Yeah Nostore works for web apps using Safari. I think if you want to use another native iOS client (e.g. the Primal or YakiHonne app) then you still need to use your private key directly.
You guys are legends appreciate all the help with this 🙏🏽🍻
Check out Orion browser. It lets you install Firefox and Chrome extensions 🤩 https://kagi.com/orion/
100% testify that orion is awesome so far! It's the only iOS browser that lets you install both FF and Chrome extensions! giving you access to every single nostr enabled website through: Nos2x for chrome Nos2x-fox for firefox (Can use either on Orion tho!) Once you've thrown your nsec into the nos2x extension, check out https://nostrapps.com and be blown away. I personally use Nostrudel but there are dozens! Pick your flavour 😝
