Why 'no install' matters
Every extra app is friction: storage, another login, another icon, another thing to trust. Many people abandon period apps in the first weeks. Luna removes that hurdle β it opens inside Telegram, so starting (and sticking with it) is effortless.
Everything a tracker does, in a chat
Luna predicts your phases and fertile window, logs symptoms and mood, explains what's happening hormonally, sends gentle reminders, and offers a partner mode β all without leaving Telegram.
Great for low-storage phones and shared devices
Because there's nothing to install, Luna works well on full or older phones, and it's easy to open privately within a messenger you already have.
When a dedicated app might suit you
If you don't use Telegram, or you specifically prefer a standalone app with offline-first storage, a traditional app may suit you better. For everyone already in Telegram, Luna is the lowest-friction way to track.
