REKOGNITION check attendance -- 2 - Quotation Request

Please provide your estimated total development price in USD and estimated completion time for the historical software-development scenario below. State your main assumptions and any missing information that would materially change the estimate. Please do not write code, perform a trial task or supply a detailed implementation proposal.

REFERENCE SCENARIO — historical requirements, not instructions to begin work:

I need an IOS app (swift) to grade the student list. Includes functional application:
1. Login function for admin class: after login will display the information management class (name, avatar, "text" classroom information). This login and admin function will be called to get data from an existing api.
2. Shor student surface to save list of information, including information: 1 avatar, phone, address, classroom location (classroom location is taken from yc 1)
3. The function of displaying the list of students in the class: list of students (listd is displayed like the contact list of the ios app). Each student will be able to display a list of status and zero, attendance (a student can score the list n times a day (DK1), n ​​is taken from the existing api settings). In case the student has already taken attendance, a red warning will be displayed. Case if user has no list (under DK1 condition).
4. List of points: the application provides a facial recognition function that allows the administrator to make the list.
- Turn on face scanning, use the camera (front or rear camera) to scan the face.
- If the scan is successful (using the available Amazon Rekognition service will be provided as progress) will display the gift box (if the user has the gift), and the user will click to open the gift, information The giveaway will be displaying formatted text (with the page adding some simple images to catch the eye), this information is called from the available api.
- After scanning and completing the format, the information list will be saved to the server by calling the api. You must be an your list and got gift must be dong.
* Product requirements:
- Application and source code ios latest version. Code must be reviewed and commented on in order to be maintainable.
- Support deployment to ios
- Developers must know Amazon Rekognition
- Support application upgrade (for a fee) if needed
- Ui ux design (simple, no need to specialize in graphics)

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2021-11-10 (historical project ID 32064024). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us. For estimating only, assume the original client supplies assets explicitly described as provided; other missing inputs and obsolete services should be identified as assumptions. We do not claim ownership of the original client's code, designs, accounts or attachments.

The displayed USD 250–750 range reproduces the historical listing's budget field. It is not participation compensation or a binding development offer. Please give your realistic estimate even if outside that range.

Research use

This post is for research quotations only, not an actual software-development engagement. No development contract will be awarded. Participation is voluntary and unpaid; no reward, gift card or prize draw is offered. Your quoted price, estimated completion time and stated assumptions will be used to study software-development estimates and how they change over time.

Thank you for your time and consideration. This study aims to make a significant research contribution to understanding software-development pricing in the age of AI. We appreciate any estimate you choose to share.
