Guides for CoreTalk and CoreCall — what each app does, where to install it, and what it needs before it will work.

Documentation

Two apps, both built around the same idea: the service you depend on should be one you control, not one we put in the middle.

🗣️ CoreTalk

A face-to-face interpreter for one shared phone. Lay it flat between two people and it translates both directions out loud, with the far half of the screen rotated to face them.

📞 CoreCall

A bring-your-own-account dialer. Calls and SMS go through the Twilio or Telnyx account you already own, billed by your provider, with no account of ours in between.

Neither app works out of the box from a store download alone. CoreTalk needs a server and key that it cannot issue you from inside the app; CoreCall needs a telephony account you already have. Both ship a Demo Mode so you can see the interface first. Read the setup page for the one you care about before installing.

CoreTalk

📥 Installation

App Store and Google Play, and the single permission it asks for.

🔑 Setup

Server and key, Manual versus AI auto, session limits, and why a turn sometimes produces nothing.

CoreCall

📥 Installation

Mac App Store and Google Play, plus the platform differences that matter.

🔑 Setup

Connect Twilio or Telnyx, pick a caller ID, place a first call, and the limits.
