About this app

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
-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.

•Performance Controls
Set hashrate and power targets directly from the app for supported Braiins OS miners. Custom overclock settings let you dial in your bitaxe for higher hash rate.

Get notified when chip temps exceed your threshold so you can act before problems escalate.

•Maintenance Tools
Plan service, export daily PDF reports, and keep clean records for auditing and team handoffs.

Ratings and reviews

Great consolidate dashboard. My only complaint is that apparently the latest builds are not available though the store. I'm unable to get the chances per month to populate and when I did research it said that I needed to upgrade from 1.0.9, which is all the available, to 1.4.5. If version 1.4.5 is supposedly out there I'm questioning why 1.0.9 is all that's available on Google Play.

Great app for mining farm. I can see all stats and have full control over my operation. I have purchased the lifetime subscription to help support a good product. I thank the devs for the hard work put into the app. Looking forward to future enhancements.

It's about time someone finally steps up to the plate and gives this community the #1 thing we've all been waiting and asking for. This app is very easy to use, and it's intuitive; First time launching, and it was like I've been using it my whole life. It's that simple, and I can't wait to see what future development brings us. i know it's still new, so there isn't much to complain about. But if I do, it's only because over half my miners can't connect to it....YET 😊
