Any good suggestions on PIM software recommendation?

I want to a tool that can manage repeating tasks and reminder me at right time; create custom fields(because we're in fiancial area) and I can edit them; support windows pc and iphone data sync. I search there's software named Efficcess, has someone use it? Is it good?

  • Your Japanese radio recommendation? To practice listening to Japanese I listen to Japanese talk radio. My favorite station that I found was Sea Wave 76.2 FM Iwaki. But now, that station doesn't work with my iphone anymore. Can a Japanese person please recommend to me a Japanese Talk radio station? I don't want a lot of music. Just Japanese talking.
  • Security recommendation for iPhone? Ok so I have an iPhone 7 and when I connected with my hotel s Wi-Fi, it skips the security reccomemdation and immediately connects, with this, my phone has no Wi-Fi because it has no security recommendations yet. I have been spending the last few hours trying to forget the network and try again but it seems like every single Wi-Fi network, my phone skips the security recommendation. What do I do?
  • Nightshift for iPhone 5C? Third party app recommendation? Ok so as you may know, iOS 9.3 came with the new nightshift feature which makes your screen more yellow allowing for better sleep. However, this feature is not included for iPhone 5C and down (5, 4S). Is there a third party app from the internet that allows the same effects? No jailbreaking required please. Link if possible. I do have a Mac if needed.
  • My iPhone 4s will not connect to my home Wi-Fi no matter what suggestions I try. Any suggestions? So I never had an issue connection to my home Wi-Fi before with my iPhone 4s, until 2 days ago. I have done everything; forgotten the network, reset the network settings, ect. No matter what I read on these forums, nothing seems to really work. I don't know how to do much with electronics and such, so things suggested like with the static IP and all of that, I don't understand. Please, if anyone can help me, I'd truly appreciate it.
