About

Vistacker

Features
Read full description

**Your terminal task list. Now in your pocket.** Vistacker is the capture layer built for developers. The CLI runs in your terminal with vi-style keybindings and live sync. This app is its iOS companion — the same vaults, the same tasks, always in sync. Add a task on your commute. It's waiting in the TUI when you sit down at your desk. Mark something done from your phone mid-standup. Your terminal already knows. All local first, so it is blazing fast. **Built around the terminal workflow** The Vistacker CLI (`vistacker`) is a full-featured terminal UI — vi keys, stacks, notes, logs, and instant sync over gRPC. This app connects to the same vaults so your work follows you off the keyboard. **What you get** - All your vaults and stacks, exactly as they are in the CLI - Add, reorder, and complete tasks from anywhere - Attach notes and progress logs to any item - Real-time sync — changes land on all devices in under a second - Fully offline — works without a connection, syncs the moment you're back - End-to-end encrypted vaults — your data is encrypted before it ever leaves your device - Vault sharing — collaborate with teammates, with fine-grained owner / read-write / read-only roles - Sign in with Apple, GitHub, or Google — no passwords **Free to start** One vault, unlimited tasks. Upgrade to Pro for up to 50 vaults.
