About FundsIndia

FundsIndia is an online investment platform run by Wealth India Financial Services, a Chennai company. It launched in 2009 with mutual funds and later added corporate fixed deposits and equity investing, so retail investors can manage several asset classes in one account. Its mobile app is the main way many of those investors check their portfolio and place orders.

The challenge

The existing iOS app had grown on a legacy codebase that was slowing the product team down:

• Technical debt. Years of additions made each new feature harder and riskier to ship.
• Performance and engagement. The app felt slow, and engagement lagged behind what the business needed from its mobile channel.
• A disconnected experience. Mutual funds, stocks and fixed deposits did not feel like one product, even though customers held all three.
• No safety net. There was no automated test coverage and no performance monitoring, so regressions were found by users.

What Appmetry built

Appmetry rewrote the FundsIndia iOS app from scratch in Swift instead of patching the old code:

• One investing experience. Mutual funds from leading Indian fund houses, BSE stock trading and corporate fixed deposits sit in a single, consistent app.
• Portfolio visualisation. Graphs make holdings and performance easy to read on a phone.
• Clean architecture. A modular Swift codebase that the FundsIndia team can extend without reopening old problems.
• Quality built in. Test-driven development with unit test coverage, plus performance monitoring and engagement analytics so the team can see how releases behave in production.

How we worked

The rewrite ran as a full engagement with daily communication with the FundsIndia product team, which they called out in their feedback. Building test coverage alongside the features meant the new app could ship with confidence rather than relying on manual regression passes.

The outcome

The new Swift app serves more than a million users. FundsIndia's product team reported that the redesigned app brings in more customers and has better engagement.

What this shows

For a fintech app, a rewrite pays off when the old codebase blocks both speed and reliability. Combining the rewrite with test coverage and analytics is what turns it into a lasting improvement rather than a one-off redesign. See our mobile app development service for how we approach rewrites like this.
