One picture,
every language.

Tap a letter and watch it turn into a mango, a cat, a kite — then hear its name in Bangla and English. The picture never changes; only the letters and the voice do. That's how children learn that languages are different names for the same world.

Letter Zoo showing a mango with the word Mango in English

The same mango with the word আম in Bangla

The same mango. Mango in English, আম in Bangla.

Inside the app

Five places to play, no reading needed

Every screen is pictures, big buttons and a friendly voice. A child who can't read yet can use all of it alone.

🌳

Letter Forest

Every letter is a little creature. Tap it: it says its name, turns into its picture, then says the word.

🏖️

Number Beach

Count from 1 to 20. Objects pop in one by one while the voice counts along, then says the number.

🖍️

Paint Hill

Trace letters and numbers with a finger, stroke by stroke, in the right order. Wrong strokes just fade away.

🧩

Puzzle Cave

Letter Jigsaw, Shadow Match and Bubble Pop. A new puzzle loads by itself when one is done.

🦁

My Zoo

Twenty-four animal stickers, earned by playing. Tap one to hear its name in the chosen language.

🌍

The globe

On any letter, tap the globe to hear the same picture named in every language the app knows.

The idea

Switch the language, keep the picture

Most apps teach English letters with one set of pictures and Bangla letters with another. Letter Zoo uses one shared world: the mango that stands for M is the very same mango that stands for আ. Flip the flag on the wooden sign and nothing but the letters and the voice change.

Made for little hands

Nobody loses

No timers, no lives, no buzzers. A wrong move springs gently back; a right one is celebrated.
Buttons are big enough for two-year-old fingers, and there is no text a child has to read.
A friendly owl points the way if a child pauses, then stays quiet.
The voice plays even when the phone is on silent, so the letters are always heard.

Made for parents

Help

Questions parents ask

How do I open the Parent Area?

Tap the lock in the bottom-right corner of the home screen and answer the question for grown-ups (a small multiplication, written in words). There you can choose the languages, set a daily play-time limit, reset stickers and read the privacy policy.

How do I switch between Bangla and English?

Tap a flag on the wooden sign at the top of the home screen. To hide a language from your child, switch it off in the Parent Area.

My child's time is up. How do I give more?

In the Parent Area, under Daily play time, tap Add 15 minutes for today, or change the limit. The count starts again from zero every day.

There is no sound.

Turn the volume up with the side buttons, and check that no Bluetooth headphones or speaker are connected. The voice plays even when the device is on silent.

Will I lose stickers if I update the app?

No. Updates keep everything. Only deleting the app removes stickers and settings, because they are stored on the device and nowhere else.

A letter is pronounced wrongly. Can I tell you?

Please do. Write to ashik.nwu@gmail.com with the letter and what you heard. Every message is read.
