Tango vs Tango

Hi, I'm AJ. After 13 years making video games, I got laid off and started learning Japanese to make myself more hireable. I couldn't find a flashcard app that wasn't a subscription trap, so I built the one I wished existed. Tango is just me, one indie developer, and every feature exists because I needed it myself. Tango turns your daily screen time into Japanese vocabulary. Instead of scrolling through nothing, swipe through words. Know it — swipe right. Don't — it comes back until you do. No lessons. No grammar drills. No guilt about missing a day. No setup — open it and go. Just words, a swipe, and a system that quietly makes sure the hard ones keep coming back. Learn hiragana, katakana, and essential JLPT N5/N4 vocabulary through quick swipe-based sessions TAP TO REVEAL. SWIPE TO LEARN. Each card shows a Japanese word in kana. Tap to flip and reveal the romaji, English meaning, and part of speech. Swipe right if you know it, left if you don't. Words you miss return automatically — sooner if you keep missing them, less often as they start to stick. FREE TO START 100+ words across JLPT N5 beginner vocabulary Hiragana and katakana, filter by length, nouns, verbs, adjectives or expressions Characters & Particles practice Daily streak tracking Audio pronunciation for every word UNLOCK EVERYTHING — one-time purchase 626 additional words through JLPT N4 Review Mode — drill the words you keep missing All future word packs included One payment. No subscription. Ever. Support for a solo dev Tango works in the gaps — waiting for coffee, commuting, winding down before bed. A few minutes of Japanese practice a day adds up faster than you think.

Tango shows you what is actually behind the thing you were about to scroll past. See a post worth more than a swipe? Screenshot it, hit share, pick Tango. It reads the image, pulls out what is really going on in it, and asks you one question to check you took it in. A fashion reel becomes a garment supply chain. A skate clip becomes Newton's laws. A protest becomes the economics underneath it. The point is that it is about the thing in front of you, not a general knowledge quiz served at a random moment. HOW IT WORKS Screenshot the post. Share it to Tango. Read what it found, answer the question, get on with your day. It takes about a minute. Tango annotates what is genuinely visible in the image and attaches a real, checkable fact to each thing it points at. Then one question, answerable only from what it just showed you, with a written explanation either way. THE PAUSE, WHEN YOU WANT IT You can also just open Tango. A slow breathing cycle, then one question across four kinds of thinking: logic, verbal reasoning, numeric sense, and attention to detail. Useful when you feel the pull of the feed and want a moment before you give in to it. A RECORD THAT IS YOURS A day streak, your accuracy, a seven day history, and a score in each of the four areas. It lives on your phone and belongs to you. No one else ever sees it. ABOUT YOUR DATA The image you share is sent to be analysed and is never stored, never logged, and never used to train anything. Nothing is attached to it: no account, no sign in, no device identifier, no history. Tango cannot see your photo library and never takes a screenshot by itself. It only ever sees the one image you deliberately hand it. Your streak, your scores, and every answer you have given never leave the phone at all. Erase all of it any time from the About screen. WHAT TANGO DOES NOT DO Tango does not watch your screen, monitor other apps, or interrupt you. Everything it does starts with you choosing to hand it something. That is a design decision, not a limitation.
