### 1/5 — Does not support hybrid Sienna

*2026-07-14*

Does not work with any hybrid Sienna made since 2021

### 5/5 — Lexus owner

*2026-07-04*

Our family has 2 CT200h’s and a UX250h. Second son heading off to college and we were looking grab another CT200h. Finally bought the Veepak and downloaded/paid for the app. 
Used it to scan/test a car we were looking at and it gave me the satisfaction needed to make the purchase. Trip back home with the car was a few hours drive and I left the app open on battery monitor to watch the stats. 
When we got home I scanned the rest of our cars to check/test out the batteries. Great tool for monitoring/maintenance of your hybrid batteries.

### 5/5 — Good

*2026-06-28*

I used it to find the problem and the app helped

### 3/5 — OBD reader connection

*2026-04-15, version 3.4.42*

Can developers make the app remember the OBD2 scanner? If the mobile phone is going out of range (eg. to pay for the fuel), it will not reconnect with the scanner, once back in range. It needs to be reconnected manually. This may be very useful for drivers!

### 1/5 — Useless

*2026-03-14, version 3.4.38*

Will not recognize my OBDLink MX+ adapter at all. Pretends the adapter doesn’t even exist.

### 1/5 — No connection

*2026-03-07, version 3.4.38*

Highly frustrating the app can find  the device but automatically fails to connect and it doesn’t help you can touch the setting in the device until it connects….moving on to another app

### 5/5 — Helped me check the voltages and resistance of my Camry Hybrid

*2025-12-15, version 3.4.37*

Great! It is free to look at the live voltages and resistances of individual modules in my Toyota Camry Hybrid HV battery. You can also pay $20 to get the other tests done as well. I used the Veepeak OBD 2 and it connected flawlessly on my iphone 14 plus.

### 1/5 — App crashes

*2025-10-29, version 3.4.37*

I have tried 20 times to do life expectancy test and every single time of 3rd step after 30 seconds the app closes automatically.

### 5/5 — Khalid

*2025-10-23, version 3.4.37*

Very good i used and work smoothly thank you

### 5/5 — Great/Cheap App

*2025-09-27, version 3.4.37*

I never write reviews this is my first time ever, but this app is great, granted it does have you get a obd2 scanner for your car but I mean everyone should have one, regardless the scanners are cheap and then to use the other services it’s only $13.99 so your paying less than $40 to diagnose your car compared to other scanners, it’s great now I know when my battery will die and then I can replace it, great app I definitely recommend the purchase of the scanner and service 👍
