This application works extremely well when used in conjunction with this device. I can view the data on my phone and synchronize it to the log page as well as generate charts. It's very useful. ### ⭐⭐⭐⭐⭐ Great compact device! *by W***D on April 2, 2026* As a respiratory therapist, I've used a number of peak flow meters- this one is amazing and great for home use. Small, easy to use and no moving parts. It's easily cleaned and stored, with an easy to read screen. Perfect for travel and carrying to work or school. ### ⭐⭐⭐⭐ Great for the Price *by N***E on December 18, 2025* My doctor recommended I get a peak flow monitor due to my asthma issues. This monitor works great for the price. It beeps kind of loudly when you turn it on and it beeps when it automatically turns off. Unfortunately you can’t turn it off with the power button (it only turns the device on) but since it shuts off automatically after not using, there’s no issues with battery life. You can set up the device phone app to feed into your Apple health data which is great. ## Frequently Bought Together - Digital Peak Flow Meter,Home Medical with Tracking Software Manually Recording-Accurate & Reliable Spirometer for Asthma COPD Adult Kids - Zacurate Pro Series 500DL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Silicone Cover, Batteries and Lanyard (Royal Black) - Willnice Training Device, Daily Exercise Device, Natural Trainer for Better Strengthen, Easy to Use and Clean, Standard --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/430258112-digital-peak-flow-meter-home-medical-with-tracking-software-manually](https://www.desertcart.co.uk/products/430258112-digital-peak-flow-meter-home-medical-with-tracking-software-manually) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-04*
