A skincare log · Est. 2026

The skincare log for people who actually have a routine.

DewLog records your morning and evening routine, lets you photograph progress weekly, and shows you what's actually working — over weeks, not days.

What the app actually does.

Built for routines that take twelve minutes, not twelve seconds. No affiliate links, no upsells in the timeline, no "transformations." Just a record of what you used and what changed.

01 / 04

Log AM and PM routines — what you used, when.

Tap each step as you go. The app remembers your defaults so a typical morning logs in eleven seconds. Skip steps, swap products, or add notes like "stung a little around the nose."

A hand reaching for a glass dropper bottle on a marble vanity, half-shadow, mid-morning window light.
Three side-by-side portrait crops — cheekbone and jawline only — same neutral light, same head angle, labelled Week 0, Week 4, and Week 8.
02 / 04

Weekly progress photos — same light, same angle.

A camera overlay locks framing so this Sunday's portrait lines up with last Sunday's. Then four-up, eight-up, sixteen-up comparisons. The kind of side-by-side you can actually read.

Premium

Ingredient analysis — notice what correlates.

DewLog reads the back-of-bottle and tracks which actives are in your rotation each week. Over six weeks, it'll tell you something like: "On weeks you used niacinamide 5+ days, your redness photos rated 18% lower." No marketing claims, just your own data.

Macro of a single drop of clear serum spreading on a fingertip, soft peachy backdrop.
An open notebook on linen with a slim ballpoint pen, faint handwritten note reading 'stung — patch test next time' in soft daylight.
04 / 04

Reaction tracking — flag what stings.

A long-press on any step marks a reaction — burning, breakout, dryness, hives. DewLog cross-references the last 72 hours of products and ingredients and shows you the most likely suspects, ranked.

Eight weeks · One vanity

Pinned to the mirror, not lost in the camera roll.

The same crop, the same morning light, every Sunday. Side-by-side it's hard to lie to yourself — about what's working and what isn't.

Week 106 · 04
Week 206 · 11
Week 406 · 25
Week 807 · 23
This is what eight weeks on retinol might look like.
" DewLog isn't a shopping app. We don't sell products. We don't take affiliate commissions. We just log what you use, and notice patterns.

The vanity Q & A

Asked, answered.

The questions we get most often — about privacy, ingredients, and how the analysis actually works. Email start@djump.io if yours isn't here.

Yes. The camera reads barcodes on most products sold in the US, UK, Canada, Australia, Lithuania, and South Korea. If we don't recognize it, you can add the name and ingredient list manually, and it joins the catalog for everyone.
Premium parses the INCI list on each product and tracks which actives — niacinamide, retinol, beta-hydroxy acid, tranexamic acid, centella asiatica — are in your rotation each week. It doesn't make health claims. It just shows you which actives correlate with the weeks your photos rated better.
Progress photos live encrypted on your device by default and never leave it without an explicit export. If you turn on cloud backup (off by default), they're end-to-end encrypted with a key only you hold. We can't see them, and neither can anyone we work with.
Yes — daily logging and a 7-day history are free, forever. Premium ($3.99/mo) adds unlimited history, weekly photo comparison, and ingredient analysis. We make all of our money there. There are no ads, no affiliate links, no sponsored products in your timeline.
No. DewLog doesn't suggest products to buy, doesn't take affiliate commissions, and doesn't sell your routine data to brands. We'll tell you which actives in your shelf seem to correlate with better skin — what you do with that is up to you.
It works for whatever routine you have. Two steps or twelve, hydrating-only or acid-heavy, ferments or fragrance-free — DewLog logs what you use and looks for patterns. We don't have an opinion on the routine. We just record it.
