Weighback is a quiet companion for your weight tracking. It reads your existing weight readings from Apple Health, finds the meaningful goals based on your history, and presents them as a progressing staircase of milestones you can target. Treat weight loss like a rewind in time, for you to find your "weigh" back! NEW: MADE FOR IPHONE DUO • Open it up and your Stats & Goals sit beside your chart. • Prop it up like a laptop: your chart fills the top screen, with highlights and stats below and your goals in a drawer you pull up. WHAT YOU'LL SEE • Your all-time low. Every weighback goal you've crossed, in descending order. • Today's "weighback" — the most recent date you previously weighed what you weigh right now. (If the number on the scale feels familiar, it probably is.) • Your peak weight and how far you've come from it. • A chart that zooms cleanly from a single month out to your full history, with momentum panning when you grab the timeline. WHY IT'S DIFFERENT • Your data stays on your iPhone. Weighback never sends it anywhere, never logs in, and has no account. • It doesn't ask you to weigh in. It reads what's already in Apple Health, including readings from any scale or third-party app that writes there. • The full chart goes back as far as your data does. Weighback is free with no ads. A small in-app tip supports continued development; the feature set is the same either way.
