How to set up Polymarket price and whale alarms

NotiAlarm is an iPhone and Android app that watches Polymarket for you. It rings like an alarm when a market crosses your price, moves fast, trades unusual volume, nears its end date or resolves. With Pro it also rings on whale trades and on the wallets you follow. You don't need a Polymarket account.

  1. Add Polymarket

    Open Sources, tap +, and pick Polymarket. There's no URL to paste: NotiAlarm checks Polymarket's public market data every minute.

  2. Pick a market and what to watch

    Search for a market, then ring when it crosses a price, moves fast, trades unusual volume, gets close to its end date, resolves, or has its resolution disputed.

  3. Follow the whales

    With Pro, ring on large trades across all markets, one category or one market, or follow a wallet when it opens, adds to, trims or exits a position.

Polymarket alerts questions

Do I need a Polymarket account?

No. NotiAlarm reads Polymarket's public market data. It never connects to a wallet.

Is there a Polymarket whale alert app?

Yes. With Pro, NotiAlarm rings on large Polymarket trades across all markets, one category or one market, with the size, side and price you choose. It can also follow a wallet and ring when it opens, adds to, trims or exits a position.

What counts as a whale trade?

You choose. A whale alarm starts at trades of $10,000 or more, and you can set it anywhere from $1,000 to $250,000, for buys, sells or both.

How fast does it ring?

NotiAlarm checks the markets every minute, so a watch rings within about a minute of the move.

How many markets can I watch?

The free plan includes 1 watch. Pro watches as many markets as you like and adds whale and wallet alarms.

Is NotiAlarm free?

The free plan covers 1 source and 1 alarm with Apple's default alarm sound. Pro adds unlimited sources and alarms, NotiAlarm's alarm sounds and your own uploads. It costs $4.99 a month or $35.99 a year after a 1-month free trial.

Is there an Android app?

Yes. NotiAlarm is on Google Play for Android 10 or later, and on the App Store for iPhone and iPad with iOS 26.1 or later.
