Every planner I built worked... until the backlog hit 200 items

Solo founder here, launching Lunelo on June 8. The thing I keep coming back to: I've abandoned every planner I ever used, and it was never the features. It was the pile. 40 open tasks, then 100, then I stop opening the app because it feels like a list of everything I failed to do.

So I built Lunelo around one rule I almost talked myself out of: cap the day at ~5-6 real priorities. Whatever you don't finish just rolls to tomorrow, quietly. No red badges, no "overdue" guilt. Momentum, not a museum of debt.

The risk is obvious: maybe people actually want the big backlog as a safety net, and I'm removing something they rely on. I genuinely don't know yet, so before launch I want the honest version, not the polite one.

What actually made you stick with a planner long-term — or what was the moment you quietly abandoned one?
