RosaCue
A rosacea diary that shows you what your own logs actually say.
Everything you record stays on your phone.
The five levels you log against, from calm to severe.
Three steps, and none of them leave the phone.
Log your day
Skin severity on a five-level scale, plus symptoms, suspected triggers, sleep, exercise and products. Takes under a minute.
After 14 days, patterns appear
The app compares the days after each logged trigger against your other days — on the device, using your data only.
Read it in plain language
Optionally get a finding restated in two or three calm sentences.
Findings arrive with their own counter-evidence attached.
Counter-evidence is always shown
If a pattern held on 5 of 9 occasions, the card says so. Findings are never presented as settled.
Sample size is always visible
You always see how many observations a finding rests on, and nothing is shown before there is enough data to support it.
No product recommendations, ever
The app tells you what your log says. It does not sell you a routine.
There is no account, and nothing to sync.
Entries, notes and photos are stored only on your device.
No account, no email, no advertising identifier.
Photos never leave the phone and are not added to your camera roll.
The optional explanation feature sends only derived numbers — never your logs, notes or photos.
RosaCue is not a medical device. It does not diagnose, treat or prevent any condition. Patterns it shows are associations in your own log, not proof of cause. Decisions about treatment belong with a qualified clinician.
