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

Last updated: May 26, 2026

Quick answer: Revy is the alarm built around hard puzzles — slide tiles, logic grids, or pattern-matching tasks designed to demand sustained cognitive effort. ByeBed is the iOS-native option built on iOS AlarmKit, with 12 mission types across cognitive, physical, and visual modes, and an alarm Apple itself prevents from being canceled. If pure puzzle difficulty is what wakes you, Revy. If you want mission variety beyond puzzles and the strongest snooze prevention on iOS, ByeBed.

What Revy does well

Revy commits to puzzles. Where many alarm apps treat the dismissal task as an afterthought, Revy treats it as the entire product. The puzzles are typically deeper than the math prompts found in competitors, requiring genuine pattern-matching, logic, or multi-step reasoning before the alarm stops.

For users whose brains light up in response to puzzles — especially people who do crosswords, Sudoku, or chess puzzles to wake up — Revy is a culturally natural fit. The difficulty calibration also matters: most apps cap at "simple addition," while Revy offers genuinely hard tasks.

If you've already tried physical and photo missions and find them either too easy to cheat or not engaging, a difficult puzzle is a legitimate alternative path to defeating sleep inertia.

Where Revy falls short

Puzzle-only is a niche, not a strategy for everyone:

• Mission variety is thin. Based on its App Store description, Revy concentrates on around 4 puzzle variants. ByeBed offers 12 — push-ups, math, photo of sky, photo of made bed, drawing, maze, Snake, Flappy Bird, memory pairs, memory sequence, shake, and random-object photo. Variety prevents adaptation.
• No physical activation. Sleep inertia research (Trotti, 2017) identifies both cognitive AND physical activation as effective interventions. A puzzle is purely cognitive — your body stays in bed. ByeBed's push-up missions force you upright.
• Hard puzzles can backfire. When the puzzle is too hard for a half-asleep brain, frustration leads to giving up and snoozing harder. ByeBed's variety lets you pick a mission that matches your morning capacity.
• Alarms run at the app level. Revy is not built on iOS AlarmKit. A force-quit or aggressive iOS battery management can prevent the alarm from ringing reliably.
• A cancel option exists. Because the alarm is app-level rather than OS-level, the cancel path is exposed — exactly what a frustrated, half-asleep brain looks for when stuck on a hard puzzle.

Why ByeBed is better for heavy sleepers

Heavy sleepers — defined as people who routinely hit snooze 3+ times or sleep through alarms — need three things Revy does not fully deliver:

1. OS-level alarm enforcement. ByeBed is built on iOS AlarmKit (iOS 26+). The alarm rings even on silent and Do Not Disturb. Force-quitting the app does nothing. Revy runs at the app level and depends on the app staying alive.
2. No cancel button. Apple's AlarmKit framework does not allow a cancel button on the alarm UI. The only way to stop it is to complete the mission. Revy exposes a cancel path.
3. Camera-verified physical missions. Push-up missions use Apple Vision body pose detection, all on-device. The app counts your real reps. Revy is puzzle-only — your body never has to leave the mattress.

The mission engine, compared

Both apps demand cognitive engagement. But ByeBed pairs cognitive missions with physical and visual ones.

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. Memory Cards and Memory Sequence add sustained pattern recognition.

Revy puzzles: deeper than typical alarm-app math. Genuine puzzle difficulty is Revy's strongest argument — if the puzzle wakes you, it wakes you well.

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.

Revy physical: not part of the catalog. Revy is puzzle-only, which means your body never has to leave the bed to dismiss the alarm.

Photo missions

ByeBed Photo: 3 modes — random object, sky, made bed — each verified by an on-device recognition model. No QR code, no pre-arranged stickers, no spoof possible by photographing a screenshot.

Revy Photo: not part of the catalog. Revy's verification is purely screen-based — solve the puzzle on the device, dismiss.

Frequently asked questions

Is Revy better than ByeBed?

Revy is better if you specifically want hard puzzles as your dismissal mechanic. ByeBed is better for iOS users who want mission variety (cognitive, physical, photo), OS-level alarm enforcement, and camera-based push-up verification.

How many missions does Revy have?

Revy centers on around 4 puzzle variants. ByeBed offers 12 missions across cognitive, physical, and visual modes.

Is ByeBed worth switching from Revy for?

Switch to ByeBed if puzzle-only feels too narrow and you want physical or photo missions too. Stay with Revy if pure puzzle difficulty is what activates your brain in the morning.

Are ByeBed puzzles as hard as Revy's?

ByeBed's hard mode math (multiplication 12×12) and Memory Sequence missions are genuinely difficult. Revy may push deeper into puzzle complexity since it is its sole specialty, but ByeBed compensates with physical and photo missions that Revy lacks entirely.
