Building Doseleaf: An Offline-First Medicine Reminder App with Kotlin and Jetpack Compose

Description and use

Doseleaf is an offline‑first Android app that lets users manage medicines, schedule reminders, and keep dose history locally without a backend.

Problem

Managing multiple medicines, schedules, and dose history is complex and often requires a backend, which can be unreliable or unavailable.

Outcome

Doseleaf delivers a robust offline‑first medication reminder system with local persistence, reliable scheduling, and data protection features, while highlighting engineering lessons around persistence, background execution, and data integrity.

Workflow

• Create or edit a medicine record
• Define one or more daily reminder times
• Schedule reminders via AlarmManager
• Receive notification and record dose action (Taken/Skip)
• View dose history and export reports
• Backup or restore data via JSON, CSV, or PDF

Evidence

Medication management can become complicated when someone needs to track multiple medicines, follow different schedules, and maintain a reliable history of doses.

Source

Doseleaf is a native Android application built with Kotlin and Jetpack Compose.

Source

The application uses Android's AlarmManager to request scheduled reminder events.

Source

Doseleaf includes fallback scheduling behaviour, but reminder delivery still requires validation across supported Android versions and physical devices.

Source

The JSON backup includes profiles, medicines, schedules, dose logs, and inventory records.
