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, Google Talk, ICQ, and Jabber.

Great FREE app for more than a decade- Thank you!

I’ve been using this app for probably 15 years or more. I paid for premium for one year and wish I’d have just done the lifetime membership because I love this app and use it over every other one for chat.
I loathe other chat apps (FB messenger can go diddle in the corner). Thank you Trillian for making a TRUELY FREE TO USE app that does as promised.
Thank you for not removing features every year in an effort to force us to pay. Thank you for offering incentives to go premium. Next time that lifetime member deal pops up, I’m taking it.
Because I thank you for making it simple, convenient and consistent enough that I can keep using the same app without having to start over.

Handy App

I use this app to keep in touch with friends all over the country. I like that I can send and receive pictures. I use it everyday and have never had any problems. Good Job.

Annoying new bugs

All chats get flushed Sunday mornings. Frequent long reconnect pauses during use. Used to be a reliable app. May have to search for a replacement.
