About

ClearTime

Features
Read full description

ClearTime is a visual timer for ADHD and time blindness. A solid disc of color shrinks as the minutes pass, so you can see how much time you have left without reading a number or remembering to check. A widget that is the timer Put the timer on your Home Screen or Lock Screen. While it runs, the Dynamic Island keeps it in view and a Live Activity keeps it on the Lock Screen. On your wrist The Apple Watch app is included. Set a timer with the Digital Crown, then glance at your wrist or at the complication on your watch face. Made for iPad too On its side, the timer sits on the left with your presets and controls beside it. Upright, it sits above them. Accurate through sleep The time left is worked out from the clock, not counted, so it's still right after your phone locks. When time is up A calm sound you choose and a notification let you know, even if you've looked away. Made for ADHD • Just Five: starting is the hardest part. One tap starts five minutes, and +5 keeps you going when it ends. • Heads-up: a soft cue at five minutes and one minute left, for when the corner of your eye isn't enough. • Pause, add five minutes or finish whenever you need to. Your color or a sidekick Seven colors, each with a name: Tide, Pink, Green, Amber, Blue, Purple and Orange. Or let a sidekick ride the timer: a friendly character that sits in the middle and turns as the time runs down. Cloud and Unicorn come free. The Halloween pack (Ghost, Pumpkin, Black Cat, Witch, Frankenstein and Dracula) is a one-time purchase, yours to keep and shared with your family. ClearTime Plus A yearly subscription for more: • Routines: timers that run one after another by themselves. A list of steps like Morning or Bedtime, or work and rest that repeat like Deep Work. • Distraction notes: jot one line while you focus and get the list back at the break. • History: the timers you finished, kept on your device. • Custom colors: any color you like for the timer. • Every sidekick pack, now and to come. No account, no data collected Open it and set a time. ClearTime doesn't collect any data, and the timer works without the internet. ClearTime is a timer, not a task manager. Why I made ClearTime I have ADHD. When I had to focus on my health, that meant coming off my ADHD medication, and without it I had to pay much closer attention to time. A clock with numbers doesn't help when I forget to look at it. I wanted to see time passing without having to think about it, so I built the timer I needed. Daniel Hayes Smith Accessible VoiceOver reads the time left in words, and ClearTime follows Reduce Motion and Increase Contrast. Also on Mac, where the timer floats over your windows, and on Apple TV. About ClearTime Plus: $19.99 a year in the US, charged to your Apple Account. It renews automatically unless you turn it off at least 24 hours before the end of the year; manage or cancel it in your Apple Account settings. If Plus ends, you keep any sidekick packs you bought on their own. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://cleartimeapp.com/privacy
