---

We are urgently seeking a mobile app developer with expert-level skills in payment gateway integration and access & permissions implementation completion for our app's in-app purchase, Apple Pay, Google Pay, payment processors' integration for our newly completed mobile App. The successful candidate will play a crucial role in integrating secure and seamless payment options into our app, ensuring a smooth user experience. This is an exciting opportunity to work on a high-profile project with a talented team. The best developer for this minor project MUST be well-experienced in implementing in-app purchase payment gateways for iOS users and Google Pay for Android users. PLEASE NOTE THAT THIS WORK HAS BEEN DONE HALFWAY. So, you'll just be completing it. Responsibilities: - Integrate and configure the following payment gateways: For iOS OS: In-App purchase & Apple Pay first, and submit for approval. Then, Stripe payment processor after App is approved/published. For Android OS: In-App purchase & Google Pay first, and submit for approval. Then, Stripe payment processor after App is approved/published. Implement and ensure smooth and secure payment processing functionality! - Implement all the subscription plans on 2 different screens: 1. When a User is signing up/creating a new account for the first time, a.k.a. the screen before the App's main folders' screen (where the App contents are). 2. User's account profile screen under the "Subscription Plans". This will be the exact spot where the mascot is currently used as a placeholder for the subscription plan. NOTE: Implement all the subscription plans so that FREE users will see all the premium plans on display and subscribe to whichever one suits them, whenever they're ready to upgrade to premium premium membership. But Premium Users will see on their account profile page, only the plans they subscribed to and other higher plans, if they're currently subscribed to the lowest Tier premium plan. Also, free users should see all the premium plans each time they're signing in and a reminder should pop up to remind them to upgrade from time to time. - Complete the remaining tasks for all "access & permissions" implementations based on the subscription plans. Free users should be granted access to open all folders and subfolders (for the folders with subfolders) but they should be DENIED access to the actual files themselves. This means that FREE users can see the titles of all the files in the app but they cannot access/open/use the premium files. (until they eventually pay for premium membership). When a FREE user clicks on a premium file, the following message should pop up on their screen: "Please, upgrade to Premium Membership to access this file." - Conduct thorough testing and debugging of the entire App and ensure that all unnecessary assets are cleaned up, and anything else that may cause slow processing of the app must be fixed so that app's tabs open faster within 1 second of a click. Payment system reliability and App smooth functionality must be tested by a QA Tester before submission. - Daily Bible verses should be set to go off as Push Notifications at 6AM daily, and should say, "The Bible Verse of the Day", and under it, "January 1" then the applicable Bible verse from the Bible Verse spreadsheet should follow under the title. While the Daily Positive Vibes Message should be set to go off 6PM daily, with the title "Positive Vibe of the Day" and under it "January 1", then followed by the particular message of the day as seen in the Excel sheets for that. All time zones across the world. - The App's latest build MUST be tested on the following devices: All iPhones, iPad, Apple Watch, Samsung Galaxy phones newer models, Google Pixels phones, Samsung Tablets, etc., to ensure that the App meets all requirements! - The App's newest Icon and Feature Graphics MUST be uploaded and used before submission of the latest build for approval. - Integrate a "Search" bar to enable users to easily search for any type of content they're looking for, and all related files across the app, should populate for the user to choose from. - Implement the banners for the FREE eBooks for Premium Subscribers on the users' account info screen, using the eBooks' cover page that'll be provided to you. Details are in the requirement document. - Implement the congratulations feature with multi-colored flower pieces to burst out whenever a user completes listening to or reading a file, with messages like: "Big Hearty Congratulations for Completing Your Meditation!", "Huge Congrats for Completing Your Hypnosis!""Huge Congrats for Completing Your Manifestation Affirmations!", "Big Congrats for Completing Your Gratitude Affirmations!" "Big Hearty Congrats for Completing Your Breathwork Exercise!", and "Big Congrats for Completing Your Sound Therapy!" - Fix the icons/buttons, and images that are not responsive so they can be responsive. - All images in the app are currently stretched. You’ll fix them to be normal. - Remove the Firebase link that is showing in the title on the Morning Gratitude Affirmation page. - iOS: Purchasing for one category unlocks every category. You’ll fix this in the payment gateway implementation. - Android: In-App purchase not working with an error message appears as “The item you were attempting to purchase could not be found”. Although This issue might be resolved after the app published successfully on Google Play Store, but it is your responsibility to fix it. - Create the IPA and AAB file packages for Apple and Google submissions and submit those to them for approval. - Respond to all feedbacks from Apple & Google until the App is approved by both Apple and Google.
