Measure performance (Bandwidth between 2 devices.) on two Apple devices within the same subnet.(iPhone/iPad/iMac) For example ・Near the WIFI router,but performance is no good.. ・check wifi performance & reliability. Please use app for problem analizing such. usage) One is a measurement terminal. The other is Partner, it is a response terminal. select Measure / Partner at first time. (Partner) This is response device side, the standby state is immediately entered. There is the two-dimensional code with of the IP and port number of this terminal in screen center. This code is used cominucation infomation by the measure devie. Below that code, current using IP is displayed. If you have multiple IPs, you can change them with the IP button. (Measure) This is measuring device side, we must set Paertner device IP and this device IP. Paertner device IP is readed the 2D code of the partner device with the camera. The current using IP of your own is displayed under the partner device IP. If you have multiple IPs, you can change them with the IP button. The measurement results differ depending on the type of device. Especially, the difference on the measurement side is remarkable. This depends on the TCP / IP processing performance (congestion and processing performance) of the device. You can remeasuring with the update button on measuring screen. Press and hold this button (about 3 seconds) to switch between continuous measurement mode and single measurement mode. ## Key features - Measures bandwidth between two devices - Analyzes Wi-Fi performance and reliability - Uses one device as measurement terminal - Uses another device as partner response terminal - QR code for easy connection setup - Supports continuous and single measurement modes ## Frequently asked questions about WifiRtt ### What is WifiRtt used for?

We changed this function to the transfer speed between two devices. Because we realized that bandwidth measurement is more important than the traditional function. It also supports IPV6 and wired LAN, so please analyze network problems. Two iOS devices are required for measurement. ### 1.3 — 2021-02-18 fix ios14 change Admob framework ## Apps similar to WifiRtt | App | Rating | Price | Category | | --- | --- | --- | --- | | [Milkplan App](https://appshunter.io/ios/app/milkplan-app/id1520251500) | — | Free | Utilities | | [戎家](https://appshunter.io/ios/app/id1515514500) | — | Free | Utilities | | [MeritAgCheck](https://appshunter.io/ios/app/meritagcheck/id1518293620) | — | Free | Utilities | | [QR Code Reader & Barcode Scan](https://appshunter.io/ios/app/qr-code-reader-and-barcode-scan/id1521174180) | 4.8 (71) | Free | Utilities | | [XL Lock Manager](https://appshunter.io/ios/app/xl-lock-manager/id1516525800) | — | Free | Utilities | | [去电话来电话-智能发短信](https://appshunter.io/ios/app/id1513115300) | — | Free | Utilities | ## More apps by uto toshiki - [calcS16lite](https://appshunter.io/ios/app/calcs16lite/id876927510) - [calcS16](https://appshunter.io/ios/app/calcs16/id962408149) - [colorChopper](https://appshunter.io/ios/app/colorchopper/id965910925) - [fucusViewFree](https://appshunter.io/ios/app/fucusviewfree/id972447348) - [Coro.](https://appshunter.io/ios/app/coro/id1017066209) - [Coros.](https://appshunter.io/ios/app/coros/id1022442989) All apps by uto toshiki: https://appshunter.io/developer/876927513 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
