Lamplit vs Clue
The Clue alternative for whole-body cycle tracking
Credit first: Clue is the strongest privacy citizen among the big cycle trackers — Berlin-based, top-scored in Mozilla's 2026 testing, with a public commitment to refuse data demands. If you want a dedicated, science-first cycle app, Clue is a genuinely good answer. This page is for people who want their cycle understood alongside sleep, training and mood — and a free core that stays free.

Why people look for a Clue alternative
Paywall creep is the loudest user complaint: long-term reviewers say the free tier has become 'basically just a slightly fancier calendar,' with subscription prompts 'after every action.'
The 2022 redesign still divides users — 'unintuitive' and 'clunky' remain recurring review themes.
Cycle-only by design: no sleep, training or nutrition context, no journaling — the Oura integration pulls temperature into predictions but never analyzes your cycle against training or sleep.
A policy promise, not an architecture: Clue's no-subpoena stance is admirable, but your data still lives on its servers, and hosting locations aren't published.

Where Lamplit takes a different approach
Private by architecture, on top of good intentions
Lamplit computes cycle predictions on your device, pauses them when your pattern is irregular rather than guessing, and makes cycle data structurally unshareable — no feed path, no partner codes. Clue's privacy record is genuinely strong; Lamplit's approach is to need less trust in the first place, with published EU hosting.
The cycle in whole-body context
Phase analysis beside sleep, training load and mood — and on Max, training coaching that weighs your cycle phase. This is the question a dedicated cycle app structurally can't answer: how your cycle, sleep and training interact.
A free core that stays free
Lamplit's Cycle Wheel, calendar and next-period prediction are free permanently, as policy. Pro adds import, extended predictions, phase analysis and perimenopause mode — but the core never thins out the way Clue's users say theirs did.
Where Clue genuinely wins
Trying to conceive? Clue Conceive is a clinically tested conception algorithm — Lamplit deliberately offers nothing comparable and makes no fertility claims. Clue also carries the deepest scientific credentials in the category, including a top rating in an American College of Obstetricians and Gynecologists journal study. For a dedicated cycle-science app, choose it without hesitation.
Who Clue is genuinely best for
- You're trying to conceive — Clue Conceive is clinically tested, and Lamplit makes no fertility claims
- You want a dedicated, science-first cycle app and nothing else
- Its Mozilla-vetted record and public no-subpoena stance are decisive for you
- You want the Oura temperature integration feeding predictions
Who Lamplit is best for
- You track sleep, training and mood — and want your cycle read in that context
- You want predictions computed on-device that pause instead of guessing
- You want core cycle tracking free, permanently
- You're in perimenopause and want whole-body data beside it
