AMRAP
As Many Rounds As Possible
Counts down to zero with an on-screen round/rep tally, halfway chime, and a final-10s count.
WOD & Interval Timer · iPhone & Apple Watch
The most beautiful timer your training will ever see
Squall is a functional-fitness timer for iPhone and Apple Watch that's instantly readable, never lies to you, and stays out of your way. Snap the whiteboard or read it into the app to build your workout, run the whole room off one clock, and keep heart rate and calories in Apple Health. The calm before the storm.
Signed & reviewed by Apple
Squall is delivered only through the App Store — every release is reviewed and code-signed by Apple, so the build you install is verified, untampered, and the right one for your device.
No account, no servers
There's no sign-up and nothing to hack — your workouts live on your device and, if you choose, in your own private iCloud.
Built native for iPhone & Watch
A true SwiftUI app made for iOS 18 and watchOS, so it stays fast, battery-light, and fully at home on your iPhone and Apple Watch.
01 — The Promise
Beautiful. Dependable. Quiet when it counts.
The leading timers win on features and lose on trust — cues firing while paused, hijacked music, dead batteries mid-WOD. Squall's wedge is the opposite: flawless on the three things that matter when you're out of breath.
Readable.
Honest.
Invisible.
02 — See It Run
Watch the storm break.
The screen is the signal
Warm on work, cool on rest — the whole color world floods on every phase change, so a glance tells you exactly where you are.
A ring that never lies
The depleting ring is driven by the workout clock, not a sleep timer, so it stays exactly true to the second.
Always knows what's next
A clear NEXT UP preview between stages means you're never caught off guard mid-workout.

03 — Every Timer You Need
Five timer types. One flawless engine.
For Time
Stopwatch with an optional cap
Counts up until you're done, captures splits, and auto-stops at a time cap if you set one.
EMOM
Every Minute On the Minute
Repeating intervals with a strong top-of-minute cue. Supports alternating A/B stations with labels.
Tabata
Work / rest intervals
Classic 20s/10s × 8 — or fully editable work, rest, rounds, and sets with distinct phase sounds.
Mix
Chain stages into one WOD
String countdown, AMRAP, rest, EMOM, and Tabata stages into one continuous workout with auto-advance and a next-up preview.
Saved
Build it once, keep it forever
Dial in any timer — or a full Mix — name it, and save it to your library so your go-to WODs start in a single tap.
04 — Scan or Speak
FreeGet the whiteboard into Squall in seconds.
Nobody wants to build a timer rep by rep while the class is warming up. Snap the board, say it, or type it — Squall works out what you meant and sets the clock.
Snap the whiteboard
Point your camera at the board and Squall reads the workout straight off it — rounds, reps, movements, and the cap.
Or just say it
Read the workout out loud the way your coach called it — “twelve-minute AMRAP, fifteen air squats, ten swings, five pull ups” — and it's set.
Or type it
Prefer your thumbs? Type it in shorthand and the same parser builds the timer. Then save it to your library so it's one tap next time.
The movements stay with you
Your rep scheme sits right on the running clock, so you never have to squint back at the board between rounds to remember what's next.
05 — Train Together
Pro to hostRun the whole room off one clock.
Start a class, call out the code, and every athlete's phone locks to your timer. Scores land on a live leaderboard — up on the gym TV, on their own screens, or both.
A four-digit code
Read the code out to the room. Athletes tap Train Together, type it in, and they're on your clock — no accounts, no app-store detour, no sign-up.
The whole room starts together
Every phone runs off the host's clock, so the class counts down, rests, and hits TIME as one — no drift between fifteen devices.
A live leaderboard
Rounds and reps update as athletes tap through. Put it on the TV, leave it on their phones, or do both.
Coach competes — or doesn't
Training alongside the class? Put your own score on the board. Coaching from the floor? Leave it off and just run the clock.
No echo in the room
Mute athletes' sounds so only your device plays cues — fifteen phones beeping a half-second apart is nobody's idea of a countdown. Haptics stay on, so everyone still feels the count.
Free to join, Pro to host
Anyone can join a class on the free tier. Hosting one — the code, the leaderboard, the big screen — is part of Squall Pro.
The big screen isn't just for classes
AirPlay any Squall workout to a smart TV and it lays itself out for the room — an across-the-gym clock with the phase color world behind it, not a phone screen stretched to fit. That works on a solo session, and it's free for everyone. The live leaderboard beside it is the part that comes with hosting a class.

Squall writes to Apple Health, so every session shows up alongside the rest of your activity — with real heart rate and calories when you wear your Watch.
Every workout counts
Save each session to Apple Health so it contributes to your daily activity — no Watch required, no Pro required.
Real heart rate & caloriesPro
Train with an Apple Watch and Squall records measured min / avg / max heart rate and active energy, on your results and in your log.
A smart estimate without a Watch
No Watch? Squall gives an activity-based calorie estimate — add your weight in Settings to make it more accurate.

08 — Progress
FreeProof that it's working.
Every workout you finish lands in your log. The Progress tab turns all of it into something you can actually read — the months you showed up, the weeks you went hard, and your best result on every workout you've come back to.
Streaks worth keeping
Your current streak, your best one ever, and every session you've logged — sitting at the top of the tab, not buried three taps deep.
A training calendar
Every day you trained, shaded by how hard. Months of consistency read in a single glance — and the gaps read just as honestly.
Weekly volume
The minutes you actually put in, week over week, so a heavy block and a light one are impossible to confuse after the fact.
Your records
Repeat a workout and Squall remembers. Each one keeps your best result with the number of attempts beside it, so progress is a fact rather than a feeling.
09 — Clock Faces
Pick the face that fits your training.
Every face floods the screen with a phase “color world” — warm on work, cool on rest — on iPhone and Apple Watch alike. Six to choose from, and counting.
Radial
A calm, quietly emptying ring — nothing to pull your focus.
Pride
A vivid dot field that blooms with each round.
Bold
Stacked numerals you can read from across the box.

10 — Built Like an Apple App
The details you only notice when they're missing.
Accurate, even locked
Cues keep firing with the screen locked or the app in the background, scheduled against the workout clock so timing never drifts.
Voice & sound cues
Beeps, spoken cues, or both — rendered on-device. Countdown, halfway, work/rest, and an unmistakable GO and TIME.
Haptics
A clear haptic vocabulary mirrors every audio cue, so they land even with music loud and the phone face-down on a bench.
Your music, untouched
Squall mixes with Spotify, Apple Music, or a podcast and only ducks briefly for a cue — it never seizes the audio route.
Private by design
No accounts, no servers. Workouts live on your device and, if you choose, sync through your own private iCloud.
Accessible & hands-free
Full VoiceOver, Dynamic Type, and Reduce Motion support — plus Siri control to start, pause, or end a workout.
Works everywhere you train
On your Apple Watch
A standalone Watch app — start and run a full workout from your wrist, no phone in hand. (Pro)
In the Dynamic Island
A redesigned Live Activity keeps the timer and progress bar ticking live — rock-solid, even locked. (Pro)
On the Lock Screen
The branded countdown never freezes when your phone locks — a glance shows exactly where you are. (Pro)
On the gym TV
AirPlay any workout to a smart TV and Squall lays itself out for the room — not a stretched phone screen.

12 — Questions
The honest answers.
No. Squall mixes with whatever you're playing — Spotify, Apple Music, a podcast — and only ducks the volume briefly for a cue, then hands it back. It never seizes the audio route.
Never. Pause means silence is a hard guarantee — no scheduled cue can fire while the timer is stopped. Cues are scheduled against the workout clock, so they can't drift or double up either.
No accounts, no sign-up, no servers. Your workouts live on your device and, if you turn it on, sync through your own private iCloud that only you can access.
Yes. AirPlay Squall to any compatible smart TV or Apple TV and it lays itself out for the big screen — an across-the-gym clock with the phase color world behind it, rather than your phone screen stretched to fit. It's free for everyone, and it works on a solo session, not just a class. If you're hosting a class, the live leaderboard sits alongside the clock.
Yes — that's Train Together. Start a class, read out the four-digit join code, and every athlete's phone runs off your clock, so the room counts down, rests, and hits TIME as one. Rounds and reps feed a live leaderboard you can put on the gym TV, leave on athletes' phones, or both. Hosting a class is part of Squall Pro; joining one is free.
No. Anyone can join on the free tier — all they need is the code. Pro is only for the person hosting. You can also mute athletes' sounds so yours is the only device playing cues; haptics stay on, so everyone still feels the count.
No. Snap a photo of the gym whiteboard, say the workout out loud, or type it in shorthand — Squall works out what you meant and builds the timer. The movements then sit on the running clock, so you're not squinting back at the board between rounds. That's free for everyone.
Yes. Squall is distributed only through the App Store, where every release is reviewed and code-signed by Apple. That means the version you download is verified and untampered, runs in iOS's secure sandbox, and is always the build made to be compatible with your device.
Yes. Squall is fully native and runs entirely on your iPhone — no connection required to set up or run any workout.
Yes — the standalone Apple Watch app is part of Squall Pro. Start and run a full workout from your wrist with no phone needed: pick a timer, tune it with the Digital Crown, and go, with haptic and voice cues on-wrist. It records real heart rate and calories, and everything syncs back to your iPhone history automatically.
Yes. With Squall Pro on an Apple Watch, it records measured min / avg / max heart rate and active energy to Apple Health. Without a Watch, it gives an activity-based calorie estimate — add your weight in Settings to sharpen it. Either way, every workout can be saved to Apple Health for free.
If you turn it on, yes. A quick step during onboarding (or the Apple Health page in Settings) lets Squall write each session to Health so it counts toward your daily activity. That's free on iPhone — the Apple Watch app, with real heart rate and calories, is part of Squall Pro.
That's the Progress tab. It keeps your current and best streak alongside your total workouts, a training calendar shaded by how hard you went, and your weekly volume in minutes. Repeat a workout and Squall holds on to your best result with the number of attempts beside it, so you can see the difference rather than guess at it. All free.
Not currently — Squall is a native iOS app. Android isn't on the roadmap for v1.
