Rhythmus
Read full descriptionHide full description
Rhythmus is a period tracker with a cycle calendar โ plus a nutrition and training plan that changes with your cycle. WHAT RHYTHMUS DOES โข Cycle and period calendar: log your period, see your cycle day and phase at a glance, with estimated ovulation and fertile window โข Nutrition plan: meals and nutrients matched to your current phase โ omnivore, vegetarian, vegan โ with a shopping list โข Training plan: workouts scaled to your intensity and training days, logged set by set โข Supplements: which nutrients matter in which phase โข Daily energy check-in: feeling low, and the app suggests a gentler session โข Weekly overview, symptom diary, cycle statistics from your own history WHO IT IS FOR For women who train and notice that the same session feels easy one week and impossible the next. Menstruation, follicular phase, ovulation and the luteal phase each ask for something different โ Rhythmus takes that into account. NO ACCOUNT, NO TRACKING No sign-up, no registration, no ads, no subscriptions, no in-app purchases. Everything you enter stays on your device and is sent nowhere. The app works fully offline. From Settings you can export a backup at any time and restore it on another device. WITH SOURCES Every health statement in the app comes with a citation you can tap โ straight to the study or fact sheet. Among others from the Journal of the International Society of Sports Nutrition, the Journal of Medical Internet Research and the National Institutes of Health. Available in German, English and Spanish. Rhythmus is a free passion project. Note: Rhythmus is not a medical device, not a contraception method, and does not replace medical advice.

Verdict
The clearest difference is in-app purchases: Rhythmus at none against Paleo Fasting's 3. Rhythmus also leads on update cadence (every 2 days vs every 3 weeks) and iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.
