BrewSpy – Your Central Hub for Digital Fermentation Tracking
BrewSpy is a dedicated fermentation monitoring app that collects data from your digital hydrometers, airlocks, and keg sensors to display real-time fermentation progress. Whether you use an iSpindel, Tilt, PLAATO, or Nautilis device, the app pulls all readings into one clean interface. This tool helps homebrewers track gravity, temperature, and ABV without manual logging, turning raw numbers into actionable insights. It turns a smartphone into a full brewery dashboard.
Seamless Device Integration and Customization
Supporting iSpindel and Tilt hydrometer tracking, plus PLAATO Keg and airlock sensors, the app connects via a webhook relay or Nautilis bridge. You can assign any device as an ambient temperature sensor for another, creating a complete chamber profile. A built-in calibration wizard guides you through setting up your iSpindel for accurate readings. The app also accepts custom data from BrewPiLess or other HTTP logging sources, making it flexible for advanced setups.
For draft system management, the taplist feature links to PLAATO Keg sensors to show remaining beer volume. This turns the app into not just a fermentation tracker but also a keg inventory assistant. You can customize event-based triggers to send notifications or call webhooks, automating actions like turning on a cooling fan or sending a graph to a brewing group.
Graph Visualization and Batch History
Every fermentation creates a live graph of gravity and temperature, which you can compare side by side with previous batches. This homebrew fermentation graphs feature makes it easy to spot trends, stalled fermentation, or temperature spikes. You can save screenshots to your gallery or share them directly with friends. The app records ABV and attenuation at any point, so you know exactly when the beer is ready.
Batch history is stored locally, allowing you to scroll through past brews and review statistics. The interface is clean and uncluttered, with graphs that respond to pinch-to-zoom gestures. Homescreen widgets keep the current gravity and temperature visible without opening the app, useful for quick checks during a brew day.
Real-Time Alerts and Remote Access
Setup requires sending device data to the BrewSpy server, which then pushes updates to your phone. You can create event rules – for example, notify when gravity drops below a certain point or when temperature exceeds a range. These brewery data notifications ensure you never miss a critical change. The app supports webhook URLs, so you can integrate with IoT devices like a heater or chiller for automated corrections.
While the app is free for one device, a subscription unlocks multi-device support and advanced features like cloud backup and extended history. The subscription model is straightforward, and the free tier covers most homebrewers starting out. Overall, the app streamlines the brewing workflow, reducing manual logging and providing a calm, data-driven view of fermentation.
