How it works
Pick a ticker and a threshold — price, %, RSI, volume spike. In plain English.
We monitor the market every minute. The instant your rule triggers, we fire an alert.
Straight to your phone, even when the app is closed. No spam.
Features
Not just "the stock moved" — but why it moved, what it means, and what to watch next.
Define the trigger — price, volume, a technical break. We notify you only when it really happens.
RSI, MACD, support and resistance, intraday context, and a comparison against the broader market.
We link the headlines that moved a stock to the move itself, so you understand the why.
The moment a director or officer buys or sells — straight from SEC Form 4 filings. The signal everyone watches, pushed to you.
US equities and ETFs, same interface, same depth of analysis.
Install to your home screen in two taps. Works even when the app is closed — no App Store needed.
Quiet hours, pause, filtering by ticker and sector. You decide when notifications reach you.
Why now
TradingView, Discord groups, broker apps — all reactive. You open them when you notice something already happened. Sonar runs in the background and pings your phone the moment a condition you defined actually triggers.
