Step 1
01
Log your skin
Rate breakouts, redness, and comfort each day. Attach a photo if you want.
Quick enough to keep up with, detailed enough to notice real changes.
Private skin tracker for iPhone, iPhone Duo and iPad
Know your routine. Understand your skin’s patterns.
Keep a searchable skin diary, reuse morning and evening routines, and review product ingredients. SkinLattice connects your own records into personal patterns, with your photos and logs stored on-device.

How it works
From daily check-in to personal ingredient pattern.
A calm daily rhythm: check in, connect what you used, then spot the ingredient patterns that feel personal to your skin.
Step 2
02
Track products and routines
Reuse a saved routine. Find products by name or barcode, read an ingredient label on-device, or enter details manually. Review ingredients before saving.
Your routine stays tied to the days that followed, not lost in a notes app.
Step 3
03
See your Ingredient Matrix
SkinLattice finds which ingredients seem linked to your calmer or rougher days — from your data, not generic scores.
Patterns stay grounded in your history, so the insights feel useful instead of generic.
SkinLattice 2.20
Clearer triggers, steadier routines.
Version 2.20 adds an avoid list, reaction timing, repeating routines, steadier skin photos, on-device summaries, and a trial timeline. It also brings two-column layouts on iPad and iPhone Duo.
Avoid list
Add single ingredients or groups such as fragrance and sulfates. Products that contain them are flagged, free for everyone.
Reaction timing (Pro)
See how long reactions usually take to appear after you use an ingredient, and which other factors were present on those days.
Repeating routines
Repeat a routine every few days or weeks, not only on set weekdays.
Steadier skin photos
A faint overlay of your last photo, an optional face guide and a light check help you take comparable photos.
Reports and summaries
Where Apple Intelligence is available, the weekly review, ingredient patterns and dermatologist PDF can include a short summary written on your device. Free users can export the dermatologist PDF for the last one or two weeks.
Trial timeline
Check the free-trial timeline before you start. An optional reminder arrives two days before the trial converts.
Features
Skincare tracking with a private Ingredient Matrix.
SkinLattice brings skin diary, product shelf, ingredient checker, and calm iOS-native insight into one privacy-first app.
Daily skin check-ins
Record breakouts, redness, and comfort, with optional photos and lifestyle context. Find past entries in your searchable journal.
Personal Ingredient Matrix
See which cosmetic ingredients may be associated with calmer or harder skin days, based on your own routine history.
Product shelf
Add products by name, barcode, label photo, or manual entry. Compare formulas and keep past ingredient lists connected to your history.
Privacy-first controls
Keep logs and photos on-device. Create password-protected encrypted backups, review what a restore will replace, or delete local data.
Reusable morning and evening routines
Save routine templates for your week, repeat a routine every few days or weeks, or reuse your latest morning or evening routine. Record what you actually used, including skipped sessions.
Reports for your dermatologist
Create a readable PDF of your recorded skin history. Free users can export the last one or two weeks, and Pro offers longer date ranges. Choose a paper format and whether to include up to six check-in photos.
Smarter skin signals
More than a skincare diary.
Review ingredient lists, recorded routines, and optional context together. The Matrix shows possible associations with evidence and confidence, including when information is limited or mixed.
Read the label
Ingredient-label reading on your device
Photograph an ingredient label or paste its text. On-device text recognition creates an editable list; check it against the packaging before saving. Manual entry is available when reading is unsupported.
Before you save
New product ingredient preview
Compare product formulas side by side. Pro product previews also connect a new product’s ingredients with your personal Matrix, while showing limited or mixed evidence.
Advanced context
Trials, weekly review, and routine context
Use 14-day product or ingredient diary windows, optional cycle context, and active-overload notices to review changes. These observations do not establish an allergy, a cause, or a treatment result.
Privacy
Your skin data stays yours.
The app is designed for sensitive personal data from the start, with local-first storage and clear controls.
- Photos are stored on-device unless you choose to back them up.
- Your skin journal is not sold to advertisers or data brokers.
- Optional weather context sends your approximate location to Apple WeatherKit. Turning it off clears the saved location.
- Create an encrypted backup, review a replacement preview before restoring, and delete local app data whenever you choose.
- Online product lookup sends a search query or barcode to external catalogs, without your saved journal, skin profile, or photos.
- Widget completion status is off by default. It never shows scores, notes, photos, or product names.
