Your goal weight now sets how much to eat
Set a target bodyweight (and, if you like, a date) and your daily calorie target now paces toward it — safely. It won't ever push a faster gain or loss than the evidence supports: if your date needs a faster change than is healthy for keeping muscle, the app paces at a safe maximum and tells you the goal will land a little later, rather than telling you to eat in a way that just adds fat. A far-off date keeps the gentle default pace. And if your goal weight points the opposite way from your training goal, the app keeps your usual pace and flags the mismatch instead of guessing. The calorie number is a starting estimate that keeps correcting itself from your weigh-ins.
Leaner, more honest muscle-gain targets
We corrected how fast the app aims to have you gain when you're building muscle. The old default pushed a faster weight gain than the evidence supports — and gaining faster mostly adds fat, not muscle. The default is now a deliberately conservative pace (slower for more experienced lifters, who add muscle more slowly), so your calorie target for a bulk comes down and more of what you gain is muscle. If you're cutting, the loss pace is unchanged. As always, your own weigh-in trend keeps correcting the target over time, and the reasoning is spelled out on The Science page with its sources.
Sharper numbers for machines, easy runs, and daily burn
Three calibration updates, each anchored to published measurements. Machine and isolation movements now use their own strength curve instead of borrowing the barbell one — people get more reps at a given percentage on machines, so suggested loads at moderate and higher reps rise a little toward the evidence; barbell lifts are unchanged. The easy-run heart-rate band is now deliberately wider, because where "easy" tops out genuinely differs from person to person — the talk test stays the boss, and the band says so. And your estimated daily burn now considers how long your sessions are, not just how many you plan: shorter-session plans estimate a little lower, longer ones a little higher, until your logged training takes over as the source of truth.
Polish everywhere: keyboards, thumbs, and honest numbers
A broad sweep of small things that add up. Escape now closes every pop-up, sheet, and menu — always as a cancel, never a confirm — and focus goes back where you were. Choice rows work with arrow keys, the landing demo's tabs work from the keyboard, and buttons across the app grew to comfortable thumb size. Numbers got honest: workout totals in your history no longer drift by a pound from the sets they sum, bodyweight entries show one consistent date and decimal everywhere (chart, list, and target alike), and session-rating stars visibly show the real rating. On Progress you can now tap any week in the training-frequency chart to see exactly which sessions it counts. Nutrition shows every macro you log — carbs and fat get their own trends once you've logged them — and a new “How these numbers are calculated” note explains each target in plain language, including where the estimate stops. Copy buttons only say “Copied” when the copy actually happened (and show you the text to grab yourself if it didn't), searching your exercises tells you when nothing matched instead of going blank, the feedback form links a short guide to writing a useful report, and the app tour now practices on clearly-labeled example data — including ticking off a set — without saving a thing.
