1 kg is 1000 g. 1 m is 100 cm. Unit Conveyor shows what happens to a number when the unit changes — so children see it, instead of memorising it. ■ The unit staircase Length, weight, volume and time units are laid out as steps. Send a crate up a step and the number gets smaller; send it down and it gets bigger. The crate travels between steps so the cause is visible. ■ The conversion line Four boxes come down the conveyor. Pick the one with the right answer. The wrong boxes are not random numbers. "Counted one zero too few", "multiplied instead of divided", "split an hour into 10" — each one is built from a mistake children actually make. So no box can be dismissed at a glance. Every question needs real thinking. ■ Shipping slips (word problems) "We used 2 m and 50 cm of ribbon. How many cm altogether?" Matching two different units before adding them is a separate skill, and it gets its own line. ■ Report Shows the percentage correct for each unit, so you can see which unit needs practice. ■ Safe to hand to a child ・Free. No in-app purchases and no subscriptions ・Ads appear only on the report screen, never while a question is on screen ・No full-screen ads and no video ads ・Results are stored on the device only, and are deleted with the app ・No camera, microphone, location, contacts or notifications Designed so a primary-school child can use it alone.
