Очень большие искажения. ### 4/5 — Хорошая, но *2025-08-09, version 1.7* Но звук по блютуз отправляет искаженный и пользоваться пока квп по блютуз невозможно, нет декодирования сигнала. С тем же блютуз модулем на андроиде такой проблемы нет. Видимо проблема с блютуз осталась. Пож-та исправьте. Пока только со шнурком, но айфонов таких с джеком 3,5 уже скоро будет не найти). Спасибо. ### 4/5 — Подписка *2023-10-25, version 1.3* Не видит оформленную подписку ### 3/5 — Interesting app… *2023-07-30* Nice app, but the free version is limited to a small amount of characters. I would gladly pay a reasonable one time price but not a subscription. ### 5/5 — Фантастика! *2023-06-16, version 1.3* Как же доооооооолго я его ждал в Apple store. Отличное приложение. Позволяет пробить эфир там где голос уже не различим. ### 5/5 — КВ пейджер *2023-04-23, version 1.3* Отличная программа, ни чего лишнего. Отличная поддержка, выявляемые проблемы быстро устрашаются, обратная связь тоже отлично работает. Спасибо. ### 5/5 — Отлично ! *2021-11-16, version 1.1* Наконец то сделали под iOS !!! Огромное спасибо ! Долгожданный контент. ## Frequently asked questions about HFpager ### What is HFpager?
