Simple and effective, but I have some issues with it. Whenever my internet is off, I have to manually open the app for it to notify me of anything at all, and sometimes it'll refuse to notify me even then unless the other person spams my DMs. Those two oversights makes the app less viable for urgent use, and sometimes I get yelled at for it even though it's not my fault, it's the app not notifying me.

It has great potential. It has some places where it needs improvement. Let me begin with saying I use it almost daily as communications between my desktops, phone, tablet, and laptop. Sometimes it tells you you are online but you aren't. It is hit and miss (mostly miss) for sending pictures. There is no way to see who else has Trillian to be able to enlarge your circle of friends. Bottom line, if you need something basic this is great but if you need something more than just the basics, no

I used to love Trillian. Over the years they've added more features and, sadly, given up on reliability. For example, my son sent me a message that I received on my computer almost instantaneously and the next morning - 14 hours later - the message finally appeared as "new" on my phone. This is commonplace and messages are NEVER received on our phones with any rhyme or reason. We are now researching alternatives. Tril, you'll be missed, but not as much as the important messages I never received.
