Android App Projects in Bangalore

A Kotlin Android application built with Jetpack Compose allows users to log workouts, track body measurements, and monitor progress over time. The app uses Room database for local storage of workout history and exercise library. A custom workout planner generates weekly schedules based on user goals (weight loss, muscle gain, endurance). Progress charts built with MPAndroidChart display weight trends, workout frequency, and personal records. Firebase Authentication handles user accounts; Firestore syncs data across devices. The app includes 47 pre-loaded exercises with animated demonstration GIFs and voice-guided rep counting using the device microphone.

An Android app displays real-time BMTC bus locations on a Google Maps fragment using simulated GPS data from a Node.js backend that models bus movement along 10 Bengaluru routes. Users search for routes, view the nearest bus stop, and see estimated arrival times updated every 30 seconds via WebSocket. Offline mode caches route and stop data in Room database. Push notifications via Firebase Cloud Messaging alert users when their bus is 5 minutes away. The app is built with Kotlin, MVVM architecture, Hilt dependency injection, and Retrofit for API calls. A companion driver app allows simulated location updates.

An Android e-learning application delivers video lectures via ExoPlayer, multiple-choice quizzes with instant feedback, and a progress dashboard showing course completion percentage and quiz scores. Content is stored in Firebase Firestore; videos are hosted on Firebase Storage with adaptive bitrate streaming. The app supports offline video download for learning without internet connectivity. A gamification layer awards badges for course completion milestones and maintains a leaderboard. The app is built with Kotlin, Jetpack Compose, and MVVM architecture. A web-based admin panel built in React allows instructors to upload content and view student analytics.

A personal finance Android app allows users to log income and expenses by category, set monthly budgets, and receive push notifications when spending approaches the budget limit. Transactions are stored in Room database with full-text search. A statistics screen displays spending breakdowns as pie charts and bar charts using Vico charting library. Recurring transactions are scheduled with WorkManager. The app supports CSV export of transaction history and PDF report generation using iText. Firebase Crashlytics monitors app stability. The app is built with Kotlin, Jetpack Compose, MVVM, and Hilt, achieving a 4.6-star rating in a 20-user beta test.

A food delivery Android application allows users to browse restaurant menus, place orders, and track delivery in real time on a Google Maps fragment. The backend is a Node.js REST API with MongoDB storing restaurants, menus, and orders. Razorpay SDK handles in-app payment processing. Order status updates are pushed to the app via Firebase Cloud Messaging. The delivery partner's location is simulated with a background service updating Firestore every 10 seconds. The app implements MVVM architecture with Kotlin Coroutines and Flow for reactive data streams. A restaurant admin panel allows menu management and order acceptance.

A mental health Android app provides daily mood logging with emoji-based input, a journal for free-text reflection, and a library of 20 guided meditation audio sessions. Mood data is visualised as a 30-day calendar heatmap and a trend line chart. A streak tracker encourages daily check-ins with notification reminders. The app uses Room for local storage and Firebase Authentication for optional cloud sync. A crisis support screen provides helpline numbers and breathing exercise animations. The app is built with Kotlin, Jetpack Compose, and MVVM. A 30-day user study with 15 participants showed a statistically significant improvement in self-reported stress scores.

An Android AR navigation app uses Google ARCore to overlay directional arrows and building labels on the camera feed, guiding students to classrooms, labs, and facilities on a college campus. Indoor positioning is achieved using Wi-Fi fingerprinting with a pre-built signal map of the campus. Outdoor navigation uses GPS with Google Maps Directions API. The AR overlay is rendered using Sceneform. The app stores the campus map and POI data in Room database for offline use. A search feature allows students to find any room by name or number. The app was tested with 30 first-year students, reducing average navigation time to a new location by 58%.

A civic engagement Android app allows residents to report local infrastructure issues — potholes, broken streetlights, garbage overflow, water leaks — by photographing the problem and submitting a geotagged report. Reports are stored in Firebase Firestore with the user's location from GPS. A public map view built with Google Maps SDK displays all reported issues colour-coded by status (open, in-progress, resolved). A municipal authority admin panel (React web app) allows officials to update issue status and assign field teams. Push notifications inform the reporter when their issue status changes. The app was piloted in a residential layout with 50 users, generating 127 reports over 2 weeks.

A Kannada language learning Android app teaches vocabulary and phrases using a spaced repetition algorithm (SM-2) to schedule flashcard reviews at optimal intervals for long-term retention. Speech recognition using the Android SpeechRecognizer API evaluates pronunciation accuracy by comparing the user's spoken input to the target phrase. The app includes 500 vocabulary items across 20 topic categories with audio pronunciation by a native speaker. Progress is tracked with a daily review streak, mastery percentage per category, and a cumulative retention curve chart. The app is built with Kotlin, Jetpack Compose, and Room, with offline-first architecture for use without internet connectivity.
