iPhone Duo

The weight loss tracker built for iPhone Duo

Open iPhone Duo and WLTB spreads across both halves: your weight and your fast on one side, your trend and today's food on the other. Hold it like a book and the fold falls between them. Stand it like a laptop and your goal stays in view while the rest scrolls below.

Built for iPhone Duo in every pose, free and Pro alike.

Closed, your fast counts down on the outer display's Lock Screen.

Every tab

Two panes for every tab.

The Overview spreads its cards across the fold, and Charts, Logs and Settings split the same way across the inner display.

Folded, it's the app you know.

Closed, the outer display shows the Overview as you'd see it on any iPhone, with the tab bar down the side. Open it at any point and you carry on where you were, across both halves.

1

Every tab, two panes

The Overview and Charts lay their cards out around the fold, and Logs and Settings keep their list beside the page you're on.

2

Stood like a laptop

The upright half holds one card still, your goal's projection or your weight, while everything else scrolls below the fold.

3

Bars down the side

Where iPhone Duo moves the tab bar down the side, every action moves with it, so nothing sits on the fold.

See your finish line.

Set your goal, follow your trend and see how far you've come. Add calorie tracking, fasting and Apple Health when you need them.
