App for builders

Budget: 2000 EUR Deadline: 35 days

Good afternoon, I am engaged in cross-platform mobile app development on Flutter for iOS/Android.
In addition to layout, I can implement the backend - the server part on Python Django, and the administrator will have a web admin panel for navigation and system management.
Available for work - ready to start immediately

Hello! My name is Oleg, I am a developer of cross-platform mobile applications (Flutter). Your technical specifications are clear and very applicable, especially for the construction industry. I am ready to implement an application with GPS tracking, time accounting, exception modes, notifications, and an admin panel.

🔧 What will be implemented:

Automatic recording of arrival/departure from the site (geofences)

Manual and GPS-based time tracking

Statuses: "temporary absence", "in work", "off-site"

Privacy: disabling tracking outside of work hours

Admin panel with timesheet, charts, GPS control

Android/iOS support, energy efficiency, authorization

📱 Technologies: Flutter + Firebase / Supabase (or another backend upon agreement).

🕒 Timeline: ~3–4 weeks
💸 Budget: from $2500 for full turnkey implementation

We can start with a prototype or MVP, gradually expanding functionality. Ready to promptly discuss technical details.

Best regards,
Oleg Expand

Good afternoon,

Our team at Consider It Done Technologies is interested in helping you create your project. We have extensive experience in developing mobile applications for Android and iOS platforms.

Typically, we use the following tech stack for such projects: React Native for mobile devices and Node.js for the server, and we recommend using them for your app development.

Our team is ready to provide UI/UX design, technical architecture, internal infrastructure, and cross-platform development. We can handle implementation, testing, and full release management — including QA and successful launch on the App Store and Google Play. We can deliver an MVP with core features in just a few weeks, and we are ready to start as soon as possible.

To estimate timelines and costs, we would be happy to discuss project details, including technical requirements and design, during an introductory call with our CEO and CTO. If you're interested, I would gladly continue our conversation in private messages and answer all your questions.

Best regards,
Gregory, CIDT Expand

Hello.
I have reviewed your technical assignment for the construction workers' time tracking application. The project is interesting and has a clear practical focus.
I will develop the application simultaneously for iOS and Android with native modules for GPS tracking and background operation. I have experience with geolocation and time tracking systems, understand the specifics of energy efficiency and stable background operation. I am ready to discuss architecture details and show my work.

Good afternoon! I can do it according to all the requirements. Ready to discuss

Budget: 4000 EUR Deadline: 40 days

Hello,
This system has a clear goal and structure, which is an excellent foundation. I would set it up with reliable GPS logic that handles edge cases such as short exits or background loss. I would create a robust offline data buffer so workers can continue logging even with poor signal. The admin panel will include full logs, route viewing, and override controls for each record.
I would use React Native for the mobile app and FastAPI with PostgreSQL for the backend. The backend will include a task scheduler for automatic tagging and summary generation.
Let's create a tool that truly saves time rather than wasting it.

Hello Alexander!

We have reviewed your technical assignment. Our team Coderfy has relevant experience in mobile application development, and we are ready to take on your project.
Technology stack: We develop with React Native (for iOS/Android) and Node.js (server). This is optimal for speed and budget.
Timeline: Full functionality according to the technical assignment will take about 4 months. To provide an accurate cost, we suggest discussing the details in a short call. We can also offer a quick MVP version with key features for launch.
When would be convenient for you to have a call?

Budget: 5000 EUR Deadline: 30 days

Hello!
We are a small full-cycle development team. We specialize in mobile app development, backend development, and creating admin panels for managing mobile applications.
We have experience implementing very similar functionality within a project. But in this case, the presence of a person at the location was determined both by geolocation and by scanning a QR code upon entry and exit.
We are interested in your project and are ready to implement it, including the backend and admin panel. Usually, we recommend developing applications with such functionality natively, but cross-platform is also possible.
We have a few questions:
1) Is there a design for the application?
2) Admin panel - am I correct in understanding that you mean a web admin panel?
3) How will the application be installed - published in app stores or via APK/TestFlight?
I suggest discussing all the details via correspondence.
I can specify the budget after discussing all the details. Therefore, for now, the rate is unfortunately a standard one.
