iOS paywall

Apply ios-senior-ui-polish and ios-microcopy. Sell the unlock, then the price.

Five elements (all required)

Clear reason — One sentence for this moment, not “Go Premium.”
Specific benefits — Named capabilities with numbers. Icons + one line each. Adjectives without numbers are noise.
Price shown clearly — Plans visible. Annual and monthly if you offer both. What happens after the trial.
Trust line with detail — Charge date, amount, cancel window. “Cancel anytime” is a guarantee, not a footnote in 11pt grey.
Respectful exit — Labeled skip (“Maybe later”). Not only a tiny X.

Type	When
Hard	The feature is gated; continue is impossible without pay or skip-out
Soft	Upgrade is optional; the free path still works
Contextual	Hits at the moment of need (export 4, extra project) — usually best
