Period Synced vs Cycle Sync Running Coach

Train with your cycle, not against it. Period Synced is a workout interval timer that adapts your training intensity to where you are in your menstrual cycle. It's a precision gym timer first — with phase-aware suggestions layered on top. If you've ever wondered why some weeks every set feels light and other weeks the same warm-up wrecks you, your hormones are part of the answer. Period Synced helps you read that signal and time your effort accordingly. WHAT YOU GET - A full-featured workout interval timer - HIIT, Tabata, EMOM, AMRAP, For Time, and fully custom interval sequences - Smooth circular timer with crisp audio cues and haptic feedback - Phase-aware intensity suggestions for every workout - Cycle visualization with a four-phase ring you can read at a glance - Curated workout library organized by cycle phase - Workout history with stats, streaks, and progress charts - Six languages, dark-mode friendly palette, clean modern interface TIMER MODES HIIT — set work, rest, and rounds. Get a 3-2-1 countdown and bell on every interval change. Tabata — classic 20 / 10 protocol, 8 rounds, ready in one tap. EMOM — every minute on the minute, with a clear interval indicator. AMRAP — as many rounds as possible, with a clean countdown. For Time — count up, track your PR. Custom — build any interval sequence you want, name each segment, save it. CYCLE PHASE INTELLIGENCE The four phases of the menstrual cycle each shift your energy, recovery, and strength capacity. Period Synced calculates your current phase from your last period start and suggests how to train: Menstrual — lower intensity, mobility, gentle movement, recovery focus. Follicular — energy rising. Strength building, progressive overload, new challenges. Ovulation — peak performance window. Sprints, heavy lifts, personal records. Luteal — winding down. Steady cardio, moderate strength, more recovery between sessions. These are guidance, not rules. Skip them, override them, or use them as a starting point — the timer works on its own. WORKOUT LIBRARY Twelve curated templates organized by phase. Mobility flows for your menstrual phase. Strength builders for your follicular phase. HIIT peak-power sessions for your ovulatory window. Steady endurance for your luteal phase. Tap to load any template straight into the timer. INSIGHTS Track total workouts, active minutes, current streak, and most active phase. See your weekly activity chart and phase distribution. Build a picture of how you actually train across a full cycle. PRIVACY FIRST Your cycle data lives on your device. No account required. No sign-up. No third-party data sharing beyond what's required to deliver ads — and you control that with a built-in consent center you can change any time. SIX LANGUAGES English, Spanish, French, Italian, German, Portuguese. WHO IT'S FOR People who lift, run, do HIIT, train for events, or just want a clean interval timer with one more layer of intelligence on top. If you menstruate and you train, this is built for you. If you don't, the timer still works beautifully — the cycle layer is opt-in. IMPORTANT This app provides general fitness guidance, not medical advice. It is not a contraceptive aid and should not be used to predict fertility. Consult a qualified healthcare provider for medical questions about your cycle or training.

Some weeks you feel unstoppable. Others, a 5k feels like a marathon. That's not a lack of discipline — it's your cycle, and most training plans ignore it completely. Cycle Sync builds your running week around where you actually are this month. CYCLE-AWARE TRAINING With Premium, your plan shifts with your phase. Quality sessions stay as written in the follicular and ovulatory phases. Volume over intensity through the luteal phase. Gentle, honest days when you're bleeding — never a hard session prescribed on a day your body is doing something else. Training for a 5k, 10k, half or marathon? Your week periodizes toward race day — base, build, peak, taper — and race day itself never moves. ADAPTS WHEN YOU DO Log how you feel in seconds — energy, cramps, sleep, flow. With Premium, your week adjusts around it. Missing a run or easing off isn't failure and Cycle Sync never treats it that way. No streaks to break, no guilt, no red rings shaming you. AN AI COACH THAT KNOWS YOUR WEEK Ask anything. "I have terrible cramps today." "Why is today easy?" "Can I move my long run to Sunday?" Your coach knows your phase and your plan, explains every change in one plain sentence, and can reshuffle your week on request. It tells you the real reason a day looks the way it does — not a generic tip. RUN TRACKING BUILT IN GPS route, distance, pace and cadence. Finished runs save to Apple Health alongside everything else. SAFETY THAT'S HONEST Let a trusted contact know when you head out, with a message you send yourself. A daylight cue when you're heading into dusk. No fake live-tracking promises. Free, always. SEE YOUR PATTERNS Every run is tagged with the cycle phase you were in. Once you've logged a couple of full cycles, Cycle Sync reads your own record back to you: which phases you run strongest in, how your energy and symptoms move through the month, and how many of your cycles each finding rests on. Never a study's average — your numbers. When a finding lands on a week that has a hard session in an unhelpful window, Cycle Sync offers to move it. One tap, free for everyone, and you can put it back. Monthly distance, pace and run trends. PRIVACY BY DESIGN Your cycle dates, symptom logs, routes and runs live on your iPhone and in Apple Health. There's no account — no email, no password, no profile on a server. We don't sell your data, don't run ads, and don't track you. To build your week and to answer you, Cycle Sync sends a short, anonymised summary — your phase, your plan, and how the last few weeks have trended — to an AI service. Never your name, your dates, your raw logs, or where you run. Setup shows you that summary and asks before any of it is sent; say no and your plan is built entirely on your iPhone. The privacy policy spells the rest out in full. FREE FOREVER Run tracking, period logging and safety sharing are free and always will be. CYCLE SYNC PREMIUM Unlocks the cycle-adaptive layer — every workout retuned to your phase and your logged symptoms — plus the conversational AI coach. Monthly or annual.
