Android Keyboard Word Analytics

@Arunmohan001

Hi, I can build your custom keyboard using Kotlin + InputMethodService + MVVM architecture. I’ll capture typed words locally, process emotion tagging (rule-based or ML Lite), and store via Room DB. Weekly summaries will be auto-generated and visualized using MPAndroidChart with polished UX. Focus on privacy (100% local), performance, and seamless keyboard experience. Modular design for future extensions (topics, NLP categories). Includes APK, source code, and full documentation. Ready to start.

Hi, I've built custom Android keyboards and emotion-analytics dashboards before, so your word-sentiment tracking project is right in my wheelhouse. I'll implement the keyboard as an `InputMethodService` in Kotlin using Jetpack Compose, MVVM, and Room to capture and persist every word locally, tagging each with an emotion label via a lightweight keyword-based classifier that's easily extensible to new categories like parts of speech or topics. For the weekly recap—which I understand is the hero feature—I'll use MPAndroidChart to render interactive pie and bar charts inside a polished dashboard Activity, with horizontal scrolling through past weeks so users can track their emotional patterns over time. The architecture will be fully modular, so plugging in future analysis categories won't require rewriting core logic. I can start immediately and will deliver a signed APK, clean commented source, README, and a user-guide mockup as specified.

Hi, I'm genuinely excited about this project. Building a keyboard with real value beyond typing, especially one that visualizes emotional patterns—that's creative and meaningful work. I've spent 5+ years building Android apps with complex features, and I understand the nuances of creating a custom keyboard that runs reliably in the background. I'm comfortable with Kotlin, Room database, and modern Jetpack patterns. The emotion analysis and weekly charting is exactly the kind of feature I love architecting. Here's what I'll deliver: Functional keyboard capturing words and emotion tags seamlessly Local Room database storing data with zero cloud sync Interactive weekly recap with emotion distribution charts using MPAndroidChart Clean MVVM architecture so you can plug in new categories later (parts of speech, topics, etc.) Comprehensive testing across Android versions Signed APK ready for testing Well-commented source code with clear structure README with setup steps, permissions, keyword addition guide User guide mockups showing the weekly emotion chart I'll focus special attention on the chart UX—it's the heart of this product, and I'll make sure it's intuitive and visually compelling. I understand scope matters, so if anything needs clarification before I start, let's discuss it upfront. Ready to build this. When can we start? Cheers, Maisam

custom android keyboards use InputMethodService under the hood and word tracking plugs right into the onText and onKey callbacks. i can log word frequency, session stats, and push it to a Room database then display it with MPAndroidChart. what kind of analytics are you after, typing patterns or something like word prediction data? can start today and have a prototype ready in 4 days.

Hi, I will build the custom Android keyboard that captures user input, analyzes emotions, and presents weekly summaries in an engaging visual format. My experience with Kotlin and Java, alongside a strong background in MVVM and Jetpack libraries, ensures a clean and maintainable architecture. I will implement local data storage using Room for efficient word tagging and emotion categorization, ensuring all data remains on the device. The integration of MPAndroidChart will allow for a visually appealing display of the weekly emotion recap, focusing on clarity and user experience. To further refine the project, could we clarify which emotions you’d like to include initially? Also, are there specific design preferences for the dashboard? I’m ready to start immediately and ensure your vision for this project is realized effectively. Thank you.

Hi there Do you already have the full app flow, screen designs, and backend requirements ready, or should the first phase include planning and technical setup? Do you want the first Android release to cover only the core user journey, or should push notifications, payments, tracking, and extra integrations be included from the start? I can build your Android app with clean structure, reliable performance, and a user friendly experience that works well across modern devices. I focus on stable implementation, clear project flow, and release ready delivery, so you get an app that is easy to test, easy to maintain, and ready for Google Play submission when the core features are complete. I would be happy to discuss the project further on chat. Best Oleksandr Data Visualization, Data Analysis, Mobile App Development and Android

@AtharvaITS01

I have gone through the requirement for the custom Android keyboard with weekly emotion visualization. We have worked on Android applications and data-driven dashboards, and this seems aligned with our experience. Here is how we are planning to approach this: Keyboard Development We will build a custom IME-based keyboard that captures input efficiently without affecting typing performance. Emotion Tagging Initially, we will implement a keyword-based tagging system (happy, sad, angry, etc.). This keeps everything local and lightweight, and we can later extend this to more advanced models if needed. Data Storage All words and tags will be stored locally using Room DB, ensuring no data leaves the device. Weekly Processing We will use WorkManager to generate weekly summaries and maintain historical data. Visualization (Key Focus) We will design an interactive chart (likely pie + trend view) using MPAndroidChart to clearly show emotional distribution and changes over time. I have tried to keep the solution modular so future categories can be added without major changes. Please let me know if you would like us to prioritize the chart UX first or proceed with the keyboard + data pipeline initially.
