By Then

A weight gain/loss calculator for people who have weight goals they want to achieve.
If you need to gain weight or lose weight, By Then will tell you what you need to do to achieve that goal. Simply enter your current weight and target weight, and then either a weekly weight change you can commit to or a target date, and By Then will calculate the rest.
The widgets allow you to perform the calculations right on your Home Screen for added convenience.
A one-off purchase unlocks the weekly weight-change projections view and a number of themes to personalise the app.
Simple, focused, to the point; you'll know where you need to be, By Then.
