Most timers count to zero. FulwaveTimer runs your whole routine — 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 • Multistage timers — add as many stages as you like, each with its own duration and color. • Per-stage sound — play an audio track you own, or have the app read text aloud with a voice and speed you choose. • Independent transitions — set how each stage's audio starts and ends on its own: Cut, Fade, or Crossfade into the next stage. • Per-stage haptics and alert tones, plus a spoken 10-second warning or 3-2-1 countdown. • Repeat a single stage, or loop the whole playlist — perfect for HIIT rounds, Pomodoro cycles, and breathing sets. • Start fast from built-in templates: Pomodoro, HIIT, Box Breathing, Meditation, and more. ON-SCREEN TEXT FOR SPEECHES • Show a stage's text on the Player and scroll it in time with the reading — a simple teleprompter for practicing a talk. VOICE-OVERS, IN YOUR VOICE • 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 — including another language. • 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 • Live Activity and Dynamic Island show your session on the Lock Screen with a glanceable countdown. • A Quick Start Home Screen widget launches a playlist with one tap. • On-time stage notifications announce each new stage by name. • Lock Screen and headphone controls to play, pause, and skip. APPLE WATCH + APPLE HEALTH • A live timer on your wrist with stage, countdown, and controls. • Record your session as a workout in Apple Health — with heart rate, active energy, and the workout type you set on the playlist. • Wrist haptics fire at every stage change, even with the screen off. YOUR LIBRARY, SAFE AND IN SYNC • iCloud keeps your playlists in sync across your devices, privately. • Color-tag playlists to organize your library. • Export and import playlists. • Automatic backups with one-tap restore — the newest also kept in your own iCloud account, so it survives a reinstall. • A shared session puts its own audio back on your other devices, or after a reinstall. MADE TO FIT YOU • Custom accent, background, and text colors; Dynamic Type and VoiceOver throughout. • A simplified Playback-Only view when you just want to press play. • 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 — optionally locked, so it plays exactly as you built it — 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.
