Uncaf: Quit Caffeine Tracker
Beat Brain Fog & Cravings
Only for iPhone
Free · In‑App Purchases
iPhone
Try every feature free for 7 days. Understand your caffeine withdrawal through 5 science-backed recovery phases.
Quit caffeine without guessing your symptoms.
Uncaf helps you understand withdrawal phases with science, not willpower.
Know what's happening in your brain — and what comes next.
5 RECOVERY PHASES
Detox > Peak Reset > Stabilization > Rewiring > Freedom
Each phase explains the neuroscience behind your symptoms: why you get headaches (adenosine receptor upregulation), why you feel foggy (dopamine pathway adjustment), and when it gets better (it does).
DAILY CHECK-IN
Log your mood, energy, and sleep quality in under 2 minutes. Over time, you'll see clear trends showing your recovery progress.
CRISIS TOOLS
When cravings hit, Uncaf responds instantly:
- 4-7-8 Breathing Exercise - calm your nervous system in 60 seconds
- Guided meditation and motivation
- Distraction activities
- Urge tracking with trigger analysis
BRAIN FOG GUIDE
Understand why brain fog happens during caffeine withdrawal and get actionable tips to manage it - hydration, movement, sleep strategies, and brain-friendly nutrition.
YOUR JOURNEY
See exactly where you are in your recovery, what's happening in your brain right now, and what the next phase brings. Premium unlocks data-driven personal insights.
WEEKLY SUMMARY (Premium)
