So, I have been looking around for a way to disable the reverse beep and seat belt chime.
I found carista, but I'm in Canada and with our conversion rates, it's $26.
I find that extremely expensive to do just the 2 things I want.

So, I found this app called Prius tweak. It's for the 10+ Prius.
I emailed the creator and asked if he knew if it was possible for the app to work on the Ct200h.
He wasn't sure, but allowed me to test it out.
It's not able to do everything carista is able to do, as it only does the beep for reverse and the seat belts, but that's all I wanted.

Prius tweak is $1.82 on the Canadian Google Play.

Of course, like torque and carista, you will need a bluetooth obd2 dongle for the app to work.

Hope this helps someone else who doesn't need all the features carista provides, at lower cost.

That's pretty awesome that you can modify those things yourself. I will say though that I just asked my dealer and he did it for free when I was in for an oil change, so that seems easier to me.

From what I've read, the dealers seem to do a one time for free.
There are also stories on the forum of dealers charging $65 (US) for this service.

I also just got my car less than 3 weeks ago, so I'm a ways off before the car will be going in for an oil change.
The dealer is also an hour away from me.
Lastly, I plan on adding a few things to the car, which will require me to disconnect the battery, and if it's anything like my 06 Prius, the car will revert back to enabling these back to on.
So, I like being able to do it.

I'm just paranoid enough to not want to give any third party software access to my car's computer through the USB port. In all those news stories about cars being taken over and controlled remotely, it's my understanding that was only possible by first installing physically through the USB. Like installing on any computer, there can be unintentional tag-a-longs. I do want my backup beeps stopped, but will have dealer do it, hopefully free.

So if I get this app, I'll be able to get rid of the beep? Just wanted to confirm that it was available natively for the Android version.

Correct.
I have a Sony Xperia Z3 running Android.
You will also need a ELM327 Bluetooth adaptor for the OBD2, which you can get cheap on eBay.

These apps use a bluetooth or wifi dongle to allow the app to communicate over the OBD-II port. Once you remove the dongle, there's no way for any connection to the car to be made.

Right. I'd just be concerned about something in the background getting installed at the time it's connected, in the same vein as malware or viruses sneak onboard with valid apps on our computers.

:) OK thanks. Hope not!
lol

But on a serious note, I was actually surprised by how fast the app changes the settings. No waiting, done instantly.
When you go to use it on the car, you select connect to car:


Then, it pops up what devices your phone can connect to:


Then just tap on what you want to change.


It's changed right away.
No real transferring of information going across the devices.

Now, with my Subaru, I have a tune I've downloaded off the internet on the car, uploaded via a hand held tuner unit.
That is real information being uploaded to the ECU, and does take some time.

July 31 2018 worked! No more backup or seatbelt beeps purchased elm 327 obd2 Bluetooth dongle from eBay for $9.99. had to connect Bluetooth in the app, and then check all the boxes, and then uncheck all the boxes in order to get beeps to stop. took me awhile to figure out and I drove around the block while doing it with a passenger.
