Software Reviews and Criticism

    One of the few great pro Windows apps left

    There has been a trend of terrible UI designs by recent app developers (think Skype, Slack, DropShare 5, etc.) I'm very happy that Trillian keeps the usable UI and pro feel without slashing features. I just switched from Adium since Adium has been long neglected. Trillian is very stable for me, and I haven't had a crash yet. I just wish it supported OTR encyption.

    i think this is a great chat client

    i have used it for years and i will continue to use it as long as it’s still around. I’ve never had a complant with it. I would like to see some more client intergration, maybe discord? and i would also like to see a dark theme on the phone. but other than that, it’s a solid app

    Great Business Use!

    This has been a great way for our business to secure chat with other employees. Its much cheaper than many other products for secure texting, and the features and support are top notch. Very happy with the purchase of the premises server and employees are able to use the system without much issue.

    Constantly freezes on startup

    This app has got to be the most unreliable app for messaging. Using it for work and we use Google Hangouts, it freezes and have to force quit. If it does start, it freezes if I come back to wake my computer from sleep. It’s a shame because the mobile version is great, but this has been a constant problem for the past couple years. I keep sending the error reports to Microsoft, but nothing I guess is ever fixed? Love the app, just needs to be more reliable….

    Awesome! Just one thing

    I have a Pc for my own personal Trillian, and I use the Pc app. I have a Trillian for work, and my work computer is Windows. One thing I have noticed is that with the Pc desktop app, my status updates and shows if I am idle, and at what time. My windows desktop always says I'm Online on my screen, no matter what. Even if I am idle for an hour for lunch, the status on my screen and my profile show that I'm online, but to my coworkers my status says I am away. My hope is that the fix the windows desktop version to update the status on my own screen so it says when I changed to idle. The Pc version does a great job of this
