iAlarm (Interval Alarm)

An offline-first Android utility built with Tauri 2, React 19, TypeScript, TailwindCSS v4, Rust, and native Kotlin integration.

Interval Alarm enables users to create a single alarm sequence that automatically schedules multiple occurrences at fixed intervals from a chosen anchor time, without requiring multiple alarms to be configured manually.

Application Name: iAlarm
Full Brand Name: Interval Alarm
Package Identifier: com.intervalalarm.alarm

Key Features

Automated Fixed-Interval Scheduling: Schedules occurrences based on the formula occurrence(n) = start_time + (n * interval).
Multi-Day and Midnight Rollover: Sequences seamlessly traverse midnight and span multiple calendar days.
Recurrence Modes: Supports One-Time, Daily, Selected Weekdays, and Continuous sequence repetition.
Native Android AlarmManager Integration: Alarms are registered as exact alarm clocks via Android's setAlarmClock API, showing the system alarm clock icon and waking the device from Doze mode.
Zero-WebView Background Dependency: Active sequences are mirrored to Android SharedPreferences. If the application process is terminated or the phone reboots, alarms trigger and advance headlessly via native broadcast receivers.
Lock-Screen Full-Screen Intent Presentation: Uses SCREEN_BRIGHT_WAKE_LOCK, ACQUIRE_CAUSES_WAKEUP, and setShowWhenLocked to illuminate the screen and present a dismiss/snooze interface over the keyguard.
Hardware Audio and Device Ringtone Detection: Automatically detects the user's default device alarm ringtone and enforces audible volume on the STREAM_ALARM audio channel.
Isolated Snooze Architecture: Snoozing creates a temporary occurrence without altering the master sequence interval grid.
Downtime and Past-Occurrence Handling: Expired occurrences from system downtime or battery depletion are skipped cleanly, targeting the next valid future occurrence.
Circadian Luxury Interface: Built with TailwindCSS v4 using a dark obsidian palette (#121316), electric lavender accents (#c8bfff), cadence emerald (#40e17e), and tabular digital clock readouts.
