Learn Southern Vietnamese, then find places to use it. Discover events and things to do in Saigon, meet people, and practice the Vietnamese you are learning—all in one app. Every other app teaches Hanoi Vietnamese. But you live in Saigon — or you're heading there. Learn Vietnamese: Saigon is the first app built from the ground up around Southern Vietnamese, the dialect actually spoken by the people around you. This app teaches the Vietnamese you'll hear on the street, in the café, and at the market — not the textbook version that leaves locals confused. WHY SOUTHERN VIETNAMESE MATTERS Most language apps default to Northern (Hanoi) pronunciation and vocabulary. But Ho Chi Minh City and the entire south of Vietnam speak a different dialect — different tones, different pronouns, different everyday words. Learn Northern Vietnamese and use it in Saigon? Locals will understand you, but you won't understand them. We fix that. WHAT'S INSIDE - 50 structured lessons with quizzes covering CEFR levels A1 through B2 - 10,000+ words — 3,000 core vocabulary plus 8,000 in themed word packs - 1,000 sentence flashcards across 50 sets with color-coded grammar highlighting - 6,600+ Southern Vietnamese audio recordings with Southern pronunciation - 6-tone training with visual pitch contours so you hear and see the difference - 475 similar-sounding Vietnamese words across 92 practice sets to sharpen your listening - Smart pronoun system that auto-adjusts anh/em/chị based on your age and gender EXPLORE SAIGON WHILE YOU LEARN See what is happening today and browse upcoming events across Saigon. Find language exchanges, live music, social meetups, and more, with photos, useful details, maps, and links to organizers. Vietnamese-friendly language events appear first to help you find opportunities to meet people and practice. Navigate lessons through an interactive illustrated map of Saigon — not a boring lesson list. Discover vocabulary tied to real places, neighborhoods, and situations. A built-in city guide features 138 curated Saigon venues: cafés, restaurants, markets, and hidden spots locals love. TOOLS THAT ACTUALLY HELP - AI photo import — snap a menu or street sign, create instant flashcards - Study bundled flashcards and audio offline after setup; sign-in, cloud sync and photo import require internet - Apple Watch companion for quick review on your wrist - Color-coded sentence structure shows exactly how Vietnamese grammar works - 5 interface languages: English, French, German, Italian, Korean WHO IS THIS FOR Whether you just arrived in Ho Chi Minh City (HCMC), you're planning your first trip to Vietnam, or you want to reconnect with your Vietnamese heritage — this app meets you where you are.

Verdict
The clearest difference is ads: Learn Vietnamese at none against PolyChat's shown. Learn Vietnamese also leads on update cadence (every 5 days vs every 2 weeks) and device support (4 vs 2). PolyChat's advantage is rating (4.9 vs 4.6) and review sentiment (96% vs 79%). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PolyChat sells 9 in-app purchases, starting at $12.99 per month and Learn Vietnamese sells 12 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
PolyChat holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: PolyChat has 229 ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 96% of PolyChat's written reviews are positive against 79% of Learn Vietnamese's.
PolyChat ships an update every 2 weeks, Learn Vietnamese every 5 days. The most recent releases landed on October 30, 2026 and October 22, 2026 respectively.
