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) — "Time to wrap up!" • Get Set (15 min before) — "Head to your desk!" • Go! (1 min before) — "Join now — you've got this!" All timings are configurable in Settings. TWO REMINDER LEVELS • Alert (blue bell) — Standard time-sensitive notification • Alarm (red bell, iOS 26+) — 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 → yellow → green) tracks your progress across the app, widgets, Dynamic Island, and Live Activity. 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. 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 — 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. ALSO • Volume-off detection warns you if your phone is silenced and offers to upgrade to the red Alarm tier • Past alarmed meetings shown for quick reference • Pull-to-refresh, and automatic refresh when your calendar changes REQUIREMENTS • iOS 17.6+ (core features) • watchOS 10+ (Apple Watch) • iOS 26+ on an Apple Intelligence-capable device (red Alarm tier and AI prep) • iCloud account for cross-device sync • Calendar and notification permissions

Activity Scheduler: FocusFlow is a visual activity scheduler and ADHD planner for days when a long to-do list only adds pressure. Empty your head first, then turn the noise into a day you can actually start, with a Pomodoro timer for the task in front of you. Give every task a start time and a duration. The activity scheduler lays your day out on a timeline, reminds you before each task begins and warns you before the day overflows. When it is time to work, the Pomodoro timer starts from the task you picked, so you do not have to decide again. WHAT THE ACTIVITY SCHEDULER DOES • Brain dump first, sort later: the ADHD planner keeps one clear next step • Visual time blocks instead of an endless list • Reminders before each task starts • Import Apple Reminders and calendar events • Recurring tasks for daily, weekday and weekly routines • Pomodoro timer with 25/5 sessions, a 15-minute soft start and Live Activity on the Lock Screen • Focus minutes, completed tasks, daily load and streaks • Home Screen widget and Siri shortcuts A GENTLER WAY TO KEEP GOING A small sprout grows with every focus session, and a gentle streak counts the days you showed up. At the end of the day, you decide what moves to tomorrow, without guilt. That is how an ADHD planner should feel. FocusFlow Pro adds unlimited tasks per day, AI planning that builds and replans your day, Deep Work and Study presets for the focus timer, and deeper reviews. Your plan stays on your device, with optional iCloud backup and no account. Less pressure than a to-do list, more structure than a blank page: an activity scheduler you will actually open tomorrow. Activity Scheduler: FocusFlow is a productivity tool, not a medical or diagnostic app. Privacy Policy: https://solvalex.com/en/legal/apps/privacy-policy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
