HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (2.1 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ Don't waste your time or money
★★★★★ I also highly recommend not purchasing the methanol kit until they can get lines that don't leak and fill the trunk up with deadly and expensive methanol.
★★★★★ For how much this device cost and then to have to pay extra money for the app and then it hardly works (1 year or use…) I'll be selling this crap tuner.

  • I'd happily have submitted this as a feature request but the support links in the app page just push you to the JB4 forums. 4★, Mar 18, 2023

Latest reviews, Japan App Store.

★★★★★Oct 2, 2026
A bit pricey

Got everything I needed in one place. Easy to use yet its UI is a bit clumsy especially in presenting the log charts. Was buggy with logging a while back (a glitch not being saved to “files”) probably resolved.

★★★★★Jul 1, 2026
Connectivity issues

Constant connectivity issues, and they clearly never update and debug.

★★★★★Mar 8, 2026
Wrong app for new bt adaptor

Wrong app get jb4 pro!

★★★★★Mar 5, 2026
Did not work

I couldn’t get it to connect. I cannot find any way to contact Support. The regular JB4 PRO app works fine wirelessly.

★★★★★Jan 31, 2026
Gauges freezing

I actually love the app and the capabilities are nice. You can do a lot. My problem is the app keeps freezing when u have the gauges open after doing a pull. I have to toggle to the maps menus and than back to gauges for them to show live feedback again. Maybe this is something I can change in settings??? If so would change to 4 star review

★★★★★Jan 12, 2026
Yes

App going to sleep fixed in the last update
