Zetamac Arithmetic Practice vs Doodliqo

Zetamac - A mental math practice app used in the Quantitative Finance world.

Doodliqo is a colouring book and first-letters game for young children — the kind of app you can hand to a three-year-old without hovering over them. TWO WAYS TO COLOUR Tap a numbered area and it fills with that colour. Or pick up the brush and draw freely: the paint stops at the lines all by itself, so a picture is never spoiled and nobody has to start again. Thirty-five pictures across animals, vehicles and everyday things — a cat, a fire truck, a lighthouse, a dinosaur, a hot-air balloon — and rainbow, sparkle and spotty brushes to colour them in with. LETTERS AND NUMBERS, WRITTEN PROPERLY A to Z and 0 to 9. The letter is shown on a small card, the page is blank with a writing line, and your child copies it themselves — there is no stencil to trace over. Doodliqo looks at the shape they drew and gently asks for another go until it is right, so a letter gets practised until it is properly formed. Every letter says its sound as well as its name, and then shows a word it begins. B says buh. B is for Butterfly — and the butterfly is right there to colour in. SPOKEN ALL THE WAY THROUGH Tap red and it says "red". Finish a picture and it spells the name out, one letter at a time. Write a number and count that many apples together. Nothing a child needs is hidden in writing they cannot read yet, and every button says what it is when you tap it. FIVE GAMES Matching pairs, a find-the-picture listening game, letter sounds, a colour hunt and jigsaw puzzles — all built from the same pictures they have been colouring. THEY KEEP WHAT THEY MAKE Finished pictures are saved to a gallery to look at again, and every picture coloured turns into a sticker for the sticker park. MADE FOR SMALL HANDS Big buttons. No menus to get lost in. No timers, no lives, no way to fail. If your child stops halfway through a picture, it is waiting for them next time. FOR GROWN-UPS Behind a simple parental gate you will find sound and voice controls, a break reminder you can set, and a way to erase progress. There is no sign-in, no chat, no camera and no microphone. Nothing your child draws ever leaves your device, and we collect no personal information about them. Doodliqo is free and supported by advertising. Ads are always non-personalised and rated for general audiences, they never interrupt a drawing in progress, and there are no rewarded ads and no in-app purchases.
