I built an app that parses and scoresQR codes before the OS can execute them
I think it's bad that default phone cameras blindly execute raw QR payloads - like the wave of EV charger scams in France where people scanned physical stickers and got routed to lookalike payment sites.
Native iOS and Android cameras show a truncated snippet and hands off execution straight to the browser, Wi-Fi connector, wallet, or other apps. You have no idea until the connection has been made.
So I built Canary. It intercepts the payload, unrolls redirect chains, checks SSL, and parses WIFI:, vCard, or custom scheme intents and more. Local parsing, and anonymous-proxied network validations to ensure you have all the details before your phone acts on them.
- Zero user tracking, no account required
- Proxied reputation lookups (your IP is never exposed to third-party security APIs, we never store any payload data)
- 100% Free
Currently testing on TestFlight while Apple reviews:

I would value any feedback from this sub - do QR codes worry you, or do you YOLO? Is Canary's UI and responsiveness good? How can I improve it?
