I have created a few iPhone applications for iOS that are all very simple. However, I do not know how to code them for Android. Thus, I would want someone to create the apps for Android for me. The app concepts are already mapped out and I can provide all images. For this project I would want to work with one freelancer on my most popular app. If everything works out, I would want to talk about working together again to recreate all my apps for Android. Please contact me for further details, I would want to have a non-disclosure agreement before committing to payment.
