Horae is a time-tracking app for people who don't stick to schedules. Most productivity apps assume you can plan your day in advance and follow that plan. If that's never quite worked for you, you're not broken — you just need a different approach. Horae works the other way around: track what you actually do, then see where your time really goes. NO SCHEDULES, NO PLANS, NO GUILT Start a timer when you start something. Stop it when you're done. Switch between activities as your day shifts. That's the whole loop. The app stays out of your way and shows you the patterns that emerge. SET GOALS THAT FIT YOUR LIFE Decide how much time you want to spend on Work, Sleep, Health, or anything else — daily, weekly, or monthly. Horae tells you how you're tracking against those goals without nagging you back into a rigid plan. EVERYTHING ON YOUR DEVICE - 100% offline. Your data lives in private storage on your iPhone. - No accounts. No sign-up. No cloud uploads. - No ads. No tracking. No analytics. - Crash reports go through Sentry with personal text stripped out. - Export everything as JSON or CSV anytime, or wipe it all in one tap. WHAT'S INSIDE - A clean timer that recalculates from the moment you started — never drifts. - A day timeline showing how your hours actually flowed. - Insights that compare your real time against your goals, daily and weekly. - Activity-level drill-downs to spot where the day disappeared. - Smart reminders for forgotten timers and long-running sessions (you control which fire and when). - Quiet hours so notifications respect your evenings. - Preset categories to start from, fully customizable to fit your life. DESIGNED FOR REAL DAYS Horae handles the messy stuff: timers spanning midnight, time zones when you travel, retroactive entries when you forgot to start, gap-filling when there's a hole in your day, and entries that bleed past their planned end. PRIVACY-FIRST, ALWAYS Your tracked time is nobody's business but yours. Future updates may add optional cloud sync for backup and multi-device — when they do, it'll be opt-in and you'll always be able to export your data and walk away. If schedules don't work for you, give Horae a try. Track honestly. See clearly. Adjust as you go.
