Predy is a study timer and planner that helps you start studying, stay consistent, and make your progress visible. Use a study timer, Pomodoro, stopwatch, or manual entry to track learning time and build a routine that lasts. In Predy, goals are organized as projects, with tasks and work logs contained within them. Tasks can be managed by project, priority, deadline, and estimated time, preventing work from becoming scattered. Because all work logs are tied to projects, progress accumulates automatically, making it easy to see where you stand. Estimating required time in advance also helps users realistically understand what it will take to reach deadlines, reducing failed plans. The first problem Predy tackles is “not being able to start.” Work tracking supports Timer, Pomodoro, Stopwatch, and manual entry, allowing flexible use depending on the task and mental state. StudyWithMe mode further lowers the barrier by creating a focus-friendly atmosphere with immersive visuals and ambient sounds. On days when starting feels hardest, AutoPilot is especially effective. With one tap, a 2-minute timer begins alongside a simple starter action, such as tidying your desk. After that, you naturally move into a focused 20-minute session. This uses behavioral activation—you don’t start because you’re motivated; you get motivated because you started—minimizing resistance and building momentum naturally. Predy is also designed to make you want to continue. Daily login and task completion bonuses grow with streaks, while rankings visualize productivity through multiple metrics such as project completions, focus level, efficiency, total work time, and consecutive days. Even “just one minute today” feels meaningful, often leading to longer sessions. Consistency is supported not by grit, but by structure. Progress is clearly visible through analytics that show work volume and time for today, this week, and this month. Seeing effort accumulate creates a sense of achievement and naturally leads to “Maybe I’ll do a little more.” Predy’s core differentiator is Prediction. Before working, users estimate how long a task will take and compare it with the actual result. Feedback at project completion helps clarify why estimates were off. Repeating this process improves planning accuracy, reducing deadline overruns. Predy doesn’t just manage tasks—it trains how to plan. Predy isn’t only for your best days. It’s for people who tried task management apps many times and couldn’t keep going. By lowering the barrier to starting, creating reasons to continue, and leaving visible proof of effort, Predy helps users try again. From “I have to push myself” to “I’ve already moved forward.” Predy is designed to make that state part of everyday life.
