Clockly review
A feature-rich open-source alarm app for Android, with smart wake, sleep tools, and integrations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Clockly is an open-source Android alarm-clock app for people who want more than recurring wake-up alerts. It combines date-specific and repeat-day alarms with dismissal challenges, sleep tools, countdown timers, and smartwatch features. The challenge options—math, movement, typing, and scanning—let users make alarms harder to dismiss casually. For someone who wants configurable alarms and related clock utilities in one app, that breadth is the main draw; someone seeking only a simple alarm may prefer a narrower app.
Its standout feature is the combination of smart wake and dismissal challenges. A smart alarm can fire early within an optimal window, while Sonar sleep tracking and bedtime tools add sleep-related functions. Multiple concurrent countdown timers support uses beyond waking, and alarm backup and restore address preserving alarm settings. The feature set is oriented toward personal use on Android rather than a broader team or desktop workflow. Wear OS support adds a next-alarm tile and watch-face complications, while Spotify alarm sounds and Philips Hue sunrise lighting extend the wake-up routine beyond the phone.
Integration options include Spotify, Philips Hue, Tasker, and Health Connect, giving Clockly connections across audio, lighting, automation, and health data. It is identified as open source, with release APKs provided; the published information does not establish a paid-plan structure, so this review focuses on its stated open-source offering rather than tier comparisons. One practical caution is the repository's inconsistent naming: it is named Clockly but its README also uses AlarmClockXtreme and identifies the project as a fork. Choose it if open-source status, challenges, sleep tools, and integrations matter; consider another option if consistent product branding or a basic alarm-only experience is the priority.
