It is frustrating that the only way to get the data it downloads is to upload to their cloud platform and pay their subscription fees (which cost hundreds of dollars per device). ### 3/5 — 無事に使えました *2025-07-04, version 2.16.017* 製造元に問い合わせをしてiPhoneの言語設定を英語に変えたら使えるとの助言をいただき、設定を変えたら正常に使えました。言語設定を日本語のまま使用するとバグが起こりアプリが起動出来ないようです。 ### 1/5 — 表示されない *2025-06-04, version 2.16.017* iOS18.5でインストールしたが、初回起動時の通知と位置情報のダイアログ以降何も表示されない。現状使えません。 ### 1/5 — 使えません *2024-11-25, version 2.15.000* 開いても何も表示されていません ### 1/5 — 表示されない *2023-01-30, version 2.07.004* アプリは開きますが 開いても何も表示されません。 ### 1/5 — 開かない *2022-06-06, version 2.05.071* 日本語設定で開かないことを確認しました。早急に対応してほしいです。 ### 3/5 — 開きました *2021-10-11, version 2.0.12* 現在のバージョンでは、日本語設定にしている場合、開かないらしいです。 ### 4/5 — Great setup tool with big limitation *2020-02-05* The app is easy to use, makes it a breeze to setup ZL6 Data Logger in the field. However, it does not offer internet connectivity to ZENTRA Cloud. ## Frequently asked questions about ZENTRA Utility ### What devices are compatible with ZENTRA Utility?
