I’d rate it higher if I was able to either rearrange the gauges to display the ones I prefer without the need of scrolling away from other gauges. Or the ability to select which gauges you would prefer to monitor consistently. Also having the code reader function is nice and with each code a link to a video explanation is great, but the ability to clear the codes is missing. ### 1/5 — Meh *2026-07-01* It needs a lot of work. You cannot rearrange the gauges. You can’t resize the gauges. You can’t set individual alarms, such as fuel level. You can’t add gauges such as MPH or RPM. I’m glad that I supported him and purchased the app, but I will definitely be willing to spend more money for a better product. ### 1/5 — App works sometimes *2026-03-31* I just bought the app and a DA100 OBD sensor. I start the app, scan for the OBD port, and open the live gauges. I have an engine oil pressure alarm, and then no matter what I do I cannot get the live gauges to work. I was able to deformed shutdown the app, turn the ignition off, disconnect the sensor and then retry , I was able to get the live gauges to work once or twice but no luck. I read there is a bug in the app Any ideas when this will get corrected? ### 5/5 — Needs a login for app owners *2026-03-04* Purchased on iPhone and then had to purchase it again on Android head unit to van. Great app. It just cost me twice as much as expected. Having app on both devices has benefits though since you cannot see head unit under the hood. ### 5/5 — Peace of mind knowing the transmission temp *2025-12-16* Very cool app. Cool looking gauges. Transmission fluid temp is the main feature I use. ### 5/5 — Worth every penny *2025-11-16* This is a great app that does exactly what it claims to do. Works smoothly with the recommended dongle. V2 is significantly improved and your purchase price includes free lifetime upgrades. If you’re on the fence, buy this app, it’ll make you happ-eee. Seriously, it can provide the data you need to save thousands of dollars by warning you of engine temp, transmission temp, and voltage, in real time and on one screen. ### 5/5 — Future Feature? *2025-11-03* Love this app. One thing that would be cool in v3.0 if possible would be for the app to display on CarPlay/Android Audio. ### 5/5 — Confidence on Every Mountain Pass *2025-11-03* I use Kip’s app to monitor coolant and transmission temperatures while driving in the Colorado Rocky Mountains, which gives me peace of mind on those long climbs. Being able to see the exact transmission temperature is especially helpful during fluid changes, so I know precisely how much to add. Thanks, Kip! ### 5/5 — Version 2.0 significantly improves usability *2025-11-03* Purchased this app when first released. We have a 2019 pro master we use as a Food truck. This helps us keep an eye on things to notify of any issues we might be having. Worth every penny highly recommend the app to anyone with a Ram Promaster. ### 5/5 — If you own a promaster, buy this app *2025-10-05* Very good for V1 of the app, lots of usefully info. Needs to have the option to use Celsius though, as currently everything is in F. Would also love to have the app remember its bluetooth connection ## Frequently asked questions about ProMasters Only ### What is ProMasters Only?
