Connects with new PECOAir and PECOAir+ purifiers, Glow Humidifier, and legacy Air, Air Mini, Air Mini+, and Air Pro purifiers. LOCATION MANAGEMENT Monitor your air quality by room or by property, wherever you are. If you’ve got a Molekule purifier there, you’ve got a reading. KNOW WHAT'S IN YOUR AIR Fast readings from PECOAir's sensor suite: fine particles (PM2.5 and PM10), VOCs, humidity, and temperature. Indoor readings alongside outdoor conditions, so you always have context. TRENDS THAT MEAN SOMETHING Get notified when pollutant levels rise, and see what triggered the spike. Look back by day, week, or month to see what's really shaping your air, from cooking and cleaning to pollen and wildfire smoke. NEVER MISS A FILTER CHANGE See how much life your filter has left and get notified when it's time for a replacement, so your purifier keeps performing at its best.

Measure every run on your dog's treadmill. Firepaw reads a Bluetooth speed sensor on the treadmill's roller and shows your dog's speed and distance live, and whether they're walking, trotting or running. Then it keeps the whole story: history, progress, goals and personal bests. Made for owners, trainers, canine rehab professionals and competition organizers who work dogs on slatmills and carpet mills. LIVE SESSIONS • Live speed, distance and time, and whether your dog is walking, trotting or running • The clock starts on your dog's first step, not while you're still getting them on the belt • Keeps recording when you switch apps or lock the screen • Run several dogs at once, each on its own treadmill with its own sensor INSIGHTS AFTER EVERY RUN • A plain-language summary: how long your dog walked, trotted and ran, and how often they stopped • Speed chart with walk, trot and run zones and the session average • Longest stretch, best 60 seconds, and estimated energy burned once you've added your dog's weight PROGRESS OVER TIME • Every session, day by day • Weekly distance chart, trends and training streaks • Personal bests: longest distance, longest session, fastest minute, biggest week • Weekly distance goals with a progress ring DOG PROFILES • Breed, age, fitness level, health notes and training goals • Weight tracked over time on a simple chart SHARE WITH YOUR TEAM • Give co-owners, trainers or vets access to a dog, each at the level they need • Let access expire on a date, or keep older sessions private • Hand a dog's profile over to its owner with a one-time code COMPETITIONS • Timed runs that start on the dog's first step and stop themselves • Rank dogs by distance or top speed; each dog's best run counts • Enter any dog by name: competitors don't need the app • Continue a competition on another phone, and share or save the results as a PDF WORKS ANYWHERE • No signal at the barn or the venue? Everything is saved on your phone and uploads when you're back online • Kilometers or miles, kilograms or pounds • No ads and no third-party analytics WHAT YOU NEED • A dog treadmill: a slatmill or carpet mill • A standard Bluetooth cycling speed sensor on the treadmill's roller, set to speed mode. Firepaw is built and tested with the Coospo BK9S • A one-time calibration: enter your roller's diameter • A Firepaw account
