Caerla

Track what you do with your time. Multiple concurrent sessions, custom fields, Apple Calendar sync, lock screen widgets. No ads, no third-party trackers.

Caerla is a quiet journal of your time.

Start a session when you start something — Deep Work, Reading, Gym, time with people who matter. Caerla times it for you. End the session when you're done and it lands in your history.

Annotate the one-shot stuff — Coffee, Water, Medication, Mood — with a single tap.

Every session and annotation is yours, synced privately to your account, and visible the way you'd want to see it: a Today hero with a composition bar, a 7-day chart, and a clean grouped list.

Built for people who want to know where their time goes — without surveillance, ads, or noise.

— Multiple concurrent sessions Up to five sessions running in parallel. Out with family AND walking. Deep Work AND a meeting. Each gets its own Live Activity on the lock screen.

— Custom fields Add structured fields to any activity. Pain check with a 1-10 scale and a list of locations. Medication with a single-select from your meds. Gaming with a "what game" text capture. Any kind that fits how you think.

— Calendar sync Caerla creates a dedicated "Caerla" calendar in your Apple or Google account and writes every session and annotation there. It never reads or modifies your existing calendars. Edits in Caerla propagate. Disconnect with one tap.

— Multi-location waypoints For activities that span multiple places — a long Out With Friends, a trip — Caerla can capture each stop using iOS's privacy-friendly Visit API. Foreground only, opt-in per activity.

— Quick start from your home screen Tap-to-start tiles in a home screen widget. Tap-to-start from your lock screen. One-tap activity launch from Control Center on iOS 18.

— Siri and Shortcuts "Start Deep Work in Caerla." "Log a coffee in Caerla." "End my activity in Caerla." Donations to Siri learn your patterns.

— Open API for developers A documented HTTP API at api.caerla.com/docs. Generate per-key tokens from Settings → Developer. Scripts, automations, your own dashboards.

— Privacy by design No ads. No advertising identifiers. No cross-app tracking. Caerla's PostHog and Sentry SDKs collect product analytics and crash reports tied to your account so we can improve the app and fix bugs — that's it. Full details in the privacy policy. One-tap account deletion in Settings.
