Most timers count to zero. FulwaveTimer runs your whole routine β€” built from stages, each with its own length, color, and most important sound. Intervals, Pomodoro focus blocks, breathing exercises, a speech you're rehearsing, a sleep wind-down: set the structure once, press play, and follow along by sound, on your Lock Screen, or from your wrist. BUILD IT YOUR WAY β€’ Multistage timers β€” add as many stages as you like, each with its own duration and color. β€’ Per-stage sound β€” play an audio track you own, or have the app read text aloud with a voice and speed you choose. β€’ Independent transitions β€” set how each stage's audio starts and ends on its own: Cut, Fade, or Crossfade into the next stage. β€’ Per-stage haptics and alert tones, plus a spoken 10-second warning or 3-2-1 countdown. β€’ Repeat a single stage, or loop the whole playlist β€” perfect for HIIT rounds, Pomodoro cycles, and breathing sets. β€’ Start fast from built-in templates: Pomodoro, HIIT, Box Breathing, Meditation, and more. ON-SCREEN TEXT FOR SPEECHES β€’ Show a stage's text on the Player and scroll it in time with the reading β€” a simple teleprompter for practicing a talk. VOICE-OVERS, IN YOUR VOICE β€’ A session can carry its spoken words as text rather than baked-in audio, so your device reads them over the stage's music in any voice you have installed β€” including another language. β€’ Set the voice and the speed, or turn speaking off and read along on screen. Yours to adjust even in a locked session. STAY IN CONTROL, EVERYWHERE β€’ Live Activity and Dynamic Island show your session on the Lock Screen with a glanceable countdown. β€’ A Quick Start Home Screen widget launches a playlist with one tap. β€’ On-time stage notifications announce each new stage by name. β€’ Lock Screen and headphone controls to play, pause, and skip. APPLE WATCH + APPLE HEALTH β€’ A live timer on your wrist with stage, countdown, and controls. β€’ Record your session as a workout in Apple Health β€” with heart rate, active energy, and the workout type you set on the playlist. β€’ Wrist haptics fire at every stage change, even with the screen off. YOUR LIBRARY, SAFE AND IN SYNC β€’ iCloud keeps your playlists in sync across your devices, privately. β€’ Color-tag playlists to organize your library. β€’ Export and import playlists. β€’ Automatic backups with one-tap restore β€” the newest also kept in your own iCloud account, so it survives a reinstall. β€’ A shared session puts its own audio back on your other devices, or after a reinstall. MADE TO FIT YOU β€’ Custom accent, background, and text colors; Dynamic Type and VoiceOver throughout. β€’ Design your Player: movable widgets, eight clock styles. β€’ A simplified Playback-Only view when you just want to press play. β€’ Works on iPhone, iPad, and Apple Silicon Mac. FULWAVE PRO FulwaveTimer is free to use, and keeps a small library at no cost. Fulwave Pro unlocks an unlimited playlist library and session export. Pro is available as a monthly subscription with a 7-day free trial, or a one-time lifetime purchase. SHARE COMPLETE SESSIONS Bundle a playlist together with its audio into a single .fws session file and share it. Anyone can open and play a session they receive; Fulwave Pro keeps imported sessions in your library permanently. FULWAVE DESIGNER FOR MAC Fulwave Designer is a free companion app on the Mac App Store. Build a session on a big screen: layer several audio tracks and spoken-text cues on a single stage, set each layer's start delay, gain, and pan, choose haptics and stage colors, add session artwork, and audition it all on a transport. Export a .fws session β€” optionally locked, so it plays exactly as you built it β€” to play or share here. Sessions you receive open and play for free; Fulwave Pro keeps them in your library. No accounts. No ads. No tracking. Your data stays on your devices.
