Why SkinLogs exists

"When did you first notice it?"

That was one of the first questions a doctor asked me, back in March. I had a few small patches on my skin, and I genuinely didn't know. I scrolled back through months of camera roll hoping a stray photo would tell me what my memory couldn't. Nothing did.

Without a clear timeline, I was given a cream to try for six weeks, mostly a guess, since nobody could say yet what this actually was. Six weeks later, the patches had grown and become far more visible. That's when I was referred to a specialist, and the wait for that appointment was another six weeks on top. By the time I was diagnosed with vitiligo in June, three months had passed with no real record of how fast any of it had actually changed.

Sitting across from the doctor, being asked many of the same questions again, I realized the whole visit would have gone differently with something as simple as a dated photo and a short note from day one. Not a diagnosis. Not an analysis. Just the facts, kept honestly, so I could actually answer the question instead of guessing.

That's the only reason SkinLogs exists. I built it to be the private diary I wish I'd had from the first patch: a place to note what I'm seeing, when I saw it, and what I'm trying, so the next time someone asks "when did this start," I have a real answer instead of a guess. If you've ever sat in an appointment trying to reconstruct a timeline that actually mattered, you already understand why.

The actual photo. Before I had a word for what I was looking at.

What you can do

See your skin clearly. Know what's actually working for you.

A quick photo, a routine you're testing, and a running history, all in one place, so you're never left wondering "was this always here?" or "is this actually helping?"

01

Snap a photo, keep it organized

A quick photo from the camera, or one uploaded from your library, gets saved privately to your device, organized by folder and date, and stays fully under your control.

  • Quick camera capture, or upload from your library
  • Saved privately, right on your device
  • Organized automatically by body location and date

02

See your history, not just one photo

Group scans of the same spot into a folder and log your own notes on a body diagram over time. A day streak and a few milestones on your Planner celebrate showing up consistently, a simple way to build the habit.

  • Daily check-ins feed a visual body overview
  • Attach a quick voice memo to any check-in
  • A Planner calendar shows every scan and reminder in one place

03

Routine Pattern Finder: see what's actually helping

Once you've logged enough Diary check-ins and Routine check-offs for an area, Routine Pattern Finder quietly compares your severity on days you used a specific product against days you didn't. No guessing which product is actually pulling its weight, just a plain comparison built entirely from your own history.

  • Tag a Routine product to the area it's for, then keep logging as usual
  • After 5 diary days, it compares your logged severity with it vs. without it
  • Every result labeled Early signal, Worth a look, or Consistent pattern
  • Runs entirely on your device, always a correlation, never a diagnosis

The problem we're actually solving

Memory isn't a record. SkinLogs is.

If you've ever sat in an appointment trying to reconstruct a timeline from memory, you already know why this matters.

Without a record

  • Scrolling your camera roll, hoping a photo happens to have the date you need
  • Guessing when something actually started
  • Trying to describe weeks of change from memory, in a ten-minute appointment
  • Starting over, every single visit

With SkinLogs

  • A dated photo, every time you check in
  • A short note on what you saw, right when you saw it
  • A real timeline you can actually show someone
  • Patterns you can see for yourself, not guess at

Skin conditions people track

A personal record for the skin you live in.

People use SkinLogs to keep their own dated photos, notes, and routine alongside the skin concerns they already know about, so a doctor visit has a clear history to look at.

SkinLogs doesn't identify a condition, name what a change might be, or tell you what it means. It records what you see and what you use, and you draw your own conclusions. For anything painful, bleeding, or changing quickly, see a healthcare professional.

A specific use case

Trying a new skincare product or treatment? Track it properly.

A new moisturizer, a retinol, a prescribed cream, sunscreen, anything you're testing out: SkinLogs gives you a dated, honest record instead of relying on memory for whether it's actually working for you.

01

Log what you're using

Add it to Routine with how often you use it and which area it's for. Check it off as you go, and flag anything that's not working, too greasy, stings, no change, so there's a record of it.

02

Note how your skin looks and feels

Daily Diary check-ins capture your own severity, itch, and trigger notes on a body overview, alongside a dated photo whenever you scan the area.

03

See if it's actually working for you

Routine Pattern Finder compares your logged severity on days you used it against days you didn't, for that exact area, and Compare puts two photos side by side, before and after. Always your own eyes, your own read of it.

More ways people use it

Not just for one thing

Tracking something while it heals

A cut, a bruise, a breakout calming down, skin recovering after a treatment: keep a dated photo record instead of trying to remember what it looked like last week. Compare puts two photos side by side, slider or overlay, so the change is something you can actually see.

More than one person, one device

Each profile keeps its own scans, folders, diary, and routine, fully separate from any other profile on the same device. Handy for tracking a kid's skin, a partner's, or anyone else's, alongside your own.
