### 2/5 — Why though

*2025-11-10, version 1.3.20*

Why does it only allow two data channels and why does one of those have to be GPS Speed?

### 3/5 — Could be better

*2024-09-19, version 1.3.20*

Unfortunate that it doesn’t support editing the gate width… essentially making it impossible to review data collected from my Vbox Sport on karting circuits. Would be great if the app could be updated to include this and other features reviewers have mentioned

### 1/5 — Shocking

*2022-10-12, version 1.3.20*

Doesn’t load Vbox lite data. Application crashes, not intuitive. Poor effort, especially as the VBox costs ~£1500!

### 3/5 — Good App but missing potential

*2022-07-16*

The app is a tad bit buggy at times but it’s nothing major. What’s missing?

1. Ideal Lap feature/generator. This is a huge feature on the PC version. App version doesn’t cut up and blend the fastest sectors.
2. This needs a major makeover on the UI. Feels more like a “let’s shut them up and at least drop a little something” for the users that have been waiting on it.
3. Graphs should be more colorful and contrasty with bolder liners. Similar to “TrackTitan” software for sim-racers.

This app can really leverage the market but investing in UI enhancements for the app and Desktop version! Especially since sim racing is blowing up. This company is literally shooting themselves in the foot by not investing in revamping this app. Once revamped, it’s gonna spread like wildfire and boost sales for the VBOX Sim software on PC!!!! It’s free brand marketing left on the table by millions! Just saying!!!!!!!🤷🏾‍♂️

### 1/5 — No Lite support

*2022-04-26, version 1.3.20*

Poor show not playing lite files when they are effectively identical to HD ones.

### 1/5 — Not great

*2020-01-20, version 1.3.7*

Have to totally agree with the previous reviewer, I can get the app to load circuit data because the app doesn’t support video loading from Dropbox (and even if it did I would have to pay £98 for Dropbox plus) or I have to load the video files from an SD card, but where is the SD slot on an IOS device I ask you...correct there isn’t one, but you can buy a £45 device and stream the SD card to Your iPhone / IPad. So awful, why can’t the software use the built in calls in IOS to enable access to data stores; one drive, iCloud and ‘files’

### 2/5 — Could be so much better

*2019-11-10, version 1.3.7*

Tbh it’s really not good enough - and could be without too much difficulty

1. Accessing data is much too difficult. Why can’t I just load off a memory card that I plug directly into my iPad. Transferring to Dropbox (which then transfers it to the local storage on your iPad anyway) is a faff and not necessarily easy track side where data connections can be lacking. 
2. Won’t support video files from my current vbox setups in the race cars - other reviews and images suggest it maybe does for the HD Vbox 
3. Only allows 2 channels of data to be analysed/overlaid ... really 4 are needed at a minimum.

### 3/5 — Vbox lite

*2019-04-09, version 1.2.2*

Excellent app.  A bit mean it doesn’t play vbox lite video files....

### 1/5 — Does not work

*2016-09-24*

Every time I try to load a file from Dropbox, it crashes.

**Developer response:** Could you please send this file to us?
