SpotTrack - Spot & Skin Tracker
SpotTrack is a photo diary for your skin. You take or choose a photo of your face, tap to mark the spots you want to follow (dark spots, freckles, blemishes or marks), give each spot a name, and note what care you used, such as sunscreen, a spot cream or a serum. Over weeks and months the photos build into a record you can compare.
Changes in skin are slow and easy to misjudge in the mirror. Lighting, angle and memory all play tricks. Consistent photos taken with a face guide, kept in date order and viewable side by side or with a slider, make it much easier to see whether a mark is fading, staying the same or changing.
It is useful for people trying a new skincare routine, people following up on marks after a breakout or a cosmetic treatment, and anyone who wants a dated record to show a dermatologist.
The app runs entirely in your browser. What you enter is saved only on this device.
How to use SpotTrack
- Add a photo. Tap Add Photo on the home screen. Take a photo with your camera using the face guide, or choose an existing photo. If the browser can't use the camera, choose from your photos instead.
- Set the angle. Mark whether the photo shows the left side, the front or the right side of your face, so later comparisons use matching angles.
- Mark spots. Tap the photo where a spot is and link it to a registered spot or register a new one with a name. Long-press a mark to remove it.
- Add care and a memo. Record the care you used (sunscreen, spot cream, laser treatment, peeling, serum or other) and any notes, then save.
- Manage your spots. The Spots tab lists each named spot with the date it was first recorded and how many records it has. Open one to rename it, see its history or delete it.
- Compare. Tap to compare photos. Filter by angle, spot and period (one week up to three years) and switch between side-by-side and overlay views; the overlay uses a slider to wipe between the two photos.
- Check your progress. The home screen shows your total photos, photos this month and your latest records. The Records tab is a calendar: tap a day to see the photos taken on it.

Taking skin photos you can actually compare
Same light, same place
Lighting changes how pigment looks more than almost anything else. Warm indoor bulbs, overhead light and direct sun can make the same spot look darker or lighter. For a fair comparison, take photos in the same spot at about the same time of day, ideally facing a window with soft daylight, and turn off mixed artificial lights. Avoid flash, which flattens detail and creates glare.
Same angle and distance
Keep the camera at the same distance and height each time and line your face up with the guide. Recording whether the photo is from the left, front or right means you can compare like with like. A small change in angle can make a spot look larger or smaller than it is.
Bare skin and a regular rhythm
Photograph clean skin without makeup or tinted products, after the same routine each time. Weekly photos are usually enough: skin renews itself over several weeks, and most marks change gradually, so daily photos mostly show noise from lighting and redness.
Sun protection matters
Ultraviolet light is a major driver of dark spots and of their return after they fade. Dermatology organisations commonly advise using a broad-spectrum sunscreen every day, reapplying it when outdoors for long periods, and wearing a hat and seeking shade. Recording whether you used sunscreen alongside your photos can help you see how consistent you have really been.
Know when to see a dermatologist
Photos are useful for a doctor, but they are not a diagnosis. A common reminder for moles is the ABCDE checklist: Asymmetry, irregular Borders, uneven Colour, Diameter larger than about 6 mm, and Evolving size, shape or colour. Any spot that is new and unusual, changing, bleeding, itching or not healing should be checked by a doctor or dermatologist promptly. Don't wait for a photo record to build up if something worries you.
Frequently asked questions
Where are my photos stored?
Only in this browser on this device. Photos and records are kept in the browser's own storage and are never uploaded. There is no account. Clearing browser data or using a private window deletes them.
Can SpotTrack tell me what a spot is?
No. It does not analyse or diagnose anything. It only stores your photos, marks and notes. Ask a dermatologist about any spot you are unsure of.
Why can't I use the camera?
Your browser has to allow camera access, and some browsers or devices don't offer it to web pages. You can always choose an existing photo instead.
How many photos do I need to compare?
At least two. Once you have two or more photos, the home screen shows a comparison you can tap to open the full compare view.
Can I delete everything at once?
Yes. Settings has a Delete All Data option that removes your photos, spots and records from this browser after confirmation.
How is the web version different from the phone app?
Photos, marking and comparison work the same. The iPhone and Android apps can also send photo and sunscreen reminders; the web version sends no notifications.
Limitations of the web version
- No reminders on the web
- Camera capture depends on browser support
- No analysis or measurement of spots
- Photos stay in one browser and are not backed up
