The best Clue alternatives
Clue is a well-respected tracker. People look elsewhere mostly because sharing and the Conceive and Perimenopause modes need Clue Plus, or because they want to use an app without an account.
In short: Good Clue alternatives in 2026 are Splash (free, no account, free partner sharing), Euki and drip (open source, local-only), Apple Health Cycle Tracking (iPhone) and Flo (large library). Clue keeps sharing, Conceive and Perimenopause modes in Clue Plus; Splash makes them free. Splash can import a Clue export on your phone. Reviewed 28 October 2026.

Questions about Clue alternatives
What is the best free alternative to Clue Plus?
Splash includes partner sharing and the Conceive, Pregnancy and Perimenopause modes free, with no paid tier and no account. Euki and drip are free and local-only if you want the most private option. Clue’s own free version remains available, with Clue Plus adding sharing and extra modes.
Is Clue better than Splash?
Neither is better for everyone. Clue has named clinician authors, a long research record and EU jurisdiction. Splash has no clinician reviewer yet, but includes sharing and every mode free and works without an account. Try both: Splash can import your Clue export, so you can keep your history.
How do I export my data from Clue?
In Clue, tap More, then Settings, then Download my data. Clue shows a password and emails a download link that works for 72 hours. Save the zip, unzip it with the password, and choose measurements.json in Splash. The file is read on your device and not uploaded.
