Track moles and skin changes with photos, measurements, and UV alerts. Learn what to watch for and compare over time. Freckle never sees your data.
When you take a follow-up photo, Freckle overlays the previous image at adjustable opacity so you can match the exact angle and distance. Consistent photos make real changes easier to spot.
Each tracked area holds a full history — a scrollable photo strip, size measurements against a reference coin, and a chart showing how each spot has changed over time. Log symptoms as they come up, replay the whole history as a timelapse, and keep notes, status tags, and reminders all in one place.
Pick any two photos of the same spot and compare them side by side, as an adjustable overlay, or with a swipe slider. Measurements are shown alongside so you can see how much a spot has grown or stayed the same.
Real-time UV forecasting shows today's peak hours and recommends SPF for your skin type — and a daily alert gives you a heads-up when UV climbs. Build a skin profile with Fitzpatrick typing, risk factors, and any sun-sensitizing medications, and Freckle tailors your check-in cadence to match.
Skin Check 101 is a five-minute guided lesson on what melanoma looks like — and it's always a tap away. Freckle teaches the methods clinicians use, in plain language, with cited sources. It helps you notice changes; it doesn't diagnose them.
Measure spots against a reference coin for real-world sizing. Compare any two photos side by side, as an overlay, or with a slider. Back up to Google Drive or export a PDF for your dermatologist.
Most apps in this category want your photos. Freckle doesn't. There's no Freckle server, no account, and no analytics watching what you do. Your data is yours — stored on your device and optionally backed up to your own Google Drive.
This is a deliberate choice — skin photography is personal. You should be the only one who has it.
