Case Study

Trazo

An offline Android app for tasks, habits, daily planning, and focus without accounts, ads, or a network connection.

Offline productivity with a notebook-inspired interface.

Today and Planner

Daily view, agenda, weekly planner, and monthly calendar for actionable context.

Focus and alerts

Configurable Pomodoro, alerts center, morning routine, and end-of-day schedule.

Local privacy

No accounts, ads, analytics, or network: tasks, habits, and backups stay on device.

Personal information is fragmented, and every tool understands only one part.

Projects, tasks, habits, calendars, and money usually live apart. Rebuilding that context manually becomes a prerequisite for deciding what to do, postpone, or address.

A offline productivity app that connects facts before suggesting actions.

Trazo maintains an auditable local state and turns it into a daily plan, decision radar, daily planning, planner, focus sessions, and configurable reminders. Everything stays local without accounts.

Local data stays private by design.

Context

Connect the entire system

Projects, actions, habits, events, notes, transactions, and inventory share relationships.

Operations

Confirm before writing

Proposals are edited, validated, and applied as a complete batch, with inverse operations for undo.

Privacy

Local-first by design

No account, cloud, or telemetry; JSON backups and Android restricted to local addresses.

A useful productivity app needs clarity more than noise.

Separating interpretation, calculation, and execution prevents a convincing answer from being mistaken for a fact. Trust comes from visible evidence, explicit confirmation, and reversibility.

Version 3.4.0

The current release includes an alerts center, morning and evening routines, measurable habits, widgets, JSON portability, and an alerts center, morning/evening routines, recoverable reminders, and unit tests for streaks.
