Jittergraph: Caffeine Log

JITTERGRAPH: CAFFEINE & SLEEP TRACKER Jittergraph helps you log caffeine, track weekly trends, and understand how your drinks may relate to your sleep. Instead of guessing whether an afternoon coffee affects your rest, you can compare your intake and sleep records in one private, offline app. HOW IT WORKS Log a drink in seconds using six presets: * Espresso * Drip Brew * Green Tea * Black Tea * Red Bull * Monster You can also create custom drinks with your own name, caffeine amount, volume, time, and notes. Entries can be backdated when you forget to log them immediately. Every drink appears in your daily intake feed with its timestamp, volume, caffeine content, and notes. Edit your records or delete entries whenever needed. WEEKLY CAFFEINE TRENDS An interactive seven-day bar chart shows how much caffeine you consumed each day and calculates your weekly average. Tap a day to review its complete intake history. A daily progress ring compares your intake with your chosen limit, helping you see how much caffeine you have logged before adding another drink. TRACK YOUR SLEEP Record your sleep duration, rate its quality from one to five stars, and add notes about falling asleep, waking during the night, or how rested you felt. Jittergraph places sleep ratings alongside your caffeine chart, making it easier to notice possible patterns between intake, timing, duration, and rest. WHY YOU’LL LOVE IT * Fast caffeine logging with six presets * Custom drinks with caffeine and volume values * Backdated entries for missed logs * Daily intake feed with timestamps and notes * Seven-day caffeine chart and weekly average * Adjustable daily intake limit * Sleep duration and quality tracking * Visual caffeine-and-sleep timeline * Pattern insights based on your recent records * Easy editing and deletion UNDERSTAND YOUR OWN PATTERNS Caffeine affects people differently. Total intake may matter, but timing, tolerance, routine, and individual sensitivity can also influence sleep. By consistently logging both caffeine and rest, you can test practical questions: Do late drinks coincide with worse sleep? Does a lower intake improve your rating? Does timing matter more than the total amount? Jittergraph highlights associations in your records, but it does not prove that caffeine caused a particular sleep result. 100% PRIVATE, 100% OFFLINE No account, sign-in, cloud sync, ads, analytics, tracking, or internet connection is required. Your caffeine records, sleep ratings, and personal notes stay stored locally on your device and never leave your phone. Log consistently. Find your patterns. Make better-informed choices.
