Focus challenged folks: What tactics do you use to focus?

I don't know if anyone else has the experience of trying out a new focus app or tactic, it works wonderfully for 2 weeks, and then needing a new tactic to stay on task. I've tried variations of the Pomodoro method, which works when I'm WFH but not so much when I'm in office interacting with the team. Has anyone found a long-term solution that's worked for them? If anyone has a focus/strategy app launching soon, I'd love to check it out!
