Trellis is a habit tracker built around one idea: real life has rest days, busy weeks, and schedules more interesting than "every day." Trellis is designed to understand them — so your streaks, stats, and reminders finally match how you actually live. STREAKS THAT UNDERSTAND REAL LIFE The streak engine knows your schedule: a rest day never breaks a streak, today isn't "missed" while it's still pending, and skips can excuse a day. A 26-week heatmap and 12-week trends show the long game. ON-DEVICE INSIGHTS Your best and worst weekdays, habits at risk, and habit correlations — like "on days you meditate, you're more likely to exercise." Computed entirely on your device; nothing ever leaves it. FLEXIBLE SCHEDULES Daily, specific weekdays, N times per week, every N days, or N times a month. Check-off habits or quantity goals like 8 glasses of water. Log today — or catch up on the past week. SMART REMINDERS Per-habit reminders with quiet hours, skip-when-done, streak-risk rescues before a streak breaks, and a Monday summary. No reminder spam. SIRI & SHORTCUTS "Mark Meditation done." "How are my habits today?" Log and review by voice, from Spotlight, or with Shortcuts automations. WIDGETS EVERYWHERE Home screen, lock screen, and Mac desktop widgets with one-tap logging — the ring updates without opening the app. PRIVATE BY DESIGN No account. No server of ours. No analytics. Your data syncs through your personal iCloud and can lock behind Face ID / Touch ID. One app for iPhone, iPad, and Mac — built natively for each.

About

Head Pain Barometer

Features
Read full description

Head Pain Barometer shows an anonymous, real-time "pulse" of head pain around you — and the local environmental conditions that people often connect with it. NOW • See the share of people nearby who currently report head pain, and the average intensity. • Switch between "Nearby" and "All" to compare your area with everyone. • Watch the atmospheric pressure and its 3-hour trend. • Tap "It hurts" or "No pain" in a second to add your anonymous signal. ENVIRONMENT • Air quality (European AQI, PM2.5, PM10, NO₂, O₃). • Today's weather and a 48-hour pressure outlook that highlights upcoming drops. • UV index and pollen (birch, grasses, ragweed). PRIVATE BY DESIGN • No account, no sign-up. • Your location is reduced to a coarse area on your device — precise coordinates are never stored. • Anonymous check-ins auto-delete after about 90 days. • No ads. We never sell your data. Head Pain Barometer provides environmental information and anonymous community statistics. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Available in English, Russian and German.
