Period Synced vs JabBell

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.
