Open the app, pick a date, type your weight in kg, and you're done. One entry per day - saving the same date again simply replaces it, and future dates aren't allowed. Three charts, one scrolling screen - Bar chart of your last 20 days, color-coded by range with the value on every bar - Trend line for the last 30 days with your average marked; tap any point to see that day's date and weight - Distribution circle covering every record you have, with a legend for each range Your records Entries are grouped by year. Tap one to edit it, swipe or long-press to delete it, or clear them all at once. Moving to a new phone Copy your whole history to the clipboard as text, then paste it into DaDa on the new device to restore it. Restoring replaces the data already there. No account, no sign-in, no server. Everything stays on your phone and the app works completely offline. Free, supported by a banner ad.
