Use the web app when you want nothing to install, a desktop app when you spend most of the day in the tool, and a phone app for the decisions that cannot wait for a desk. In Kavanah these are not three products: every app opens the same workspace with the same permissions, so the choice is about the job in front of you, not about where your data lives.
1. The Browser: Reach Without Installing
Microsoft's WebView2 documentation frames the trade-off well: web apps give broad reach, native apps give the full power of the platform. The browser is the reach end. Kavanah's web app is the reference every other app is checked against, it is the only place for the client portal and public share links, and it is the answer on Linux and on any machine you do not own. Browsers that support the Push API can deliver notifications once you allow them. On an iPhone, WebKit added web push in iOS 16.4 for web apps added to the Home Screen, which is one reason the native iPhone app exists.
2. The Desktop: For the Hours You Spend in It
A desktop app earns its place when the tool is open all day. On a Mac, Kavanah's app is native SwiftUI: keyboard shortcuts for creating tasks, searching and switching sections, tabs in one window, a menu bar item with your counts and the time tracker, and a Dock badge. On Windows, the beta app gives Kavanah its own window and taskbar icon; it has no push notifications of its own yet, so heavy notification users may prefer the browser there.
3. The Phone: Decisions, Not Deep Work
A phone is for the short loops: answering a message, approving or rejecting what an AI agent parked, replying to an @mention, checking what is due today. Kavanah's iPhone and iPad app is a native beta through TestFlight and its Android app is a signed APK beta; both push for messages, mentions, agent escalations and finished agent replies. The iPhone app adds taking a photo straight into a task and a live voice call with the agent.
4. A Simple Rule of Thumb
Planning a quarter, rearranging a board, building an automation or reading a report: the biggest screen you have, in the desktop app or the browser. Approving, answering and triaging between meetings: the phone. A shared, borrowed or Linux machine: the browser. If a task feels slow on the surface you are using, it is usually a sign you are on the wrong one.
5. What Stays the Same Everywhere
The workspace, the permissions and the AI agent. Every Kavanah app reads and writes the same workspace on Kavanah's servers, so a member sees the same projects on a phone as on a laptop, and the agent runs under the same policies and approvals whichever app you asked it from. Nothing to export, nothing to reconcile.
Most people end up using two of the three: a desktop or browser for the work, and a phone for the decisions. Every app is on the Kavanah download page.
