Evarik

Evarik helps you take control of your home's heating, one room at a time. Map every room across each floor of your home, then log daily readings — temperature, how the room actually felt, and any adjustments you tried. Over time, a clear picture emerges of what works and what does not. Every diary entry captures the full story: the thermometer reading, your comfort rating (cold, draughty, comfortable, or warm), a written note, and an optional photo. Mark whether an adjustment helped, and Evarik automatically surfaces your most effective fixes — no manual tracking required. The Fixes tab turns your diary into a real action plan. See at a glance which adjustments have the best success rate across your rooms, so you spend less time guessing and more time staying comfortable. Season records let you compare heating performance year over year. Designed for homeowners, renters, and landlords who want a simple, offline-first record of their heating seasons. No account or subscription needed — your data stays privately on your device. Supports Celsius and Fahrenheit.
