With all that wasted space on the screen, why not give more room for the instructions. Ridiculous having to scroll to read more than two rows at a time. ### 1/5 — Does not work *2026-03-28, version 1.1.5* App does not work. It does not detect the upc that was entered. Waste of time. Just use youtube. ### 1/5 — Bad app *2026-03-27, version 1.1.5* Doesn’t work. Can’t even get past bar code. It needs the last 6 digits. Typed it in say not valid. Junk app ### 1/5 — This app is broken! *2026-03-23, version 1.1.5* It starts at the point they ask you to enter the last 6 digits of the upc code. Enter it in and it says “Unknown error” what’s the point of an app if it doesn’t work right? ### 1/5 — horrible app *2026-03-23, version 1.1.5* worked on android but not ios for some reason ### 1/5 — Total garbage *2026-03-21, version 1.1.5* This app is completely useless. I'm sitting here trying to log into the app by using the last six digits of the UPC and I got an unknown error. I can't even open the stupid thing let alone use it. Whoever designed this app should just find another job. ### 1/5 — Does not work *2026-03-21, version 1.1.5* 👎🏻👎🏻👎🏻 ### 1/5 — Don’t get the Bluetooth version *2026-03-11, version 1.1.5* Sucks. This is only useful if someone doesn’t know how to follow instructions on the regular one. Not that intuitive, disconnected often, and made me reenter all my info every time just to get the trigger to function. In the end didn’t make my ac colder either. That’s probably because of a compressor issue or something but that’s not why I gave it a poor rating. ### 1/5 — Physically doesn't work *2025-12-04, version 1.1.5* The app is fine, but the canister won't hook up to a vaccine set up if you're completely resetting the lines, has to hood directly onto the low side. Worst part is even when hooked up to the low side the readings are way off and the canister doesn't even pump into the A/C port, it just drips out of the squeeze grip. 0/10 waste of money ### 1/5 — UPC Not Exist *2025-07-27, version 1.1.5* App does not recognize the code, sad :( ### 4/5 — Works BUT *2025-07-20, version 1.1.5* Ok it worked but kept getting error pop up while I’m performing the tasks. It would also be nice if max pressure for the specific vehicle was given. I’ll use grok for that I guess. ### 1/5 — Who even asked for this? *2025-07-16, version 1.1.5* Inaccurate and cumbersome. Terrible idea. What’s wrong with a regular pressure gauge? ### 1/5 — Horrible instructions *2025-07-06, version 1.1.5* App is completely useless. Its only existence is to mine data from your location and gather an email account to spam you. Instructions were way off and completely useless. Check YT for better LP valve locations and usage. ### 1/5 — App is not functional *2025-06-25* I bought the Bluetooth “capable” r-134a kit and no matter which way I tried I could not get the app to use Bluetooth to connect. I tried every strategy, restart my phone, toggle on/off Bluetooth, reinstall the app multiple times… I never received the option to connect to the kit via Bluetooth. Therefore my purchase and this app are entirely useless and I will be returning it. I hate to say it, but in this case an old school gauge would’ve been more useful than modern day technology. ### 1/5 — Woof *2025-06-24, version 1.1.5* App asks you to enter upc, no matter what I enter it reads unknown error and I can’t proceed. ### 1/5 — Trash App *2025-06-23, version 1.1.5* The idea is genius the execution is remedial EPIC FAIL!!! ### 1/5 — Unuseable *2025-06-21, version 1.1.5* Didn’t have my truck listed. Waste of time ### 1/5 — Worst *2025-06-04, version 1.1.5* This is the worst app I have ever downloaded. Do not use this app , tried to upload the UPC code and it would not accept a valid code. Can’t even bypass the UPC screen if it doesn’t recognize the UPC code……… the worst app yet. I am returning their product and never buying again ## Most critical reviews (10 lowest-rated) ### 1/5 — Inaccurate gauge readings *2026-07-22* If you are downloading this app, you have already messed up. Return this product immediately and DO NOT use on your vehicle, the pressure will read incorrectly and in my Alice cause overcharging of the system. While it showed in all green on the app, not remotely close to the warning - it still managed to read inaccurately and over pressured. Stick to old fashioned gauges and return this product if you value your AC. ### 1/5 — Doesn’t work at all *2026-06-30, version 1.1.7* JSON errors when looking up vehicle. ### 1/5 — My Car Isn’t Included *2026-06-24, version 1.1.7* My 1969 Jaguar E-type isn’t included in the car lookup. ### 1/5 — Smart Gauge frozen *2026-06-03, version 1.1.7* The app locks up and Smart Gauge is not accessible. The app is sending JSON error messages connecting to my login. I never received the message to enter my UPC. Product is useless. ### 1/5 — App does not work *2026-06-01, version 1.1.7* App cannot load the files for any vehicle, it just displays an error, it’s unusable. ### 1/5 — This app is BS *2026-05-27, version 1.1.7* The app doesn’t even work. It’s hot as hell outside and all I’ve been trying to do is to get the damn app to even work. ### 1/5 — Junk *2026-05-27, version 1.1.7* Got error message every time I attempted to select my car model. I deleted the app. It’s useless. ### 1/5 — Asks too much information *2026-05-20, version 1.1.7* This is an app that just shows you videos and pictures for how to do something. Why do you need my location? Why are you asking for access to my photos? It makes no sense. Half the video didn’t load either. ### 1/5 — App said the recharge hose would fit my car, no hose they make fits it *2026-05-14, version 1.1.7* Garbage ### 1/5 — App wouldn’t work *2026-04-27, version 1.1.7* Tried the app a couple of times even uninstalled and reinstalled it. Would not let me make vehicle choice ## Most praised reviews (10 highest-rated) ### 5/5 — Ac pro *2025-08-19, version 1.1.5* Worked great on my 06 accord. App was helpful ### 5/5 — Bluetooth App Helpful *2025-04-27, version 1.1.5* Bluetooth App was helpful walking me through the step by step instructions (with pictures) for recharging the ac for my car make and model. ### 5/5 — Good info *2024-12-03, version 1.1.5* Very helpful. But it asks for too many permissions. ### 5/5 — Works! Good information! *2024-08-13, version 1.1.5* Works! Good information! A tiny bit of lag, but that might be my old /-\ss iPhone 6s+ I’m still running…. But my old /•\ss truck is blowing cold now! Thank you A/C PRO! ### 5/5 — Works like a charm *2024-07-17, version 1.1.5* Instructive step by step easy to use guide. Couldn’t be simpler. Great job! ### 5/5 — Great product for DIY *2024-07-11* Tried another refrigerant brand and didn’t have luck, but this brand was fast and simple. If you haven’t ever recharged the AC, make sure to read each step before trying to do it. And make sure to take the unscrew able tab from under the main nozzle. And then rescue the top back on. It’s easy to forget, especially if you do it in the dark. 05 4Runner ### 5/5 — Great app *2024-06-16, version 1.1.5* It’s a great app. Don’t trust the negative reviews; they’re left by literally dumb people. ### 5/5 — Awesome *2024-05-24, version 1.1.5* Pulled up my vehicle (02 Chevy Silverado 1500 wt) easily in app. Step by step with pictures and video. The initial pressure reading was low, so we did 15 second intervals, shaking as instructed. The pressure indicator fluctuated from low (white) into red. It took about 8 - 15 sec fills for the needle to inch towards the green. It stayed at 20 on the gauge until after the 8th trigger pull. It started into green finally and we could feel the AC was cool and getting colder. It was hot out and the truck had been driving and running for 30+ mins, so we went to almost mid green on the dial. Still refrigerant to spare in the canister, and AC is icy cold. We did have a free inspection done at Meineke first to make sure the system appeared to be functioning, clutch engaging, condenser turning on/off. As the refrigerant got closer to full, the condenser stayed on for longer. We now have perfectly cold AC in a 22 year old truck (new to us). $59.99 for the bottle compared to $250 quoted to fill at Meineke. App and product worked perfectly. Thank you:) ### 5/5 — Great product! *2023-09-11* Don’t know why this product/app is rated so low. It took me 10 minutes to refill the refrigerant in my Audi A4. The instructions were clear and easy to follow. Had I taken my car to a car shop, I would have payed $250 more … ### 5/5 — Simple *2023-08-31, version 1.1.5* Just a pic of the valve is all I needed. 👍🏼 Worked like a charm. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
