Lishtot 4+

I have a X running 11.4.1. Couple of things need to be fixed. The version in the App Store crashes and closes after approximately 3 min of up time. In addition, the UI has the device hanging off of the main page where by making the S/N unreadable and the device un-selectable. There is also no way I have found with this version to delete history. Also, selecting the history makes the app crash out. I have uninstalled and reinstalled several times thinking 11.4.1 may be the issue. To no avail. Please fix. This would be great once the app/UI is useable. Oh. And the constant connect/disconnect with respect to the Bluetooth connectivity causes the app to crash and close as well.

A for technology. D for customer focus. It should have been clear that you don't have to contact the water. "No need to touch the water!"
Something like that on the outside of the box would have done wonders.
I expected to dunk the thing into a glass of water. From the reviews I've read, I'm not the only one who felt that way.
Let's face it; you name something TestDrop+; people are going to expect to drop it into the water.. it being a water tester and all.
It works from my tests, but I can't see how reviews will trend to positive because the entire explanation of the process is confusing.

I spent $20 on the device and after fiddling with this app for 15 minutes, I got it to work to say my water was a score of 100. That’s it! No other info about all the stuff listed on the side of the box. What an absolute waste… say no to this device and this app!!
