3 stars: Great app. Very useful for finding/verifying which frequency band your phone is using/receiving. Also it shows you the direction and approximate distance to your connected tower. However, it only shows which band my phone is using about half the time. Which is the only reason I need this app. Soooooo.....half of the time (maybe a smidgen less) it would receive a 5☆+++ rating. The other half of the time it would receive a 0☆ rating.
2 stars: Had to download this app according to the cell signal repeater I purchased. The map option to locate the tower to aim at is a joke. It would point straight out in the ocean and I'm pretty sure that the tower is not out there. The tower is 2 miles away from my house and the arrow still didn't point anywhere close to where I know that the tower is.
2 stars: NO support of carrier aggregation. phone can be connected to three different bands at the same time but this app does not indicate any of that at all completely distorting the picture and missing the point. Must show all aggregated bands and bandwidths to be of any use. do developers even know how 5g works? showing only the anchor lte band is useless!
