Buma baby journal, $1.9K in 30 days: shared family tracking

Where customers come from

Buma is available through the App Store and Google Play. Its blog covers infant sleep, feeding, and growth.

What stands out

Family members can view, create, and edit shared entries. Buma also counts forward from the last wake-up to show the baby’s next likely comfortable awake window and sharpens it after each logged nap.

Mum, dad, a grandparent, a nanny.

You log sleep, feeds, nappies, tummy time and anything else you invent — and both parents share one baby

Where it sits in the data

Buma's $1.9K in the last 30 days is higher than 82% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Health & Fitness” category (505 projects) it is higher than 89% (category median $96). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, the buyer would be a parent or caregiver who wants several family members to keep one shared record. Distribution would need to come through app-store discovery, content about infant sleep, feeding, and growth, and referrals within caregiving networks. The hard parts are building a dependable mobile product, handling family permissions, and supporting sensitive health and growth information.

Verdict: Needs real work.

One thing to take from it

Buma combines a shared family record with a single family subscription. Its product is organized around shared entries, custom trackers, and the daily details caregivers record for a baby.
