Summary: Flo and Clue are cycle tracking apps that log symptoms and predict periods. MyFitnessPal is a calorie and macro counter. Atunelle is the only app that connects all three — tracking your cycle, calculating personalised macros from body measurements, adjusting food recommendations per cycle phase, and updating your workout programme every week automatically.
Note: Atunelle is the product brand (atunelle.com). On the Apple App Store and Google Play it is listed as Her Sense — same app, same features.
What each app actually does
Flo — cycle tracking and symptom logging
Flo is primarily a period and ovulation tracker. It predicts your next period and fertile window, lets you log symptoms, and includes educational articles on reproductive health. The app has a large user base — over 70 million users as of 2024 — and its predictions improve over time through pattern learning.
Flo does not include workout programmes, macro tracking, or food recommendations. The premium tier adds AI-powered health insights and the ability to share data with a doctor. Best for: women who want accurate period prediction and symptom logging.
Clue — science-led cycle tracking
Clue positions itself as the most scientifically rigorous cycle tracking app. Founded with research partnerships, it emphasises data accuracy, algorithmic transparency, and reproductive health education. Like Flo, Clue focuses on cycle prediction and symptom logging rather than fitness or nutrition.
Clue does not offer workout planning or food tracking. Its interface is minimal and its approach is data-forward. Best for: women who want clean, research-backed cycle tracking without additional features.
MyFitnessPal — calorie and macro tracking
MyFitnessPal is the most-used food logging app globally. It has a database of over 14 million foods, supports barcode scanning, recipe logging, and macro goal-setting. It provides calorie tracking, macro breakdowns, and integration with fitness wearables.
MyFitnessPal has no cycle awareness. Macro targets are set once and remain static — they do not change based on hormonal phase, energy levels, or life stage. Best for: women who want comprehensive food logging and don't need cycle-based adaptation.
Atunelle — cycle-synced fitness and nutrition
Atunelle connects the areas the other apps handle separately. It tracks cycle phases across four phases (and adapts when life stage changes that picture), runs a personalised Nutrition Blueprint with transparent BMR/TDEE and macro targets, recommends specific foods based on current phase, generates workout programmes that adjust by phase and life stage, and turns daily check-ins into food and activity recommendations.
On Pro, food logs via text, voice, photo, or barcode. Gentle sessions (walk, stretch, yoga, breathwork, and more) need no full programme. Perimenopause and menopause modes include vasomotor symptom tracking. Six life stages: natural cycle, birth control, pregnancy, postpartum, perimenopause, and menopause. Best for: women who want one app that adapts to their whole body — week by week, phase by phase, life stage by life stage.

Pricing compared
All four apps have free tiers with meaningful limitations. Paid plans are broadly similar in cost at the monthly rate — between $10–$13/month. Atunelle Pro is $12.99/month or $89.99/year — and the Pro trial requires no credit card.
Atunelle's free plan includes cycle and hormonal insights, shareable affirmations and quotes, check-ins, symptom logging, one food recommendation per cycle, and a limited Nutrition Blueprint — but no meal logging or macro tracking. The 7-day trial unlocks nearly all Pro features with 5 photo scans during the trial. Pro adds unlimited scans, full Blueprint detail, full food carousel, statistics, and everything else.
Which app should you choose?
Choose Flo if…
Your primary need is accurate period and ovulation prediction. Flo is well-established, has a large user community, and its health insights are improving with AI. If you already use a separate fitness app and just want reliable cycle tracking, Flo is a solid choice.
Choose Clue if…
You value scientific rigour and a minimal interface over social features and extras. Clue's research partnerships and algorithmic transparency are meaningful if data accuracy is your top priority.
Choose MyFitnessPal if…
Your primary goal is comprehensive food logging — especially if you eat a wide variety of foods and need a huge database. If you're not interested in cycle-based adaptation and already have a workout routine, MyFitnessPal's food database and integrations are hard to beat.
Choose Atunelle if…
You want one app that adapts to your whole body — not just your period. Atunelle fits if you want check-ins that change today's food and activity suggestions, workouts that respect cycle phase and life stage, a Nutrition Blueprint built from your measurements, menopause symptom tracking alongside movement and nutrition, and gentle recovery sessions on low-energy days — without juggling four separate apps.
