What this package is

Field is for work that happens away from the office. Staff record what they did with no signal at all, the app holds it on the device, and it uploads by itself once a connection returns, with nothing for the user to remember to press again.

It adds a camera inside the app for evidence photos or barcode scanning, and push notifications that appear on the lock screen rather than sitting unread in an inbox. Screens go up to ten, with separate access levels controlling who sees what.

If you remember one thing about how this differs from Install: Install needs a connection to do anything, Field does the work first and sends it afterwards. For field operations, everything depends on that difference.

Nothing has arrived yet

Once the signal returns the app sends what was waiting, with nothing for the engineer to press again. That is the part a real user never has to think about.

This mirrors the screen of the delivered app. Everything here lives in this page and is connected to nothing. The real thing writes to a database on the device and uploads when the signal returns, recording the time and who sent it for every entry.

Everything you get

This list is the entire scope of the package. Nothing is hidden in a contract.

Camera capture and scanning inside the app
Push notifications to the user's phone
Up to 10 screens, with different access levels per user
User manual in English, written for staff who have never seen the app
60 days of support after handover

Not included in this package

iOS. I will be straight with you: I cannot build it right now because I do not own a Mac. That is a tool limit, not a skill one. If you need both platforms, hire someone separately for iOS.
The Google Play developer account fee, a one-time 25 US dollars, paid under your own company name so the app belongs to you and not to me.
Pressing submit on the Play Store for you. I prepare every file and document, but the submission should happen inside your own account. I will walk you through it while you do it.
Ads and getting people to install it. That is marketing, a different line of work from mine.
A registered company on my side. I am one developer working under my own name in Thailand, and the contract is with me personally, not with an agency.

What I need from you before starting

Every question needs an answer, because these are the settings your system is built from. None of them can be skipped. If one is not settled yet, put down what you know today and we adjust it when work starts.

Everything Install needs Required

The shape of the app still has to be known: who uses it, what they do, where the data lives, and what phones they carry.

Which actions must work with no signal Required

Not every screen needs to. Making all of them work offline adds cost without adding value, so I build it only where you say it matters.

If two people edit the same record offline, who wins Required

This is the hardest question in any offline system, and the one most people leave unanswered until something has already gone wrong. Agreeing it beforehand means the app can decide on its own.

What is the camera for Required

Taking a photo to keep and scanning a barcode for the system to read are different jobs and take very different amounts of work.

What should trigger a notification, and for whom Required

Notifications that arrive too often get switched off in the first week, and then the important ones go unseen as well.

How many access levels do you need Required

This decides who sees and changes what. Adding it later means rebuilding almost every screen, so it belongs in the first conversation.

How the work runs

Tell me who uses it and where

Staff or customers, inside one building or out on the road. Those two answers change how the whole thing gets built, so they come first.

You get the scope and one price in writing

Scope, price, and what I need from you, in one English document. The price moves on four things: how many screens, whether it has to run with no signal, how much work the camera does, and whether you need a web console. Nothing gets added on later.

You try the real app partway through

I send install files while the work is going, so you are holding the app on a phone long before the end date, not waiting to see it at handover.

Handover and store preparation

Source code, install file, English manual and technical doc, and the files for a Play Store submission. Then 60 days of support.

Questions about this package

How long can it stay offline, and how much can it hold?

The data sits in a database on the device, so the limit is free storage rather than time. In practice a full day of work for one person is under a megabyte excluding photos, and photos are compressed before they are stored. A week with no connection at all is comfortable.

If records do collide, how do I know nothing was lost?

Nothing is lost. Every upload is recorded with a timestamp and the name of who sent it. If the rule we agreed causes one to overwrite another, the overwritten version stays in the history and can be read back. It is built to overwrite, never to delete.

Do push notifications cost anything monthly?

No. They use Firebase Cloud Messaging from Google, which is free with no message limit. Any cost would be on your own server if it needs a larger plan, and I give you that figure before it happens.

Why an in-app camera rather than the phone's own?

The in-app camera opens straight into a framed shot with one button that does one thing, and the photo enters the system immediately with no file picking. Using the phone camera and attaching afterwards takes more steps, and leaves copies of your customers' paperwork in a staff member's personal photo library.

Can we buy Install now and upgrade to Field later?

Yes, and you pay the difference at that day's price rather than starting again. But honestly, if you already know you need offline, doing it in one go is cheaper. Designing the data structure for offline from the start is simpler than opening it up afterwards.
