03The approach
i
Local processing
Everything happens on your device. PDFs, workouts, settings, history — they stay on your iPhone. The apps work in airplane mode because that's how they're designed.
ii
No accounts, no servers
No sign-up, no profile, no email collection. The only outbound network call is to RevenueCat to verify your one-time purchase — content and behavior never leave the device.
iii
Pay once
One-time unlocks priced for what they are. No trials that auto-renew, no monthly fees, no "premium tiers". Subscriptions die when the company does — purchases don't.
Software you buy, not software that bills you. Built carefully for a small number of jobs.
