We have a simple Flutter based application that uses tracking of a web view to facilitate a login and usage of our web based app. Due to updates of the various mobile OS's and flutter it has become out of date. We are looking for someone to bring the app up to date with the current OS releases and to ensure that the app functions properly so we can update the versions in both App stores. Versions of the application can be seen below: https://apps.apple.com/us/app/pax-training/id1239273774 https://play.google.com/store/apps/details?id=com.paxtraining.prod

We have an existing app that is fully functional, but it is no longer downloadable from Google Play because it was written about 10 years ago and targets an older OS. Here is what we need a skilled developer with good English speaking and communication skills to do for us: 1. Download and install the old version of the app. We have put it up on UpToDown to facilitate that if you do not have an older tablet or phone you can use. 2. We will provide test credentials so you can see and use all of the features in the app. This will serve as a real-world, fully functional guide to what the new app needs to do. Of course you can make improvements to the UI, but it should look and function just like the old app so that users will not be confused by the new version that you write. 3. I will answer any technical questions you may have. We also have a java library that may be useful to you. 4. It’s critical that you test your code – I can’t spend days and weeks testing your code for you. It doesn’t have to be 100% bug-free right from the start, but I don’t do will with developers that don’t test and debug their code. Experience in the payments industry is a plus but it’s not a requirement. Please include details on which development environment you will use for this project. Here are links to the app on Google Play and UpToDown (same app in both places.) https://play.google.com/store/apps/details?id=com.SmartTransactionSystems.giftcard&pcampaignid=web_share https://gift-and-loyalty.en.uptodown.com/android

App Concept: TriView - Visualizing Perspectives Objective: TriView aims to create a visualization of how a person perceives themselves, how they are perceived by someone who loves them, and how they are viewed by a complete stranger. This visualization will be achieved through AI-generated images based on detailed descriptions provided by the three parties. Functional Requirements: 1. User Profiles and Authentication: • Secure login/logout functionality. • Ability to create and manage personal profile. 2. Input Collection Interface: • Self-Perspective: • Text input where the user describes themselves in detail. • Loved One’s Perspective: • Invite functionality for a loved one to describe the user within the app. • Stranger’s Perspective: • An option to upload a user’s photo that can be shown to randomly selected, anonymized app users (strangers) who provide a description based on the photo. 3. AI Image Generation: • Integration with an AI-driven image generator that converts text descriptions into visual portraits. • Each perspective (self, loved one, stranger) triggers a separate image generation process based on the provided descriptions. 4. Comparison and Gallery Display: • Display the three generated images side by side for direct comparison. • User option to save images to a personal gallery or share on social media. 5. Feedback and Modification: • Users can provide feedback on the accuracy of the images and modify descriptions to refine results. • Re-generation option for new images based on updated descriptions. Design Considerations: • User Interface (UI): • Clean, minimalistic design focusing on ease of use. • Emphasis on visual elements such as the image display and comparison features. • Intuitive navigation through the app’s main functions. • User Experience (UX): • Engaging and seamless flow from description input to image generation and display. • Emotional design elements to enhance the personal and intimate nature of the app. • Notifications to encourage interaction from invited loved ones and to inform when a stranger’s description is complete. • Privacy and Security: • Ensure robust data protection, especially concerning personal descriptions and photographs. • Implement privacy controls that allow users to manage who can view their images and descriptions. • Technical Specifications: • Use of a robust AI image generation API capable of interpreting detailed text descriptions into accurate visual representations. • Scalable backend architecture to handle varying loads from image processing and user interactions. Market Differentiation: • The unique value of seeing oneself through different emotional and objective lenses. • Potential for psychological insights and self-awareness improvement. Target Audience: • Individuals interested in personal development, psychology, and self-perception. • Users engaged in social media who enjoy sharing insightful content about themselves. This structured approach provides a comprehensive blueprint for the app’s development, focusing on functionality that supports emotional and psychological exploration through visual imagery.
