### 5/5 — Very good!

*2019-11-24, version 2.0*

Very good app

### 1/5 — Мог бы поставил нулевой рейтинг

*2019-10-20*

Не рабочее глючащее приложение

**Developer response:** Отлично, а что именно не работает?

Чтобы приложение измеряло точно надо удостовериться в том, чтобы точки стояли в нужных местах, само приложение определят расстояние по фокусу камеры, то есть от точности фокусировки зависит точность измерения, я рекомендую ставить точки с расстояния 20-30см, так как чем дальше точка от камеры, тем менее точен результат, также необходимо обеспечить достаточное освещение, чтобы устройство фокусировалось быстрее и точнее.

### 5/5 — Красавчики

Очень точно! На 25 см, погрешность 0,6 мм

### 5/5 — Советую👍🏼
