empty is a meditative iOS app for one quiet moment a day. Frosted-glass items drift down from a custom Metal-shader cosmic sky. Tap one to open a hidden message — a small piece of stillness written for the kind of pause most days never make room for. Save it, write a personal journal note on it, breathe with it, and watch your quiet days stack up over time. — SIX UNIVERSES TO SWITCH BETWEEN — Cosmos, Aurora, Ember, Ocean, Void, Sakura. Each is its own GPU-rendered sky with its own colors, motion, falling symbols, and a curated message set written for that mood. Swipe left or right to glide between them. — A LIBRARY THAT REMEMBERS — Every message you open is automatically saved to your personal Library. Search the full text, the author, or your own journal notes. Filter by favorites or by theme. Copy, share, or remove anything any time. — A JOURNAL FOR WHAT THE MESSAGE MADE YOU FEEL — Each saved message has its own free-form note attached. Write a short reflection in the moment of the reveal, or come back later and edit it. Notes are searchable and stay only on your device. — A BREATHING TIMER THAT BREATHES WITH YOU — Four guided modes: Box (4·4·4·4), 4-7-8, Calm (5·5), and Energize (6·2·4·2). The breathing orb expands on inhale and contracts on exhale; haptics tap softly at the end of each cycle. Pick a 1, 3, 5, or 10-minute target. — A STREAK THAT IS NEVER LOUD ABOUT IT — A heat-map calendar of your openings, current streak, longest streak, and a per-theme distribution bar. No leaderboards, no comparison. Just your own quiet days. — OPTIONAL DAILY REMINDER — A single, gentle local notification at a time you choose. No remote payload, no tracking. Toggle off any time. — BUILT WITH STILLNESS — No accounts. No analytics. No third-party SDKs. No servers. Library, journal, history, and breathing log live only on your device. — EMPTY PRO (OPTIONAL, ONE-TIME) — empty is free to download with three openings every day and full access to every other feature — themes, library, journal, breathing, streak, sharing, and reminder. To remove the daily limit on openings you can unlock empty Pro as a one-time, non-consumable lifetime purchase. No subscriptions, no recurring charges. Pricing is shown in your local currency on the in-app purchase screen. Payment is charged to your Apple ID at confirmation of purchase. The Pro unlock can be restored on any device signed in to the same Apple ID via Settings → Restore Purchase. — DESIGNED FOR THE QUIET MINUTES — empty is not a productivity tool. It is not a streak you have to keep. It is a deliberately small ritual. Open one drop today. Or don't. The void is not waiting for you to fill it. one drop. infinite void. LIVE OUTSIDE THE APP • Home Screen, Lock Screen & StandBy widgets with your daily message — tap to draw a new one, no app launch needed • Siri, Spotlight, Shortcuts & Action Button: "Reveal a message in empty" • Control Center control (iOS 18+) • Breathing sessions as a Live Activity on the Lock Screen & Dynamic Island GO DEEPER • Press and hold a falling glyph to charge it — release at full charge for a rare, deeper message curated for each universe ——— Privacy Policy: https://agezgin.github.io/emptyapp-ios/privacy.html Terms of Use (EULA): https://agezgin.github.io/emptyapp-ios/terms.html Support: https://agezgin.github.io/emptyapp-ios/support.html Contact: h.ahmetgezgin@gmail.com

Verdict
The clearest difference is in-app purchases: PETKIT at none against empty's 1. PETKIT also leads on update cadence (fortnightly vs every 3 months) and iOS requirement (14.0 vs 26.4). On price, ads and device support there is nothing between them.
