OPQRcoder vs OneTimeShare
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
OPQRcoder

Standard QR codes contain unused "padding" bytes after the encoded data. OPQR writes your image into those bytes — invisible to scanners, visible to eyes. Select an image or take a photo and generate code with any text.
OneTimeShare
Read full descriptionHide full description
You can select a photo stored on your iPhone and upload it to the cloud. A QR code will appear to download the image. The URL is valid for one day and the number of downloads is limited to one. The photos are encrypted using AES-GCM. The key is written in the fragment part of the URL and decrypted locally (E2E encryption). As long as the URL is valid, anyone who knows the link can download the photo. Please be careful when sharing. If you select this app as a destination with a single photo selected in “Share” with the Photos app, you can launch this app from the Photos app. If you select this app as a destination in “Share” with Safari or App Store, a QR code for the URL of a web page will be displayed in the Share Sheet (this is a feature unrelated to photos.) It will be similar to the QR code generation in Chrome's “Share” options.

Verdict
The clearest difference is in-app purchases: OneTimeShare at none against OPQRcoder's 1. OneTimeShare also leads on update cadence (daily vs every 16 months). OPQRcoder's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
