• Audio is built in. Tap any phrase to hear it in a native voice — pre-recorded and cached, so it just works offline, no setup. (The voice bar can still pick a phone voice as a backup.)
• Phrases — drilled by situation: cabin restaurants, tea stalls, directions, the tram. Hit play, then say it back out loud.
• Sounds — the Bengali alphabet, tap to hear every letter. Ten minutes here pays off the most.
• Customs — the unspoken rules. This is where tourists actually give themselves away.
• Practice — hear / read / recall / speak. Use it on the plane.

Right thing, right moment.

Tap a chip to jump to a scene — or just search. Common holds the go-anywhere basics (hello, thanks, where's the toilet); a few phrases like drinks live under more than one scene.

You can type in either language — both sides are searched.

• Hundred fuses with a leading "one"; thousand doesn't. একশ (100) already has the "one" built in, but exactly 1,000 needs it said separately: এক হাজার, never a bare হাজার.
• The real pivot is the lakh, not the million. Indian counting groups big numbers at 1,00,000 (লাখ) and 1,00,00,000 (কোটি) rather than the Western thousand/million/billion — a price of ₹5,00,000 is said as পাঁচ লাখ ("five lakh"), not "five hundred thousand".
• Every number from 11 to 99 is its own word. Bengali doesn't build these by stacking a ten and a one the way English does — একুশ (21) doesn't sound like কুড়ি (20) plus এক (1) at all. This kit gives you the round tens as building blocks; treat anything in between as a word to look up, not construct.
• No linking word between a place value and what follows. Numbers are simply placed next to each other — একশ পঁচিশ (125) is literally "hundred twenty-five" with no Bengali word for "and" in between.
• Bengali has its own digits and its own comma spacing. Prices are sometimes printed in Bengali-Indic numerals (০ ১ ২ ৩ ৪ ৫ ৬ ৭ ৮ ৯) rather than 0–9, and big numbers are grouped the Indian way — 100,000 is written 1,00,000, not 100,000.
