SealProof runs a timed pressure or leak hold and turns it into an automatic pass or fail you can hand over. Start the hold from your Apple Watch or iPhone. Interval haptics keep time while you watch the elapsed against the required hold, then log the end reading on your wrist. SealProof compares the start and end readings against your tolerance, flags the pressure-drop rate against a code threshold, and produces a pass or fail certificate you can share on the spot. What it does: - Run a timed pressure or leak hold from the wrist with interval haptics and a big go/stop - Enter start and end readings for an automatic pass or fail against your tolerance - Pressure-drop rate flagged against a code threshold - Code-set presets for common durations and pressures (plumbing, gas, HVAC) - Per-asset test history you can trust, with pass rate and trend - Pass or fail certificate PDF handed over on the spot - Temperature note and optional correction so cooling is not read as a leak - Syncs across iPhone, iPad, and Apple Watch with your private iCloud Free: run and log timed tests for one asset. Pro (one-time unlock): unlimited assets, the code-set presets, certificate export, full history, and private iCloud sync. One payment, yours forever, no subscription. Your record stays private to you, on your devices and in your personal iCloud. No accounts, no analytics, no tracking. SealProof records the readings you enter. A certificate is a field record, not an inspection sign-off or a guarantee of code compliance.

Verdict
The clearest difference is in-app purchases: Nastec NOW at none against SealProof's 1. SealProof's advantage is update cadence (every 2 weeks vs every 4 weeks). On price, ads, device support and iOS requirement there is nothing between them.
