Ferrum vs AdaptHer

Strength training built around your cycle. Because the best athletes don't ignore their biology — they train with it. —— TRAIN WITH YOUR CYCLE, NOT DESPITE IT Your hormones are the most underused performance tool in women's fitness. Ferrum tracks your Menstrual, Follicular, Ovulatory, and Luteal phases and uses them to drive every recommendation — from load adjustments to rest guidance to when to attempt a PR. —— GUIDED WORKOUTS THAT ACTUALLY ADAPT Follow a step-by-step guided session or log freely in manual mode. Navigate exercises like a playlist — skip ahead, go back, track each set individually with different weights and reps. Your workout saves as you go, so nothing is ever lost. —— KNOW WHEN TO PUSH. KNOW WHEN TO RECOVER. Ferrum's progressive overload engine monitors your performance history and your cycle to flag peak strength windows automatically. When your body is primed for a personal best, Ferrum tells you. When it needs recovery, Ferrum tells you that too. —— BUILT FOR WOMEN WHO LIFT Not a wellness app. Not a step counter. Ferrum is a serious training tool — weekly splits, PR tracking, progress photos tied to your cycle phase, and coaching that understands your biology. Your body has a rhythm. Train like it.

AdaptHer is a cycle-aware training app that helps women run and lift in sync with their biology — building strength when the body is primed, and protecting recovery when it's not. Women's physiology changes across the menstrual cycle. AdaptHer reads where you are in your cycle, layers on how you recovered last night, and gives you one workout matched to today — then explains why. It's not a tracker that logs your cycle; it turns your cycle into a plan. HOW IT WORKS Where you are in your cycle, plus how you recovered last night, equals today's workout. That's the whole engine. AdaptHer adjusts intensity, volume, and recovery to the day in front of you — running, lifting, or both. WHAT YOU GET - A daily session matched to your phase, readiness, and goal - Hard days when your body can take them; easier days when it can't - A short morning briefing explaining the "why" behind today - Cycle and physiology education — the science, not folklore WORKS FROM YOUR CYCLE ALONE No wearable required. If you do wear an Oura ring, AdaptHer sharpens each day by factoring in how recovered you actually are. ON THE PILL OR HRT? There's a setting for it. Hormonal contraception flattens the natural hormone curve, so AdaptHer leans more on your readiness signals and a steadier baseline. YOURS, PRIVATELY Your cycle and health data is never sold. A limited summary (phase, readiness signals, today's workout) is sent to generate your morning briefing — never used to train any AI model. Export or delete your data whenever you want. Built with women, for women — grounded in physiology.
