Every broker eventually asks for their own mobile app. The reasoning is sound: clients live on their phones, the platform vendor’s app carries someone else’s logo, and a branded icon on a trader’s home screen is worth something. Then the project meets Apple’s review team and the timeline doubles.
Here is what the options actually are, what the app has to do, and where submissions get rejected.
Three ways to put a trading app in your name
The first option is to not have one. Your clients download the platform vendor’s app and select your server. This costs nothing, carries no store risk, and gives you no branding at all. For a new brokerage with a small book, it is often the right call for the first year.
The second is a white label mobile app from your platform vendor, published under your company. Several platform providers offer this. You get your name and colors on a proven trading terminal, and you inherit the listing, the review process, and the update cycle. The build cost is low and the ongoing obligations are real.
The third is a custom app built on your CRM and trading APIs. This is the only route where the app can do everything a client needs in one place: register, upload documents, fund the account, open a new trading account, and see balances alongside the chart. It is also the most expensive to build and the only one where you own every rejection.
Worth being blunt about the third option: for most brokers the trading terminal is not the differentiator. Traders who care about charting already have MetaTrader or cTrader installed and are not going to switch to your version of a candlestick. The part of the experience that is genuinely yours is the account area, which is why many custom apps handle onboarding, funding, and account management and hand the actual trading screen off to the platform app.
What the app has to do besides show charts
Scope creep kills these projects, so decide early which of these are in version one:
- Registration and login, ideally shared with your web client area so a client is not maintaining two identities.
- Document upload using the phone camera, which is the single biggest reason mobile onboarding beats desktop onboarding on completion rate.
- Deposits and withdrawals, including whichever local methods your regions actually use.
- Account list, balances, leverage, and platform credentials.
- Push notifications for margin levels, document approvals, and payment status.
That list describes a trader’s room in an app shell, which is exactly what it should be. If the same data already powers your web portal, the mobile build is an interface project rather than a platform project. The CRM API is what a mobile developer builds against, and it is worth checking that it exposes everything on the list before anyone writes a line of Swift. Prop firms have a similar list with different contents, since the equivalent screen is the challenge dashboard with rule progress, drawdown, and payout status.
Push deserves a note of its own. It is the reason to build an app at all in many cases, because it is the only channel that reaches a trader without competing with an inbox. Margin calls, verification approvals, and failed deposits are the notifications clients actually want, and they need to fire from the same notification system your CRM already uses rather than from a separate tool nobody maintains.
Getting through Apple review
Four guidelines account for most rejections in this category.
- Guideline 3.2.1(viii) is the one to read first. Apple’s text: “Apps used for financial trading, investing, or money management should be submitted by the financial institution performing such services and must have necessary licensing and permissions in the locations where you make them available.” In practice this means the developer account belongs to your licensed entity, the name on the account matches the name on the license, and your country availability matches where you are actually authorized. An app submitted by a development agency on your behalf is asking for a rejection.
- Guideline 4.3(b) covers apps that are “indistinguishable from what’s already widely available.” Branded variants of the same trading terminal sit uncomfortably close to this line, which is why per broker clones of a well known platform have been a difficult route for years. The defense is that your app does things the generic one does not, which is another argument for building the account area rather than another chart screen.
- Guideline 4.2 catches thin apps. If your submission is a web view wrapper around your client portal with nothing native in it, expect to be asked what the app adds over the mobile site. Camera based document capture, biometric login, and push notifications are the usual answers, and they need to be present before you submit rather than promised in the review notes.
- Guideline 5.1.1 requires a privacy policy that names what you collect, how you use it, who you share it with, and how a user deletes their data. Apple also expects account deletion to be available inside the app. For a regulated broker with record keeping obligations this needs a real answer, usually deletion of the app account plus a clear statement of what must be retained by law and for how long.
Two practical things that shorten review: give the reviewer working demo credentials on an account with funds and open positions, and attach a short screen recording of the flow. Reviewers who cannot get past your KYC gate will reject rather than investigate.
The in-app purchase question for prop firms
Prop firms have an extra problem. Guideline 3.1.1 requires in-app purchase for unlocking features or content, and it explicitly rules out using your own mechanism for it. Whether a challenge fee counts as digital content is a question you want answered before you build the flow, not after, because the commission difference is large enough to change your unit economics.
The safe pattern most operators use is to keep challenge purchases on the web and let the app show and manage accounts the trader already owns. Apple’s rules on linking out to external purchases have changed several times in recent years and differ by region, so read the current guideline text rather than a blog post from two years ago, this one included.
Google Play
Play is generally faster but has its own paperwork. Any app with financial features has to complete the Financial features declaration in Play Console, and the Financial Services policy sets additional requirements that vary by country, including licensing documentation in some markets. Fill the declaration in honestly the first time, because corrections after a rejection are slower than the original review.
You will also need a completed Data safety section that matches your privacy policy, and you should plan for Google’s target API level requirements, which force a technical update every year whether or not your product has changed.
One more thing worth checking before you write store copy: advertising rules for complex speculative financial products restrict how you can describe trading in both stores and in ads. Screenshots implying profit are a reliable way to get pulled.
Budget for the second year, not the launch
The build quote is the small number. Every year brings new OS releases, a mandatory API level bump on Android, SDK updates from your platform vendor, and a review cycle for each of them. An app that gets no maintenance budget stops working within about eighteen months and does more brand damage than not having one.
If the maintenance line is not funded, the honest answer is a responsive client area rather than an app. A well built mobile web portal handles onboarding, funding, and account management on a phone, supports web push on most devices, needs no store approval, and can ship an update on the day you decide to make one.
How to decide
Look at what share of your client area traffic is already mobile and what those sessions do. If most of it is checking balances and chasing deposits, an app will help and the scope is clear. If the demand is coming from a sales team who wants something to show prospects, a branded web portal will do the same job for a fraction of the cost.
When you do build, ship the account area first and add the trading screen later if the numbers justify it. Clients rarely ask for an app because they want better charts. They ask because they want their money and their documents one tap away, which fits the pattern we saw when reviewing what traders actually want from a broker.
