Doesn’t work well
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
Falta também um melhor guia pra foto com cartão

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.
