### 2/5 — Keine Automatik

*2016-11-25*

Die automatische Kartenerkennung funktioniert nicht. Habe mehrere Karten (EC, Kreditkarte, Perso) getestet. Die manuelle Justierung ist zu umständlich. Deshalb nur 2 Sterne

### 1/5 — 不太懂要怎麼使用

*2016-09-17, version 1.4*

真的看不懂這app在幹嘛的.... 拍什麼東西出來的方塊都是8.6&5.4釐米，跟介紹中的功能頗有出入

### 1/5 — 欺騙的app

*2016-09-17, version 1.4*

完全錯的離譜！100mm距離對焦量測54mm顯示8.6mm

### 1/5 — Lol

*2016-09-15*

### 1/5 — Confusing

*2016-09-14*

The app doesn't make the 2nd rectangle to measure the 2nd item. It doesn't really detect the card as well. Very confusing. Good thing I got this for free.

### 1/5 — 設計有問題

*2016-09-14, version 1.4*

量出來的尺寸都是錯的

### 2/5 — Bonne idée, mais à améliorer nettement

*2016-09-14*

Apparemment ça marche, mais seulement en mode manuel : l'appli n'a pas détecté elle même la carte ni l'objet, il a fallu dimensionner les 2 à la main. Et, pour un objet petit, les dimensions affichées cachent le coin qu'on cherche à aligner !
Pour info, il faut ajouter un rectangle pour l'objet à mesurer (en touchant "+").
Bref, il faut améliorer tout ça :
- que l'appli détecte effectivement la carte et l'objet à mesurer ;
- qu'il n'y ait plus aucune manip manuelle à faire
(éventuellement éclairer la scène avec le flash pour augmenter le contraste et faciliter ainsi la détection des objets ?)
A suivre !

### 2/5 — iPhone 4s

*2016-09-13*

Не работает. Делаешь фотографию- иногда находит карту, иногда приходится указывать её вручную, иногда путает карту с объектом, а дальше - ничего. Как добавить измерения - не понятно. Сверху кнопка назад, боковое меню и больше ничего.

### 2/5 — Imprecisa

*2016-09-11, version 1.4*

Podría ser útil pero es tan imprecisa que se nada sirve. Borrada !!

### 1/5 — Nothing right!

*2016-10-22, version 1.3*

Useless !

### 1/5 — 詐騙集團

*2016-10-20, version 1.4*

明明寫免費（內購買）結果下載時就直接扣款了

### 1/5 — La peggior applicazione comprata

*2016-10-10, version 1.4*

Soldi sprecati non funziona e misura a caso peccato sarebbe stata utilissima 😢

### 1/5 — No funciona

*2016-09-20, version 1.4*

La primera medicion fue correcta pero despues marcaba para todo la misma medida

## Most praised reviews (10 highest-rated)

### 5/5 — Really useful app

*2023-05-03, version 2.2*

This app is awesome, using my card as a reference is can give me very accurate measurements for other items on the camera.

### 5/5 — Great App

*2021-01-31*

Simple and Very useful...accuracy is appropriate for how easy it is to use. Nice work.

### 5/5 — Very interesting idea!😄

*2016-09-15*

Although it is not working perfectly at the moment, I am giving it 5 stars for the innovative idea and hoping for the updates for improvement!

### 5/5 — Хорошо

*2016-09-14*

Хорошая программа, почти всегда показывает точные размеры, погрешность ок. 0,4 см

### 5/5 — Fort pratique !

*2016-09-14*

J'ai telecharge l'app pour voir, malgre des critiques a 1 etoile. La traduction francaise est mediocre mais j'ai assez vite compris qu'il fallait cliquer sur le "plus" une fois la reconnaissance automatique de ma carte magnetique, que j'avais placee pres d'un objet a mesurer. 
Tres facile d'utilisation, j'ai verifie la premiere mesure avec une regle, exact au millimetre. L'app fait ce qu'elle dit = 5 etoiles.

### 5/5 — Easy to use

*2016-09-09*

Pretty good results too.  Need to level your objects though.  If the app can support upright correction, then boom!

### 4/5 — Nice

*2016-09-14*

Useful

### 4/5 — Good idea

*2016-09-10*

It took many tries to figure out how to use this. Once you realize you need to push the plus sign to measure something, whether it's a box or line, after you've encircled the CC, it will work. If you are not directly over the object to be measured when taking the photo, boxes won't measure accurately. If you need a measurement without having a tape measure or ruler, it can be a great help, but I'd try to be on wifi if you could.

### 4/5 — Accurate, but used cellular data

*2016-09-08*

I tested this with a card other than a credit card and it is accurate. However, I tested it with wifi off to see if it is using the Internet and it did use 24 KB of data, which would only be enough data for a very low resolution picture to be sent. To gain trust of the users, you may not want to have the app use data. Users should be sure not to use any cards with personal info.

### 3/5 — Not handy

*2016-12-15*

Should be more useful if the app can automatically locate the card and attach the box(the given one).
