I can only assume the app is no longer active. This is unfortunate as the app really seemed to be promising. ### 3/5 — Great potential, no support *2026-03-16* 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. ### 1/5 — Does not work obdlink cx *2025-12-01, version 1.3.17* Not sure why it won’t connect to obdlink cx. ### 5/5 — Once you OnTrack, you never go back! *2025-09-23, version 1.3.14* 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! ### 5/5 — Great for keeping an eye on things *2025-09-20, version 1.3.14* Always keep this on my screen to keep and eye on certain things like temps and voltage. The team behind the app are brilliant, always on hand to answer any questions, take feedback well and try to implement your thought into the app to make it a much better experience to use. I can’t go without it now! ### 5/5 — Great app with a super fast refresh rate *2025-09-20, version 1.3.14* Couldn’t be happier. Does exactly what I need it to do. ### 3/5 — Öltemperatur VW, AUDI, … geht leider immer noch nicht *2025-07-25* Eigentlich eine tolle App. Läuft bei mir stabil und die Meldungen beim überschreiten von selbst definierten Grenzwerten sind auch eine echt tolle Idee - der interessanteste Wert für mich ist die Öltemperatur. Der wird bei Fahrzeugen des VW Konzerns aber leider nicht ausgelesen. ### 1/5 — App crashes *2025-04-23, version 1.3.9* The app used be perfect. It was my go to OBD2 scanner and was always on my CarPlay. However, since IOS 18, the app crashes as soon as it connects to my OBD2 reader, rendering useless. This happens with or without a subscription. ### 4/5 — Carplay Support *2025-02-03, version 1.3.6* The application is handy, and I use it almost daily on my 2023 Subaru WRX, but I wish you could add gauges instead of numbers. It will be more appealing and useful, specifically with the Car portrait screen. I guess we have the right to ask since we are paying monthly fees ## Frequently asked questions about OnTrack ### What does the OnTrack - OBD2 Scanner app do?
