This official Tau Lambda Chapter App is for members of the chapter to find out about our events, chat with Chapter members, View Chapter Documents, Chapter Directory, and much more. The ability to effectively communicate with Chapter members will help us continue to develop leaders, promote brotherhood and academic excellence, while providing service and advocacy for our community. The App also allows guest to view many features of the app in the GuestView. Guest can also receive push notifications of Chapter and Community events. As a Guest you can also contact the Brothers, with any questions, or comments. Tau Lambda Chapter was organized in 1926, at what was then called Tennessee Agricultural and Industrial State College at Nashville, Tennessee, after its application was accepted by the General Convention. Brother Maney Owen, president of the Chi Chapter (Meharry Medical College), set aside the chapter in January, 1927.

Escape the infinite feed. OneTopic is a daily poll and discussion app — one global question, every day. See what the world thinks. Vote on one global question a day, read perspectives, and join a single global conversation that resets your attention instead of stealing it. No infinite feed. No algorithms. No doomscrolling. Just one question that the entire world answers together. * ONE DAILY DEBATE Every day a new question drops. You choose your side and see how opinions shift across the world. * GLOBAL VOTE IN REAL TIME See exactly where people stand on today's most pressing topic. Some days the world agrees. Some days it splits in half. * FOCUSED DISCUSSION Share your perspective without the noise. Engage in civil, focused debates on a single topic instead of a million competing voices. * NO ALGORITHMS. NO NOISE. No feed deciding what you see. No pressure to perform. Just people, ideas, and one shared point of focus. * SHAPE TOMORROW'S QUESTION The next big question could come from you. Start a conversation the entire world wakes up to tomorrow. Maybe the problem was never social media. Maybe we just forgot how powerful it is to concentrate on one thing at a time. This isn't just another social app. It's a daily ritual for thinking together. Download OneTopic and return to clarity. One question ends. Another begins. And slowly, we understand each other again.

The clearest difference is update cadence: OneTopic at every 9 days against Tau Lambda's every 39 months. OneTopic also leads on iOS requirement (13.0 vs 16.1). On price, ads, in-app purchases and device support there is nothing between them.
