Amazing

I love how it tells speeds and best coverage for each type of phone in each area.

Great accurate tower locator

Awesome coverage indicator on finding out coverage and where the towers are. The most accurate app and website on the internet in my opinion

Good but add this

This is a good app. It would be great if we could see:
- what the past test on a map device was. This will also tell us which phone gets the best speeds on the specific cell provider.
- If you wanted to you could also add a best phone (per speed test) (not for the most test run but per that test. This will tell someone if a test was run with a 7 year old phone or one from 0-2 years.

Again good idea/app overall
