FitOn vs Lively: Two Free Fitness Apps for Women Compared

FitOn and Lively are both free, both aimed at women, and both useful in limited ways. The question is what you’re actually trying to accomplish.

FitOn built one of the largest free fitness content libraries available. Classes span cardio, HIIT, strength, barre, yoga, and more — led by a mix of certified trainers and recognizable names. The free tier is genuinely usable without hitting paywalls on basic content. FitOn PRO exists, but many users don’t need it to get real value from the app.

Lively is a different kind of tool. It’s not a workout app at all — it’s cycle education packaged into an app. It explains what each phase of your menstrual cycle means for your energy, recovery, and movement preferences, and suggests appropriate activity types. The suggestions are light: “try lower intensity today” rather than “here’s a 45-minute strength session.” It’s free, with no subscription or upsell.

Where Both Hit a Ceiling

FitOn’s library is wide but flat. You’re choosing classes based on mood and availability, not building toward anything. There’s no progressive structure, no week-over-week programming that builds on your previous sessions, and no awareness that your capacity changes across your cycle. You could do the same HIIT class in your follicular phase and your menstrual phase and the app would treat them identically.

Lively’s ceiling is its scope. It tells you what phase you’re in and what that typically means. It does not give you workouts. You’ll need FitOn, or YouTube, or a gym, or something else entirely if you want to actually train. Lively is a lens, not a program.

Using both together closes part of the gap — Lively gives you the hormonal context, FitOn gives you the classes. But you’re still doing the integration in your head. No app is connecting the cycle data to the training plan.

Where Ondara Fits

That integration is what we built Ondara to handle. Your phase determines your program automatically. During follicular and ovulatory phases, Ondara programs higher intensity and heavier loads. During luteal and menstrual phases, it shifts to recovery-focused work — not as a fallback, but as a deliberate part of the training cycle. There’s also a longevity track for women 40+ that focuses on bone density, muscle preservation, and joint health.

Ondara is $12.99/month or $89.99/year. Seven-day free trial, no credit card required.

Verdict

FitOn is the better choice if you want free workout content and variety. Lively is the better choice if you're just learning about cycle syncing and want phase-based guidance. For structured, cycle-aware programming, both fall short — they occupy different niches without fully serving either.
