Plan90

Plan90's site doesn't tell you who built it, but it's clear about why it exists. The pitch fits in one line: "Ninety days. A few goals. One small step a day." Whoever made it has a firm opinion about how goal apps fail. They pile on dashboards, streaks and notifications until keeping up with the app turns into its own chore. Plan90's answer is to strip almost everything out. The design brief reads "Black, white, and a list," with serif headlines, square checkboxes and "nothing that blinks for attention." The FAQ explains the time frame: ninety days is "long enough for something real to change, short enough to see the end from the start."

The mechanic is simple. You pick a few goals, or write your own, and answer about a dozen short questions about your time, your level and what done looks like. An AI planner turns that into a 90 day sprint with a milestone for each month and tasks for each week. Each morning you get one short list. You only ever see today and tomorrow. If you fall behind, the AI rewrites the week. If you miss a day, it stays missed and the plan carries on. There's no streak guilt. The schedule builds in five task days and two lighter ones per week, so one bad Tuesday won't wreck the month.

The opinionated design is the reason to try it and the reason some of you won't stick with it. It's iPhone only for now, with no Android version. Three goals is the stated sweet spot, and anything extra waits in a backlog for the next sprint. You can't build sprawling project trees here. If you want a calm daily nudge toward a handful of goals, the restraint is the product. If you want a flexible task manager, this isn't one.
