App Development for Financial Services Firms

Only if clients will open it often. An investor who checks a portfolio weekly, a borrower who pays an instalment each month, a policyholder who files claims or a customer of a payments product has reason to keep an app. A client who meets an adviser twice a year does not, and a secure web portal that works well on a phone serves them better at lower cost.

Apps bring continuing obligations: yearly updates for new operating system versions, store reviews for every release and security upkeep. A firm should take that on because the app is central to how it serves clients, not because competitors have one.

We ask how often and for what before recommending either route. Where a portal is the better answer, it is described on our software development for financial firms page.

More than of most apps, and they enforce it. Both Apple and Google expect an app that offers financial services to be published by the licensed or registered entity itself, or with documented authorisation, and to state clearly who provides the service. Personal data use must be disclosed accurately in the store listing.

Lending apps face the closest scrutiny. In India, Google Play requires personal loan apps to complete a declaration and provide proof of the lender's licence from the Reserve Bank of India, or of the arrangement with a licensed lender, and it restricts such apps from accessing contacts, photographs and precise location. Loan terms such as the repayment period and the maximum annual cost must be disclosed in the listing.

We prepare the listing, the declarations and the supporting documents with your compliance team and plan time for review, since first submissions of financial apps often draw questions. Trying to slip past these rules leads to removal from the store, which for an app-based business is fatal.

As little as the service needs, with consent for each purpose. This is good practice everywhere and a rule in several places. The Reserve Bank of India's directions on digital lending say that data collection by lending apps must be need-based and with the borrower's explicit consent, and they bar access to phone resources such as the contact list, call logs and media files, with one-time access to the camera, microphone or location allowed only for onboarding and identity checks.

India's Digital Personal Data Protection Act requires clear notice and consent, and gives people the right to withdraw it and to have data erased. In the United States, the Gramm-Leach-Bliley Act governs how financial institutions share customer information, and state privacy laws add rights for residents.

We request each permission only at the moment a feature needs it, explain why in plain words and make the app work when a non-essential permission is refused. Third-party kits for analytics or advertising are kept to a minimum, since each can send data elsewhere. Users can view and delete their data from inside the app, as both stores require.

By assuming the phone will be lost, shared or compromised. The app locks behind the device's fingerprint or face unlock, with a passcode fallback, and locks again after a short time in the background. Sensitive values are stored in the phone's secure storage, and nothing confidential is written to logs.

Screens that show balances or personal details are hidden in the app switcher and, on Android, protected from screenshots where appropriate. The app checks that it is talking to the genuine server. Sessions expire, and a customer can sign out other devices. Actions that move money or change contact details require the customer to confirm again.

Notifications need thought. A message on a lock screen that shows a balance or a loan status can be read by anyone nearby, so alerts say that there is an update and reveal the detail only after unlock. Before launch, an independent security assessment of the app and its servers is strongly advisable, and we work with the assessor you appoint.

In short steps that can be resumed, with the regulated check done by a licensed provider. Customers abandon long forms on a small screen, so the flow asks for one thing at a time, saves as it goes and explains why each item is needed.

Documents are captured with the camera with guidance on framing and glare, and the identity verification, whether database checks, document validation or a video process where the rules permit one, is carried out by a specialist provider through its software kit. Your systems receive the result and keep the minimum your rules require.

The sequence of checks, the consents taken and the records kept are set by your regulator and specified by your compliance team. They differ between a mutual fund investment, a loan and an insurance policy, and between India and the United States. We build what is specified and keep a record of each consent with its wording and time.

Through licensed institutions, never directly. In India, collections commonly run over UPI, cards and net banking through a payment aggregator authorised by the Reserve Bank, and recurring payments use the mandate mechanisms the banks and the payments corporation provide. In the United States, card and bank payments run through a processor, and account connections through an established aggregator.

Card details are entered into the provider's own secure fields, so they never touch your servers, which keeps your obligations under the card industry's security standard small. Each transaction is confirmed to the customer on screen and by message, and every state, including failures and reversals, is handled explicitly.

Holding customer funds, issuing accounts or cards and lending all require licences or a partnership with a licensed institution. That arrangement is yours to make, and it should be settled before the app is designed, because the partner's requirements shape the product. In the United States, a company that is not a bank must say so clearly and describe any deposit insurance accurately.

With clarity above all. Money makes people anxious, and an interface that is ambiguous about an amount, a date or what a button will do loses them. Every figure is labelled. Every action that cannot be undone says so before it happens. Charges are shown before the customer agrees, not after.

Language is plain and, in India, often needs to be available in Hindi and regional languages for the product to reach its audience. Dates, currency and number formats follow local convention, including the Indian system of lakhs and crores where customers expect it.

Accessibility is part of trust. Every control is labelled for screen readers, text scales with the phone's setting, contrast is sufficient and nothing depends on colour alone. We test with VoiceOver and TalkBack. Disclosures required by your regulator are shown where the customer will actually see them, in wording your approver supplies.

Cautiously. A bug in a game is an annoyance. A bug in a financial app can show a customer the wrong balance. Every change goes through code review and automated tests, then testing on a range of real devices with test accounts and sandbox payment credentials.

Releases reach a small percentage of users first while crash reports and key measures are watched, then widen. Features can be switched off remotely without a new release if something misbehaves. The server side keeps older versions of the app working for a time, since customers do not all update at once, and can require an update when a security fix makes it necessary.

Apple and Google release new operating systems every year, and the app must be updated to stay listed and to work well. We offer a monthly plan covering monitoring, platform updates, security patches and small improvements, with every release approved by you.

It begins with a discovery of two to three weeks with your product, compliance and security people. We define the smallest useful version, map the regulations and store rules that apply, choose the providers and produce a specification, a clickable prototype and an estimate. Our guides to planning an MVP and app development cost in India explain how scope drives time and cost.

For most financial apps we recommend a cross-platform framework to cover iPhone and Android from one codebase, with native code where security features need it. Development runs in two-week cycles, each ending with a build on your phone. Developer accounts are in your company's name, and the code and all rights are yours.

The server behind the app is covered on our software development for financial firms page, and the public site on website development for financial firms. The industry overview is on our financial services page, and our general method is under app development.
