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 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.

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:

We have experience in developing fintech solutions with integration of banking APIs and crypto wallets. We implement the project through a modular architecture, which will allow you to start with an MVP and gradually scale the functionality using an already prepared design. We suggest focusing on data security and transaction stability. We are ready to discuss the details of implementing the application skeleton.
