Numeric and graphical red-yellow-blue readouts of signal strength of wifi and cellphone. Color indicators are accurate for my phone. If you suspect the signal is weak, good to open the app for confirmation, then walk around to find where's a spot where the signal is strongest. Also a Latency indicator, reads in milliseconds or Fast/Ok/Slow, since the quality of the WiFi access-point's connection to the internet can be troubled, even though it's providing a strong signal to your phone. Lots more.

Nice simple clean layout, it looked good for a second. Ads we're small and non-obtrusive at the bottom of the screen. It shows the signal in asu, not dbm. However, I sat here for a minute watching it and thinking about it, and it popped up a full page ad in my web browser. Oh heck no. I am okay with ad supported, I am not okay with ads taking over my computer. Thank you for removing full screen ads, the updates look good.

Very basic WiFi/cell signal strength (not enough to be useful, though), the ads are REALLY distracting, and there's no way to close the app except via force-kill. There are other free apps with ads that aren't so obtrusive and far better common information. The app does passable job at reporting your cell connection strength, but it was pretty useless for WiFi. (Other apps offer basic information, often with drill-down ability to obtain advanced details; this app lacks both or it was not obvious to find and, in either case, it's not clearly available at all.) I was going to give this app 3 stars instead of 4 since it had a repeating obnoxious animated ad covering the bottom of the screen with no way to hide it, and it was REALLY distracting. But when I tried to close the app, it failed to do so, instead changing to a full-screen advertisement with the only option to purchase something. DING! Instant 1-star rating.
