I used it for along time and it did what it's supposed to do, but then I discovered that if you run the Korean version, you get rewards. The English version runs adds, but no rewards. So I think "No problem. I'm in Korea, I'll install the Korean version. " But I can't! The play store only shows me the English version! Edit in response to the replay: As stated, I am IN KOREA meaning I can use the rewards, and I don't have the Korea version because the Play store does not give me the option to install the Korean version.

Hello, this is Dr.Capsule, A Smart Does for Android Security💊 The reward system is unavailable in Dr.Capsule(ENG), so the language setting on your phone must be 'Korean' in order to use Dr.Capsule(KOR). If you have any other questions, please leave a review or send us an e-mail(drcapsule@estsecurity.com). Thank you always, have a good day (:˒| )

excellent. very similar to 360 security (as it's by EST also) However it's advert free, other than small banners on the bottom of pages. Good work fellas!! # update after a few months of constant use - What a great Free App! A miniscule amount of ads at the bottom of the page (not at all intrusive).... Can't praise this enough. Have used other apps and this has to be the best - MANY THANKS GUYS! #

This is a great way to ensure apps that run in the background are shut off/closed, especially if you are running low on battery power. I have found a few apps with Dr.Capsule that have gained permissions that I did not allow them to, looking at you Amazon Prime Video. I feel safer knowing this keeps my app secured and running quickly.
