No download, no new account

Clue is a standalone app with its own account. Luna opens inside Telegram β€” no install, no extra sign-up. If you'd rather not manage another app and login, that's a real day-to-day difference.

Partner mode

Luna lets your partner follow your cycle and receive supportive, phase-aware tips in their own Telegram. Clue is built around the individual and doesn't offer a partner experience.

Price

Luna: free core tracking, 89-day Pro trial, then 99 Telegram Stars/month or 777/year. Clue offers a free tier and a paid Clue Plus subscription (typically several dollars a month). Luna is generally the more budget-friendly option.

Languages and regions

Luna ships in 17 languages including several CIS languages that big apps often underserve, with localized guide content for each. Clue supports many languages too, but coverage varies.

When Clue might be the better choice

Clue has a strong reputation for science-based content and works closely with researchers, and it's a clean, mature app. If a research-led editorial voice in a dedicated app is your priority, Clue is excellent. Luna optimises for convenience (no install), partnership, and price.

Frequently asked questions

What's a healthy cycle length?

Cycles between 21 and 35 days are healthy. Average is 28 days. What matters more than the exact number is consistency from month to month.

When should I track my cycle?

Daily, even if you only log the period start date. After 1-2 cycles, Luna's predictions become accurate. Adding mood, symptoms, and cervical mucus makes them sharper.

Is it safe to skip my period using birth control?

Yes, modern continuous birth control regimens are safe and supported by major medical bodies. The withdrawal bleed week was historical convention, not medical necessity.

Can stress mess up my cycle?

Yes. Chronic stress can delay ovulation, lengthen cycles, or stop periods (hypothalamic amenorrhea). Reducing stress + adequate calorie intake usually restores cycles.

How is Luna different from other trackers?

Luna runs entirely inside Telegram β€” no app to download. Predictions adapt to your actual data. Privacy-first: data never sold. Free for the first 89 days, then optional Pro.

When should I see a doctor about my cycle?

Cycles consistently shorter than 21 days or longer than 35, periods longer than 7 days, severe pain that disrupts daily life, bleeding between periods, or no period for 3+ months without pregnancy.
