No download, no new account
Clue is a standalone app with its own account. Luna opens inside Telegram — 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.
