A fast, colorful timer for the things you do in chunks — and the things you do until you're done. Intervals, Pomodoro, and open-ended flow sessions. 168 palettes. WHY PULSE Every interval timer looks the same — red background, green active state, none of it yours. And they all only count down, so when the work doesn't fit a fixed box you fight the timer. Pulse counts both directions, brightly, and gets out of your way. Big numbers. Live Activity. Apple Watch. $3.99 once unlocks it all. FLOW MODE (NEW) A flow session counts UP. Focus until you decide to stop; the break you earn is proportional to the focus you put in. • Tap START and go — no countdown, no cap • Tap BREAK for focus ÷ 5 (or ÷ 4, or ÷ 3). 50 minutes of focus earns a 10-minute break • Optional target: a chime when you reach it, then it keeps counting — it never stops you • Optional reminders every 5, 10, 15, 20 or 30 minutes: a soft tick and a haptic • Works locked: the count-up rides your Lock Screen and Dynamic Island, cues still fire 168 PALETTES, SEARCHABLE • Coral — bright red + lime + black (the classic) …and 167 more. Search by color ("orange"), vibe ("neon", "calm"), or era ("70s"). Eight ship free; the one-time unlock opens all 168 and repaints the whole app instantly. TWO TAPS TO START Pick Interval or Flow, set three simple controls, tap Start. Or open the Library for a template: • Flow Session, Flowmodoro 25, Deep Work 90 — the new flow templates • Tabata — 8 × 20s work / 10s rest • Pomodoro — 25/5 focus cycle • Boxing Rounds — 3 min / 1 min corner Save any setup as a named timer — one tap next time.

The message lists the rounds, work and rest times and total time, with a link to Pulse. • After a few finished sessions, Pulse may ask once per version for an App Store rating. It never asks in the first 3 days, during a run, or within a day of the unlock screen. ### 1.4.1 — 2026-10-07 ## What's New ``` • Pulse now sends anonymous usage counts to our own server: which screens are opened, when a timer starts and finishes, and whether the unlock screen led to a purchase. Never your timer names, labels or anything you type. No account, no ad tracking. Settings > About and trypulsetimer.com/privacy list exactly what is sent. • FIXED: cancelling the App Store purchase sheet no longer shows an error message. ``` ## What changed - Tundra Signals (TundraKit 0.5.4, product TundraKit only) configured as app `pulse`, endpoint https://growth.tundra.industries, key from `ios/Config/Secrets.xcconfig` (gitignored). No key = no analytics. - PrivacyInfo.xcprivacy: Product Interaction, Device ID, Coarse Location; all Analytics, not linked, not tracking. - Paywall: a purchase cancelled or deferred (Ask to Buy) through a thrown RevenueCat error is handled quietly instead of showing an alert. ## App Privacy (publish before submitting) Data Used to Track You: none. Data Not Linked to You: - Usage Data > Product Interaction: Analytics - Identifiers > Device ID: Analytics - Location > Coarse Location: Analytics ### 1.4.0 — 2026-10-02 A calmer Pulse, rebuilt for iOS 26 with Liquid Glass. • NEW: Two taps to start. Pick Interval or Flow, set three simple controls, tap Start. No more crowded home screen. • NEW: One countdown ring around the big numbers. When an interval ends the whole screen floods to the next color with a firm haptic. • NEW: Liquid Glass controls everywhere: pause, skip and end float over your palette; the tab bar tucks away while you scroll. • NEW: Your saved timers and templates live in one Library, a tap away. • NEW: A redesigned unlock screen. Same prices: $3.99 once, or $9.99 to support. • FIXED: turning beeps or haptics off in Settings now takes effect in every timer. Pulse 1.4 needs iOS 26. Still no subscription, no ads, no analytics, no account. ### 1.3.0 — 2026-09-14 FLOW — the release for work that doesn't fit a box. • NEW: Flow mode — a session that counts UP. Focus until you're done, then tap BREAK and Pulse gives you the break you earned (focus ÷ 5, or ÷ 4, or ÷ 3 — your setting). • NEW: Optional target with a chime when you reach it. It never auto-stops you. • NEW: Optional focus reminders every 5, 10, 15, 20 or 30 minutes — one soft tick and a haptic. • NEW: Flow templates — Flow Session, Flowmodoro 25, Deep Work 90 — plus a Flow chip in Quick Start. • NEW: Labels — tag a timer Work, Study, Gym, Boxing, or anything you type, and see time by label. • NEW: History — every session grouped by day with duration, rounds and outcome, plus a tap-through detail. Free keeps 7 days; Pro keeps everything. • NEW: Streak — days in a row with a finished session. • NEW: Export CSV (Pro) — your whole history in one file. • NEW: Shortcuts + Siri — "Start a flow in Pulse", "Start my Boxing Rounds in Pulse". • NEW: Control Center / Lock Screen button — "Start Flow" in one tap (iOS 18 and later). • Flow rides the Lock Screen and Dynamic Island as a count-up Live Activity, and the cues still fire while you're locked. • NEW: 32 more palettes in four families — Gemstones (Ruby, Sapphire, Malachite…), Weather (Thunderstorm, Golden Hour, Aurora…), Gym (Court, Turf, Ring, Lane…) and Studio (Terminal, Library, Sepia, Typewriter…). 168 palettes total; eight are still free. • FIXED: the Lock Screen Live Activity now uses your chosen palette's colors for every palette. • FIXED: pausing an interval workout could leave it stuck — resume works again. Still $3.99 once. Still no subscription, no ads, no analytics, no account. ### 1.2.1 — 2026-07-12 • FIXED: the Lock Screen timer (Live Activity) now appears reliably, and cues keep sounding while your phone is locked • NEW: Apple Watch app — start timers from your wrist, palette-matched colors, haptic taps at every transition • NEW: Permissions in Settings — one tap jumps straight to Pulse's iOS settings • Unlock Pulse Pro from Settings, plus Restore Purchases • Palette browser: all 136 palettes, searchable — 8 free, Pro opens the rest • Cleaner finish screen with GO AGAIN ## Apps similar to Pulse | App | Rating | Price | Category | | --- | --- | --- | --- | | [Notch: GTG Watch Timer](https://appshunter.io/ios/app/notch-gtg-watch-timer/id6772011909) | — | Free | Health & Fitness | | [Circadian: Sunrise Sleep](https://appshunter.io/ios/app/circadian-sunrise-sleep/id6765873609) | — | Free | Health & Fitness | | [Interval Pulse Timer](https://appshunter.io/ios/app/interval-pulse-timer/id6786118364) | 5.0 (1) | Free | Health & Fitness | | [Pulse: Interval Timer](https://appshunter.io/ios/app/pulse-interval-timer/id6761445290) | — | Free | Health & Fitness | | [Stretch Timer - GetFlexy](https://appshunter.io/ios/app/stretch-timer-getflexy/id6749179535) | 3.5 (2) | Free | Health & Fitness | | [Routine Interval Timer - DDANG](https://appshunter.io/ios/app/routine-interval-timer-ddang/id6768160515) | — | Free | Health & Fitness | ## More apps by Lance Merrill - [Contrast Timer](https://appshunter.io/ios/app/contrast-timer/id6759400541) - [NoPuff - Quit Vaping](https://appshunter.io/ios/app/nopuff-quit-vaping/id6760631497) - [Love Taps: Couple Widget](https://appshunter.io/ios/app/love-taps-couple-widget/id6785731886) - [Ember: Memorial Widget](https://appshunter.io/ios/app/ember-memorial-widget/id6787486430) - [Ebb: Tides & Fishing Times](https://appshunter.io/ios/app/ebb-tides-and-fishing-times/id6787486679) All apps by Lance Merrill: https://appshunter.io/developer/1878453491 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
