I need help establishing a dependable, real-time method to follow one person’s physical whereabouts strictly for personal safety. The goal is to know where they are at any moment so I can react quickly if an emergency arises. Your job is to guide me through choosing suitable hardware (phone-based, vehicle-mounted, or any discreet standalone GPS you feel works best), set it up, and integrate it with a dashboard or mobile app that shows live location, movement history, and optional geofencing alerts. Because this is physical tracking, accuracy, battery life, and covert placement matter. Deliverables • Device and software recommendation with links to purchase or download • Step-by-step setup, pairing, and calibration instructions • Configuration of live map, histo...

I’m building a first-run prototype of a smart band that my dog can comfortably wear. The core requirements are clear: • Location and activity tracking in real time • Continuous capture of GPS coordinates, movement patterns and basic behavioural stats • Seamless upload of that data to a mobile app for live map view and activity summaries Here’s what I need from you: 1. Hardware & Firmware Design a compact, pet-safe enclosure with a low-power MCU (ESP32, nRF52 or similar), GPS module and motion sensor. Write the embedded code that logs position once per set interval, streams accelerometer data, and packages behavioural metrics for Bluetooth transmission. 2. Companion Mobile App A simple Android/iOS app (Flutter or React Native is fine) that pa...

I need a complete mobile app (Android and/or iOS) that lets household users book a doorstep pickup for their recyclable dry waste and earn either cash or in-app points once the material is weighed and verified. Core flow • User signs up, selects the material type—paper, plastic, metal, or e-waste—and books a time slot. • A collector receives the request, arrives, weighs the items, and updates the weight through the app. • The system instantly shows the cash value or points credited to the user’s wallet. Key features I must see • Real-time scheduling with reschedule/cancel options. • GPS or map integration to route collectors efficiently. • Material-wise pricing table that I can adjust from an admin panel. • Digital weig...

We have various size orders of hardwood flooring that needs to be collected from our shop in Hudson, NH and delivered on average less than 30 miles away. We have trucks, if you provide vehicle we can discuss. Flatbed would be easier; we have three vehicles NON CDL. Loading will already be taken care of at the pickup point; what we need is safe transport and to hand unload bundles (35-50lbs) into the jobsite, existing home or business. Sometimes forklifts unload on receiver's end. Occasionally, we have multi floor delivery, we try to keep it 1st and 2nd floor or pay extra. Schedule varies. Looking for a local service to use regularly, but as needed. We will schedule with advanced notice. Our hours 7 AM and 4 PM M-F, no weekends. Nashua, Manchester, Northern MA, Seacoast and Lakes...

I’m building a city-focused marketplace that matches Saharanpur residents with trusted electricians, plumbers, mechanics, AC technicians and carpenters. The scope is strictly Android for this first release, and every user—customers and providers alike—will sign in with OTP only. What I need built: • Customer app – browse services by location, book a job, track status, pay through UPI or hand cash on completion, then rate and review. • Service-provider app – accept or reject jobs, live-track routes, manage profiles, view earnings and history, receive push alerts. • Web-based admin panel – full CRUD over users, categories and bookings, dispute resolution, payout reports, notification broadcast. Core modules include secure OTP authen...

I need a slick mobile app that lets people browse nearby “rental boyfriends,” see who is free, and lock in a timeslot instantly. The build is strictly mobile first, so everything—from onboarding to confirmation—has to feel natural on iOS and Android. Core focus The heart of the product is a real-time booking and scheduling flow. A user chooses a companion, checks live availability on a calendar, and confirms the appointment in just a few taps. Location-based matchmaking GPS data should automatically surface profiles closest to the user, with simple distance filters and a map view. Accuracy and speed are vital here; I don’t want lag between a user’s location change and the results they see. Key deliverables • Cross-platform mobile app (nativ...

• Pixhawk 2.4.8 clone running ArduRover 4.7.0 • DFRobot RTK LoRa kit (Quectel LC29H, NMEA output over UART) — base and rover, LoRa link confirmed working, rover shows solid RTK lock • Connected to the Pixhawk’s GPS port Problem: Mission Planner shows “EKF3 waiting for GPS config data” and never acquires a position. Already tried: • GPS_TYPE = 5 (NMEA), SERIAL3_PROTOCOL = 5 • GPS_AUTO_CONFIG = 0 • Every supported baud rate on SERIAL3_BAUD, rebooting each time • Swapping TX/RX (original orientation confirmed correct — receiver lost lock when reversed) • Confirmed the module’s I2C/UART switch is set to UART Looking for someone with hands-on ArduPilot experience to diagnose over a screen-share session. I can ...

I need a small Android-only solution that keeps a field employee’s GPS location streaming in real time for a full 10-hour shift. The phone should start tracking with a single tap, run quietly in the background, and push live latitude-longitude data to an endpoint I can inspect as it happens—no cell-tower or Wi-Fi fallbacks, pure GPS. Please build a lightweight app or service that: • Requests the necessary foreground/background location permissions once and keeps them alive. • Publishes location updates continuously (no noticeable gaps) for up to 10 hours without killing the battery or losing accuracy. • Lets me specify the update frequency before deployment—default can be every 5–10 seconds. • Saves a local log as a safeguard if the conne...
