не работает

Один раз запустился тест. После перезагзки приложения перестал подключаться к серверу. Собстенный сервер вроде поднимает, но подключится не смог.
Интерфейс тоже глючный. В общем денги на ветер.

Response from developer

Здравствуйте, и спасибо, что подробно описали проблемы, это очень помогло. Приносим извинения за неудобства; то, с чем вы столкнулись, мы воспроизвели и исправили в ближайшем обновлении: • Подключение к серверу перестаёт работать - снизили число параллельных потоков по умолчанию и переработали обработку обрыва соединения: теперь вместо непонятной ошибки приложение показывает, что сервер недоступен, и предлагает повторить. • Свой сервер поднимается, но подключиться не удаётся - на Mac частая причина в том, что показывался не тот сетевой адрес (особенно при включённом VPN) или система блокировала входящие подключения. Теперь приложение показывает все локальные адреса на выбор и подсказку, как разрешить входящие в настройках брандмауэра. • «Глючный» интерфейс - устранили подвисания окна на Mac во время теста. В ближайшие дни выпустим обновления.

1.7.6 作为客户端使用时没有反应

1.7.6 作为客户端使用时没有反应,使用其他的客户端连接 1.7.6 的服务器是可以的。

Response from developer

Thank you for the report, and sorry about the trouble. We’ve already released newer versions after 1.7.6, so please update to version 1.7.8 and try again. If the issue still happens, please send a few details: - your macOS version, - whether you are using TCP or UDP, - the server host/port, - and what exactly happens when you start the test. That will help us reproduce and fix it faster.

Working Wonders!

Able to move from site to site and test from different environments. Developer responded quickly and I was able to update and get it working asap! Will be trying the Android version this week and reviewing there as well. Thank you Vladimir.

Response from developer

Thank you for updating the review. Glad it’s working properly now, and thank you for your support.

Not compatible with Sequoia?

Had to go with iPerfman Pro cause I wasn’t able to add a server at all. If its fixed I’ll come back.

Response from developer

Thanks for flagging this, and sorry for the frustration. You were right: in an earlier macOS build, some users could not add a server. This has been fixed in the latest version, including improved compatibility on macOS Sequoia. Please update to the newest release and try again. If anything still looks wrong, contact us via in-app Feedback and we will help right away.

Amazing app

The app is beautifully crafted and has a lot of functionality. Results are precise and you can tweak the tests. Very good!

Response from developer

Thank you, dawvik! 🙏 Really happy to hear you like the design and the level of control over test tuning. If you ever have feature requests or run into any issues, please send feedback from inside the app — I’m actively improving it.
