdown reaches zero ## Extra - Optional one-time support purchase to remove support prompts (no subscription) Great for timed speaking, live presentations, talks, classes, debate segments, and production workflows where **“how far over target”** is just as important as hitting the mark.
