Every change stays in the logbook
Each saved diaper change becomes part of the activity log. If inventory is set up, the entry also reduces the supply by one diaper.
Log a diaper change, check what remains, and see an estimate based on the last seven days of records. Inventory follows what you actually log.

Diaper Tracker connects two things you already record: diaper changes in the logbook and the number of diapers you have at home. It calculates an average from the last seven days of active records, then compares that with the remaining supply.

Each saved diaper change becomes part of the activity log. If inventory is set up, the entry also reduces the supply by one diaper.
The app reviews the last seven days and calculates the average using only days with at least one recorded diaper change.
The number of diapers you have is divided by your average use per active day, giving you a rough idea of how long the current supply may last.
Inventory and the logbook work together: enter a starting amount, record diaper changes, and the app calculates an average from your actual records.
Diaper Tracker keeps only the information the feature actually uses: diaper entries from the logbook, the current number of diapers in stock, the average across days with records, and the low-supply threshold. When you add a diaper record or a new pack, the view updates from those values.
The app totals diaper records from the last seven days and divides them only by the number of days that contain at least one recorded change.
When inventory is set, each new diaper record reduces it by one. The supply count changes together with the logbook.
At 10 remaining diapers or fewer, the app clearly shows a low-supply state. If notifications are enabled, it can also remind you to restock.
Adding +30, +50, +72, or your own amount increases the existing supply. If 12 diapers remain, adding a pack of 50 brings the total to 62.
Days remaining are an estimate based on current inventory and your saved entries. If records are less frequent or your baby’s routine changes, the estimate changes too.

Some days use more diapers and some use fewer. Diaper Tracker does not assume usage you did not record and does not set a changing schedule. The more real changes you record, the better the seven-day average reflects the usage the app can use for its estimate.
Enter a starting supply, add a pack of +30, +50, +72, or your own amount, then keep logging diaper changes. Baby Genesis shows the remaining stock and an estimate based on your records in one place.
