User reviews

Missed opportunity, no reflector support

This app will only work for DStar callsign routing, and is lacking much needed features for reflector support. It would make the D52Plus terminal mode useful, where now it is not at all for most users.

不安定が改善されているのか??

このアプリが出てすぐに使用したが、家庭内のWi-Fi接続時のみ利用可能、外出先では全く繋がらない。使えないアプリだった。
今回のアップデート?で改善されたか?再度ダウンロードして試してみる。良くなっていると良いが、、、

バージョンアップするもダメ

バージョンアップしても、モバイル通信では使えない。

iPhoneの電話回線でつながらない

iPhoneでWiFi回線だと直ぐにつながりますが、やはり電話かいせんだとfailed to network を表示してつながりません。改善を望みます。

かなりダメなアプリ 改修を望む。

iPhoneのWiFi接続でのターミナルモードは簡単に接続できますが、電話回線を使っての接続はかなり難しい。iPhoneの再起動をする度にアプリを立ち上げても、ほとんど繋がらない。iPhone側の問題かどうかの切り分けに、eSIMから物理SIMへの交換、iPhoneの基板交換もしてみたが、変わらない。今のところIPADでは使えるが、iPhoneでは使い物にならない。
