MyCaffeine
A caffeine and hydration tracker for iPhone and Apple Watch. Log custom or branded drinks, understand how caffeine changes through the day, and explore how it relates to your sleep, heart rate and activity.
Description
A native iPhone, Apple Watch and widgets experience built with Swift and SwiftUI.
MyCaffeine turns each drink into a clear picture of your current body caffeine, predicted bedtime level and daily intake. A researched branded catalogue sits alongside your own drinks, while personalised limits, trends and notifications help you make more informed choices. Optional Apple Health integration keeps caffeine, water and nutrition connected with the health data you already use.
Originally built as my final year project at the University of Portsmouth. Read the report here.
