About this app

Changemonitor is a fast, native Android client for changedetection.io, the popular open-source website change detector. Connect the app to your own self-hosted changedetection.io instance and keep every page you care about in your pocket.

Track price drops, restocks, job postings, policy updates, competitor pages, documentation changes, or anything else on the web — and get a push notification the moment something changes.

IMPORTANT: Changemonitor requires your own changedetection.io instance. It's a companion app, not a standalone monitoring service. Just enter your server URL and API key to connect, no account sign-up, no middleman.

WHAT YOU CAN DO
• See all your watches at a glance, with favicons and last-changed times
• Read the full change history for any page
• Compare snapshots with clear, color-coded diffs
• Add, recheck, pause, and delete watches
• Get instant push notifications when a watched page changes
• Tap an alert to jump straight to what changed

BUILT FOR ANDROID
• Polished dark interface with 7 themes, plus Dynamic Color on Android 12+
• Home-screen widgets that keep your watches one glance away (Pro)
• Wear OS companion to check changes from your wrist
• Custom notification sounds so the alerts that matter stand out (Pro)
• Available in 12 languages

YOUR DATA STAYS YOURS
Changemonitor talks directly to the server you control. Your watches, snapshots, and API key live on your own changedetection.io instance, not on our servers.

FREE & PRO
Monitor up to 4 watches for free. Upgrade to Pro for:
• Unlimited watches
• Home-screen widgets
• Custom notification sounds
• Custom favicons

Pro is available as a subscription.
