What's New in Train531

1.5.0

August 16, 2026

EASIER TO READ, ESPECIALLY IN DAYLIGHT The app was tuned in dark mode, and the light appearance shipped without anyone checking it. Text carrying your weights, reps and units was well below a readable contrast level. Every screen has been remeasured in both appearances and fixed. LARGER TEXT NOW ACTUALLY WORKS Text size settings did nothing before, and turning them up made things worse, because icons grew while the words beside them stayed small. The whole app now scales properly, with layouts that reflow instead of truncating. JOKER SETS After an AMRAP that beats its target by two or more reps, you can add heavier low-rep sets above the prescription. Steps 5% of your training max, up to three. Offered only on a day the bar is flying, the way Wendler intended, and never on a day you ground it out. SEE YOUR FIRST CYCLE BEFORE YOU START Onboarding now shows the whole four weeks built from the numbers you just entered: your four days, your top sets, and how the percentages progress to the deload. It also says plainly that the program runs four days a week. COACHING THAT STARTS FROM YOUR NUMBERS The coach used to have nothing to go on for your very first workout. It now reads the balance between your lifts and works from it, so the first prescription is based on you rather than a dropdown. ALSO - Set type badges and controls now have visible edges instead of blending into the background - Charts are readable in dark mode - Assorted layout fixes on the workout screen and in onboarding
