Dialedin: AI Espresso Coach is a mobile application available on iOS and Android that provides AI assisted shot analysis and equipment aware guidance for home baristas. Its primary function is to help users understand what changed during an espresso extraction and offer a practical recommendation for the next adjustment. The app is built around the user’s specific machine, grinder, and coffee, and is designed as a focused companion for learning one’s setup rather than a replacement for tasting, experimenting, or building intuition. The core feature is DialChat, which gathers details that matter for a shot. Users can input shot time, dose, yield, and taste notes, or share a video for automatic timing analysis. The app analyzes this information and produces a recommendation with a confidence level and a plain language reason. Users can select their machine and grinder from a database, or share a photo for identification assistance. Beyond shot analysis, the app offers browsing of machine and grinder information, as well as brewing and cleaning guides. It also includes a guided process that helps users work through dose, yield, timing, and taste one variable at a time, using a practical baseline. Typical use cases involve a home barista preparing a shot, recording its parameters, and receiving a clear next step for improvement. For example, a recommendation might be to move about six small steps coarser from the current setting. The app is useful before, during, and after the shot, as it provides context for the user’s equipment and maintains a history of shots and recommendations. This workflow helps turn a difficult shot into a clear next move and supports building a repeatable routine. The app also addresses maintenance by keeping cleaning and upkeep from becoming a mystery variable. Dialedin is free to start, offering up to three AI assisted shot analyses per month along with access to equipment information and guides. A Pro subscription provides up to 20 analyses per month, keeps shot history and recommendations together, and restores Pro access across devices logged into the same account. The app is designed for home espresso enthusiasts who want to make each subsequent shot more informed than the last.
