### 5/5 — Lucid Support?

*2026-08-11, version 2026.32*

Any chance you will add support for Lucid vehicles? Thanks in advance.

### 3/5 — Lacking

*2026-07-29, version 2026.28*

Considering what they say in the app description I find the actual app very lacking, purchased premium yet very limited controls compared to other apps, no where to create automations although they state that. It’s more expensive than another popular 3rd party Tesla app yet seems to have half the functionality! It’s a shame as some of the stuff in the app like range rings are excellent and helpful! Visuals for battery information is great! Really let down by lacking the stuff they claim to have but actually don’t.

### 1/5 — Your website doesn’t work!

*2026-06-04, version 2026.21*

Your website doesn’t work! And now app have glitches

### 1/5 — Disappointed

*2026-05-03, version 2026.17*

I have waited over a week for this app to show me something other than what I already see with the Tesla app. The only consistent feature on this app is that it continues to disconnect from the car multiple times a day.

### 2/5 — Too obsessed with reporting and not basics

*2026-04-02, version 2026.13.1*

Used to be a useful tool but the developers are too obsessed with FSD and other reporting yet basics like home charging no longer works. The Add time of day charging has stopped functioning but nothing seems to be done about it. Very good on trip reporting but that’s about all value to me now.

### 1/5 — Phone Won’t Recognize Texan Pro

*2026-03-24, version 2026.7*

I installed TezLab and paid for 1 year subscription for TezLab Pro. Even though the purchase shows in my subscription list, the app does not recognize this purchase. Every time I click on an option in the app, it tells me I need to subscribe to Pro. I sent an email to support but have not received a response. Very disappointed. I’m hoping someone from TezLab reads this and contacts me.

### 5/5 — Incredible data

*2026-03-19, version 2026.7*

I can make .csv files and use them in python to make fun graphs of my car usage. This app is amazing. So much more from driving maps to weekly reports. It’s superior to the Tesla main app and I worked at Tesla.

Edit saved me 500$!

Was connected to a neighbors plug in duplex and they claimed way more usage and TezLab won when my data was presented to the landlord !

And I have years of data I can toss into an LLM and visualize for great sentimental value datasets

### 3/5 — Not as useful anymore.

*2026-03-16, version 2026.7*

well, as I said, not as useful anymore, and definitely not worth the price the app does more than half of what this app used to do

### 5/5 — Great statistical analysis

*2026-02-09, version 2026.1*

I really enjoy going through the data. It is very useful. I also like seeing the trips and especially the Range map which is really useful. You can set it for real world or rated.

### 1/5 — Deleted

*2025-11-29, version 2025.46.1*

UPDATE: I gave ONE STAR for this review yet users see all five stars..!!

I’d give ZERO stars for this app if I could. 

Can only sign up if you agree to tandcs AND receive emails from vendor. This kind of sign up is outwith Apples terms and conditions and has been reported. 

App should be removed from the store for this.
