Proton Calendar Reviews

Very good but needs work

Essentials that are missing - can click and drag on a time slot to create new event (rather than having manually select the time slot from edit menu which takes forever) - editing the time - just give us 00,15,30 for minutes (takes too long to select through 60secs) - can label events with different colors Basically hope you can just mimic most of google calendar as they have it mostly right!

待望の暗号化カレンダー(日本語入力問題も解決)

追記: アップデートで下記の問題が対応され、日本語の変換もも問題なく入力できるようになりました！ Thanks for developer! ------------------ ずっと待ち望んだProtonの暗号化カレンダー。プライバシーにも重視していて、ずっとG社より移行したかった。ただ、日本語環境で入力する際に1文字目が変換から外れてしまう問題があり、なにか1文字入力してからタイトル等を入れ、それから1文字目を削除する必要があります。日本語に公式対応していないが、このバグは修正していただきたい。あとは既定の通知設定や開くマップアプリなどが設定できればより良いと思います。今後に期待です。

Really love this app, but is missing a few key features.

I am so happy to have this app. I’d been using the calendar website for a while now so I’m so glad the team made a native app! A couple of quirks on the app that’s making it hard to use: - when a calendar event is set on mobile, it cannot be edited through the desktop version, and vice versa - on desktop when deleting one event in a series it deletes one event; on mobile it will only delete all events in a series. This has caused some problems with weekly meetings of mine if I’ve had to skip one - cannot add participants on mobile I believe in the product and want to use Calendar full time, but especially these three points have made it hard to use for me. Keep up the good work y’all!

日本語入力の問題が解消

他のレビューで指摘があるとおり、日本語を変換する際に一文字目が変換対象にならないもいう問題がありましたが、バージョン2.3.0にてこの問題が解消され、最低限の使うのには文句がなくなりました。

I can't type comfortably in Japanese

Like this but…

I really like this calendar, but when I type something in Japanese, it gets cut off mid way. For example; if I want to type ひ(hi) it comes out as hい. I think a previous review brought up this same problem. If you can just fix this one thing, everything else seems fine.

待望の暗号化カレンダー(ただし日本語環境で問題あり)

ずっと待ち望んだProtonの暗号化カレンダー。プライバシーにも重視していて、ずっとG社より移行したかった。ただ、日本語環境で入力する際に1文字目が変換から外れてしまう問題があり、なにか1文字入力してからタイトル等を入れ、それから1文字目を削除する必要があります。日本語に公式対応していないが、このバグは修正していただきたい。あとは既定の通知設定や開くマップアプリなどが設定できればより良いと思います。今後に期待です。
