Moya for contact dermatitis

Contact dermatitis tracker: what touched your skin, and when

A rash that showed up somewhere specific, after touching something specific, but not always on the same day. Moya is somewhere to log the exposure and the flare, so the gap between them stops being the hard part.

Quick answer

What is the best way to track contact dermatitis?

Log the flare and its exact location, and separately log anything new that touched your skin in the two or three days before, not just that morning. Many contact reactions are delayed rather than immediate, so the useful record is one with a few days of lead time built in, not a same-day diary.

About

What contact dermatitis is

Contact dermatitis is inflamed skin caused by something touching it, either through direct irritation or an allergic response. Irritant reactions tend to appear quickly, while allergic reactions are often delayed by a day or more, which is why patch testing is read across several days rather than on the day it is applied.

The method

What to record, and what it is for

What to log

  • Flare days, and exactly where on your body
  • New products, materials or substances touching your skin, by photo or barcode
  • Jewellery, gloves, cleaning products and anything work-related
  • Skincare and cosmetic changes
  • Sleep, stress and anything else going on that week
  • Weather, sweat and season changes
  • Anything new, which is where most surprises hide

What patterns are worth looking for

  • A flare that follows an exposure by a day or two, rather than the same day
  • Whether the flare sits exactly where a ring, watch, glove or collar touches
  • Whether a suspected product also turns up on your calm days
  • Whether avoiding a suspected item lines up with a calmer stretch afterward

What to take to an appointment

  • A timeline of exposures against flare dates, not just a list of suspects
  • Where on your body it appears, every time, named precisely
  • What you have already tried avoiding, and for how long
  • Photographs from a bad week, since that is rarely the day you are seen
  • The one question you most need answered
In the app

What a contact dermatitis tracker can and cannot show you

Moya does not present charts for you to interpret. Every so often it gently reflects back what you have been logging, in plain sentences, for example:

“Your flares have mostly appeared two to three days after a new product touched that skin.”

These are simply observations from your own entries, on your own terms. Moya is a wellness tool, not a medical device: it never diagnoses or gives medical advice, and a reflection is a conversation starter for you and your clinician, never a conclusion.

How Moya handles it

A photo diary that shows change

Skin changes slowly, and memory is unreliable. Progress photos stay organised and private, so you can compare honestly across weeks and months.

One short check-in a day

Under a minute, which is what makes logging a calm day realistic. The calm days are what the flare days get compared against.

Your entries do not leave your phone

Health notes are personal. Moya is built so the record stays yours, and there is no account for it to be attached to.

Questions

Questions people ask

What can I track with Moya for contact dermatitis?

Quick daily check-ins cover your skin, its exact location, and anything new touching it: products, materials, jewellery, work exposures. Everything is built for seconds-a-day logging.

Will Moya tell me what my skin is reacting to?

No. Moya is a wellness tool, not a medical device. It reflects back what you log in plain language so you arrive at appointments with a clearer picture. It does not diagnose, treat or identify allergens.

Why does the delay between contact and flare matter?

Many contact reactions are delayed-type, building over roughly one to three days rather than appearing straight away, which is why patch tests are read two and four days after application. A same-day diary misses the actual window worth reviewing.

How long before tracking shows me anything?

Often a handful of exposures logged against flare dates is enough to see whether something lines up, sometimes within a few weeks. A confident pattern usually needs several repeats, not one.

Is my skin data private?

Yes. Your entries and photos stay on your device. They are not uploaded to our servers or tied to an account, and you can export or delete everything at any time.

Can I use Moya as a contact dermatitis diary?

Yes, that is what it is. Daily entries and photos kept in one place, laid back out over time rather than scattered across a notes app and your camera roll.

Is there a free contact dermatitis app?

Moya is free to download, and keeping a daily record is free. Premium features are a subscription with a free trial, managed through your App Store account.

How much does Moya cost?
