Summon

Your next meeting shouldn't have to beg for your attention. Summon rings a full-screen alarm right before your meeting starts — through Silent mode, through Focus — with the join link already detected and one button to get in. Free to download. No nags, no timers, no locked alerts. AN ALARM, NOT A NOTIFICATION Banner notifications are built to be ignorable. Summon isn't. It schedules a real system alarm for your meeting, so it takes over the screen, rings at alarm volume even when your phone is silenced or a Focus is on, and counts down in the Dynamic Island. It stays up until you join or dismiss it. ONE TAP AND YOU ARE IN Zoom, Google Meet, Microsoft Teams, Webex, FaceTime, WhatsApp and many more links are detected automatically from your event's URL, location and notes. The alarm carries a Join button: tap it and the meeting opens. No hunting through the invite for the link while everyone waits. THREE DAYS AT A GLANCE The agenda shows today, tomorrow and the day after, with what is up next raised to the top. Tap any meeting for its notes, the dial-in code, the join link and whether an alarm is armed. Meetings with no join link can be hidden entirely. ALARMS THAT RESPECT THE REST OF YOUR LIFE - Ring 1, 2 or 5 minutes before the meeting starts - Five tones to choose from, plus No Sound for a silent full-screen takeover - Quiet Hours: a nightly window where alarms stay silent - Pause alarms for a while and they resume automatically — anything ringing after the pause still rings - Cancel a meeting in Calendar and Summon cancels its alarm, even in the background YOUR CALENDAR NEVER LEAVES YOUR DEVICE Summon reads your calendar through Apple EventKit entirely on-device, and schedules every alarm locally. Zero outbound network connections. Your schedule, your meetings, your attendees: none of it is transmitted. This is a verifiable promise, not a privacy policy paragraph. SUMMON PRO: MONTHLY, YEARLY OR LIFETIME Unlimited alarms (vs 10 for FREE) on iPhone, iPad and Mac. Three ways to have it, and all three unlock exactly the same thing: - Monthly: auto-renewing, with a 7-day free trial for new subscribers - Yearly: auto-renewing, with a 7-day free trial for new subscribers - Lifetime: one payment, yours for good Bought Summon PRO before? It is Lifetime and stays unlocked forever. Restore Purchases brings it back on any device. Late to calls because your phone was face-down or on silent? This is the alarm that gets through. Running back to back and losing the two minutes before every call hunting for the link? One tap, every time. Experience time blindness or hyperfocus where standard notifications disappear entirely? A full-screen alarm is the intervention that works. iPhone and iPad. iOS 26 or later required. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple Account when you confirm, or when the free trial ends. Manage or cancel any time in your Apple Account's subscription settings. Lifetime is a single payment and does not renew.

Verdict
The clearest difference is update cadence: Flip Clock at every 3 days against Summon's monthly. Flip Clock also leads on iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
