01
The gap
Users downloading apps advertised as free are immediately blocked by paywalls or charged without consent, preventing them from testing core features. This erodes trust and frustrates users who want to evaluate utility before committing. Current apps like Package Tracker - pkge Mobile and Scanner App - Scan PDF & Docs advertise free access but lock functionality behind unexpected payments.
