Read full description

Ynter is a free interval timer that speaks the language of LLMs. No subscriptions. No "Pro" tier. No locked screens. Every feature in Ynter is unlocked from the moment you install — including the ones below. If the app earns a spot in your week, an optional tip jar is how you say thanks. That's the whole business model. Bring your own coach: any LLM Ynter reads a simple JSON lesson format. That means you can ask ChatGPT, Claude, Gemini, or any other model to design a workout for you — "give me a 25-minute kettlebell EMOM for shoulders," "build me a beginner yoga flow with long holds" — copy the result, paste it into Ynter, and run it. Your training plans live with you, not behind someone's API key. There's a built-in import sheet with the prompt format ready to go. Hand it to your LLM of choice and you have a tailored workout in under a minute. Built-in lessons to start with Don't want to prompt anything? Ynter ships with ready-to-run routines: • HIIT & Tabata — 45/15, 20/10, classic intervals • Yoga flows — long holds with gentle pacing • Strength sets — work, rest, rounds, done • Quick warm-ups — six minutes when that's all you've got A real editor for custom workouts Prefer to build by hand? The lesson editor lets you set every step's name, work time, rest time, and rounds. Tap any duration to type an exact value on the number pad. Save it, run it, share it. Reps for strength and machine work Not everything is a countdown. Switch a step to reps and Ynter drops the work timer — do the set at your own pace and tap "Done" when you're finished. Only the rest is timed. Perfect for the weight room, on iPhone and Apple Watch. Edit with Apple Intelligence On devices with Apple Intelligence, rewrite a lesson right in the editor: "double all rests," "add a cool-down," "turn this into a 20-minute session." The on-device model rewrites the lesson privately and offline — nothing leaves your device — and you review the result before saving. Live Activity & Dynamic Island Glance at your phone face-down on the bench: current interval, round, and time remaining sit right on the Lock Screen and in the Dynamic Island. No unlock needed. Apple Watch app, included Lessons sync to your wrist. Haptics fire on the Watch. Sessions keep running even if your phone is across the room. iCloud sync across every device Build a lesson on your Mac, run it on your iPhone, finish it on your Watch. Same routines, every screen. Voice cues that respect your music Spoken countdowns ride along on top of whatever you're listening to instead of cutting it. Mute the voice and you still get a bell and a haptic tap. Premium voices supported when installed. iPhone, iPad, Mac, and Apple Watch Built in SwiftUI for every Apple platform you own. What you get — all free: • Paste-in JSON lesson import (works great with any LLM) • Built-in HIIT, Tabata, yoga, and strength lessons • Custom lesson editor with work/rest/rounds — plus rep-based steps and exact number-pad entry • Apple Intelligence lesson editing (on supported devices) • Live Activity & Dynamic Island • Apple Watch app with haptics • iCloud sync across iPhone, iPad, Mac, and Watch • Spoken interval cues with music ducking • Background audio • No ads. No tracking. No subscriptions. No paywalled features. Optional tip jar if you want to support development. Get the workout your AI just designed. Ynter will count.

Rounds is an interval timer that doesn't hold features back. Everything is free — unlimited timers, compound timers, the coach voice, music, widgets, Apple Watch and Apple Health. A REAL COACH Liam calls every round, every interval and what's next — 400+ exercises, from burpees to the Pilates hundred — "Round 3 of 8! Work!", "Next up: squats!" — over your music, with the screen locked. BUILD ANY WORKOUT • HIIT, Tabata and circuit builders • Custom timers with repeating groups inside groups • Change every work or rest interval at once • Folders and search — drag timers to rearrange them, or drop one on a folder to file it • Starter workouts: Tabata, HIIT, the 7-Minute Workout, a Pilates mat class, EMOM, boxing rounds and focus sessions IN CONTROL MID-WORKOUT Jump straight to any interval from the list on the workout screen — handy when a class runs long or short. Pause, skip back or skip ahead any time. START WITHOUT OPENING THE APP • Home Screen and Lock Screen widgets start a timer in one tap • Siri and Shortcuts: "Start Tabata in Rounds", "Start a 5 minute countdown in Rounds" YOUR MUSIC Works with whatever you're playing — Spotify, Apple Music, podcasts. The music dips while the coach talks, can pause on every rest, and pauses with the workout. Or pick an Apple Music playlist for any timer. ACTIVITY AND STREAKS Every workout lands in your history: your day streak, this week's minutes and a month calendar in your timers' colours. Workouts from your Apple Watch count too. SHARE A TIMER Send any timer as a link or a QR code. Friends open it and add it to Rounds in one tap. WITH THE PHONE IN YOUR POCKET The timer keeps running, beeping and talking with the screen off.

Tap the next interval to skip ahead. APPLE HEALTH Finished workouts are saved to Health with the workout type you choose. ALSO A one-tap countdown for rest between sets, and a stopwatch with laps.
