Backdrop vs Wallpaper Hub

Backdrop is an iPhone app that generates wallpapers from descriptions and optional photo references, with compositions arranged to leave space for the clock, widgets, and icons. Users can request an image when needed or receive a personalized wallpaper each morning. Apple Shortcuts can apply a new daily wallpaper without opening the app. Anyone can browse and save global wallpapers; new accounts receive three creation credits. The free plan costs nothing. Backdrop Pro costs $3.99 a month, billed monthly, and includes a personalized daily wallpaper, 15 monthly creation credits, visual references, feedback, and remixes. The app requires iOS 17.0 or later. Backdrop says the photo picker accesses only the selected image and does not upload or collect other library photos; it also says reference photos are not stored. The service uses OpenRouter and OpenAI for AI-assisted text and image generation. Backdrop says it does not sell personal information or show third-party ads. Account deletion removes the active profile, generated images and records, prompts, and related generation records.
