Release notes

6.4.0

New features

• Apple Health Zones (iOS 27): choose "Apple Health Zones" in Settings and Form uses the exact heart rate zones your Apple Watch and Fitness app calculated for each workout, including any custom zones you've set.
• A clearer VO₂ max tile: it now shows units, a gray peer comparison (for example "Above average · 40–49 M") for ages 20–79, and "last updated" when your reading is over a month old. The tile hides when you have no reading yet.
• VO₂ max nudge: if Apple hasn't produced a VO₂ max reading in 30 days, Form suggests an outdoor walk, run or hike. It stays quiet if your cardio is indoors, swimming, rowing or similar, since Apple can't measure VO₂ max from those.

Improvements

• VO₂ max trend is steadier: it compares your recent readings with your earliest ones, and shows Rising, Holding steady or Declining. Holding steady is now neutral instead of green.
• The VO₂ max chart opens on 90 days, and a short explanation tells you why a reading may be out of date.

Bug fixes

• "Apple Zones" now matches Apple's own heart rate reserve bands, so Zone 2 lines up with what you see in the Fitness app.

6.3.5

Improvements

• Heart Rate Reserve (Karvonen) zones are now calibrated so Zone 2 is a true easy aerobic zone (40–55% of heart-rate reserve) and Zone 3–4 covers 55–75%. Previously Zone 2 sat at a much harder effort level. Your weekly targets are unchanged: 150 min Zone 2 and 45 min Zone 3–4.
• Workout summaries now show the heart-rate percentages for the zone model that workout was recorded under.

6.3.4

Bug fixes

• Fixed daily sleep totals sometimes showing noticeably less (or, rarely, way more) than what's in the Health app. Sleep is now tallied as one continuous night instead of being split or double-counted around midnight.

6.3.3

Bug fixes

• Fixed the subscription screen occasionally showing a free trial offer that wasn't actually available.

Improvements

• Your first 30 days are always free, with no charge until day 31.

6.3.2: Heart Rate Zone Model

New features

• Heart Rate Zone Model: under Settings → Heart Rate Zone Model, choose which formula computes your Zone 2 and Zone 3–4 training ranges. The options are Form Standard (the default, unchanged), Apple Zones (matches your Watch and Fitness app), and Heart Rate Reserve (Karvonen), which is anchored to your resting heart rate so your zones tighten as your fitness improves.
• Switching models updates this week's Zone 2 / Zone 3–4 progress right away; earlier weeks keep the ranges they were already computed with.

6.3.1: iPad support

New features

• Form now runs natively on iPad. In portrait, the dashboard splits into two columns (Today, Readiness, and This Week on the left; Nutrition and Trends on the right). In landscape, a left rail keeps Today and Readiness in view next to two scrolling columns for This Week, Nutrition, and Trends.

Bug fixes

• Fixed the Today card's mood icon getting clipped at the top of the screen in iPad landscape.

6.3

Bug fixes

• Fixed the Nutrition section sometimes staying hidden even when your data was ready to show.

Improvements

• A brief "fetching your data" screen now appears whenever you reopen the app, as well as the first time you connect, so you no longer see a flash of empty placeholder values.

6.2

New features

• Added notifications: a daily nudge, a recovery alert when you've fallen off pace, a Sunday recap you can share, and a check-in if you've been away for a while.

Improvements

• Background refresh keeps notifications working when the app isn't open.

6.0.1

New features

• Workout details now show Duration, Calories, and Average Heart Rate, plus a clearer Zone 2 / Zone 3-4 breakdown with color-coded labels.

Bug fixes

• Fixed the Sunday share button sometimes appearing but not doing anything when tapped.

6.0: Nutrition support

New features

• Daily protein, carb, and fat targets, calculated from your body data and whether today is a strength, cardio, or rest day.
• Set a nutrition goal (Lose Fat, Maintain, or Build Muscle) in Settings to get a personalized calorie target alongside your macros.
• If you log food in a third-party app (like MyFitnessPal or Cronometer) that syncs to Apple Health, the protein, carbs, and fat you've eaten show up next to your targets automatically. You never log anything inside Form.
• The Weight trend tile now shows how your recent trend compares to your goal (e.g. "On pace for fat loss"), based on the last two weeks of scale data.

Bug fixes

• Fixed onboarding's Privacy screen showing its three info cards at inconsistent widths.
• Fixed Nutrition sometimes staying switched off in Settings after reconnecting Apple Health.
• Fixed a nutrition number that could show slightly differently on two different screens.
• Fixed a nudge that told users to "connect a scale" even when they'd already connected one. It now asks for what's actually missing (height and birth date).

Improvements

• When Nutrition is missing Health permissions, the app now asks you to turn them on right in the Nutrition section instead of showing blank data.
• Onboarding now explains upfront what health data the Nutrition feature uses.

5.2

New features

• Added a Load Ratio (training strain) tile to the Readiness section, showing whether your recent training load is building up too fast.
• Added Vacation Mode, so your weekly targets and readiness scoring adjust automatically while you're away.

Bug fixes

• Load Ratio no longer shows a misleading spike after a break. It now waits for two weeks of training history before showing a number and displays "Building baseline" in the meantime.
• Fixed inconsistent spacing between tiles on the Home screen.
• Fixed the scrubbing tooltip landing in the wrong spot on some 7-day charts.

Improvements

• Refreshed tile icons and added icon + name headers to metric detail screens.
• Simplified the readiness and trend charts, with clearer 7-day/30-day/90-day views.
• Refreshed widget design with day numbers and mood icons.
