Comments on Trillian for Android

★★★★★ Ivor Gatland · Dec 11, 2024

I have used Trillion for years and years and cannot fault it.

★★★★☆ Jordan C. Seidel · Sep 16, 2025

I'm not sure if it's me or the application, but I'm unable to simply hit control a to highlight all the text I dictated into the app I must use my mouse to highlight it which is irritating and holds up my productivity

★★★★★ Willie whiters · Oct 4, 2024

It seems like a good site, but I am new to the site, and I can't add pictures or anything to my messages. I have now figured out how to add pictures to trillion. I have been on Trillion for a few months and have learned how to navigate the site a lot better now. It is quite an interesting site.

★★★★★ Marc Williams · Jul 1, 2026

I used Trillion when it first became available last century. If I consulted for a company Trillion was one of 4 programs I insisted on everyone uses whom I'd interface with. Is this APP similar to that or is it entirely new? Thank you

★★★★☆ Cad Delworth · Aug 1, 2026

An excellent I'm, my one criticism being that enabling Text Formatting changes hyphen-space at start of line to a bullet point. I sort of see why, but I tend to start a line with hyphen-space when it continues the previous line, if you follow me?

The latest version is such a downgrade in function and appearance. I updated in hopes of having the Klipy GIF picker, and now I have to deal with frustrating animations when sending messages, lag when typing, and unintuitive settings layout. It even forces reset my settings when I updated, blinding me with light mode (which I will never willingly use). I also can't use the built-in camera app anymore because it flashes the screen blinding white on capture.

Use this app for work. After last upgrade, we get not sound notification on our work or personal phones when a message is received. NO ONE seems to be able to fix this problem!

★★☆☆☆ Anna Swanson · Oct 4, 2025

Chat is deleted-not good I wouldn't use trillion if I had the choice

★☆☆☆☆ R X · Jul 21, 2026

Glad its getting updated. Keep it up if possible this is our fav messenger. Also happier with tje bugs being fixed now. So far its gotten better. Also if needed i jave info on how its effected our phones. Mine has problems launching from app button. It stalled out in black screen then restarted our phone partially. Then once it restarted and i re-did my screen lock (after being locked out when trill was restarted). It was working again no prob starting the second time but its always 2x to fix it
