Days 1 – 5
Menstrual
The reset. Energy is low, the body sheds. MiraCycle dials back reminders and helps you honour rest.
Period · Fertility · Wellness
Your cycle, beautifully understood.
An intelligent tracker that learns from your real data — with dedicated planning for trying to conceive and IVF cycles, fully offline, in your language.
How it works
Three calm steps. The rest just happens.
No long setup, no quizzes. Open the app, log a few things, and MiraCycle starts shaping itself around your body.
1
Tell us a little
A quick onboarding — cycle length, goals, recent period. Skip anything you don't know yet; MiraCycle fills the gaps over time.
2
Log what matters
One tap from the home screen logs flow, mood, symptoms, BBT or intimacy. The daily flow takes seconds — and the deep features are right there when you need them.
3
See your cycle clearly
The Smart Engine learns from real data. Predictions sharpen each cycle, patterns become visible — and you finally have a calm, honest picture of what your body is doing.

Know your phases
Four phases. One you, every cycle.
Your cycle isn't one event — it's a quiet rhythm of four phases, each shaping how you feel, sleep, eat and move.
Days 6 – 13
Follicular
Estrogen rises, energy lifts. A great window for new projects, social plans and harder training.
Day 14
Ovulation
Peak fertility, peak clarity. MiraCycle highlights the window so you can plan — for or against — with confidence.
Days 15 – 28
Luteal
Progesterone calms but PMS can creep in. Honour rest, magnesium and complex carbs — your body knows what it needs.
Everything in one calm place
Designed around how your body actually works
Six pillars, one app — built so the daily flow is fast, and the deep features are there when you need them.
Effortless tracking
Flow, mood, symptoms, BBT, cervical mucus, intimacy — log a day in seconds, or in a single tap from the home screen.
Predictions that learn
An adaptive engine that gets sharper every cycle — confidence bands, fertile window, ovulation day, next period.
Trying to conceive
A focused plan with cycle goals, fertile-window highlights, BBT charting and partner-friendly reminders.
IVF planning
Stimulation, retrieval, transfer and beta-hCG timeline — designed with the medical workflow in mind.
Symptom intelligence
Spot patterns across cycles — pain, headaches, sleep, mood — so you can talk to your doctor with data.
Private backup
Encrypted backup to your own Google Drive. Your data, your account, never on our servers.

- Adaptive cycle and luteal-phase length
- Fertile window with confidence bands
- Late-period awareness without anxiety
- Calm, explainable insights — never a black box

Honest answers, no fine print
Yes — daily period tracking, predictions, symptom logging and private backup are all free forever. Premium unlocks the deeper tools: TTC, IVF, advanced analytics and unlimited cycle history.
Completely. Your cycle data lives in an encrypted local database on your phone. The only time MiraCycle uses the network is to back up to your own Google Drive — at your request.
On your phone. Optional backups go to your personal Google Drive, encrypted, under your account. We never store your cycle data on our servers. We don't even have servers for cycle data.
No. Not now, not later. There are no ads, no third-party analytics, no trackers. Selling cycle data is the opposite of what MiraCycle is for.
The Smart Engine learns from your real cycle history — and the more you log, the more it tunes itself to you. We show confidence bands rather than false certainty: when the model isn't sure, MiraCycle says so.
No. MiraCycle helps you understand your cycle and plan around it, but it is not a contraceptive device and should not be relied on as one. For contraception, please speak with a healthcare professional.
English, Croatian, Serbian (Latin & Cyrillic), Bosnian, Montenegrin, Spanish, German, Italian and French — translated by humans, with the same depth across every locale.
An iOS version is on the roadmap. We're launching on Android first to nail the experience end-to-end, then bringing it to iPhone once the core is rock solid.
Built with care
Made by people who'd actually use it
MiraCycle is built quietly, locally, and in conversation with the people it's for — partners, parents, friends and clinicians. We're not a venture-funded engagement machine. We're trying to make one calm, honest tool you can rely on for years.
