Developer to Optimize and Improve an Existing iOS App - job 1 of 2

Need an iOS app developed to slightly optimize and modify an existing iOS app, test, make minor final changes and release the app. The app is simple and has about 5 views; it is a kid's story app that shows images for stories. Currently, signing up for the free month promo charges the user and this needs to be rectified. Further, changes are needed for the way the app holds on to downloaded... stories; need to expose a way to release and expire a download from the device. Need the developer to do the modification, test the app with purchasing and do the final touches before releasing it. The developer is fully expected to be with us until the app is fully tested after the modification and successfully published to the appstore. Please read the requirements below and only apply if you agree: • Excellent experience (more than 2-3 years) in developing iPad/iPhone apps • Be able to show previously built apps • Improve the app as described in the description • Test the app with the other features in and do minor modifications if needed to get it working (although it is unlikely that it will need more modifications) • Document the code • Optimize Firebase fetching • Develop in Swift • Be able to support until the app goes live in the AppStore • Stick to good coding methods and PR the code for our developers to review before merging to the master branch of the repo • Strictly, bid at or below the given rate. • 5* review for a job well done
