Meh

Lost connections with Vgate Pro constantly slow connection times.

No support

I was getting app support from Lee in the fall of 2025 and then he suddenly stopped responding to emails. I can only assume the app is no longer active. This is unfortunate as the app really seemed to be promising.

Great potential, no support

I really believed in the potential of this app. I was testing it and emailed support. Lee answered once and was very helpful but then I couldn’t get him to respond to the next three attempts to reach them. I’m left to believe the app is no longer supported.

Does not work obdlink cx

Not sure why it won’t connect to obdlink cx.

Once you OnTrack, you never go back!

Downloaded this over a year ago and have used it for more or less every drive since! Whether that be a road trip or a B road bash! So handy to keep an eye on temps and other valuable info which would usually be a pain to find! It’s all just there on your CarPlay screen! It’s a dream! Super easy to read important info at a glance and customisable to your hearts content!
Couldn’t go without it now!
Cheers Lee and all devs for listening to the users and implementing improvements almost instantly!
