Development of an application for a gym network

Budget: 12000 UAH Deadline: 7 days

I have been developing applications for about 2 years. I am ready to quickly and affordably create an MVP for you, and then expand the functionality further.

Budget: 10000 UAH Deadline: 10 days

Hello! The task is very clear. Since at this stage only data output is needed without complex transactions and sending, this is an ideal option for quickly creating a cross-platform MVP. I develop software and have extensive experience with relational databases such as SQLite, SQL Server, and Supabase. For your task, I will create a single application that will work reliably on both iOS and Android. We can connect it to your existing database or deploy a new one via REST API, so the application simply fetches information and displays it in a user-friendly interface. I would be happy to discuss the details and start collaborating!

Good day!

I am interested in your project. We propose to implement a mobile application on Flutter for iOS and Android — this will allow for a single codebase, simplify further development of functionality, and support for the application.

We have significant experience in developing mobile applications of varying complexity — from corporate systems and CRMs to services with integration with external APIs and large volumes of data.

Before providing an accurate estimate of cost and timelines, I would like to clarify a few points:

- Is there an existing backend and API, or do they also need to be developed?
- What specific screens should be included in the first version of the application?
- Are search, filtering, sorting, or pagination of data expected?
- Is there a ready design (Figma or other mockups), or does it also need to be developed?
- Is offline functionality or caching of information on the device required?
- Do you have a more detailed technical specification for work on Stage 1?

After receiving the answers, we will be able to prepare a detailed estimate and propose the optimal implementation option.

We will gladly send examples of mobile applications we have developed in personal messages. Expand

A cross-platform application is needed for a network of gyms that pulls data from a database and displays it to the user without any submission forms.

I will create it using React Native: one codebase for iOS and Android, which simplifies maintenance. I will connect to your API or database via REST/GraphQL, set up navigation, and display data (schedules, trainers, gyms). The architecture will be designed so that it is easy to add bookings, payments, or push notifications later without rewriting.

The cost and timeline depend on the number of screens and whether there is already a backend or if it needs to be designed as well.

What is the current data structure: a ready API, a database on the server, or still at the idea stage?

Budget: 25000 UAH Deadline: 30 days

Good day! I am interested in your project. I specialize in developing mobile applications for iOS and Android.

In order to accurately assess the cost and timeline for development, I would like to clarify a few details:
1. What specific database is being used (Firebase Firestore, MySQL, PostgreSQL, or another)?
2. Is there an existing API for data retrieval, or does it also need to be developed?
3. What language should the Android application be implemented in: Kotlin, others?
4. Is the development for iOS expected to be done in Swift?
5. Is there a design (Figma) and technical specification, or do they also need to be developed?

After clarifying these details, I will be able to provide an exact cost and timeline for completion.

I look forward to collaborating! Expand

Hello, I have experience in application development from idea to publication. For output, the information is a small amount and time. I can provide a full development cycle + design (depending on your needs). Feel free to message me for examples. I would be happy to help you!

Budget: 27000 UAH Deadline: 21 days

Good day!

I am interested in your project. I am a mobile developer with 10 years of experience in creating applications for iOS. I propose to implement this project using React Native.

From the description, it is currently difficult to assess the exact scope of work, so I initially estimate 3-5 weeks, after reviewing the technical specifications or the list of screens.

Most of my commercial projects are under NDA, so I cannot send source code or internal materials. However, I can discuss my role in the projects, the technical solutions used, and, if possible, provide links to applications that are published in the App Store.

I would be happy to discuss the details and propose an optimal solution.

Hello, Anna!
Our team has experience in developing cross-platform mobile applications for the sports and fitness niche, including a SaaS application for fitness studios, as well as many applications for clubs with racquet sports. Therefore, creating an application for your network is not a problem. Please write in more detail what data should be displayed, what information to output, and whether you have a website. Let's discuss the details, and I will guide you on pricing and deadlines.

One ball solves everything — that is, where the application gets its data. If you already have a server with a database, I will connect directly to it; if the database is not yet online, I will set up a separate backend with an admin panel where you can manage the schedule, coaches, and subscriptions without releasing the application.

Expo: one code for iPhone and Android, list and card screens, search, offline cache — the schedule is visible even without the internet. I will handle the setup for your accounts in the stores myself. You will open a screen with your real data on your phone through Expo Go on the fourth day, even before the rest is ready.

From mobile: an email client on Expo with a Python backend, brought to TestFlight — meaning the builds and certificates have already been completed. I currently have no reviews on the marketplace, so payment goes through Safe: you reserve the money and release it after acceptance. Recording data can then be added on top of the same database, without rewriting.

22,000 UAH, 12 days of my work, edits according to your comments up to 15. App Store review — separately, this is Apple’s calendar. Just tell me one thing: is the database on your own server or in a club accounting program like 1C? I will read the response — and return a list of screens with deadlines for each.

I already have a practically ready similar solution that can be quickly adapted and launched... I suggest we discuss it now, I am available ))

The preliminary cost of the application for iOS and Android is 140,000 UAH, the term is 35 days.

Is there already a ready API for retrieving data from the database?

How many screens are approximately needed, and is user authorization required?

Good day!

I am ready to take on the development of your application for iOS and Android. I can start working immediately after agreeing on the details.

I have experience in developing mobile applications using React Native / Expo (CRM, business applications, social services, client applications), as well as over 3 years of Full Stack development experience (React, Next.js, NestJS, Express). Therefore, I can not only implement the mobile application but also develop its functionality and server side in the future.

At the first stage, I can implement:
• authorization (if needed);
• connection to your database/API;
• quick and convenient information viewing;
• modern responsive interface for iOS and Android.

After clarifying the details (data source, number of screens, logic of operation), I will be able to provide an exact cost and timeline.

Anno, to implement the application for retrieving information from your database, it is necessary to ensure a stable connection to the API and correct display of structured data on iOS and Android screens. I will design an interface that will be easy to scale for future features when you want to add interaction capabilities with the application.

Instead of complex solutions, I will focus on a clean architecture that will allow you to quickly access information without delays. What is the volume of data and in what format is it currently stored in your database so that I can assess the structure of the API requests?
