How it works

Three steps. We handle the rest.

01

Define a rule

Pick a ticker and a threshold — price, %, RSI, volume spike. In plain English.

02

We watch the market

We monitor the market every minute. The instant your rule triggers, we fire an alert.

03

You get notified

Straight to your phone, even when the app is closed. No spam.

Features

The tools that help you understand the market

Not just "the stock moved" — but why it moved, what it means, and what to watch next.

Precision alerts you actually want

Define the trigger — price, volume, a technical break. We notify you only when it really happens.

Real technicals on every ticker

RSI, MACD, support and resistance, intraday context, and a comparison against the broader market.

News tied to the move

We link the headlines that moved a stock to the move itself, so you understand the why.

Insider-trade alerts

The moment a director or officer buys or sells — straight from SEC Form 4 filings. The signal everyone watches, pushed to you.

Stocks and ETFs in one place

US equities and ETFs, same interface, same depth of analysis.

A real app on your phone

Install to your home screen in two taps. Works even when the app is closed — no App Store needed.

Full control over alerts

Quiet hours, pause, filtering by ticker and sector. You decide when notifications reach you.

Why now

Charts tell you what happened. Sonar tells you the moment it starts.

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.

Without Sonar
  • Open TradingView, scan 20 watchlists
  • Spot the move 15 minutes late
  • Read 3 Discord channels for context
  • Move already played out
With Sonar
  • Define the conditions once
  • Phone pings the second it triggers
  • Tap the alert — see price, volume, news context
  • Decide while the move is still live

Testimonials

Traders who switched to Sonar

Stock and ETF traders who stopped watching charts all day.

I used to miss breakouts constantly. Now Sonar catches them while I sleep.

Daniel K.

Swing Trader

The volume spike alerts alone paid for the subscription in the first week.

Maya R.

Finally an app that explains WHY the stock moved, not just that it moved.

FAQ

What you'll probably ask

No. Sonar is an information tool — we surface market data and analysis but never give buy/sell recommendations. The final decision is always yours.

US stocks and ETFs (NYSE, NASDAQ, OTC) — thousands of tickers, from mega-caps to smaller names. All from a single dashboard.

After signing up, go to your dashboard, pick a ticker, choose a condition (price, volume, RSI, etc.), set the threshold, and save. You'll get notified the moment it triggers — usually within seconds.

Official market data providers. Prices stream continuously during trading hours.

Yes. Cancellation is self-service from your settings — no call required. We also offer a no-questions full refund on any new charge within 7 days.

Yes. Standard encryption in transit and at rest. We never store credit card details (Stripe does that) and we have no access to your brokerage.

Yes. The interface is bilingual (English / Hebrew). We cover US stock and ETF markets — which you can track from anywhere in the world.

Pro covers price tracking, volume alerts, and AI analysis with news context. Alpha adds the full technical suite — RSI, MACD, EMA crossovers, support and resistance breaks, and insider transaction tracking. Active traders who rely on technicals pick Alpha.
