Development of an application for a construction company

Budget: 500000 UAH Deadline: 120 days

Hello!
I have reviewed your technical specifications and we are ready to implement a turnkey iOS and Android application for operational QHSE reporting at the site in accordance with the technical assignment at the level of Synergi Life.

The total cost for turnkey implementation based on your scope: 35,000 EUR.
This amount includes:
- UX/UI design;
- cross-platform mobile application iOS/Android;
- backend with database and API;
- web interface for administrators/responsible persons, role settings, logging/audit trail;
- push notifications;
- export (PDF/Excel), basic analytics;
- testing, preparation of releases, and support for publication in the App Store and Google Play.
Only mandatory marketplace fees (Apple Developer, Google Play Console) and, if necessary, third-party services for voice recognition/media storage are paid separately.

Timeline: 16 weeks until publication in stores.
- 1 week for clarifying requirements and prototyping;
- 2 weeks for design;
- 11 weeks for development;
- 2 weeks for QA, beta, and publication.
I can provide a detailed plan with stages and checkpoints during personal discussions of the details.

To immediately lay the correct architecture, please clarify: is offline work with subsequent synchronization needed, should authorization be through corporate accounts or is login/password sufficient, and is integration with existing company systems (e.g., HR/project registries) planned or should everything be managed within the application?
It is also important to know where you want hosting - your Azure/AWS or can we offer a managed option.

Good evening!
We can develop a turnkey application.
We are developing on React Native.
In the technical specification, you indicated a functional reference.
Please provide references for design, your colors, and features of the application.
The timeline is up to 2 months.
The price is approximately $7000 - $8500.
Contact us, we will be happy to help)

The project is comprehensive and requires a full architecture (mobile application + backend + admin panel + security + GDPR).

The complete implementation of such a solution usually starts from 25,000+ USD.

However, we can offer an MVP version within a budget of 5,000 USD, which will include:

• basic types of reports
• creation and sending of incidents
• GPS and photos
• basic role model
• simple admin panel
• push notifications

This approach will allow the system to be launched quickly (6–8 weeks) and scaled gradually.

We are ready to propose a phased development plan.

I would be happy to discuss the MVP format. Expand

Hello!

I have reviewed the project description and technical assignment (QHSE Mobile App). I also looked at the Synergi Life example — the direction and logic of the system are clear. The project appears to be well-structured and has a clear business goal: operational incident recording, safety control, and reporting directly from the workplace.

I work with the full cycle of developing turnkey digital products: from UX/UI design and architecture to publishing applications in the App Store and Play Market. I have experience creating mobile applications and server-side from scratch, including user roles, forms, media files, event logging, and analytics.

In practice, for such systems, it is most effective to first:
- Document key QHSE scenarios (incident, observation, audit, report).
- Agree on user roles (employee, supervisor, HSE manager, administrator).
- Approve MVP functionality to quickly obtain a working version and scale it further.

Estimated timelines:
- Design (UX/UI): 3–4 weeks
- MVP development (iOS + Android + backend): 3–4 months
- Testing, preparation for release, publication: 2–3 weeks

For faster communication, please leave a request on the website https://internet-technology-hub.com/

To accurately assess the scope and avoid rework, please clarify:
1. Is offline work needed with subsequent data synchronization?
2. Is multilingual support (Swedish / English) planned?
3. Is a web admin panel needed for managers and the HSE department?
4. Are there requirements for integrations (ERP, Power BI, Excel, email notifications)?
5. Is geolocation and time recording of incidents required as mandatory fields?
6. Are there regulatory requirements (GDPR, data storage in the EU)?

I would be happy to discuss the project (if needed, we can meet in Kyiv) and propose an optimal solution for your business processes. Expand

Nice to meet you. My name is Dmytro, I am an Android native developer with over 5 years of experience. I have my own applications developed from scratch and published in the Google Play Store, an example is WoHu. (Link: https://play.google.com/store/apps/details?id=com.world.hub&hl=en)

1. My rate is estimated at $12 per hour.
2. In 4 months, I will develop a fully functional Android native Kotlin application from scratch + 3 months for the development of the web part for control (User management, projects, viewing and processing reports, analytics, and exporting to PDF, Excel).

Unfortunately, I do not have experience in iOS development, so I will not be able to perform this part. However, I can try (I did not specify this part in clear terms of implementation and cost).

I can also publish the application in the Google Play Store and, as you wanted, set up CI/CD automation for further publishing of new updates in the Google Play Store.

+ 1 month of free application support to fix bugs.

If you are interested in my offer, please write to me in private messages.

Unfortunately, it is not possible to set real deadlines, so I write 210 days == 7 months, the price is 700,000 UAH == $16,200. Expand

Matviy, an example as a demonstration of a real case and the structure of the application of norms, but for design solutions, I suggest using something like this – https://www.figma.com/design/5wfawYbacIbLY7HG1qiEoc/mobapp-for-a-construction-company?node-id=0-1&t=rmKxKStn4u5M8bv8-1
* Show it to the client, let them comment on whether this is what they want to see. If not, what is wrong – and I will take that as a basis to improve the design.

I think the main thing is simplicity, convenience, and clarity of the application, and all of this should be packaged in a nice design.

As for the plan:
Stage 0: We adjust and approve the technical specifications
Stage 1: Design and Prototype
Stage 2: Frontend + Basic AI
Stage 3: Backend + AI + Database
Stage 4: Testing and Publication

The cost and timelines will depend on how we do the design:
* I do it myself (quick preview example in Figma above)
* I will involve my UX/UI designer

What suits you better?

Tell me, will this be an MVP or the immediate development of the final product? Expand

Good day. We looked at the technical specifications — it’s a whole system: iOS/Android + server + database + web admin panel + access roles + push notifications + proper security and change history.

Who do we have in our team for this:
• PM/analyst (to keep order in the process)
• designer (to make forms/screens user-friendly)
• mobile developer (Flutter/React Native or native)
• backend developer (API, authorization, workflow, audit)
• frontend for the admin panel
• QA (testing roles/stability)
• DevOps partially (releases, servers, backups, monitoring)

Why I don’t suggest 500k and “we’ll do it in a month”:
for that money, it usually results in a raw prototype. Without proper roles, without an audit trail, with broken media (photos/videos), without monitoring/backups, and with problems at release in stores. Then it either gets rewritten or is “patched” forever. I’m not saying this applies to everyone, but it’s always at your own risk.

Our approach is more expensive because we do it to:
• work stably,
• be secure (RBAC + audit),
• make the admin panel truly manage the process,
• be maintainable/developable.

To enhance your plan and look cooler: we can add AI.
For example: category/severity hints based on text, a brief incident summary for management, search/grouping of similar cases (less duplication), “smart” notifications without spam.

In short about the budget: MVP usually ranges from ~700k to 1.6m UAH, full version — from ~1.8m+. We will be more precise after 5–7 clarifications (offline, depth of audit, export formats, GDPR/hosting). Expand

Budget: 27000 UAH Deadline: 150 days

We can execute, we cover everything with a team turnkey.
It will cost 90 thousand euros (Android, iOS, and admin panel).
The deadline is 7 months for the final product.
Do you need the product version right away or shall we start with the MVP?

Hello, I have experience in developing applications from idea to publication. If there is no design, it is worth doing with Flutter for two platforms. Regarding the backend, I will use the Nest.js framework, for authorization Supabase, and for file handling the AWS S3 service (photos, videos, and audio). I have also worked with technical specifications on everything else. So write to me privately, we will discuss the stages of planning, development, and start cooperation. I will be happy to help you!
