Carista Bluetooth OBD2 gadget on sale for $14 on Amazon

I have recently switched to iPhone from Android (not because I think it's better, but because I came into a free iphone 5s and later 7). The OBD2 dongle I've been using before with my Android phone was great and worked all the time, but now that phone is relegated to the bedroom and I wanted to get an OBD2 adapter that worked with iPhone. I've had my eye on Carista and just now went to Amazon to buy something else (chain saw related) and there was Carista for $13.99. I pulled the trigger. Just wanted to let people know that have been on the fence. It's very good to have a basic OBD2 adapter. I never tried Carista, but I heard it works with iPhone and apps such as Torque, etc.

 

I seriously doubt that Carista gets to know when and to whom each adapter is sold. I am almost sure that the trial starts when you install the app. But, I don't know that for a fact, of course.

I know! I really struggled when I first switched from my beautiful, but aging OnePlus One? to the 5s. It drove me absolutely crazy! Part of it was the tiny screen and tinier yet targets in the interface. Also, no "back button"?!!! Insane! Why the $%^$ not?! it's the most useful button on a touch screen interface (kind of an "undo"). Yet, Apple, decided that each and every individual circumstance will have its own "back" button built in (or not, it's up to the developer, I guess) and it will be wherever the developer decides, not in the same place all the time. Insane! Also, I can not arrange the icons the way I want, iOS does it for me according to some plan (I think it may be alphabetic, but who knows). Also, I can not make an app a default for certain actions, like navigate. I do not care for apple native nav app and prefer Waze. Why can't I make Waze my default app?!!! Why do I need to copy an address from a text message and paste it into the Waze to use it?!!! Something I never ever had to wonder about on Android. I set it up the way I liked and "it just worked". Not so with Apple. If you want to do something even slightly different than the curators of the Walled Garden intended, you are SOL.

Also, my 2014 OnePlus One? had 64GB of memory, a huge screen (much bigger than 7), was super slim and comfortable and cost $300 new! 5s cost $650 new and has 16GB of memory, has tiny screen.

Now that I am off the 5s, I must say the 7 is much better for me. The interface targets are easier to hit with my finger and the whole phone is way more responsive than the 5s was. 5s was not being updated to V13x iOS, while 7 is running the latest. I must say that I do love the camera on both phones. Also, the all metal case made from a single billet is great (too bad they did away with that in later models) as it really does hold up to use. So while I am enjoying the free iPhones (cast offs from my extended family members), I would never ever spend money on one. They are crazy expensive and after owning and using one for a while I honestly do not understand why. But I'll take one or more for free. Actually, my 7 was not entirely free. It came with a broken screen, but was less than a year old (teenager owned it and dropped it in summer camp). Since I got it for free, I splurged on a genuine Apple repair for the screen, which was $150 at an Apple store. Apple store was another experience that I have not had before. Wow! the cool aid is strong! but they fixed the phone within an hour while I relaxed on a mall bench.

Now to find out if the Carista thing will work as advertized... I hope so, as I am tired of dragging my bedroom OnePlus to do OBD2 things on cars.
