HashWatch is the fastest, BEST way to monitor and tune Braiins OS Miners, Bitaxe/NerdQaxe++ Solo Miners and Canaan Miners. (Bitmain Devices like Antminer S21+, S21+ Hyd, S21 Hyd, S21 Pro, S21 XP, S19 series, Canaan Avalon Q, Mini Nano3 and Nano3s, Braiins firmware devices like BMM101 or devices flashed with their firmware. Also supported are Luxos devices!) No more filling your Home Screen with IP based shortcuts. Hashwatcher gives you a Birds Eye view of your entire mining operation. All of your devices visible on one screen!

-Overclocking for Solo Miners
-Fan speed control for all Canaan miners. Never before been done.
•Bold, Real-Time Visibility
See true hashrate (TH/s), power (kW), temps (°C), and efficiency (W/Ths) at a glance.

•Birds-Eye Fleet View
Track total hashpower, average temps, and power across all rigs, with status indicators and uptime.

•Miner Detail Dashboards
Rich charts and metrics designed for quick troubleshooting and daily operations.

Ratings and reviews

Amazing app, if you have a Nano3s you will need this as their is no fan control on the app itself. I'm having some issues with connectivity, especially after setting up the hub, but think it's me . some days I can get all miners to show, some days I'm lucky to get one. As most apps now, I don't feel like this is made for Android, have a Samsung S26 Ultra and have to force stop the app alot. will say the devs are amazing, always listening. sent an email about the hub, was contacted in minutes.

great app for keeping an eye on your miners however since the last update the automatic fan/temperature control has stopped working and is stuck on 100%. I've restarted the app, and my miners but still refuses to work.

Great app with all miner data available at a glance. Also pairs well with Tailscale for remote access. Would it be possible in future updates to see more than six miners on one screen without scrolling up and down? Like maybe add a setting for concise view which would shrink the miner windows with only basic data like name, hashrate, temps and efficiency in each one. Tapping a window would anyway bring up detailed data as it does now. Just a suggestion for those who have way more than 6 machines
