OctoPulse: OctoPrint Companion

Your OctoPrint in your pocket. Monitor, control and print from your Android phone — no account needed.

OctoPulse is the free, privacy-first companion for OctoPrint. Check progress, watch the camera, and manage prints anywhere on your Wi-Fi. Works with OctoPi, Ender 3, Prusa, Bambu (with OctoPrint), and any printer running OctoPrint.

WHY OCTOPULSE?
• Free & open source — no subscription, no cloud. Data stays between your phone and your printer.
• Made for makers — fast, modern, and built for real print farms and hobby setups.
• Respectful ads — small banner + occasional interstitial after setup. Never during a print.

KEY FEATURES
🔍 AUTO-DISCOVERY — Finds OctoPrint on your Wi-Fi in seconds via mDNS/Bonjour, SSDP and smart subnet scan. No typing IP addresses. Strict OctoPrint verification so only real printers show up.
⚡ 1-TAP PAIRING — Connects using official Application Keys. Just tap your printer → Approve in OctoPrint → done. No API keys to copy.
📊 DASHBOARD AT A GLANCE — See all printers in one place: status, progress %, time remaining, nozzle & bed temps. Pull to refresh.
📷 LIVE CAMERA — MJPEG/snapshot streaming with flip, rotate and auto-reconnect. Keep an eye on first layers from the couch or workshop.
🎛️ FULL CONTROL — Jog X/Y/Z, home axes, extrude/retract, set nozzle/bed temps, control fan, emergency stop, and send G-code via terminal.
📐 G-CODE PREVIEW — 2D & 3D layer viewer with pinch-zoom and orbit. Check layers before you print.
📄 FILE MANAGER — Browse OctoPrint files, preview details, start a print or delete.
🔔 SMART ALERTS — Get notified when a print finishes, fails, or hits 25/50/75/90%. Per-printer toggles and background polling. Respects Do Not Disturb.
🌙 POLISHED & PRIVATE — Dark theme, haptics, offline handling. Your hosts, API keys and camera URLs are encrypted on device and never leave your network.

HOW IT WORKS
1) Install OctoPulse and join the same Wi-Fi as your OctoPrint.
2) Tap “Discover Printers on Wi-Fi”, choose yours, tap Pair & Approve in OctoPrint.
3) Monitor progress, watch the camera, pause/stop if needed, and start your next print.

COMPATIBILITY
Works with any printer that runs OctoPrint — including OctoPi on Raspberry Pi. If you can open OctoPrint in your browser, OctoPulse can connect. For remote access, use your VPN/reverse proxy URL (OctoPrint must be reachable).

PRIVACY FIRST
• No account, no sign-up.
• Print files, G-code and camera feeds never go to our servers.
• API keys stored encrypted with Android Keystore.
• No precise location — discovery scans your local subnet only.
