What's New in PD Meter

1.0.37

November 7, 2026

• When you mark the card, PD Meter now checks the second card end as soon as you place it. If it sits on the first mark, or is too short or too wide to be the card's long edge, it isn't placed: you're shown what to fix and a dotted circle where the other end probably is. Two marks on the same eye are picked up the same way. • After "Measure 2 more times", Your PD, Share and Saved People use the middle value of your 3 reads. If one read is a long way from the others, you can re-measure just that one.

Doesn’t work well

When you try to adjust the position of the measuring points the whole picture moves. So it is impossible to adjust the measuring points.

Response from developer

Thanks for reporting this. After all four points are placed, they lock so a stray touch can't move them. To adjust one, tap "Adjust points" under the photo, then press directly on the marker and drag. The magnifier shows exactly where it will land. A touch that starts away from a marker scrolls the page instead, which is likely what moved the picture. We're looking at making this easier to grab.

Não funciona

Como posso alinhar o medidor com minhas pupilas se a página fica deslizando? Um clique ativa o scroll e fica impossível usar o app

Falta também um melhor guia pra foto com cartão

Response from developer

Obrigado pelo detalhe. Se um toque no ponto da pupila faz a página deslizar, isso impede a medição — vamos checar no iPhone. O cartão precisa aparecer de frente na foto, na mesma distância do rosto.
