Native tools for iOS and Android, engineered to stay out of your way.

Each app is built on its platform's own toolkits, so it launches quickly, feels at home and honors system features such as accessibility settings, dynamic text sizes and dark mode.

When an app needs a cloud service, it connects directly from your device to the provider you choose, using your own key. We run no servers in the middle, require no account, and never sell what passes through.

We earn revenue from software, not attention. Our apps ship without advertising SDKs or third-party trackers, and we do not sell or share personal data.

Narrow scope, careful engineering and steady updates. We would rather ship one tool that lasts for years than ten that are abandoned.

Live subtitles work out of the box with your own speech-recognition key. You pay your provider directly for what you use; Ternframe takes no cut and adds no markup.

An optional upgrade unlocks advanced caption styles, context-aware translation, subtitle export and multi-tab sessions. Available as a one-time purchase or an annual plan.

Apps are distributed through the Apple App Store and Google Play, where purchases are handled by Apple and Google. Where direct purchase is offered on the web, payments are processed by Stripe.
