Development of an application for iOS
Hello, we want to create an application based on the principle of Saldo, focusing on financial literacy with integration of banks and eventually cryptocurrency, organizing expenses and spending.
We are interested in timelines and cost estimates for development, and would like to start with a skeleton and gradually fill in the application.
The design of the application is already available.

Good afternoon! A financial application for tracking expenses and integrating banking APIs is exactly our area, especially since the design is already ready. The approach of "first the skeleton, then gradually adding functionality" resonates with me: it makes it easier to lay the architecture for future crypto integration. Let's discuss the details and the budget in private messages.

Hello, I worked on Wallet Manager with tag:7748 - an application for financial management with integration of 15+ banks in Ukraine, processing over 50,000 transactions monthly.
I am curious which banks you plan to integrate first and if you are considering the possibility of adding expense categorization with AI?
I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team!

Hello! I will develop an iOS application for your task: I will agree on the functionality and screens, create a clean native UI, connect the necessary APIs/backend, and prepare the build for publication in the App Store. I work in stages with demonstrations of intermediate versions. I am ready to discuss the details of the technical specifications and the estimated scope.

The minimum viable version of the financial application with basic analytics and integration of one bank will require 400–500 hours of development. The determining factor for cost is the requirements for processing personal data and encrypting transactions, which are often overlooked at the sketch version stage.
The key challenge in phased implementation is maintaining the stability of the application's core while subsequently adding features. Potential risks include duplication of logic for working with APIs and loss of control over the architecture after several iterations.
I suggest starting with an MVP that includes connections to 2-3 banks, a basic expense report, and a limit alert system. At this stage, it is possible to test the correctness of processing crypto transactions without fully implementing the crypto platform.
What minimum functionality is important for launching the first metric of user engagement?

I have worked on similar financial applications with bank aggregation, so I understand what you mean. Essentially, this is a backend with authorization, transaction storage, data normalization from different sources, and expense categorization logic, plus an iOS front end with dashboards and budget management flows. For the skeleton, we can realistically start with manual expense entry and one or two banks through open banking or their official APIs, and connect crypto as a separate module later. Please let me know which banks you want to connect first, whether they have open APIs, or if you are considering aggregators like Plaid? I am ready to discuss the scope of the first phase and estimate the timelines.

iOS application in the spirit of Saldo: expense tracking and financial literacy, with integration of banks and crypto for the future, starting "from the skeleton" and gradually filling it in — this format is just right for me.
My experience is closest: I developed a native iOS app with a real payment stack (card tokenization, 3-D Secure) and a banking ledger — multi-actor balances, each operation as a typed transaction — on a platform with a million turnover. I have also touched crypto in production (crypto payments in a bot, exchange monitoring), so financial logic and crypto are not new to me.
The design is already available — this speeds up and reduces costs. I propose to start with the skeleton (your design + core expense tracking, iPhone/iPad, initially without backend) — approximately 3–4 weeks, ~$1500–2800; this is a range, the exact estimate will be after agreeing on the technical specifications with the design. Then we will fill in features: banks → analytics/literacy → crypto.
The main question regarding the range: integration of banks — through an aggregator (Salt Edge / Plaid) or direct bank APIs? This greatly affects both the timeline and the budget.
I am ready to outline a phased plan and discuss details in correspondence.

Good day!
I am interested in your project. I have experience in developing AI/fintech solutions, API integrations, user dashboards, automating financial processes, and backend architecture for scalable products.
Based on your description, I would suggest proceeding in stages to avoid spending a large budget upfront and to launch a working MVP more quickly.
The first stage is the "skeleton" of the application:
registration/authentication, user profile, basic application structure, expense categories, manual addition of income/expenses, analytics, transaction history, integration of ready-made design, backend, and database.
… The second stage:
integration with banks, automatic transaction uploads, smart categorization of expenses, budgets, goals, notifications, reports.
The third stage:
crypto module, integration of exchanges/wallets via API, asset accounting, portfolio, transaction history, and advanced analytics.
Regarding the budget, I can provide a more accurate range after reviewing the design and the list of screens, but overall I would suggest starting with the MVP to quickly obtain a working version, test the idea, and gradually add functionality. We can also orient ourselves on the timelines.
I can join the project as a developer and assist not only with the mobile part but also with the backend, API, database, architecture, and further scaling of the product, as well as integrate a chatbot or another AI solution.

Good day! Very interesting idea.
Since you already have the design ready, we can build a solid technical foundation and gradually fill the product with functionality, so that we can easily scale the application in the future.
I would suggest starting with an analysis of the design, thinking through the architecture, and assembling the first working version with the possibility of further development.
Regarding technologies, we can consider several approaches:
- Flutter for cross-platform development for iOS/Android;
- native development for iOS and Android (Swift / SwiftUI and Kotlin) for maximum performance and deep integrations;
… - preparing a solution with future banking integrations and functionality expansion in mind.
I am ready to look at your mockups, discuss all the details in private messages, and propose an optimal implementation plan in stages.
I would be happy to collaborate 😊

Good day.
Your project looks like a product that should be launched in stages. If you immediately incorporate integrations with banks, expense analytics, transaction categorization, financial goals, and future support for cryptocurrencies, it is very important to first build the right architecture so that you won’t have to rewrite the system in a few months.
I am the CEO of Mobiwolf. We specialize in developing mobile applications for iOS and Android and can assist not only with implementation but also with planning the MVP, so you can get a working product faster and start gathering feedback from users.
In the first stage, I would recommend focusing on the "skeleton" of the system:
* registration and authorization;
… * user profile;
* integration with banks;
* categorization of income and expenses;
* basic analytics;
* budgeting and financial goals.
After that, you can gradually add:
* an AI assistant for financial recommendations;
* cryptocurrency wallets and crypto analytics;
* family accounts;
* advanced reporting and personalization.
For a more accurate estimate, I would like to clarify a few points:
* for which countries is bank integration planned?
* is synchronization needed via Open Banking API or do you anticipate manual entry of transactions at the start?
* is the design fully ready or just the main screens?
* is a web admin panel needed for managing users and content?
From experience, costs and timelines can vary significantly depending on the scope of integrations and the functionality of the MVP, so after reviewing the design and details, we can propose a more realistic roadmap and budget range.
I honestly note that we can start active development in about 3 weeks, but we are already ready to discuss the architecture, evaluate the mockups, and help determine the optimal composition of the first version of the product.
I suggest moving to a private chat — let’s look at the design and prepare a preliminary estimate for the implementation stages.
Best regards,
Oleksiy
CEO, Mobiwolf

We already have a nearly ready base for a similar fintech application - it can be quickly adapted to your design and launch the first working skeleton =)
Regarding timelines and budget - I would estimate the iOS skeleton with architecture, personal account, expense tracking, categories, basic analytics, and preparation for banking integrations to take about 35-45 days and cost between 180,000 and 300,000 UAH.
The complete first version with real banking connections, security, onboarding, subscriptions, or a crypto module will likely start from 450,000 UAH and above, because here the screens are not as important as data accuracy, protection, stable logic, and a solid base for growth.
> I suggest going step by step
>> first, the framework of the application according to your design, roles, navigation, expense tracking, categories, goals, reports
>> then connecting banks through available APIs or an aggregator, if it fits the countries and banks
… >> then smart tips on financial literacy, and we can add an AI assistant for analyzing expenses and habits
For similar cases, here are some examples:
> https://business.ingello.com/platforma - a product platform with complex logic and phased development
> https://business.ingello.com/vorfahr - an example of SaaS and automation, where architecture, data, and scalability are important
> https://systems-fl.ingello.com - the main profile of Ingello Systems for projects on the exchange
Please clarify two points:
> Is the application starting only on iOS, or do we need to prepare the foundation for Android as well?
> Is the integration of banks planned through a specific service, or do we need to help choose the right one for now?
Look, there’s a nuance - if the design is already ready in Figma, then the first stage can be streamlined, and we can quickly assemble a live skeleton and then calmly add functions. A shoemaker without shoes is not needed here - it’s better to check the architecture at an early stage than to fix financial logic in production later.
