Gapper scans your calendar and finds every free window between your meetings — then suggests the right activity to fill it, based on how long the gap is and how you're feeling right now. WHAT GAPPER DOES: Every day is full of hidden time. The 20 minutes before your afternoon call. The gap between your morning standup and lunch. Gapper surfaces these windows automatically and turns them into opportunities. HOW IT WORKS: 1. Connect your calendar (Apple) 2. Gapper detects free gaps within your work hours 3. Browse activity suggestions matched to each gap's length and your energy level 4. Tap to schedule — it appears on your timeline instantly SMART SUGGESTIONS: Gapper considers three things when suggesting activities: · Gap length — a 5-minute gap gets a breathing exercise, not a 30-minute workout · Your energy level — low energy? We'll suggest a podcast. High energy? Let's move. · Your preferences — enable only the categories you care about ACTIVITY CATEGORIES: · Health — stretching, breathing, quick workouts, meditation · Learning — reading, flashcards, language practice, podcasts · Productivity — journaling, planning, email cleanup, quick reviews You can also add your own custom activities with your preferred duration and energy level. YOUR TIME, YOUR RULES: Set your own work hours so Gapper only looks for gaps between, say, 9 AM and 6 PM — never suggesting you fill time at midnight. WEEKLY STATS: See how much time you reclaimed each week, your current streak, and a breakdown by category. Small wins add up. PRIVACY FIRST: Everything stays on your device. No account required. No data collected. Your calendar data never leaves your phone.
