Version 1.4 — A summary you can trust. • Every number in the AI summary is now checked, on-device, against the data that produced it before you ever see it. If the model's summary doesn't pass, the app writes a plain, correct one instead — you never see an invented number. • Comparisons are honest: "in line with your usual range" is now judged against your own night-to-night variation, so a ten-minute difference is no longer breaking news. • Sleep numbers are right across midnight: "last night" counts the whole night, including the part before 12am. • VO₂ Max appears as a smoothed 8-week trend, so the summary talks about where your fitness is heading — not whichever reading happened to come last. • New in Fitness: your training mix over the last four weeks, and this week's training load against your own four-week norm. We removed the old ACWR risk score — the published evidence doesn't support it, so the app no longer pretends it does. • "What lifts your VO₂ Max?" — per-training-type estimates grounded in published research, shifting toward your own data as your training history grows. The card says plainly which of the two is speaking. • The summary speaks to you directly, in plain language, without lab units. • At a glance is reorganised into sleep, body, and training pairs, and shows this week's workouts against your usual rate instead of a six-month total. • Plus accuracy fixes throughout. Everything above runs on your iPhone — nothing about your health ever leaves it.

Version 1.3 — Clearer summaries. • The Insights summary is now formatted: headings, bold key numbers, and bullet points make Apple Intelligence's narrative easier to scan, instead of one block of plain text. Still generated entirely on-device. • Privacy update: this version adds anonymous, aggregate usage analytics (Firebase Analytics) so we can see which features people use — for example which tabs are opened and Progress-tab actions. It records counts and screen names only. Your health data and your Progress photos are never included and never leave your device. No advertising identifiers. See the updated privacy policy for details. • Various refinements and fixes.

Version 1.2 — Progress. • New Progress tab: take daily posed selfies (front / side / back) hands-free — one tap runs a spoken, countdown-paced photo burst through every pose, then auto-advances. No more juggling the phone and a timer. • Watch your body change over time as an on-device timelapse video. Each frame is automatically aligned on you using Vision body detection, so you stay locked in place across days even as framing drifts. Pick a playback speed from 0.25× to 4×. • Optional daily reminder so you never miss a capture. • Photos stay on your iPhone — saved only in the app's local storage, never uploaded, never synced to iCloud, never seen by us. • Everything else is unchanged: HealthKit stays read-only, the AI summary stays on-device, and we still run no servers.

Version 1.1 — iCloud sync. • Your iPhone reads HealthKit, processes it, and syncs to your private iCloud container so iPad sees the same charts and AI summary. • iPad and Mac no longer ask for HealthKit access — they're read-only viewers of the iPhone-processed data. • "Which zones are lifting your VO₂?" — clearer plain-language verdicts replacing the old correlation coefficients. • Privacy unchanged: we still run no servers, never see your data, and use only Apple frameworks (HealthKit, SwiftData, CloudKit, Foundation Models).
