Tombli is a calm little sensory sandbox for children ages 0–5. Every tap and swipe answers with something gentle and delightful — no rules, no menus to get lost in, nothing to fail at.

🎨 What happens when little fingers explore

• Bubbles drift and pop
• Balloons squeak as they inflate, then whoosh away
• Magic stars twinkle, rise, and burst into sparkles
• Slime splats — and friendly monsters wander in to tidy up
• Rangoli patterns bloom in perfect symmetry
• Rainbow ribbons and glittering trails follow a drawing finger
• Alphabet letters say their names, and numbers join the fun
• Fireworks bloom across the night sky

🌸 Seasons change, gently

Snowflakes in winter, cherry-blossom petals in spring, fireflies on summer evenings, drifting leaves in autumn. Grown-ups can pick a season, or turn it all off.

👶 Built for toddlers

Every touch gets an instant, friendly response. Nothing to unlock by accident, nothing to break, and the screen tidies itself after a quiet moment. Sounds are tuned to be soft on little ears. Along the way there's plenty of cause-and-effect, fine motor practice, letters, numbers, and color — but really, it's about wonder.

🛡️ Honest with parents

• Free to try, with a full set of effects and no time limits
• One single purchase unlocks everything — no subscription, and no ads, ever
• Zero data collection: nothing collected, stored, or shared
• Plays fully offline — internet only matters if you choose to unlock
• The optional sound visualizer listens through the microphone so nearby sounds become light — on this device only, never recorded, and only if you turn it on
• All settings sit safely behind a grown-ups gate

👪 Grown-up controls

Choose exactly which effects appear, pick a background, set quiet hours for bedtime, hush every sound instantly, and more. Your choices are remembered.

💛 Made by one dad

Tombli is built by one dad who wanted something gentle for his own kids — no ads, no dark patterns, no racket. Just cause and effect, a bit of wonder, and the occasional slime monster.

It's good for nap wind-downs, waiting rooms, car rides, and those five quiet minutes everyone needs sometimes.

Thank you for trusting me with your child's screen time. I don't take that lightly.
