SlumberFlow is a calm, screen-friendly sleep journal. Log when you went to bed, when you woke up, and how rested you feel, the app quietly turns those entries into weekly patterns you can actually act on. No sensors, no wearables, no anxiety-inducing scores, just an honest picture of your rest in a design made for late-night eyes. Add notes about caffeine, stress, or exercise to spot what really moves your sleep, follow gentle streaks for consistency, and review monthly trends when you want the bigger picture. Fully offline with a warm dark theme that is easy on tired eyes. If you have ever felt tired but could not say why, SlumberFlow gives you the quiet data to find out.
