About

ChessP2P

Chess. Offline. Anywhere. ChessP2P is the chess app that works when nothing else does โ€” on a plane, in a tunnel, deep in the basement, halfway up a mountain. Two iPhones pair directly over Bluetooth or peer-to-peer Wi-Fi. No internet, no accounts, no ads. Just open and play. What's in the free tier: - Pass-and-play โ€” two players, one phone. Board auto-flips after each move. - Peer-to-peer โ€” pair two iPhones over Bluetooth or Wi-Fi with one tap. - Full chess rules, including castling, en passant, and promotion. - Chess clocks โ€” 5+0, 10+0, 15+10, 30+0, or untimed. - Draw offers, resignation, claim draw. - Move history with replay. - Saved games โ€” pick up where you left off if you get disconnected. - No accounts. No login. No tracking. No ads. No nags. How it works: 1. Open ChessP2P on both phones. 2. One taps Host, the other taps Join. Connect over Bluetooth or local Wi-Fi. 3. Play. Moves sync instantly between devices. That's the whole onboarding. If you've ever spent five minutes trying to play chess on a plane and watched every "offline" chess app demand a connection, this is the app you wanted. Built for real offline. ChessP2P uses Apple's MultipeerConnectivity โ€” direct device-to-device. No servers. No router. No Wi-Fi network required. The two phones find each other directly, even in airplane mode (just keep Bluetooth on). If a peer drops out, the game is saved on both sides. Reconnect and it picks up where it left off. Free, with optional premium. The full chess experience above is free, with no ads. A one-time premium unlock will add board and piece themes, expanded clock presets, multiple concurrent games, and post-game analysis. Pay once, unlock for life โ€” no subscriptions. When you play a friend in a P2P session, your premium features extend to them for the duration of the game; they never have to pay to play with you. Perfect for flights and airplane mode, subway commutes, cafรฉs where the Wi-Fi is "ask the bartender," camping trips, festivals, and casual games between friends, parents and kids, or anyone learning the game. Built offline, on purpose.

Verdict

The call

The clearest difference is ads: ChessP2P at none against Proper Sudoku's shown. ChessP2P also leads on update cadence (fortnightly vs every 10 months). Proper Sudoku's advantage is iOS requirement (15.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
