Trendcurve in brief
Trendcurve is an app for iPhone and Android that turns the daily ups and downs of your scale into a smoothed weight trend. It shows the 7-day change and your progress towards your goal, and it explains why a single day's weight says little.
The trend method can be chosen: 7- or 14-day average, exponential or double exponential smoothing. The core features are free. Forecast with goal date, calorie budget from the trend and further analyses are part of Trendcurve Pro.
