Trillian is an instant messaging app that works on phones, tablets, and desktops while keeping your chats neatly synchronized between all of them! We think conversation should be easily shared between all of your devices, not trapped as text messages on your phone. Here's how we do it:

• INSTANT MESSAGING: Your unique Trillian username can be used to send unlimited messages free of charge. Trillian uses your existing data plan and/or WiFi.

• ANYWHERE: Trillian's continuous client feature delivers your chats instantly between all of your connected devices. In addition, Trillian automatically silences push notifications on mobile devices if you're active on a desktop - no more dealing with a phone buzzing on your desk all day!

• SIMPLE: Trillian places a strong emphasis on fast and reliable message delivery and a beautiful, easy-to-use interface.

• SECURE: All communication with Trillian servers uses TLS to ensure third-parties can't read your chats.

• INTEROPERABLE: Of course, Trillian wouldn't be Trillian without support for Facebook Chat, MSN, Google Talk, AIM, ICQ, Yahoo!, and Jabber.

Wishing for the old version.

The new update may LOOK pretty, but as it often is with things, looking nice and being functional often aren't found together. I'm missing the older version of trillian, where it was fast and simple to browse through all my online contacts. I want to see them all at once, not hand pick six people and have them on my home screen and to see who else is on, I have to open a new blank chat and then add a contact? So much easier before. Mobile apps should be simple, clean and easy to use. I shouldn't need a few minutes to figure out a program that was perfectly fine before an update hit.
Edit: It's been a few months since the update and this program still crashes randomly several times a day. :/


I decided to finally write a review for Trillian. I switched between it and ebuddy for a long time, and quit Trill when it switched to it's current theme. However, ebuddy added ads that obscure the entire chat, so I quit then and there.

Now I use Trill all the time (even as I'm writing, I'm waiting on a reply!) and it's great. The 6 or so contact pane works great for me- I have lots of folks I don't talk to much, and it's great not having to stare at their names all day.

Only downside is the no notifications while at desktop dosen't work for me... Probably because I use it in browser? But I just log out on the phone, so it works well enough.

STAY AWAY - Abandonware, not updated in a year and a half

This isn't the first time Cerulean Studios has abandoned this. You can see my original review below the --- below.

Well, they've done it again. It took them TWO YEARS to get an iPad version way back, and now its been a year and a half without an update. This app DOESNT WORK ON iOS8. Stay away. Terrible Customer Service. Terrible UI.

Do not give in. Find something else.


The whole point of Trillian is the fact that it allows awesome interopability between all your devices. Log on at your desktop at work, at home, and on your phone. Everything stays in sync. Your phone doesn't beep unless you're not using your desktops. It is amazing!

Until you get an iPad. For months this company has been promising an iPad version. Before this app was free, many of us paid a chunk of change for it, and some of us paid for their Pro upgrades as well, all while they promised the iPad version was coming soon!

Well, after many months, it is time to give up. I'm going back to IM+, a better experience overall, since the defining factor of Trillian (syncing of all chats) is useless when an iPad becomes your primary device.
