## What it is
Once is a small Android library for managing one-off operations, letting apps track whether an action has already been performed within a given scope such as per install, per app version, or per time interval. It provides a simple tag-based API for marking tasks done, checking pending tasks, and rate-limiting operations.

## Use cases
- show a guided app tour only on first install
- display release notes once per app upgrade
- rate-limit phoning home to once per hour
- show feature onboarding only after the user has seen basic functionality
- check when a tagged action was last performed

## When to choose
- you need simple first-run or per-version one-time behavior in an Android app
- you want lightweight time-based rate limiting without extra dependencies

## When to avoid
- you need persistent, user-facing task management or scheduling
- your project is not Android or targets API below 14

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk
- domain: mobile-development, android-tools
- platform: -
- tags: android-library, one-off-operations, rate-limiting, first-run, android
