Simple Power Apps Canvas App using one SharePoint List

I need someone to help build a simple Power Apps Canvas App for a production works order tracking process.

The app is for a small engineering company and will be used on shared Android tablets and mobile phones.

This is for a **simple, but modern look first version** that I can expand later.

## What the app needs to do

Operators need to:

1. Select a workstation / production area.
2. Scan or type a works order number.
3. Add multiple works orders into a batch.
4. Review the batch.
5. Submit the batch.
6. Save the submitted records into one SharePoint List.
7. View recent submitted records.

## Data source

The app should use **one SharePoint List only** for the first version.

Example list name:

WOTracking

No Dataverse, SQL, Power Pages, model-driven app or premium connectors unless agreed first.

Suggested SharePoint columns

The single SharePoint List can contain:

* `Title` — works order number
* `TrackArea` — workstation / production area
* `TrackDateTime` — date and time submitted
* `TrackDate` — date only
* `TrackTime` — time only, text format such as `HH:mm`
* `TabletID` — tablet/device name if available
* `InputMethod` — typed / scanner / batch
* `BatchID` — ID to group one batch submission
* `SubmittedBy` — user who submitted
* `Comment` — optional notes

## Required screens

First version only needs:

* Home page
* Works Order Tracking
* Batch Review
* Submit Result
* Latest Updates

## Main screen

The Works Order Tracking screen should include:

* workstation selector;
* works order input box;
* Add to Batch button;
* batch list/gallery;
* remove item from batch;
* clear batch button;
* review/submit button.

The important part is that the operator can select the workstation once, then scan/type several works orders before submitting.

## Submit logic

When the batch is submitted:

* add one row per works order into the single SharePoint List;
* include the same `BatchID` on each row in that submission;
* include the selected workstation/area;
* include date/time submitted;
* show a success/failure result.

## App style

The app should be:

* simple;
* tablet-first;
* mobile-compatible;
* large-button;
* easy for factory operators;
* easy for an internal IT manager to maintain.

Basic responsive layout is enough. It does not need to be overdesigned.

## Deliverables

Please provide:

1. Working Power Apps Canvas App.
2. One SharePoint List connected.
3. Batch add/review/submit working.
4. Latest submitted records screen.

## Important

This is for a first working version only. I want something simple that I can expand later.

Future features may include current status, full history, error logging, Datafile ERP export, assembly instructions, stock locations, incident reporting and IT tickets, but they are not required now.

Please confirm:

* your experience with Power Apps Canvas Apps;
* your experience with SharePoint Lists;
* estimated cost;
* estimated timescale;
* whether you can keep this simple and use only one SharePoint List for the first version.
