CheckMole vs MiiSkin: Free ABCDE Check vs Mole Tracking
CheckMole and MiiSkin both help you keep an eye on your moles, but they emphasise different jobs. MiiSkin is a mole-tracking app built around photographing spots and comparing them over time, with free and premium tiers. CheckMole is a free web tool for screening a specific mole against the ABCDE criteria right now, plus mole-mapping guidance. Here is how they compare and when each makes sense.
Two different jobs: screening vs tracking
MiiSkin's core strength is longitudinal tracking - taking consistent photos of a mole and using side-by-side comparison to detect change over weeks and months. That directly targets the single most important melanoma signal: evolution.
CheckMole's core strength is instant screening - answering 'does this spot show worrying features today?' via the ABCDE rule, without a photo. Tracking answers 'has it changed?'; screening answers 'is it suspicious now?' Both questions matter.
Cost and access
MiiSkin offers a free tier with premium features behind a subscription. CheckMole's ABCDE checker is fully free, needs no download, and works in the browser.
If you want structured photo tracking with reminders and comparison tools, MiiSkin's premium is built for that. If you want a zero-cost, zero-signup read on a mole, the web checker delivers it immediately.
Privacy and photos
MiiSkin is photo-based by design, so your mole images are stored to enable comparison over time - inherent to how tracking works. CheckMole's checker uploads no images; you answer questions instead.
The choice is partly about comfort: tracking requires storing photos of your skin; criteria-based screening does not.
Accuracy and honest limits
Neither app diagnoses skin cancer. MiiSkin does not replace AI diagnosis; its value is helping you and your doctor see change clearly. CheckMole does not track images; its value is applying clinical criteria consistently in the moment.
Both are triage and monitoring aids. A biopsy remains the only way to diagnose melanoma, and any mole that is changing, bleeding, or looks unlike your others belongs in front of a dermatologist.
Which should you use?
Use MiiSkin if your priority is disciplined photo tracking of specific moles over time and you want reminders and comparison tooling. Use CheckMole if you want a free, instant ABCDE screen of a spot today with no download or upload - and free mole-mapping guidance to monitor changes yourself.
Many people pair a free criteria check for quick decisions with periodic photos for tracking. The constant across both: report change to a dermatologist promptly.
Screen any mole against the ABCDE criteria for free with our checker - then use our mole-mapping guide to track changes over time and see a dermatologist if anything evolves.
