Weighback vs VitalCast

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! 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.

Your watch already knows your resting heart rate, your HRV and how you slept. What it cannot know is why. VitalCast asks you one question at the end of the day, in a single tap, and answers it the next morning. Tag today. Alcohol. A late meal. A hard workout. Travel. Work stress. Thirty tags, one tap each, from the Home Screen widget, your Apple Watch, Siri or the app. Custom tags for the things only you do. What helps, what hurts. After five days with the same tag, VitalCast compares the mornings that followed with all the others: heart rate variability, resting heart rate, sleep, sleep efficiency, deep sleep. In plain percentages, against your own nights only, with the honest answer "no clear difference" when that is what the data says. Your data, not proof of cause. Explained, every time. A tag on yesterday becomes context in this morning's read: "resting heart rate ran high, you noted alcohol." Every score in the app shows its arithmetic, and every claim links to the study behind it. On your wrist and your Lock Screen. Live Activities count down the caffeine you logged to a sleep-safe level, hold Rest Mode with an end button, and watch the overnight signals when they sit off your range, on the Lock Screen, in the Dynamic Island and in the Apple Watch Smart Stack. A caffeine-window complication joins readiness and sleep on the watch face. Ask, from anywhere. "Log alcohol in VitalCast." "When should I stop caffeine in VitalCast." "Ask my data in VitalCast." Nine Siri shortcuts, English and Spanish. Works with the watch you own. Readiness, sleep score, training load with heart-rate zones, daytime versus overnight HRV, heart-rate recovery, on any Apple Watch that writes to Health, and with Oura, Garmin, Whoop and Withings data that flows through it. Still the records app. Your labs, medications, conditions and allergies from every health system on one timeline, the same lab value charted across providers, and appointment prep from your own records. No account. No server. Nothing uploaded. Everything is computed on your iPhone. Deeper analysis on Apple's Private Cloud Compute is one switch, off until you turn it on, and every card says where it was worded. In English and Spanish. VitalCast Pro is an optional auto-renewing subscription, monthly or yearly, with a free trial. Payment is charged to your Apple Account when you confirm the purchase, and the subscription renews automatically unless you cancel at least 24 hours before the end of the current period.
