A language practice app built around spaced repetition and real conversation

Language apps that stick use spaced repetition for vocabulary and real speaking practice to build confidence. Goodspeed generates both in a single build: an SRS flashcard engine, a speaking drill mode, and streak-based motivation, all wired to Supabase and ready for App Store submission.

HOW IT WORKS FOR LANGUAGE PRACTICE

From idea to language practice app in the store

Goodspeed runs a four-stage pipeline: score, plan, build, and ship. For a language practice app the pipeline generates 6 production-ready capabilities specific to this vertical, finished work rather than a shell you have to complete yourself. The backend gets provisioned during the build and Goodspeed operates it after launch, so you open no infrastructure accounts and configure no servers.

Score
Score your language practice idea against sources across the public web: app-store reviews, Reddit threads, search trends, and competitor gaps.
Plan
Generate the full language practice architecture spec, screen map, and data schema specific to your idea's unique angle.
Build
Production-ready TypeScript and React Native code generated on expo, react-native, supabase, with every feature in the spec wired up and tested.
Ship
EAS Build compiles iOS and Android binaries. Goodspeed submits to TestFlight and Play Console, then runs the backend it provisioned during the build (database, auth, analytics), so you open no infrastructure accounts. You own the repo, the signing keys, and the listing.
