Comments on Trillian for Android

★★★★★ Malachi Meahl · Nov 29, 2024
I have used trillion since I was a teenager and the internet was new. It has changed over the years and things like aolim and yahoo and MSN have dropped off, but it is still useful, and I chat on it every day.
★★★★★ Arlene V · May 1, 2024
We use it at home and at work for years and years. Could not function without it.
★★★★★ S F · Jun 2, 2024
Love this app, lets me chat with almost anyone on almost any platform I have been using it for years through all my phones and computers, I have never needed anything else since I found Trillion
★★☆☆☆ Shawn Hall · Aug 27, 2024
I used to love Trillion. 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.
★★☆☆☆ beth · May 13, 2024
The app was alright before, maybe a bit buggy in that it wouldn't send the occasional message, send others twice, or wouldn't give notifications even though it had every permission to run in the background. Now, it refuses to send my messages to a specific person for at least a week, for no reason. Others work fine.
★★☆☆☆ Christopher McGlinchey · Oct 25, 2024
When using the app, I am notified I have a waiting chat, but I am unable to respond as I can't type anything in the message box. I then have to close the app and re-open it for it to allow me to type a message.
★☆☆☆☆ Paul' Gmail · Nov 27, 2025
Awful. Cannot log on or change my password. A waste of time.
