MoodKnob turns daily mood tracking into a single tactile gesture: spin the rotary dial to set your feeling from 1 to 10. No long forms, no checklists, no accounts — just a big colorful knob, a few emotion tags, and a quick note if you want one. Most mood journals feel like a chore. MoodKnob feels like turning a volume dial. The color shifts from cool blue at the low end to warm red at the high end, with a soft haptic tick at every step so your finger knows exactly where the dial is. Log a mood in under five seconds. Key features: • Rotary knob mechanic — a large, draggable dial from 1 to 10. The color shifts blue → green → yellow → orange → red as you spin upward. • Haptic feedback — a gentle tick at every value change so the dial feels like a physical knob. • Emotion tags — pick from Anxious, Calm, Excited, Sad, Angry, Grateful to add context to the number. • Optional note — drop in a short line about what triggered the feeling. Never required. • Weekly trend chart — a Swift Charts line graph showing your daily mood average for the last seven days, with color-coded dots that match each day's score. • Per-day bar summary — see which days were high and which were low at a glance. • Full history — every entry sorted by date, with swipe-to-delete. • Daily reminder — optional local notification at a time you pick. No push servers, no accounts. • Default knob value — set the dial to open at your typical mood so you log faster. • Wipe data anytime — one tap clears the whole history. Privacy by design: MoodKnob collects nothing. No analytics, no ads, no tracking, no account, no cloud. All entries live on your device via SwiftData. The daily reminder is scheduled locally by iOS. The app never makes a network call. MoodKnob is for you if: • You want a mood tracker you'll actually open every day. • You're tired of long mood journal forms. • You want a tactile, joyful logging gesture instead of a list of checkboxes. • You care about a small, beautiful app that respects your time and your data.
