Calm Sudoku
Sudoku without the noise. No ads, no accounts, no pressure.
Calm Sudoku is a native iPhone & iPad Sudoku game built around one idea: the puzzle is the product. No ads, no tracking, no accounts, no subscription, no streak guilt — just a beautiful board, a free daily puzzle, and a 300-puzzle library you unlock once for $4.99, forever. Fully offline. App Store privacy label: "Data Not Collected." Really.
Hey Product Hunt! 👋
I'm the maker of Calm Sudoku, and I built it because every Sudoku app I tried felt like it was fighting me for attention — ads between puzzles, streak counters shaming me, "limited time" banners, accounts for a number grid.
Calm Sudoku is the opposite bet: what if a puzzle app just… left you alone?
What's free, forever:
🗓️ A daily puzzle — deterministically picked from the full catalog, so free players get a taste of everything
📚 A 30-puzzle starter library (10 each of Easy, Moderate, Challenging)
🎮 Every single gameplay feature — notes with smart peer cleanup, undo, conflict highlighting, check, reveal, autocheck, fill-all-notes, a reactive number pad with remaining counts. We gate quantity of puzzles, never quality of play.
The one purchase:
💎 $4.99, one time, lifetime. Unlocks the full 300-puzzle library, a 90-day daily archive, and all future puzzles. Family Sharing enabled. No subscription will ever exist.
What will never be in the app:
❌ Ads, tracking, or analytics
❌ Accounts or sign-ins
❌ Lives, currencies, countdowns, or streak pressure (streaks exist only as quiet history stats)
❌ Notification nagging
Nerdy bits, because PH loves nerdy bits 🤓
- 100% offline - single solution guaranteed, difficulty rated by the actual human techniques required
- Native SwiftUI on iOS 18+, SwiftData persistence, StoreKit 2 — no backend of any kind
- Your game auto-saves continuously, so closing the app mid-puzzle just works
- Accessibility is a feature, not a checkbox: VoiceOver, Dynamic Type, Reduce Motion (which gates all celebratory motion and haptics), hardware keyboard support, full light/dark, adaptive iPhone/iPad layouts
The design goal was a warm, paper-like calm — muted colors, spacious controls, restrained motion. The board is dominant; everything else stays quiet.
I'd genuinely love your feedback — especially from folks who've abandoned puzzle apps because of monetization fatigue. What would make this your forever Sudoku app?
Thanks for checking it out! 🙏
