A good start, but needs improvement – Wi-Fi Roam Test Tool Review

The app attempts to provide useful information about your iOS device's roaming behavior. What it does well: 1. It shows you the BSSID your device is associated to at the moment. It updates this as you roam. 2. Shows a continious ping to a host of your choice, while you roam. What needs improvement: 1. It comes up with impossible roam times (4ms, 5ms, etc.), when in reality it's more like 40-80 ms. The method it is using to calculate roam times is flawed, and misleading. Doing a over-the-air 802.11 frame capture your iOS device's roaming behavior with a professional tool on a laptop will give far more accurate results. If accurate results can't be done, the roam time measurement should be removed from the app. It's completely misleading as it is. 2. The BSSID is displayed incorrectly if there is a zero in the first digit of the octet. For example, if the actual BSSID was "00:1a:1b:1c:1d:0e", it would display it as "0:1a:1b:1c1d:e". This should be simple to fix. Just don't drop the leading zero. 3. The UI doesn't appear to follow Apple's design guidelines. It looks like an Android app that was ported to iOS, with little though to how it should look. Summary: It's great to see what BSSID you are associated to, and when you roam. The rest is less useful, or just plain misleading.
