I need a lightweight Android app that helps divers calculate “diving difficulty” on-the-go based on three parameters. The flow is straightforward: the user types a numeric value, then picks two additional parameters from dropdown menus. Once they confirm, the app should read a local JSON file, match the three inputs to the correct record, and immediately show the difficulty result on screen. I will supply the JSON dataset, so you only need to parse it efficiently and present the matching value with minimal lag. A clean, single-screen interface is enough; no elaborate navigation is required. I’m comfortable if you build in Kotlin or Java through Android Studio—whichever you’re fastest with—as long as the final APK runs smoothly on Android 8.0 and above. Monetisation is essential. Please integrate Google AdMob banner ads on the main screen and make sure the layout still feels uncluttered for users. Add an option to pay to remove ads. Key points to cover: • Three user inputs: one free-text number field + two dropdowns. • JSON parsing to fetch and display the matching “diving difficulty” value. • AdMob banners integrated and tested. • Clean, touch-friendly UI and well-commented source code so I can expand the data set later. I will provide the logo and website to use. Hand-over items: full Android Studio project, compiled APK for quick testing, and brief read-me explaining where to swap in updated JSON or ad unit IDs. If everything loads quickly, displays the correct result, and ads serve without blocking interaction, I’ll consider the work finished and leave a 5-star review. POST ONLY YOUR FINAL BID TO COMPLETE THE PROJECT. If you chat with me after and change your bid to ridiculously higher I will ignore your bid. Make sure to read the description and provide a bid that matches your work.

With over 5 years of experience as a Full Stack Web Developer and in-depth knowledge of mobile app development alongside my proficiency in Kotlin and Java, I am confident I can build the Simple Diving (FINA) Android application to your specification. My skills with HTML5, CSS3, JavaScript and various frameworks such as React.js, Node.js, [login to view URL] are well-suited for handling the JSON dataset, parsing it promptly to display the accurate 'diving difficulty' value. As for the design, I have a keen eye for creating clean and intuitive user interfaces that prioritize functionality without sacrificing aesthetics. Additionally, monetization is a crucial component to consider in this project, and I understand it thoroughly. I will ensure effective integration of Google AdMob banner ads while maintaining an uncluttered layout for user comfort. In line with monetizing strategy, I will also incorporate an option within the app for users to pay to remove ads which will further boost your app's revenue potential.

Hi, I understand you need a lightweight Android app that quickly calculates diving difficulty using three inputs and a local JSON dataset, with a clean single-screen UI and built-in monetization. Performance, accuracy, and simplicity are key. My approach would be to build the app in Kotlin using Android Studio for modern performance and maintainability. I will design a minimal interface with a numeric input and two dropdowns, then implement efficient JSON parsing with in-memory indexing to ensure instant lookups. The result will display immediately with no lag. I will integrate AdMob banner ads in a non-intrusive layout and include an in-app purchase option to remove ads. The code will be well-structured and commented so you can بسهولة update the JSON dataset or ad settings later. Before delivery, I will test across Android 8.0 and above, validate all input combinations against the dataset, ensure fast load times, and confirm ads display correctly without affecting usability. A complete project, APK, and clear README will be provided. Best, Justin
