Alyx: Caffeine Kit

A caffeine tracker with attitude and no accountability

Website itunes.apple.com
Overview

What it is

Alyx helps you log caffeine, visualize its impacts, and see how it affects your sleep. It may help you rethink that third espresso. Or, encourage you to drink several more. There's really no way to know.

Intent

I need it when

Create and track custom drink recipes with accurate caffeine content

Premium users can create custom drinks and use AI to automatically calculate caffeine contents, then save and sync these recipes to iCloud for consistent tracking across devices.

Access caffeine tracking data across multiple Apple devices with automatic syncing

The app stores all data in Apple Health and syncs via iCloud, enabling seamless access on iPhone, iPad, and Mac. Widgets and Siri Shortcuts extend functionality across the Apple ecosystem.

Monitor caffeine consumption patterns over time to identify excessive intake habits

Alyx displays trending data showing whether caffeine consumption is increasing or decreasing, plus a Hall of Fame feature for consumption records. Multiple charts visualize patterns and health impacts, helping users become aware of and adjust excessive habits.

Receive personalized reminders to stop caffeine intake before it disrupts sleep

The app generates a customized 'Last Call' alert each day based on individual caffeine metabolism, allowing users to set alarms so they avoid late-day consumption that would interfere with sleep.

Track daily caffeine consumption and understand its impact on sleep quality

Alyx logs coffee, espresso, energy drinks, and custom beverages, then calculates how much caffeine remains in the body at bedtime and forecasts sleep loss. Users see charts showing caffeine consumption trends and direct correlations with sleep duration via Apple Health integration.

Drop

Not a fit when

  • User needs a caffeine tracker for Android devices; app is iOS-only
  • User wants completely free app with no premium features; premium features require subscription
  • User prefers manual data entry without Apple Health integration; app relies on Apple Health for data storage and syncing
  • User needs real-time caffeine level monitoring beyond 12-hour forecasts; app shows decline over next 12 hours only
  • User requires offline functionality; app depends on iCloud sync and Apple Health ecosystem
