Seems to be nicely working

Installed it about a week ago since whoscall is really crappy. Since then I only got 1 spam call, and JIMA successfully recognized it (I got it because I have that specific category not to be filtered). But I just don't really understand the mini-game and gems concept. And I suggest letting users voluntarily watch ads (by letting us ourselves to click and open ads) so that we can earn more gems and you can generate more revenue.

Very useful - suggest 「show all」 button

Already wrote review before. Very good. Very useful. Since free of charge, I don’t mind the watch ads feature.

New suggestion: In settings, each category (bank, telecom, beauty, etc) has the block/show switch. Can you add a button for “switch all” to block/show? 要每個category(只是每一行)選擇block或show比較麻煩,可以加一個「全部」選擇一次過啟動block或show的功能嗎?因為有時候真係要等銀行或電信公司客服的電話,我要確保對方可以打到電話給我,因此我會安全起見全部unblock,然後接完電話再block返所有category。試過沒有unblock,結果客服真的打不到電話給我。

Awesome app

I think Apple needs to give more flexibility for call blocking functions like this app provide us. We got thousands of junk call these days and JIMA call block save our lives. Whenever there is a iOS update, this app might fail to work until next update. Do something with that Apple. Awesome app, 10 out of 10.
