"Illustration Vision Training" is a child-friendly app designed to enhance visual skills through interactive exercises, crucial for day-to-day activities such as reading and sports. Aimed at ages 2-6 and those in special needs education, it provides a playful platform for vision training, which involves improving eye movement control and hand-eye coordination. Developed by a teacher with 15 years of experience in special needs education, the app addresses the inefficiencies of traditional vision training methods, offering an accessible, anytime-anywhere practice tool. This addresses the necessity for continuous and repetitive tasks to build visual skills, which are foundational to learning and activities in daily life. The app includes features that allow for adjusting the difficulty to suit developmental stages, from the number of items to be matched to the number of illustrations displayed. A simple interface ensures ease of use, and a marking system helps track progress. It's designed for repeat use, making vision training an engaging experience. Offered for free to ensure wide accessibility, the app supports the development of various visual skills, such as visual acuity, coordination, focus, visual information processing speed and accuracy, memory, and efficient learning. These benefits are not limited to those with visual impairments; anyone looking to maximize their visual potential can benefit, enhancing both academic performance and overall quality of life.

About

Unit Conveyor

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.
