4★I really like the pro version, it's nice to have the export ability. One thing I would really like to add is the ability to have set points when driving in cold weather. I live in MN and notice that I can lose up to 50% of my range in the coldest temps. If there was a way to have an app shut off the heat when it reaches, say, 70 F and then turn on again when it drops down to around 62 F that would be great! I find I'm doing this manually to get more range but it seems like something an app could do.

3★A useful app for a Tesla owner. Still slow at times, but improved. STILL no tracking of phantom drain. I've been a pro subscriber from the beginning, but the updated pro pricing is almost 3 times what I've been paying so I'm not renewing. I was not really getting enough from the app to justify the old price, but was paying to support an app I want to stay around. I've adjusted my rating based on poor value for the updated pro price, and no phantom drain tracking. Still, it is a useful app.

4★Keeps signing me out at random. Infuriating. [EDIT] After updating the app version (as suggested by the devs) it seems better now. However, it still pushes me notifications that a drive is in progress even though I've disabled that specific notification. [EDIT2] Seems mostly good again now - friends not appearing anywhere (seems they've been de-added?) since logging in again...

3★I really like this app but it would be nice to see this project getting more updates. The bar graphs for instance need a rethink IMO. They were very confusing at first and even when I learned what info they are showing, I can't help but think a regular line graph would be easier to understand. I would also rethink the front page, I don't think VIN and software version are important enough to be the first thing you see. Also the ability to delete and maybe merge past trips.

3★I really like this app, but they removed the easy way to see quick statistics such as cost per km in electricity usage. I am considering unsubscribing because of that.
