The problem OpdReady solves

It provides a secure way to store your medical information. The users don't have to carry their files again and again. Don't have to repeat the same details again and again. All they have to do is carry the phone and it's available immediately.

Challenges I ran into

The main challenge I ran into was storing the IPNS key. The key generated through the w3name package has a signing key which is of the type UINT8Array. It took a while to figure out a way to store and retrieve that key to generate the signing key to enable users to update the information. The updated information is stored as a new revision against the IPNS key.
