MVP built & small customer base - Now looking for a technical co-founder (North America)

Hi all,

I've developed a B2C ios app (Swift/Firebase) called Fitcrony https://www.fitcrony.com/ via a development house that allows trainers gyms and studios to create workouts for their members. The app has been well received especially with lockdowns around the world as trainers need to be able to provide a hybrid model.
I have 10 trainers using the app at the moment and would like to now offer an Android version.

Also, a little bit about me. I've Co-founded a company Fitness SAAS company before and my main strength is sales and growing the user base.

I'm looking for a technical co-founder based in North America that can help develop an android version, I'm thinking flutter or react native.

Looking forward to hearing from you
