Big or Small is a calm, picture-based brain game for every age. Each day it picks three short activities for the player, reads every question aloud, and shows nothing but the pictures to choose from. It began as a concept game for young children, including children with language delays. The same gentle games are just as good for school-age players, adults, and older adults who want a pleasant daily routine, including people living with memory changes playing alongside a family member. EIGHT ACTIVITIES, EIGHT LEVELS EACH • Big or Small: which one is big? which one is small? • Biggest or Smallest: compare a whole row • Where Is It?: above, below, left, right, and "not" • Colour Order: remember the colours, then tap them back (backwards at the top levels) • What's Missing?: study the pictures, then find the one that disappeared • More or Fewer: which group has more? • Odd One Out: spot the one that's different • What Comes Next?: finish the pattern Levels adapt to each player, step by step, with an advanced tier for when it gets easy. MADE TO FEEL EASY • An empty screen with only the pictures: no clutter, no countdown • Every question is spoken; tap the screen to hear it again • 111 friendly pictures of everyday things: animals, food, toys, clothes, the weather and more • A gentle hint after a miss; the answer is shown, never scolded • Large text and targets, VoiceOver support, light and dark mode • Use the best voice on the device, or a family member's Personal Voice REWARDS THAT MOTIVATE • A token board fills as you play: tokens for getting it right, and for trying again • Spend tokens on sticker albums, avatars and play backgrounds • Grown-ups can set a real reward to save up for, like a trip to the park • No random rewards, no ads, nothing to buy inside the app PROGRESS FOR GROWN-UPS • A 24-question check-up you can repeat to see progress over time • Reports for 7, 30 or 90 days: accuracy by skill, response time, practice routine and the best time of day to play • Plain-language notes on strengths and what to practise next • Share a PDF report, or export every answer as a spreadsheet • Several players on one device, each with their own settings PRIVATE BY DESIGN No account, no sign-up, no ads and no tracking. Everything stays on your device and works offline. Big or Small is a practice and enjoyment app. It does not diagnose, treat or prevent any condition and is not a substitute for professional advice.
