Does not support hybrid Sienna

Does not work with any hybrid Sienna made since 2021

Lexus owner

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.

Good

I used it to find the problem and the app helped

OBD reader connection

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!

Useless

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