### 3/5 — Программа хорошая, но

*2024-12-20*

Программа по сути хорошая, но из-за челки на 15 айфоне трудно нажимать пару кнопок это смена вида станка и какая-то еще. Так как программа платная прошу вас поменять немного интерфейс, чтобы можно было полностью использовать приложение.

### 3/5 — Не удаляются файлы

*2023-01-26*

А ка файлы то удалять? Кнопка удаления не активна!

### 4/5 — Nice!

*2022-11-15*

I run Haas vf2s every day and it’s clearly the VMC this is modeled after. I have to say you did a great job. I have 2 huge complaints.

1) There seems to be no way to bring a file into the program from outside. This is terrible as the edit interface is clunky to use. (Which is very realistic)

2) You can set your tool diameter and length offsets in a realistic manner. You probably shouldn’t limit length and diameter as you have. Machinists in the wild are using tools you can’t imagine.

**Developer response:** Hello! Thanks for the feedback! I'm still working on size limits. Much depends on the limitations of the simulation algorithm. Application files are stored in the Documents directory. Perhaps you should try installing some kind of file manager.

### 4/5 — Awesome to practice

*2022-06-04*

Can you add a VPS? for doing quick jobs?

**Developer response:** Thank you! I'll think about it.

### 1/5 — Buggy, unfinished

*2025-11-27*

Has an annoying bug (not sure what’s causing it) where it basically breaks the whole game, offsets don’t work, manual stops working, doesn’t let you save…. Very annoying considering I paid money for this

### 1/5 — Useless

*2025-06-03*

The app does not allow you to copy paste code from outside or to open a txt file from inside the app. That means you have to manually write all the G code which makes this app useless. Waste of money, do not buy this. The Dev knows about it but they don’t do anything.

### 1/5 — Beware! no way to share a file with the app.

*2023-10-07*

The overall functionality is good, however there is absolutely no way of sharing a file with the app. This means that you have to type out ALL of the Gcode you want to simulate which is a complete non starter.

The developer replied to a similar review earlier and flat out lied saying the app has access to the Documents folders. THIS IS NOT THE CASE.

I thought that there would be some way of opening files in other locations, but there is absolutely no way of doing so. You can verify this by looking at the permissions the app is requesting and ‘Files and Folders’ access is NOT requested by the app . The funny thing is, you CAN save a file to another location, however for some inexplicable reason, there is no way to access other files from the loading page. I simply cannot understand this bone headed decision.

Till this gaping flaw is fixed, STAY AWAY and DO NOT BUY THIS APP.

### 1/5 — Crash

*2023-01-15*

Used to work until last update now just crashes constantly whenever i try to load blue print or open file

### 2/5 — Impossible de sauvegarder

*2026-01-27*

Bon jeu, mais impossible de sauvegarder son programme, crash au moment d’inscrire un nom

### 3/5 — Request to the dev

*2026-08-08*

Very good sim, but there is a need to add more tools like slot mill, and there is no option for a second round after the first round of operation on the workpeice. Small tools are not possible. Optional M01 Switch is missing. Thank you.

### 3/5 — Its not fully finished app

*2026-06-20*

App doesn’t allow you to copy paste or open the nc file from phone folder we need to write whole long program which consumes lot of time. If developer can improve this features then it would be worth of buying paid version or else for limited use no purpose.

### 3/5 — Много багов

*2026-01-10*

Баги относительно текстового редактора. После работы в нем остальные функции перестают работать, вплоть до вылета приложения

### 3/5 — Corrijam os bugs

*2025-06-28*

fecha sozinho, não permite colar códigos (até permite mas tem um segredo), arquivos somem depois de usar o aplicativo por alguns minutos, impossibilitando salvar ou carregar algum arquivo, seria muito melhor deixarem o teclado nativo do celular, para programar manual ou fazer alterações em programa gerado, fora isso, aplicativo excelente, melhorando o que é necessário seria nota 10.

### 3/5 — Не работает некоторый функционал

*2025-02-02*

Не работают настройки положения «камеры», зум. Нет возможности настроить расположение и масштаб «окошек». Челка айфона на экране очень не кстати.
Запускаю на макбуке - нет поддержки клавиатуры!
Разрешение экрана, размеры и расположение кнопок и окошек не настраиваются. Корректировать код рабочей программы надо одним пальцем, постоянно переключая с цифровой части на буквенную…
Набор рабочих инструментов, который можно использовать очень скудный.
Пожалуйста! Проведите оптимизацию!

### 5/5 — Great Simulator..

*2025-03-30*

This simulator is a great way to learn, or improve your knowledge of program reading/writing/understanding of G and M codes, macros, etc.

### 5/5 — Расточка

*2025-01-22*

У меня возник вопрос: есть ли в программе возможность работы с расточными фрезами? Если да, подскажите, пожалуйста, как их можно выбрать, чтобы я мог использовать их в своих проектах.

жду ответ в телеграмм @NeekChick

### 5/5 — Brilliant

*2024-09-24*

Very Clever Very Mindful Very Demure. Worth the download without a doubt

### 4/5 — Good for machinist starting out

*2025-05-29*

Everything that you can do on a mill with MDI commands you can almost do here! Really helps for people getting into machining like me to learn all i need about programming and G-codes and allowing you to experiment and visualize without potentially losing your job! But please update the app for the iphones with the dynamic island as it covers buttons and keys that i need to press having me constantly rotate the phone to access them. other than that i love it.

### 4/5 — 強制終了します。

*2025-02-10*

サブコードを使ったプログラムをデバッグすると
Message
Array index out of bounds, Index: 5, Array Length: 4 in gcode_parser.agc at line 872
というエラーが出て、アプリが強制終了します。

### 4/5 — 能不能更新中文

*2024-08-25*

更新更新

### 4/5 — G10 support please

*2024-03-10*

G10 support please

### 4/5 — .

*2023-02-05*

Program text is copied as a single line.
Can’t work with it.
If only typing it manually in the sim itself.

### 4/5 — Please Change the Keyboard

*2022-12-24*

I really like the app… the keyboard is a little bit annoying. Changing every time between numbers and letters disturbs the workflow.

### 4/5 — Great app but please other input options

*2022-12-18*

The app is very good so far. Easy to use and intuitive. Only entering from the actual program is tedious, because the UI keyboard is unusual. Switching from letters to numbers and vice versa is ineffective. Numbers and letters on a keyboard side would be appropriate or the use of a hardware keyboard.
