Ratings and reviews

Useful enough, but a little shonky. I downloaded this primarily to see the DPF regens on my Mazda Diesel which it does fine, but for some reason I keep getting notifications that are somewhat in Spanish (I think it's Spanish at least) and the MPG readings are Way off. Not sure how to fix these issues. Good features, but needs a little polishing still. If it were to be sorted 100% I'd gladly pay the one off fee for the full version. Not bad for a free app though!

Didn't have my 2009 Citroen Dispatch listed, so it required manually entering all the parameters. I got frustrated with that and gave up, to try again later when I had more time. I exited the app and closed everything. From then on, it kept opening itself in the background and bringing up notifications. No matter how many times I closed the app, It kept reopening. I even restarted my phone to no avail. Highly suspect activity. I don't trust this app doing its own thing. I have uninstalled it.

Though accurate on my old Seat Leon, Seat Cordoba and Ford Galaxy, the app does not work well with my new Dacia (Renault) Logan. It does not show the instant fuel consumption and the average consumption shows wrong values. It is impossible that the car takes 0,9 l/100 km, although I wish! After applying correction, the value switched to 14 l/100Km, which is impossible. I wrote to the developer three weeks ago. I did not get a reply.
