さらに見る ・無料版でも通信速度の折れ線グラフ表示可能だった。自動縮尺で便利。・有料版なら「Notification Kit」が使えるが,「RAM usage exceeding limits」,「Device temperature reaching abnormal levels」のみ対応で,通知領域での通信速度表示には非対応。つまり他アプリ「InternetMeter」のような機能はなし。さらに「通知を受信するには(中略)ウィジェットの1つをホーム画面に配置する必要があります」点に注意。・メモリ解放機能(「RAMメモリをクリーンアップ」)があるのが売りだが,どうもフリーメモリ(空きメモリ)をずっと小さく見積もる傾向があるようだ。他アプリ「ActMonitor」や「Usage - Device Monitor」に比べはるかに少ない空きメモリ容量を提示する。しかも「free」の日本語訳の誤りで「無料」と表示され,わかりづらい。しきい値最大の99%に(初期値97%から)変更してもメモリ不足の警告が頻繁に表示され鬱陶しい。しかし改善方法がわかった。アプリ画面左上の「設定」で「非アクティブなメモリを非表示」をONにすることで,ActMonitorとほぼ同じ空き容量表示になり,頻繁な警告から開放された。さらに同じ設定画面で,「更新頻度(s)」(「ネットワーク情報は毎秒独立して更新されます」)を初期値2秒を10秒(最大30秒)に変えたりして。ちなみに,これまで手動でメモリ解放しなくても困ったことはなかった気がする。古いAndroid端末でメモリの少ない機種では別だったが。ときどきiPhone再起動必要になったことはあるが,メモリ不足とは違う原因の気がする。※ iPhoneSE2,iOS18.5 にて確認した。
