Mobile Application Developer in Ranchi

Why the developer needs your decisions first

A mobile application developer can only build what has been decided and written down. When user roles, screens or sample data arrive halfway through a project, screens get rebuilt and dates move. In business app projects, delays usually come from questions nobody on the client side had answered yet, not from the coding itself.

This page lists what MATROP’s developers in Ranchi will ask you for, why each item matters, and how we then test the app with your own staff before it goes live. You do not need technical knowledge for any of it. You need someone who knows how the work is done today.

The six things to bring

1. User roles and what each person can do

List every type of person who will log in, for example salesman, area supervisor, billing clerk and owner. For each one, write what they may see, add, edit and approve. A salesman might book an order and see his own customers’ dues, but not change prices. The supervisor might approve a discount. Roles decide the login, the menus and the reports, so they come first.

2. A screen list

Write one line per screen, in plain words: “Today’s visits”, “Shop details with last three orders”, “New order”, “Payment collected”, “My day summary”. You do not need designs. A photo of the paper form or register you use now helps a lot, because it shows which fields you fill and in what order.

3. Sample data

Give real examples: twenty products with their actual names and units, a few customer records, your rate card, an old invoice, a completed job card. Testing with “Product 1” and “Test customer” hides real problems, such as long product names that break a screen, an item sold in three units, or a customer with two phone numbers. If some data is sensitive, mask names or numbers; the structure is what matters.

4. Offline needs

Tell us where signal drops: rural routes beyond Ranchi towards Gumla or Lohardaga, a basement godown, a hospital ward. If staff must keep working there, the app has to save entries on the phone and send them when signal returns. The scope must also say what happens if two people change the same record while offline. This is a design decision, so it must be made before development, not added later.

5. Test devices

Name the phone models your staff actually use, including the oldest one still in service, and lend one or two for testing if you can. Low storage, older Android versions, small screens and battery-saver settings that stop apps in the background only show up on real phones. If iPhones are involved, say which models. If the platform itself is still undecided, see how to choose between Android, iOS or both.

6. One approver and a sign-off rule

Name one person who approves the screen list, the designs and each test build. When three managers send different changes on WhatsApp, nobody knows which one is final. Agree that each stage closes with a written OK, and that new ideas after sign-off go into a list for the next version.

Checklist: who provides what, and when

At the end of the project you should also receive certain items back from the developer. Our page on hiring an Android app developer has the handover checklist. For a wider guide to writing requirements, read how to scope a custom software project.

Example: an app for field service technicians

Here is a typical case, not a named client. A company services water purifiers and inverters at homes across Ranchi and nearby towns. Fifteen technicians take jobs by phone call, and the office does not know which jobs are finished until evening. This is how the six inputs look for them:

• Roles: technician, supervisor, office coordinator and owner. Technicians see only their own jobs. The coordinator assigns jobs. The owner sees all reports.
• Screens: today’s jobs, job details with address and map, start job, parts used, photo of the installed unit, payment collected, and job closed with a customer OTP.
• Sample data: the parts list with prices, twenty real past complaints, and the current job card.
• Offline: many jobs are inside buildings with poor signal, so a closed job is saved on the phone and synced later.
• Devices: the budget Android phones the technicians already carry.
• Approver: the operations manager signs off each stage.

Field roles like this appear in our real work too. In the Kabadi case study, pickup partners have their own view in the role-based platform MATROP built, covering assigned orders, status updates, weight capture and proof of collection, while warehouse, plant and admin teams each work in separate logins.

How testing with your real staff works

1. Our own testing first. We test each function on several phones, including slow ones, and fix the obvious problems before you see a build.
2. A small group of your staff. We install the test build on two to four staff phones: one experienced person, one new person, and whoever has the oldest phone. They do real tasks with your sample data.
3. Watch, do not explain. Someone from your side and ours watches a staff member use the app without help. Where they hesitate is where a screen needs to change.
4. One real day side by side. Staff record actual work in the app and in the old method for a day or more, and the totals are compared in the evening.
5. One shared issue list. Every problem goes into one list with the phone model and a screenshot. We fix it and send a new build.
6. Sign-off, release and training. The approver signs off, the app goes to all users, staff are trained, and the first week of real use is watched for problems.

When you are not ready to hire a developer yet

If you cannot yet name the roles, or your process changes every week, spend two weeks writing down how the work actually happens. We can help you list it at the first meeting. If nobody can give an hour or two a week to answer questions and test builds, the project will stall, so wait until someone can. And if you want a developer on your own payroll, that is a different arrangement: work with MATROP is a company project with a written scope, a company invoice and support from the team.
