ICRM is the ultimate companion app for coffee roasters. Designed to work hand-in-hand with the Croaster roasting device, ICRM gives you real-time visibility into every roast — from green bean to the perfect drop — and keeps a detailed record of every batch you've ever roasted.

Whether you're a specialty roaster perfecting your profiles or a home enthusiast exploring different origins, ICRM puts professional-grade roast control in your pocket.

☕ Real-Time Roast Monitoring
Connect your Croaster device over Wi-Fi or Bluetooth and watch your roast unfold live. Track Bean Temperature (BT), Exhaust Temperature (ET), and their respective Rates of Rise (RoR) — all displayed in clean, dynamic charts and a detailed data table. Keep your screen awake automatically so you never miss a moment.

📊 Roasting Charts & Table View
Visualize your roast curve in a beautifully rendered chart powered by Syncfusion. Switch instantly between Chart View and Table View to inspect individual data points. Review temperature trends across the entire roast at a glance.

🔔 Smart Alarms
Set up intelligent alarms based on roasting events, temperature values, and custom conditions. Each alarm can trigger a pop-up notification, beep sound, a custom audio alert, and even send commands automatically to your Croaster device — so you never miss First Crack again.

🎯 Roasting Events
Log and track every critical roasting milestone: Charge, Turning Point, Dry End, First Crack Start & End, Second Crack Start & End, Drop, and Cool. Customize, reorder, and create your own events to match your workflow.

📝 Roast History
Every roast is automatically saved with full detail — including roast date, batch number, roast profile (Light / Light-Medium / Medium / Medium-Dark / Dark), green bean and roasted bean info (weight, volume, density, moisture), development percentage, total roast duration, notes, and attached photos.

☕ Coffee Library
Build your personal coffee catalog. Store detailed information for each coffee including origin, process, varietals, altitude, supplier, price, and notes — for both single-origin and blends. Attach photos to each entry and manage your collection with ease.

📦 Inventory Management
Track your green coffee stock directly in the app. Assign coffees from your library to inventory entries, set stock quantities with customizable weight units, add SKU codes, and archive entries when no longer needed.

⚡ Custom Commands
Send custom JSON commands directly to your Croaster device. Configure temperature correction, sampling intervals, temperature units, and more. Attach commands to alarms for fully automated roasting workflows. Advanced features include firmware OTA updates and network reset.

🔒 Backup & Restore
Never lose your data. Create manual backups of all your roasting data and import them anytime. Auto-backup keeps your data safe in the background.

🎨 Fully Customizable Appearance
Choose your preferred theme (Light / Dark / System Default), enable OLED Dark Mode for true black backgrounds, and pick a color scheme that suits your style.
