## What is Wi?

This is an UNIQUE and ONLY tool in the App store.

Is your wireless network optimized for VoIP or Voice over WLAN(VoWLAN)? Does the deployment of 802.11 improved the inter AP roaming performance? Any RF(radio frequency)coverage blind spot? This is the tool designed to measure and optimize/improve your WiFi network with real iOS devices, the iOS end users' roaming satisfaction will be improved after RF optimization.

The roaming of 802.11 is a complex process, 
the client(phone or other mobile devices) made the decision when it shall roam to a new AP(access point) once it feels the signal level has been lower than the threshold.

WiFi roaming time can be divided into two interval in general,  first interval is the new BSSID association and second interval is the data traffic actually switched from new AP to the client, the tool measured the first part from the client’s own OS point of view, the total time that the 
client(iOS) accomplished BSSID association to the AP, in this manner, different brand of AP or same brand of AP enabling/disabling different feature(e.g 802.11r fast roaming or OKC etc)will affect the BSSID switching time, by measuring the time, the tool can be used for

1. A quick and handy WiFi RF Survey tool, for a poor of WiFi deployment, it will leave some signal blind spot or weak signal area, by reflecting on the tool, the roaming time would be dramatically huge(in weak area) or totally NO roaming(blindspot area)being shown as a new association(since the original signal from first AP was lost due to too weak and NO new signal from new AP can the client being associated with).

A typical RF survey tool generate heat map by collecting AP signal level either from very expensive handheld device or by laptop attached with a USB WiFi adapter, both rely on the 3rd party WiFi adapter antenna gain NOT by real client(iOS)’s own antenna gain, what’s more, this way is too “heavy” for a quick and easy RF survey.

If there is an RF coverage gap causing iOS device association fail,  the App will sense it and will NOT record the failed roaming, from the report page, you will notice the gap and then notice the RF engineering team.

2. A reference testing tool for AP’s RF quality from the client’s own OS layer point of view. 

This tool designed not only for administrator but also for regular users since it also supports ping(ICMP), with the most advanced options being supported, e.g fast ping, multicast and broadcast ping, ToS(type of service) or QoS(Quality Of Service), jumbo packet etc.

Features:
- Graphing roaming test result to easily find out the longest roaming time caused by not optmized Wi-Fi AP deployment
- The only Ping(ICMP) implementation on IOS that supports advanced ping options.
- min/avg/max RTT(round-trip time) output to compare test result of static and roaming scenario
- Supports setting of ToS(Type of Service)  to simulate the Voice or Video traffic(roaming with high priority traffic)
- Supports fast ping to simulate file downloading sort of high speed traffic(roaming with high speed traffic)
- Supports multicast and broadcast ping(roaming with VLC multicast video or multicast video conference, the broadcast ping will find out the rest host within the same subnet)

## Key features

- Graphing roaming test results
- Advanced ping options
- Min/avg/max RTT output
- Set ToS for voice/video simulation
- Fast ping simulation

### 5/5 — This is a great tool for fine tuning Wi-Fi networks.

*2025-10-04*

My wireless team uses this tool for fine tuning our new large venue wireless networks deployments. It works great identifying gaps and problem areas. This app can be more perfect if the broadcasted access point name in the beacon is added to the view between SSID and BSSID. This will help identifying APs on the fly when doing long and complex roaming tests.

### 1/5 — Rubbish App

*2020-11-30*

Don’t waste your money

**Developer response:** Sorry to hear that, could we know what's the problem and how can I reach to help you?

### 2/5 — Buggy and questionable results

*2020-02-28*

App always reports packet loss on my XS Max when there is none. It always drops the first packet it seems. 

The SSID is too high up on the page so I can’t see it on the screen. 

Quite frequently the app will crash when pressing start. 

i Didn’t ask for a refund as I’m sure a lot of work had gone on here but unfortunately I wouldn’t trust this app to be giving accuarate results.

Seems app was last updated 6 months ago.

**Developer response:** Thanks for the feedback, the UI code will be update to adapt different devices.

### 1/5 — The Graph is useless

*2019-05-18*

Doesn’t graph live, only when completed.   The graph only shows three data points.  The only redeeming quality for this $10 ping tool is that it shows the BSSID on the screen alongside the ping responses.  Does some math to show transition time in a text dump at the end of the run.

**Developer response:** Thanks for your feedback, actually the tool does more complicate design and calculation than your assumption and it does help customers a lot in a long period of time, e.g just review the customer comments from Germany and US, wish you have a good day :-)

### 5/5 — Quick and dirty

*2019-05-09*

As a wireless engineer I’ve found this a great quick and dirty tool to have remote users give me stats.  It’s not Cape, Ekahau, or Airmagnet, but it gives quick useful info!

### 1/5 — Report and Graph functions fail

*2019-02-18*

The app does not work as advertised on iOS 12.1.1.  Don’t buy w/o seeing a vendor update announcement.

**Developer response:** Thanks for your feedback, please contact asolutioncontact@gmail.com for quicker response, a new build was submitted to App Store, please update your comments, thanks a lot and have a great day!

### 2/5 — Flores closes

*2018-05-07*

Keeps force closing

**Developer response:** Please contact asolutioncontact@gmail.com as posted in support webpage, we will help you to figure out the root cause, thanks!

May 10: Could you update yoir comment since it works after reinstallation?

### 4/5 — Useful for checking AP deployment

*2017-10-15*

This is very close to what I was looking for to verify connectivity and roaming through my Ubiquiti installation. The one change that I would like to see is to replace the running timer, which has no value to me, with the current RSSI. That’s what the iPhone uses to determine when to roam, and I’d like to monitor that along with BSSID and pinging. There’s another app that shows RSSI, ping, and BSSID on different tabs, so this is slightly more convenient, but is missing RSSI.

### 3/5 — A good start, but needs improvement

*2017-06-28*

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.

**Developer response:** WiFi roaming time can be divided into two interval in general,  first interval is the new BSSID association(auth->associate, in general it only takes a few ms if you analyze the packet sniffing file), however that’s the time reported by 3rd party tool not from the client’s own OS level, so even 1ms delay would be matter)and second interval is the data traffic actually switched from new AP to the client(this part takes much longer time), the tool measured the first part from the client’s own OS point of view, the total time that the 
client(iOS) accomplished BSSID association to the AP, in this manner, different brand of AP or same brand of AP enabling/disabling different feature(e.g 802.11r fast roaming)will affect the BSSID switching time, by measuring the time, the tool can be used for

1. A quick and handy WiFi RF Survey tool, for a poor of WiFi deployment, it will leave some signal blind spot or weak signal area, by reflecting on the tool, the roaming time would be dramatically huge(in weak area) or totally NO roaming(blindspot area)being shown as a new association(since the original signal from first AP was lost due to too weak and NO new signal from new AP can the client being associated with).

A typical RF survey tool generate heat map by collecting AP signal level either from very expensive handheld device or by laptop attached with a USB WiFi adapter, both rely on the 3rd party WiFi adapter antenna gain NOT by real client(iOS)’s own antenna gain, what’s more, this way is too “heavy” for a quick and easy RF survey.

2. A reference testing tool for AP’s RF quality from the client’s own OS layer point of view. Even the 3rd party sniffing tool is not 100% accurate because of unavoidable delay, it is only a mater of how much delay it will bring in by the sniffing hardware and software in a matter we can ignore it or not.
 
The idea of the tool was originated from me 100% not porting from others by the way.

### 4/5 — Very useful. would like export functionality

*2016-05-10*

The IMCP time feedback and roam time output are great.  It would be awesome if the text data could be exported (other than a screenshot).
