iPhone
Log a nappy change one-handed at 3am, glance at today's wet and dirty counts, and keep a rash diary you can show your paediatrician.
Every nappy change, logged in three taps — one-handed, at 3am, without waking anyone up.
Diaper Tracker is a diaper log and nothing else. No account, no community feed, no sleep coaching upsell, no feeding timers you never asked for. Open the app, tap the type of change, done. Today's wet and dirty counts sit at the top of the screen, so the "how many wet nappies?" question always has an answer — your own numbers, ready to glance at.
WHAT YOU GET
• Today's wet, dirty and total counts waiting at the top every time you open the app
• A full change log — wet, dirty, both or dry — with time, brand, size and a note, editable after the fact
• A rash diary: mark any change as mild or moderate and every rash entry lines up in one list, newest first
• A 14-day bar chart of changes per day, so the sleepless week blurs less and the pattern shows
• CSV export that opens in any spreadsheet — hand the actual log to your paediatrician or health visitor
• An optional reminder that tells you how long it has been since the last change you logged — after 1 to 12 hours, your choice
PERFECT FOR
• New parents counting wet nappies in the first weeks, tired of typing into a notes app
• Parents tracking a nappy rash who need dates and details at the next appointment, not memory
• Night-shift partners handing over one phone with today's record already on screen
• Anyone whose paediatrician asked "how many wet and dirty nappies a day?" and wants a real answer
WHY NOT JUST USE A BABY TRACKER?
All-in-one baby apps bury the nappy log under sleep, feeding, pumping, milestones and an account signup. At 3am, with your other hand holding a baby, you don't want a dashboard — you want one screen, one tap, one number. Diaper Tracker does the one job properly.
PRIVATE BY DEFAULT
Your log lives on your iPhone. No account, no cloud, no analytics on your baby. Export creates a file on your device and opens the iOS share sheet — nothing is uploaded anywhere. Diaper Tracker records what you enter; it never interprets your numbers and never gives medical advice.
FULL ACCESS
Diaper Tracker requires a purchase: a weekly or yearly subscription, or a one-time lifetime unlock. Full access includes unlimited change logging, today's counts, the 14-day chart, the rash diary, CSV export and reminders.
Log the next change in three taps — tomorrow morning the count is already there.
