The rule that finally stuck.

The first line of the second prompt is the one that earned this post.

Why do we keep getting lineheight font cut off issues

We checked the history: five times. The PR celebration title, the onboarding hero, the lift page headline, and now the Progress screen’s title — each one a different screen, each one fixed in isolation, each one fixed by bumping a number until the screenshot looked right. The lesson never made it back to anywhere durable.

So this iteration we made the rule load-bearing.

The bug class

React Native clips letters that extend below the line-height box. The web version’s designs use tight line-height ratios that look fine in a browser — browsers let letters hang below the box. The mobile port doesn’t get that. Port the ratio verbatim and the bottom of every “g”, “j”, “p”, “q”, and “y” gets sliced.

The fix is always the same: use a line height at least 14% taller than the font size for any large display text. The reason it kept biting us: test fixtures tend to use words without descenders (“Squat.”, “Bench.”), and the clipping is subtle on a simulator. Physical Android is where it shows up clearly.

The build check

A new check in the build gauntlet scans the app for any large display text where the line height is too tight relative to the font size. Any commit that introduces the pattern fails the build, with a message explaining the ratio rule. Digit-only displays — the rest timer, the goal stepper, the PR number — can opt out with a short comment since numbers don’t have descenders.

The check found an unreported clipping on the rest-phase headline that appears during a PR set. The headline has always had an undetected clipped bottom on “Stronger.” Never reported. The audit found it. That’s the kind of bug the gate exists for.

Five clipping fixes shipped together across different screens. One new build gate. The next port of a large-text design won’t need to discover this the hard way.

The duplicate CTA

The other half of the iteration was simpler. The home screen had two ways to get to the full session view: the main Begin/Resume button, and a smaller “SEE FULL SESSION →” chip below it. Both did the exact same thing. Dropped the chip. Nobody will miss it.

While the layout was open we moved the “SEE PROGRESS →” chip up to sit directly under the three training stats — the user’s exact phrasing was “right under the three metrics.” The link now reads as a hop off the stats, not as a footer.

What stays in the margins

Three Discord asks, three ships, one new build check, one unreported bug caught by the check, and one rule that finally lives somewhere durable. The next loop won’t have to relearn this one.
