On-Timer helps people with ADHD be on time for meetings, with a three-stage reminder sequence that coaches you through getting ready.
HOW IT WORKS
On-Timer reads your calendar and lets you set three reminders for any meeting:
• Get Ready (30 min before): start wrapping up what you're doing
• Get Set (15 min before): head to your desk and gather what you need
• Go (1 min before): join now
Each reminder names the meeting and tells you how long you have. All timings are configurable in Settings.
AUTOMATIC ALERTS BY CALENDAR
Choose your calendars once in Settings, and every upcoming meeting in them gets a blue Alert without a tap. Your choices always win: a meeting you switch off stays off, and a meeting you change keeps your change.
TWO REMINDER LEVELS
• Alert (blue bell): a standard time-sensitive notification
• Alarm (red bell, iOS 26+): a prominent AlarmKit alarm that breaks through Focus and silent mode, so you'll always hear it
RELIABLE BY DESIGN
• Each occurrence of a repeating meeting gets its own reminders
• Stopping or dismissing a reminder silences it on iPhone and Apple Watch together, and the later reminders still come; to switch a meeting off, tap its bell
• iPhone, Apple Watch and the live view stay in step, even when the app is closed
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, yellow, green) tracks your progress across the app, widgets, Dynamic Island and live view. Tap any meeting to view full event details (attendees, notes, location) 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 (corner, circular, rectangular and inline) 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. Red Alarms stay on the iPhone where you set them, and are shared with its paired Apple Watch.
LIVE ACTIVITY & DYNAMIC ISLAND
For meetings with a red Alarm, a countdown on your Lock Screen, in the Dynamic Island and on Apple Watch from Get Ready until the meeting starts, even with the app closed. It names the next stage as it goes. You can keep it up for a few minutes after the start in Settings.
HOME & LOCK SCREEN WIDGETS
Small and medium Home Screen widgets, plus circular, rectangular and inline Lock Screen widgets, all with chevron progress indicators.
AI MEETING PREP
On-device Apple Intelligence suggestions help you prepare for each meeting based on its title, timing, attendees and notes. Requires an Apple Intelligence-capable device on iOS 26+.
"I'M READY" REWARDS
Tap the button during Get Ready or Get Set to celebrate with confetti and unlock a personal micro-reward from your custom list.
