Tried on my pc and same issue.

Saw someone else have the same problem. The app sign up system does not work for me. ### 1/5 — I wish I could log in! *2024-04-09, version 1.18.4* I downloaded the app before I was going to buy the tube port. As I have already had my car tuned from one of 034’s tuners. But when I tried to log in it won’t let me. I typed in the email they set all the confirmation stuff when my car was successfully tuned but I still can’t log in. ### 2/5 — Issue creating an account on app *2025-04-04, version 2.13* It keeps saying an email has been sent with further instructions but i haven't received anything even when i tried multiple emails. Please give me some help ### 3/5 — Everything looks good in theory *2024-03-13, version 1.18.2* Still waiting on live data update for mk5 2.0t, ea113. ### 3/5 — I wish I could use the app *2024-02-13, version 1.17* I’m unable to register on the app for some reason. ### 3/5 — DAZA support when? *2023-12-13, version 1.16* App is handy but half the reason I upgraded to the new dongle is for the in app gauges only to find out they don’t suppers the DAZA motors yet. Might wait for 8V RS3s. ### 4/5 — Works just fine *2025-11-16, version 2.15.3* Used it a few times, only issues I’ve had was with iPad battery too low or wifi not working. Interface is fine, customer service via app is meehhhh could be better. Via email, the guys got back to me within the day, tune logs came within 12hrs. I nagged them as I needed the a tcu file on a track day, they got it to me within 6hrs. ## Most praised reviews (9 highest-rated) ### 5/5 — Josh is the guy *2026-06-12, version 2.21* I was going through issues getting into the app because of my own mistake and Josh short for Joshua helped me out step by step. I can’t thank him enough for the help. Josh is that guy. ### 5/5 — App Review *2025-02-06, version 2.12* This App works great with flashing my Audi S5 on the fly between the different fuel maps. It’s also great with monitoring data going on with the car. Another great feature is checking engine codes and having the ability to clear them on the fly without needing a Scan tool. This app is super convenient and the main reason why I’m never switching tuners. I’m extremely satisfied customer. ### 5/5 — Great app easy to use! *2024-11-28, version 2.8.5* Easy to use once you are logged in also super useful and does great for my Audi B9 S4!! ### 5/5 — Works Great! Lots of cool features *2024-06-15, version 1.19.2* I had the older generation adapter and just upgraded. Setup was simple and there are a ton of new features built in. The data logging dashboard is pretty cool too! The only thing that would make this app even better would be Apple CarPlay support so you could see the dashboard on your car's screen. That would be amazing.. I hope the Dev team sees this! ### 5/5 — B9 S4 *2024-05-25, version 1.19.2* Apps great for data logging and more but i wish we got apple CarPlay support so we don’t have to open the phone ect. But beside that apps amazing ### 5/5 — Using this app and dongle on B9 S4 *2023-12-07* The application works flawlessly on my Audi it’s so convenient not to have to carry the laptop anymore for flashing. Awesome work 034 MS team. **Developer response:** We're glad you're enjoying the 034SPI app!
