Home Service Booking Android App with Provider Tracking and Slot Scheduling

Booking a plumber, electrician or cleaner in most Indian cities still runs on phone calls, forwarded contacts and uncertain arrival times. A customer describes the problem, waits for a callback, and often has no confirmed slot, no fixed visit charge and no way to know whether the provider is actually on the way. The Home Service Booking Android App replaces that informal chain with a single booking flow: the customer picks a trade, compares nearby providers with ratings and visit charges, reserves a specific time slot, and then follows the booking's status from confirmation to arrival. Providers, in turn, see only confirmed bookings with a fixed slot, instead of juggling calls and messages across the day. The result is a small, complete scheduling system that demonstrates the real problems of two-sided service marketplaces — availability conflicts, no-shows, trust and status communication — in a form a student can build, test and explain.

The Home Service Booking Android App moves a booking through four stages: discovery, slot reservation, status tracking and completion. A customer opens the app, chooses a trade such as plumbing or electrical work, and browses provider profiles showing ratings, completed-job counts and visit charges. Selecting a provider opens a slot calendar for the coming days; each slot can be booked only once, so a confirmed booking removes that slot from everyone else's view. Once booked, the customer follows a status timeline — confirmed, provider assigned, on the way, arrived, work started — updated by the provider's app and pushed to the customer as notifications. After the job, the customer rates the visit, and the completed booking stays in history for easy rebooking of the same provider. Every stage is visible to both sides, so neither the customer nor the provider is left guessing.

1. The customer signs in with Firebase Authentication and picks a trade, then browses provider profiles with ratings, completed-job counts and visit charges.
2. The customer selects a provider, a day and an hour slot; the app checks Cloud Firestore and only offers slots that are still free for that provider.
3. On confirmation, the booking is written to Firestore, the slot is marked taken for all other customers, and a confirmation notification is sent.
4. The provider accepts the booking in the provider view, which moves the status to Provider assigned and notifies the customer.
5. As the provider travels and arrives, each status change is saved and pushed to the customer, who follows the timeline without calling.
6. After the work is done the provider marks the job complete, the customer rates the visit, and the booking moves into history for rebooking.

The Home Service Booking Android App is built around four capabilities that carry the whole booking journey: finding the right provider, reserving a slot that cannot be double-booked, tracking the provider's status, and keeping a usable history of every job. Provider discovery filters by trade and shows ratings, completed-job counts and upfront visit charges before any booking is made. Slot scheduling shows a per-provider calendar in which taken slots are visibly blocked, so two customers can never hold the same hour. Live status tracking turns the wait into a visible timeline, from confirmation through arrival to work start, with notifications at each change. Booking history and ratings close the loop, letting customers rebook a trusted provider in seconds and giving new customers honest evidence about quality. Together these four capabilities cover every step from first search to a finished, rated job.

• [Provider Discovery by Trade] Customers filter providers by trade — plumbing, electrical, cleaning, appliance repair or painting — and compare ratings, completed-job counts and upfront visit charges before booking.
• [Slot Scheduling with Conflict Checks] A per-provider calendar shows bookable hours for the coming days; once a slot is booked it is marked taken and removed from every other customer's view, so no slot is ever double-booked.
• [Live Booking Status Tracking] Each booking carries a visible status timeline — Confirmed, Provider assigned, On the way, Arrived, Work started — updated by the provider and pushed to the customer as a notification at every change.
• [Booking History and One-Tap Rebooking] Completed and upcoming bookings stay in one list with provider, date and slot details, so a trusted provider can be rebooked for a new job without searching again.
• [Ratings and Reviews] After a completed job the customer rates the visit, and the rating feeds the provider's profile, giving future customers evidence grounded in completed work.
• [Provider Profiles with Upfront Visit Charges] Each provider profile shows trade, experience, completed jobs, rating and a visit charge before booking, so the customer knows the starting cost with no surprise.
• [Booking Reminders and Notifications] Firebase Cloud Messaging sends a confirmation on booking, a reminder before the slot, and an alert when the provider is on the way or has arrived.

Feature status: Implemented — all 7 features above. Optional customization — in-app payment, live GPS map tracking, provider-side earnings dashboard. Future scope — multi-city provider onboarding, service-package subscriptions, in-app chat between customer and provider.
