Snapper

Snapper is the iOS companion for the Snapper trading platform — a native SwiftUI app that lets you watch positions, place orders, attach stops, and respond to alerts from your phone, against the backend you configure and control.

WHAT IT DOES

• View live positions, orders, executions, and balances across multiple wallets and exchanges. • Place market and limit orders, attach stop-loss and take-profit brackets, and configure trailing stops — all with reduce-only safety on close-out flows. • Receive instant push notifications for fills, stop-loss triggers, system warnings, and alert routing rules you control per-device. • Manage alert preferences with per-(alert type, scope) overrides — quiet hours, mute timers, and minimum priority. • Switch between live and paper trading modes; the app surfaces the (paper) tag everywhere a wallet is referenced so the two modes are never confused. • Time-travel: replay historical bus state to inspect what your strategies saw at a given moment.

WHO IT'S FOR

Self-directed traders who run their own Snapper backend. The app is a thin client; it expects a Snapper-compatible API on the URL you configure. If you don't already run a Snapper backend, this app won't be useful to you on its own.

PRIVACY

Snapper is open source (MIT) and ships zero third-party SDKs — no analytics, no ad networks, no crash-reporting libraries. The app talks only to the backend you configured and to Apple Push Notification service (for alerts you opted into). Source code is at github.com/mateusz-klatt/snapper-ios. Privacy policy: snapper.ch/privacy-policy.html.

REQUIREMENTS

• A running Snapper backend (you provide the URL during sign-in). • iOS 26 or later. iPhone only. • Push notifications are optional; the app is fully usable without them.

NOT FINANCIAL ADVICE

Snapper is a trading interface, not a trading strategy. The app does not provide market analysis, trade recommendations, or financial advice. Markets carry risk; trade what you can afford to lose.
