Hayaiti / iOS for Trading
Native SwiftUI for retail brokers and trading platforms. Real-time quotes plumbed for flaky networks, biometric step-up auth on orders, Apple Pay funding, App Store-review-ready disclosures.
3 recommended ios apps packages for Trading. Pay 50% upfront. Source code yours.
Why this combo
The decisions we made differently — and why they matter for trading specifically.
WebSocket reconnects with backoff, snapshot-then-delta on resume, last-known-tick freshness indicators, gap-fill via REST when the stream drops. Your trader never sees a stale price without knowing it's stale.
Face ID / Touch ID / passcode prompt on every order above a threshold the user sets. Replaces 'are you sure?' dialogs with biometric friction that's both faster and harder to fat-finger past.
ACH funding flows via Plaid + Apple Pay where the broker stack supports it. Reduces the funding-step abandon rate that kills new-account activation in trading apps.
Apple's review of financial apps is stricter than most categories — they want to see disclosures, region restrictions, regulatory entity names, and clear links to risk warnings. We follow Apple's published criteria for financial apps — disclosures, region restrictions, regulatory entity names, and risk-warning links land where reviewers cite rejections.
Price alerts, order fills, margin calls, daily digest — every push template reviewed for jurisdictional disclosure rules. We don't ship a push that says 'AAPL up 5%, buy now' (which is legally an investment recommendation in most jurisdictions).
Lightweight Charts inside SwiftUI via WebView, or native Metal rendering for the hot path — depending on customization needs. We profile on iPhone SE, not just iPhone 17 Pro Max. Your buyers' devices skew older than your team's.

Why Hayaiti
Trading-app iOS is the highest-stakes consumer iOS surface short of healthcare: a single fat-finger order, a stale quote, or a delayed margin notification can cost a real user real money. The build playbook targets financial iOS for retail trader audiences — including the disclosure language Apple's review team flags, the network-failure modes a 4G train ride imposes, and the biometric prompts that stop a careless tap from becoming a 100-share market order. We are NOT a registered broker-dealer, NOT a regulated financial institution, NOT compliance counsel — we ship the app under your regulatory wrapper.

Shape of work
A small fintech needed to connect their internal book to a clearing broker's API and reconcile positions, cash, and corporate actions every night without manual intervention. Their existing approach was a CSV download + Excel macro maintained by one person.
Spec engagement built to set the bar — same playbook a real client gets. Real cases publish after launch with the client’s sign-off.
FAQ
Yes — there are dozens in the App Store. Approval requires you to be either a registered broker yourself OR partnered with one (whose name + license number appear in the app's about screen). We can ship the app; you provide the regulatory entity name. Apple does extra review for financial apps; expect a longer review cycle than a typical app.
Equities/options: Interactive Brokers, Alpaca, Tradier, Drivewealth (white-label brokerage). Crypto: Coinbase Advanced, Binance, Bybit, Hyperliquid. Each integration is the same idempotent + reconciliation pattern we use on the web side.
We wire them into the right places (order tickets, leverage selectors, daily statements, push notifications). Your compliance counsel drafts the actual language. We don't sign off on disclosure wording.
We're iOS-only. If Android is on the roadmap we'll tell you upfront and refer you out. Most retail-trading apps we work with start iOS-only because the buyer base skews iPhone (especially in US + EU markets).
Yes — Plaid for ACH funding flows, Apple Pay for the one-tap UX where your processor supports it. Some white-label brokerage stacks (Drivewealth, Alpaca Broker) have native Apple Pay paths; others require integration via Stripe Connect or similar.
Real-time US equity data via Polygon is $200-2,000/mo+ depending on tier. IEX is cheaper. SIP feed is the most expensive. We architect to minimize your data spend (snapshot-then-delta on the WebSocket, cached delayed quotes for non-active users) but the underlying data feed cost is yours.
Yes — the architecture is designed around it. Local cache of last-known prices, write-ahead order queueing for submitted-but-not-confirmed orders, reconnect with sequence-number validation on resume. Your trader gets a clear 'connection restored, here's what changed' state, not silent staleness.
Start with an audit, or jump straight to pricing. Either way, you talk to engineers — not a sales funnel.
