Bypass the App Store. Follow the file.
Phone converters in the store want installs, ratings, and photo permission for a job a tab can do. This spoke is that tab: Safari on iPhone, Chrome on Android, then the same URL on a Windows PC if someone emailed you a .heic. Cross-device is the point — capture on iOS, receive on Android, finish on a laptop if the stack is huge. Keep the tab in the foreground. Cellular is fine for a few pages. A full textbook scan belongs on Wi-Fi and preferably a laptop because decode is on-device. IDs and medical-adjacent stills never need to leave the phone as a server upload. If you wanted the AirDrop-to-Windows story, use the iPhone spoke. If you wanted zero account friction, use the free spoke. This page is literally “I’m on a phone.”
