“Are you joining the meeting?” If you’ve ever gotten that message while you were sidetracked by an email, a task, or one more thing, OnTimer is for you. It’s easy to dismiss a calendar notification and lose track of time. OnTimer helps make sure that doesn’t turn into a missed meeting. OnTimer automatically keeps you on time. Connect your Google, Microsoft, or Apple Calendar once, and OnTimer does the rest—from an Early Warning before an important event to a persistent alarm when it’s time to act, and a Time to Leave alert when it’s time to head out. HOW IT WORKS OnTimer uses your existing calendar as the source of truth. When your schedule changes, your alarms automatically stay in sync—so you never have to create or maintain manual alarms. Unlike regular calendar notifications that disappear after a swipe, OnTimer uses persistent alarms that keep reminding you until you dismiss them, helping bridge the gap between noticing a reminder and actually showing up on time. High Alert helps important alarms reach you. On iOS 26.1 and later, it can ring through Silent mode and Focus/Do Not Disturb. Prefer quieter alerts? Choose Medium Alert to have OnTimer respect Focus. Want a heads-up first? Early Warning gives Pro users a lighter notification before the main alarm, so an important meeting or appointment doesn't sneak up on you. Need more time for one particular event? Adjust its main alarm and Early Warning timing without changing your defaults for everything else. USE ONTIMER FOR • Meetings and calls • Appointments • Recurring events • Work and personal calendars • Events with locations • Moments when being late costs time, trust, or causes stress APPLE CALENDAR, GOOGLE CALENDAR, AND MICROSOFT CALENDAR • OnTimer supports Apple Calendar, along with Google Calendar and Microsoft Calendar. • Connect one calendar for free, or upgrade to connect multiple calendars across work and personal life. TIME TO LEAVE ALERTS For events with locations, OnTimer helps you know exactly when to leave. Choose your preferred travel mode, add a departure buffer, and let OnTimer monitor traffic so you head out at the right time. • No more guessing when to leave. • No more scrambling when traffic is worse than expected. • Just reliable alerts that help you arrive on time. ESPECIALLY HELPFUL IF YOU • See calendar reminders and still leave late • Miss meetings even when alerts are turned on • Get focused and lose the final few minutes before a call • Want a heads-up before it’s time to stop what you’re doing and join a meeting • Need alarms that keep reminding you until you take action • Use more than one calendar • Need help knowing when to join, leave, or switch tasks • Experience time blindness or notification overload FREE VERSION • Connect one Google, Microsoft, or Apple Calendar • Automatic alarms for every calendar event • Persistent, customizable alarms • High Alert and Medium Alert options • Recurring event controls • Focus & Silent Mode settings • See which events support Time to Leave alerts PAID VERSION • Connect multiple Google, Microsoft, and Apple Calendars • Combine work and personal calendars • Early Warning alerts before your main alarm • Customize alarm timing for individual events • Business Hours • Time to Leave alerts • Custom travel modes • Departure buffer settings • 7-day free trial on the annual plan OnTimer works quietly in the background, automatically keeping you on time so you never have to think about setting alarms again.

Verdict
The clearest difference is in-app purchases: Stratum 9 at none against OnTimer's 2. Stratum 9 also leads on rating (5.0 vs 4.6) and iOS requirement (13.4 vs 18.0). OnTimer's advantage is update cadence (every 6 days vs every 5 weeks) and ratings volume (20 vs 2). On price, ads and device support there is nothing between them.
