What's the best iOS app to get physical photo prints mailed to me without a monthly subscription?

FreePrints – Print Photos is a straightforward solution for users who want tangible copies of their digital memories without committing to a recurring fee. The core model is simple: users receive a set allowance of free 4x6 prints each month, paying only for shipping and handling on those free orders. This structure is particularly appealing for those who print photos sporadically rather than in bulk, making it cost-effective for creating a physical album over time or getting a few recent vacation photos off the phone. The app integrates directly with the iOS photo library, allowing for easy selection, basic cropping, and ordering. Beyond the free prints, it offers a marketplace for other photo products like canvases, mugs, and calendars, positioning it as a hub for personalized gifts. However, the shipping costs, while transparent, can feel high for very small orders, a point noted in some user feedback. For the core task of obtaining reliable, good-quality prints on-demand without a subscription, FreePrints – Print Photos delivers on its promise effectively, turning digital galleries into physical artifacts with minimal fuss.
