What's your hour worth? Some days, just sitting down at your desk is the hardest part. Some days you wonder, "Will this studying ever end?" Timemoa is a study timer built for those days β€” it shows you exactly what today's focus is worth. "If becoming a doctor is worth $1,000,000, what is one hour of studying worth right now?" $1M, 2 years, 8 hours a day β€” your hour is worth $173. From the moment you start focusing, that value stacks up in your Vault. β—† The value of your hour Divide your goal's value by your investment period and daily target hours β€” that's what your hour is worth right now. Not sure what number to use? The value helper only needs your expected salary and working years. Now you have a reason to start. β—† Focus, and it adds up The moment you start the focus timer, value accumulates in real time. Watch our signature hourglass fill your hour with falling golden sand. Plain focus or Pomodoro (25 min focus Β· 5 min rest) β€” earn at your own rhythm. β—† Showcase β€” a medal for consistency Every 100 hours of focus adds a gold bar to your Showcase. Hours you've already collected count retroactively. When you can see "I've done this much," you can sit down again tomorrow. Share your gold bars as an image β€” consistency is worth showing off. β—† It's okay to rest Rest is part of studying. We show the value spent on rest, without blame. If the deduction feels heavy, switch it to half or none β€” with none, your Vault stays untouched while you rest. β—† Vault & streaks Today's earned value, Vault balance, a 7-day chart. Hit your daily goal and your streak continues. Streak Shield β€” even on a day you miss your goal, it spends one day's value to protect your streak. β—† Time adds up even without opening the app Β· Lock Screen & Control Center buttons β€” start without unlocking Β· Home & Lock Screen widgets β€” today's value and goal gauge, start/stop right from the widget Β· Live Activity & Dynamic Island β€” your growing value, always in sight Β· Apple Watch β€” check, start, and finish from your wrist Β· Hourly notifications celebrate today's progress β—† Made for Β· Students with a make-or-break exam ahead β€” college entrance, med/law school, civil service, certifications Β· Professionals preparing a career change after work Β· Anyone who needs "how much did I earn today?" more than "how long did I study?" Β· People for whom starting is the hardest part β—† Your records are yours All data stays on your device and in your own iCloud. Β· iCloud backup β€” switch devices and restore in one tap Β· No login, no ads, no data collection β€» All amounts shown in the app are virtual motivational values that translate your goal into the value of your time.
