Fintech app development

TheCheatCode designs and develops fintech apps for iOS, Android and the web: budgeting, online accounting, invoicing and financial management. We built Fintur, an app that forecasts your balance day by day, and the iOS app for Lebak, online accounting on mobile. One team handles product, design, development and launch.

Your questions about building a fintech app.

How much does a fintech app cost?

The price depends on the scope: number of screens, user accounts, payments, admin back office and integrations. For a fintech app, the bank connection and the level of security required also weigh on the budget. The most reliable approach is to start from what you actually need. Our online estimate helps you scope it in a few minutes, then we get back to you with a detailed quote.

Can you connect the app to bank accounts?

Yes, through a licensed bank aggregator and in read-only mode. That is how Fintur works: users authorize access from their bank, and the app cannot carry out any transactions.

How do you protect financial data?

Authentication, encryption, access limited to what is strictly necessary and no sensitive data stored unprotected on the device. These choices are made at the design stage, not at the end of the project.

Should I go native or cross-platform?

Fintur is built natively (Swift) to deliver the most refined iPhone experience, with an Android version. Cross-platform lets you launch faster on both stores. We recommend the approach that serves your product and your budget.

Can you build custom invoicing software?

Yes. For a construction company, we built software to manage job sites, quotes, invoices and reminders, as well as a tool that generates PDF invoices in bulk.
