Duralinga Business French

Duralinga is a mobile-first product for learning practical and business French inside a Telegram mini app. The product takes the speed and habit mechanics people expect from language apps, then removes the noise: no built-in ads, no bloated lesson ceremony, and no feeling that progress is being interrupted every few taps

The design direction intentionally feels sharper than a classroom product. It uses a high-contrast interface, chunky answer controls, short missions, and a visible progress companion so daily French practice can feel closer to a game without losing the seriousness of workplace vocabulary

Most language apps are good at habit formation but weak at professional relevance. Business users often need phrases for meetings, travel, handoffs, hiring, product work, and daily coordination, yet they still get pushed through generic vocabulary, slow onboarding, and ad-heavy monetization

The opportunity was to build a leaner product for people who want practical French fast: Telegram-native, mobile-first, instantly accessible, and structured around useful repetition instead of long content funnels

The product was shaped as a complete learning loop first: pick a level, practice in short bursts, recover weak words, switch into dialogue, and see the day’s mission move forward

From there I designed the interface system, the mode structure, the reward moments, and Jacques as a companion layer that makes progress feel alive without covering the actual task

The main product bet was to make repetition feel less like homework. Duralinga uses small missions, streak pressure, hearts, level gates, and Jacques bond progress to give every session a visible reason to continue

The second bet was trust. The product is ad-free by design, so monetization sits around premium access and levels rather than interrupting practice. That keeps the core loop focused and makes the app feel more respectful than a typical free language product

The learning experience is split into several modes so the same vocabulary can be approached from recognition, recall, sentence construction, and conversation

Jacques was designed as a compact character system rather than a decorative mascot. He reacts, nudges, celebrates, tracks bond progress, and gives the app a recognizable emotional layer

That layer matters because language learning is repetitive by nature. The character gives repetition a little personality, while the UI still stays fast enough for serious daily practice

The result is a focused, gamified business French trainer that feels closer to a premium mini game than a generic lesson feed

This case shows how I can combine product strategy, interaction design, gamification, character design, and performance-conscious mobile UI into one launchable consumer product. The live product can be explored at artemov.app/apps/french
