On-Timer helps people with ADHD be on time for meetings with a 3-stage alarm sequence that coaches you through preparation. HOW IT WORKS On-Timer reads your calendar and lets you set three coaching alarms for any meeting: ⢠Get Ready (30 min before) ā "Time to wrap up!" ⢠Get Set (15 min before) ā "Head to your desk!" ⢠Go! (1 min before) ā "Join now ā you've got this!" All timings are configurable in Settings. TWO REMINDER LEVELS ⢠Alert (blue bell) ā Standard time-sensitive notification ⢠Alarm (red bell, iOS 26+) ā Prominent AlarmKit alarm that breaks through Focus and silent mode, so you'll always hear it VISUAL COUNTDOWN A full-screen countdown view with a kitchen-timer dial and chevron stage indicator shows exactly how long until your meeting. The chevron motif (orange ā yellow ā green) tracks your progress across the app, widgets, Dynamic Island, and Live Activity. Tap any meeting to view full event details ā attendees, notes, location ā without leaving the app. APPLE WATCH A full Apple Watch app with meeting list, countdown view, alarm toggle, and "I'm Ready" rewards. Paired iPhone and Watch sync over Bluetooth for near-instant updates, so an alarm set on one appears on the other right away. Four complication styles ā corner, circular, rectangular, and inline ā keep your next alarm visible on any watch face. ICLOUD SYNC Blue-bell Alerts sync between your iPhones and iPads via iCloud, so the alarms you set on one device follow you to the others. LIVE ACTIVITY & DYNAMIC ISLAND A persistent countdown on your Lock Screen and Dynamic Island from the first alarm stage until the meeting starts. HOME & LOCK SCREEN WIDGETS Small and medium Home Screen widgets, plus circular, rectangular, and inline Lock Screen widgets ā all with chevron progress indicators.

iWorkUntil turns the time you have left into something you can actually see ā every minute is a visible block, the grid fills as time passes, and one glance tells you where you stand in the day, the session, or the workday. Built for anyone who'd rather see time than read it. Especially good for ADHD focus sessions, deep-work blocks, study time, and any moment where "how long left?" is the question that matters. No accounts. No ads. No notifications. No streaks to break. No AI nagging. Just time, made visible. WHAT IT DOES ⢠Visual countdown ā your time as a grid of blocks that fills as it passes ⢠Pick a duration (e.g. 25 minutes) or a range (e.g. 9 to 5) ⢠Each block represents a slice of your time ā at a glance, you know where you are ⢠Choose a theme that fits your screen ⢠Lives in the corner ā never in the way WHO IT'S FOR ⢠Anyone who loses track of time when they're focused ⢠Visual thinkers who do better with shapes than with numbers ⢠Pomodoro and deep-work sessions that need a clear stop signal ⢠Workdays, homework, study breaks, screen-time wind-down ⢠Cooking, exercise, meetings, presentations ā anything time-boxed WHAT IT DOESN'T DO ⢠No notifications. No dings. No dopamine traps. ⢠No accounts, no logins, no data collection. ⢠No ads, no subscriptions, no upsells. ⢠No AI, no streaks, no guilt. A visual countdown that shows you time, instead of telling you about it. Available in 11 languages: English, German, French, Spanish, Dutch, Polish, Hungarian, Russian, Danish, Swedish, Slovenian.

Verdict
The clearest difference is update cadence: iWorkUntil at weekly against On's every 6 weeks. iWorkUntil also leads on device support. On price, in-app purchases and iOS requirement there is nothing between them.
