Description by WOOKYUN JEONG Written by the developer, not by AppBrain. Click to read.
An AI to-do app that picks the one thing you can do now.

The new “What should I do now?” feature recommends the most actionable task based on your available time, place, energy, deadlines, and completion patterns. See why it was selected, start a 5, 15, or 30 minute focus session, and let CheckMate replan after you finish or skip it.

Workout Routines & Apple Health

Create a different workout for each weekday with the free manual builder, then complete it like a daily quest. The PRO AI coach asks about your goals, available days, time, and equipment before proposing a weekly plan. Apple Health connects read-only to compare planned sessions with workouts, steps, distance, and active energy. Raw Health data and analysis stay on the device.
