When you tap a node, its full charge is dumped to zero — but a portion spreads to both neighbours in the ring. In Core Four mode, 50% of the dumped charge is distributed. If a neighbour is already close to full, that added charge can push it past 75% (critical) or even 100% (overload). Timing your vents when neighbours are low is the core skill of GridPulse.

GridPulse uses a ramp system: fill rate rises linearly from the start of each session, reaching 2.6× the base speed by the 72-second mark and staying there. This means the first 45 seconds are relatively forgiving, and anything past 90 seconds demands near-perfect timing. The ramp applies equally across all three modes.

Score is: elapsed seconds × 10, plus 5 points per vent (each tap counts). A 60-second run with 40 vents yields 600 + 200 = 800 points. Precision — venting only when necessary — rewards higher survival time, which multiplies the base score far more than rapid tapping. Records are stored locally per mode (Core Four, Relay Five, Array Six), top 10 per mode.

Chain Vent requires you to tap 5 different nodes within any 3-second window during a single session. It is designed for players who have mastered the ring layout and can react quickly across multiple critical nodes simultaneously. The milestone tracks your fastest 5-vent burst automatically — no special setup required. It works across all three grid modes.

GridPulse is fully offline and stores all data locally on your device using iOS UserDefaults. Because nothing is synced to any external server or cloud service, deleting the app also deletes all saved records and milestones. There is no recovery path — this is by design to protect your privacy. Future updates may offer iCloud Backup support.

Open the Settings sheet (tap the sliders icon in the top-right corner of the main menu). At the bottom of the settings, you will find a reset control. Press and hold it for 1.5 seconds — a progress indicator fills as you hold. Release at any point before it completes to cancel. On full completion, all records, milestones, and session stats are wiped. The action is intentionally slow to prevent accidental resets.
