Sounds great, but let’s get it razor‑sharp before we let users feel like they’re just scrolling. First, make sure every button’s hit target is exactly 44×44 px – no more, no less. Next, give the progress bar a subtle color gradient that shifts from a calm blue to a fiery red as the workout nears completion; that’s a quiet cue that they’re approaching a hard set. Also, add a micro‑animation on the “you’ve beaten yesterday’s record” badge—just a quick pulse, no flash. If you forget that, users will feel like the app is just a pretty box, not a coach. Keep the layout consistent, the typography in sync, and remember: a clean grid is a silent cheerleader.
