Logging or changing a weight
Open Log, type your weight on the keypad and tap Log. To change it, tap “Change today's weight”. To log or change another day this week, tap that day in the row of circles above the keypad. Weightmark keeps one weigh-in per day.
Editing or deleting a weigh-in
Open History and tap the entry to edit or delete it. A day you missed this week shows “No weigh-in” with an Add button.
Understanding Stats
Choose Week or Month. The graph needs at least two weigh-ins in that period; days with no weigh-in show as a dotted line. Your goal and BMI appear below. BMI uses your height and latest weight; it is general screening information, not a diagnosis.
Units, mode and theme
Tap the round profile button at the top right. Weight and height units are separate settings. Mode is Light, Dark or System; Theme is Minimal, or Vibrant in mint, lilac, sky or orange. Tap Save.
Missing data
Your weigh-ins are stored only on your iPhone; there is no account or cloud copy. Avoid deleting and reinstalling the app while troubleshooting missing history, and restore from your iPhone backup if needed.
Reporting a problem
Include your iPhone model, iOS version, Weightmark version, and the steps that cause the problem. Remove personal details from screenshots. Never send passwords or verification codes.
