Waste of money *2026-08-04* It wont pair with your car after it collects all your information. Waste of money. **Developer response:** Sorry to hear you’re having trouble! If the car won’t connect, there’s definitely a reason and we can help you sort it out. Please contact support@tezlabapp.com from the email address on your account and we’ll look into it and help you get up and running as quickly as possible. ### 1/5 — Connection issue *2026-06-16* I have TezLab and works fine. This one cannot connect to my Tesla account. Sort this out please **Developer response:** Sorry to hear you’re having trouble! We’d be happy to help determine what the situation is and get it solved but I’m afraid we cannot see account info via reviews. Please contact us at support@tezlabapp.com from your account email so we can help! We’d appreciate an updated review once we help you get it sorted out 😊 ### 3/5 — Original TezLab Founders Member *2026-08-13* Being a long time TezLab owner, this app has no incremental value. Great for those that need the battery feature only. Know those that want to buy a Tesla and check the battery, perfect for that! ### 3/5 — Simple but not fully accurate *2026-05-23* Service response good. Picked wrong kWh total for MY. Don’t know if I believe the reports it states on fleet numbers. Good for general info. **Developer response:** Hi there - In response to you letting us know that it picked the wrong “When New” capacity for your vehicle, we undertook a fleet wide review to catch any unintended misclassifications, and any vehicles that were put into an incorrect bucket have been corrected. You can also override the “When New” pack capacity from the main screen if you wish. We apologize for any inconvenience. If we can be of any further assistance, don’t hesitate to contact us at support@tezlabapp.com ### 3/5 — Funzt, aber… *2026-05-22* Die App funktioniert. Zeigt aber viel zu gute Werte. 99,9% SOH für ein Auto aus 2021 mit über 40000km? Kein LFP… **Developer response:** Hallo, bitte kontaktieren Sie support@tezlabapp.com, damit wir die Fahrzeugklassifizierung überprüfen und Ihnen weiterhelfen können. ### 4/5 — Unable To Connect But Fixed / Good Option *2026-07-09* Unable to connect but got support. ### 5/5 — Perfect *2026-08-06* New to Tesla, exactly what I was looking for. ### 5/5 — Very solid! *2026-07-08* Perfect. App is super clean and gives me (and more) battery info. I love the how I compare to fleet data. Highly recommend. ### 5/5 — Really Epic *2026-06-29* Just what I wanted. Was easy to connect and gave me the battery numbers. The trend info is really cool Great value. ### 5/5 — Great App *2026-06-08* Love it! Please add widgets though for home screen and lock screen. ## Most praised reviews (2 highest-rated) ### 5/5 — Great / simple *2026-06-03* Clearly the developers put a lot of time into this. Exactly what I was looking for. Would recommend. ### 5/5 — 😍😍😍 *2026-05-13* Love the UI, good job to the team at TezLab! Would really love it for the car UI in the app to reflect the one in my app and not the UI from the VIN --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
