ByeBed vs Alarmy: Which is the best mission-based alarm?

Last updated: May 26, 2026

Quick answer: Alarmy is the cross-platform veteran with 50M+ downloads since 2013 — the most mature option, available on iOS and Android, with the largest review base. ByeBed is the newer iOS-native option built on iOS AlarmKit, with on-device computer vision missions and an alarm Apple itself prevents from being canceled. If you're on iOS and want maximum snooze prevention, ByeBed. If you need Android or the most battle-tested ecosystem, Alarmy.

What Alarmy does well

Alarmy has been on the market since 2013 and has accumulated 50M+ downloads worldwide. That maturity shows: the mission catalog is wide, the bug fixes are years deep, and the App Store/Play Store review volume gives you confidence the app works on a huge variety of devices.

Cross-platform support is the biggest objective advantage. If you switch between iOS and Android, or if you share an alarm system with someone on Android, Alarmy is the obvious pick — ByeBed simply doesn't exist on Android.

Alarmy also bundles sleep tracking, sleep sound libraries, and morning routines into the same app. If you want one app for the entire morning, that's a fair use case.

Where Alarmy is weaker for iOS-only users

The same things that make Alarmy mature also add friction for someone who only cares about iOS and a hard wake-up. The honest gaps:

• Ads in the free tier. Multiple ads per session in the free version. App Store and Reddit reviews consistently mention this as the #1 friction. Premium removes them.
• AlarmKit retrofitted, not native. Alarmy supports AlarmKit on iOS 26 but the app was built years before the framework existed. It still maintains its legacy notification + audio session path for iOS 14 to iOS 25 users. ByeBed is iOS 26 only and built AlarmKit-first from day one, which means the entire mission flow is designed around the AlarmKit constraint instead of bolted on top.
• Physical missions are accelerometer-based. Squat and shake count phone movement, not body movement. A vigorous wrist flick can satisfy them. No Apple Vision pose detection.
• Photo mission is pixel-matching. You take a reference photo the night before, then retake it in the morning. Works, but requires planning and the camera can be fooled by an angle. ByeBed uses on-device AI recognition with no pre-setup.
• Feature breadth. Sleep tracking, sleep sounds, and premium missions are bundled into one subscription. You pay for features you may not use.

Why ByeBed is built differently for heavy iOS sleepers

Heavy sleepers (people who routinely hit snooze 3+ times or sleep through alarms) get three things from ByeBed that Alarmy does not offer on iOS:

1. AlarmKit-first design. Both apps now use AlarmKit on iOS 26, but ByeBed was built around it from the first commit. Alarmy retrofitted it on top of a 12-year-old codebase that still has to support iOS 14 users. AlarmKit-first means the whole mission flow is designed around the constraint (no cancel button, system-level ring) instead of layered on top of legacy mechanisms.
2. No cancel button at all. AlarmKit does not expose a cancel button on the alarm UI. The only way to stop it is to complete the mission. Alarmy lets you configure the cancel button on or off in settings.
3. Apple Vision push-up detection. Push-up missions use Apple Vision body pose, all on-device. The app counts real reps from camera frames. Alarmy's physical missions are accelerometer-based and easier to satisfy without doing the exercise.

The mission engine, compared

Both apps replace snooze with a task. But not all tasks are equal at defeating sleep inertia.

Cognitive missions

ByeBed Math: typed answer on a numeric keypad, no multiple choice. Difficulty scales from simple addition to multiplication 12×12 on hard mode. Forces 30-60 seconds of real cognitive engagement.

Alarmy Math: multi-step arithmetic problems. Solid, but on easier difficulties the addition can be solved on autopilot. Alarmy also offers memory recall and typing missions that fill the same niche.

Physical missions

ByeBed Push-ups: 5, 10, or 20 push-ups counted via the front camera using Apple Vision body pose. 100% on-device, no video uploaded. Real rep counting, not motion-only.

Alarmy Squat / Shake: accelerometer-based. Counts movement, not actual form. A wrist flick or vigorous shaking can complete the mission without actually doing the exercise.

Photo missions

ByeBed Photo: 3 modes (random object, sky, made bed) each verified by an AI recognition model (Google Gemini). No QR code, no reference photo, no pre-setup. Take any photo that matches the prompt and it passes.

Alarmy Photo: pixel-matching. You set a reference photo the night before (your kitchen sink, your shower, anywhere away from bed), and you have to retake it from a similar angle in the morning. Works, but needs planning. Alarmy also offers QR and barcode missions as alternatives.

Frequently asked questions

Is Alarmy better than ByeBed?

Alarmy is better if you need Android support, the largest review base, or sleep tracking bundled in. ByeBed is better for iOS users who want OS-level alarm enforcement and camera-based push-up verification.

How many missions does Alarmy have?

Alarmy offers 12+ mission types: math, memory, squat, shake, typing, barcode, QR, photo (pixel-match), walk steps, pinch, and more. ByeBed offers 12 missions but with native Apple Vision body pose and AI photo recognition.

Is ByeBed worth switching from Alarmy for?

Switch to ByeBed if you want alarms that ring on silent mode, cannot be canceled, and use camera-based push-ups. Stay with Alarmy if you need Android or are heavily invested in their ecosystem.

Does Alarmy work without ads on the free tier?

Alarmy's free tier shows ads regularly. The Premium subscription removes them. ByeBed has no ads at all — free tier or premium.
