Unfortunately it stopped working and I tried everything to get it to work again. It just game a white screen and error codes. If the bugs can be fixed I’d be a customer again. **Developer response:** This means a lot — we’d love to earn you back. The white-screen/error issue you hit has been addressed in a recent update, so please grab the latest version. If anything still misbehaves, email support@mechai.app and we’ll jump on it. Thanks for giving us a real shot as a DIYer. — The MECH AI Team ### 1/5 — Bug *2026-04-19, version 1.2.0* All I got was white screen ### 1/5 — Junk *2026-04-08, version 1.2.0* This app uses just general lousy, unspecific responses. You’ll use up all of your messages before you get any kind of answer. You need total junk not worth the time. ### 1/5 — Useless! *2026-02-19, version 1.1.9* Can’t subscribe or even watch the adverts for free use as it just keeps buffering! Tried for over a week incase it was a bug, restarted many times and still no good 👎 ### 1/5 — Bad information *2025-12-28, version 1.1.7* I have trusted the mech ai part number twice and gotten the wrong part twice. I ended up taking the part off and pulled the number from it. Don’t waist your time with this app, ### 4/5 — so far is OK, hope they don’t get waste!! *2025-12-21, version 1.1.7* Great app do DIY folks , keep it up this simple way, don’t get lost ### 4/5 — App will not update to latest version *2025-10-04* The app has stopped working on my device because of IOS version. It is a nice app but I can’t afford to purchase a new iPad to be able to use it. Is this an apple problem ? **Developer response:** Thanks for the kind words, and sorry the newer version won’t install on your iPad’s iOS — that’s an Apple OS-requirement limit, not a fault on your end. Email support@mechai.app with your iPad model and iOS version and we’ll point you to the last compatible build and any options. — The MECH AI Team ### 1/5 — No wiring diagram for starter jeep Cherokee first time use MeCH pro ,,, not impressed… sham *2025-09-09* Garage Onil **Developer response:** Sorry the starter wiring diagram for your Jeep Cherokee wasn’t there on your first try — that’s a letdown, especially on Pro. Wiring coverage is something we’re actively expanding. Email support@mechai.app with the year and engine and we’ll prioritize it and help you in the meantime. — The MECH AI Team ## Most critical reviews (10 lowest-rated) ### 1/5 — 5 Free messages *2026-07-04* 5 free messages daily then you have to pay more corporate greed slop, messes up most of the common issues anyway absolutely trash. ### 1/5 — Dismal! *2026-06-29, version 1.3.10* Dismal failure unfortunately! I had high hopes for this app but even if signing up presents major issues then what other problems will emerge? Sorry but it’s a no from me. 😬 ### 1/5 — Shonky garbage *2026-06-22* This is the shonkiest app on the planet. It’s clunky. When you try and ask a question you immediately hit a paywall. Horrible ### 1/5 — ZERO stars *2026-06-04, version 1.3.0* Every suggestion or repair was wrong ### 1/5 — Worked good but… *2026-05-23, version 1.2.0* App works good when it works. Last month 90% of the time it says server error. Disappointing since I paid for the monthly subscription.

All I get when I open the app is a blank white screen ### 1/5 — Buggy, unusable. *2026-05-01, version 1.2.0* Good luck even typing without a server connection error popping up. In 2026 this is an abysmal failure. ### 1/5 — Server error *2026-04-28, version 1.2.0* Have been trying this for couple of weeks with same outcome - Server Error. Useless! ### 1/5 — Horrible *2026-04-20, version 1.2.0* This AI does not help diagnose or repair anything. It is absolutely trash. Used to of my five questions with no answers whatsoever jump don’t waste your time. ## Most praised reviews (10 highest-rated) ### 5/5 — Mech AI is truly a life changing app *2026-06-18* It really a helps the newer generation of techs that are just learning to diagnose a car properly based on the customers words and descriptions of symptoms, also it makes me feel more independent in my own work letting me attempt to figure out the underlying issue based on my own educated guess’s **Developer response:** Thank you so much for the 5-star review — it genuinely makes our day.

Don’t use it all the time but when I need it. Love the information. Watch out other shop management systems. This is a game changer and totally recommend. **Developer response:** Thank you!

Thanks for sharing it. — The MECH AI Team ### 5/5 — ASE master *2025-10-22* I’ve been a mechanic for about 32 years. I’m an AC master technician I have a master certified Chrysler technician. I’ve got certifications for Ford GM tire pro from Goodyear in Bridgetown. I am probably 180 certifications in automotive. This site has been a lifesaver for me. I opened my own mobile mechanic business about seven years ago and I have not really been able to afford or support all data or identity fix on a monthly fee because it’s just so expensive for being an independent person like I am so I haven’t had access to information like this website can give me has been a game changer from a technician that’s been doing it most of his life or a week warrior. That’s just replacing stuff in his garage. It’s gonna have the information you need to complete whatever task you’re trying to do. Thank you for reading my review. **Developer response:** Coming from a 32-year master tech running your own mobile business — this genuinely made our day. Thank you. We’ll keep earning that lifesaver status. — The MECH AI Team ### 5/5 — Super handy and ads are entertaining *2025-09-28* Can supplement or replace the Hanes shop manual for my Audi a3. Sometimes the instructions are for a slightly different model but I can usually figure it out. **Developer response:** Ha — glad the ads landed too! Standing in for a Haynes manual on your Audi A3 is high praise. Thanks for being with us. — The MECH AI Team --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
