Metta Timer: train, sit, brew. A beautifully crafted interval timer for physical training, meditation, and mindful daily rituals. Set a different photo for every interval — your meditation cushion, the trail ahead, the tea kettle, the stance you're holding — and let each phase of your practice have its own visual anchor. PHOTO BACKGROUNDS FOR EVERY INTERVAL This is what makes Metta Timer different. Assign your own image to each interval in a timer. Not one wallpaper for the whole session, but a unique photo per phase. Warm-up, work, rest, cool down: each can show the image that keeps you focused. Photos display on the Current screen and in Zen Mode fullscreen, with a subtle progress bar so you always know where you are. Share timers with photos embedded in `.mttimer` files so friends and students see your setup before they import. TRAIN Build custom interval sequences with groups and rounds. Chain phases together, each with its own duration, sounds, spoken cues, and photo. Keep your eyes on your practice, not your phone. SIT Gentle temple bells mark your meditation transitions. No jarring alarms. A photo of your altar during sitting, incense or candle visuals during transition, whatever helps you stay present. Swipe to change animated visuals without breaking your session. BREW A mindful bell when your patience is rewarded. A photo of the cup while the water steeps. Set it and forget it. SCHEDULE MODE Plan intervals by clock time, not just duration. Set start and end times for each phase, ideal for a morning routine, timed tea steps, or a class on a schedule. The timer waits until the right moment and can join mid-schedule if you open the app late. SIX ANIMATED VISUALS PLUS PHOTO Breathing Circle, Spiral Incense, Vertical Incense, Diagonal Incense, Hourglass, and Burning Candle, each crafted with care. Or choose Photo on any interval. Mix freely: photo for meditation, hourglass for exercise, candle for cool-down, all in one timer. ZEN MODE Tap the fullscreen icon for a distraction-free screen. Animated visuals fill the darkness; photo intervals go edge-to-edge with time and progress along the bottom. Swipe to cycle styles mid-session. Tap anywhere to exit. TEXT-TO-SPEECH Type any phrase and hear it at the start or end of any interval. Customize voice, speed, and pitch. Works with voice packs on iPhone and Android. SOUNDS Bell, Chime, Gong, Beep, Singing Bowl, Temple Brass Bell, Temple Bell, Temple Chime, Wooden Fish (1x and 3x), Big Temple Bell, Giant Temple Bell. Import your own MP3, M4A, WAV, or AIFF files. TIMER BUILDER Unlimited timers and intervals. Groups organize phases with independent round counts. Per interval: name, duration, color, sounds, announcements, animated visual or photo. Duplicate presets with one tap. Reorder with drag and drop. STREAKS AND HISTORY Completed timers are recorded automatically. Track consecutive practice days, total completions, and total time. Delete individual records anytime. SHARE Send any preset as a `.mttimer` file via AirDrop, Messages, email, Quick Share, or any app. Photos travel with the timer. Recipients preview everything before importing. PRESETS One Minute of Silence, Chan (Zen) Meditation, Brew High Mountain Green Tea, Horse Stance, Kung Fu Stances, and HIIT Training, ready out of the box. Set any preset as your default. BACKUP AND RESTORE Export presets and completion history as JSON. On Android, files save to Downloads automatically. Import presets or merge history onto a new device. PRIVACY All data stays on your device. No accounts. No ads. No tracking. Ever. PERFECT FOR Meditation, mindfulness, breathwork, yoga, HIIT, circuit training, martial arts, tea ceremony, kung fu, qi gong, taiji, Chan, Zen, Pomodoro, and any practice where a picture is worth a thousand reminders. Made with love and care by Metta Grove.

Sound Cue is a custom interval timer for workouts that need more than a last-second beep. Place spoken countdowns or beep cues exactly where you need them—early enough to prepare, change equipment, reset, or breathe before the next effort. BUILD EACH PART OF YOUR WORKOUT Choose how many timed work intervals (reps) and sets you want, then time Get Ready, Work, Rest, and Between Sets independently. Build a simple round timer or use Sound Cue for HIIT, Tabata, boxing, circuits, mobility, cardio, climbing, and more. PLACE CUES WHERE YOU NEED THEM Add up to five sound cues to each workout part: Get Ready, Work, Rest, or Between Sets. For each cue, choose a beep or spoken number. Each cue can play once, every second as a countdown, or on a custom repeating schedule. Set when it begins and whether repeating cues stop after a chosen count or continue until that workout part ends. FOLLOW ALONG BY SOUND Start the timer and stay focused on your workout. Phase announcements and scheduled cues tell you when to work, rest, and reset without checking the screen. STAY IN THE FLOW • Track time remaining, the current set and rep, completion percentage, and the next interval at a glance. • Choose beep or voice alerts—or turn them off—for interval changes and workout completion. • Adjust sound volume, turn haptic feedback on or off, and choose whether cues briefly lower music or other audio. • Hear scheduled cues while your iPhone is locked or while using another app. SAVE AND ORGANIZE WORKOUTS The free library starts with three included workouts and holds up to five saved workouts in total. Rename, reorder, edit, and reuse them. Use named groups to keep related workouts together and easy to find. A one-time in-app purchase expands the limit to 100 saved workouts. PRIVATE BY DESIGN Sound Cue has no ads, analytics, or tracking. Workouts, cues, and preferences are stored locally and are not transmitted by Sound Cue. Build your intervals, press Start, and let Sound Cue keep you moving.
