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!) 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

•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

Can you guys fix the bug where i can't duel mine, every time i try it only restarting my device, i got the latest firmware for the gt801 bitaxe but won't let me, i tried force closing, clear cache, i made sure that 2 pools are listed on my miner, i have latest update on this app as well, like what is the trick to make this happen? so aggravating that it doesn't work, it should but doesn't. please help

UPDATE : Really really do not like new layout. please make the fleet cards the first screen that is brought up like it was previously and then an option to goto what you now have as the first screen. ......... PREVIOUS REVIEW :Absolutely awesome and well written program. Wish the free version allowed 4 Nano3s miners as I just can't afford to pay for the premium version at the moment. Well done.

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
