Most AI speaking apps send your voice to a server and charge monthly rent. EdgeLingo runs the whole model on your iPhone instead — speech, conversation, and corrections, all on-device. Practice out loud in 9 languages, guided in your native language. Every turn gets a more natural rewrite, and reusable phrases return via spaced repetition. Describe a scene or snap a photo for a custom scenario. Works in airplane mode. One purchase — no account, no subscription, no per-message fees.
