Time Detective

About

How long is 5 minutes? Is 30 minutes shorter than 1 hour? Time Detective helps young learners build an intuitive sense of duration after they have started reading clocks. Children compare two durations, arrange time cards, work out elapsed time, choose realistic lengths for everyday activities, and explore a visual timeline. Gentle hints turn minutes and hours into something they can see—not just numbers to memorize. • Start with 5, 15, and 30 minutes versus 1 hour • Progress to “What time will it be in 25 minutes?” and time across the hour • No countdowns, rankings, ads, or in-app purchases • Works offline • Supports up to four local learner profiles • Optional private cloud backup • Export and import learning records as JSON, CSV, or ZIP One purchase unlocks the whole app. Learning data stays on the device or in the user’s own private cloud storage. The developer does not operate an account, advertising, or analytics system.
