Polymarket Alerts

What it is

A phone app that watches public Polymarket data and sends push notifications when something you chose happens. It does not trade, hold a key or ask for a login; each notification opens the market or the user profile on Polymarket, and you act there.

What it can alert on, from the website's feature page and the release notes in the App Store listing, read on 30 September 2026:

• Markets - a price threshold, a percentage move, new comments, and changes of state such as a market closing or resolving.
• Users - any wallet or username, for trades and comments, and since April 2026 deposits and withdrawals. The latest release adds a notification when a followed user's position wins or loses.
• Large trades - every trade above a dollar amount you set, across all markets, plus a "whale accumulation" alert added in August for a wallet building a large position out of small fills.
• Wallets the vendor calls insiders - three patterns: a wallet whose first trade is large, a wallet with only a few trades that suddenly trades large, and a dormant wallet that returns with a large trade. They can be narrowed by market category.
• Resolution - a Disputes screen, and since version 1.36 on 27 September 2026, alerts when a settlement is proposed, disputed or settled.

Around the alerts there is a watchlist, a timeline of closed and resolved markets filtered by topic, a "Discovery" view of top wallets and popular markets, a P&L view for a tracked user, and the list of holders on a market.

Availability

The Terms of Use, last updated 22 March 2026, name no restricted country. The only geographic clause is the usual one: use the app in compliance with applicable law. There is no identity check and no account, because there is nothing to deposit - the app never touches money. It is listed in the US App Store, and the privacy policy says it is not intended for anyone under 18.

us_persons is true on that basis, and it describes the app, not the venue. Reading Polymarket's public data is not the same as being allowed to trade on it: the international venue does not serve US persons, and a US reader acting on an alert is looking at Polymarket US or Kalshi for a venue that will take the order.

Pricing

The website says "Free on iOS and Android", and the download is. The App Store listing, read on 30 September 2026, adds five in-app purchases:

Nothing on the website or in either store says what a tier unlocks. The one clue is a release note from February 2026: the historical trades view for any account is "available to Hobby plan (with limits) and Pro plan (unlimited)". So the free app is limited somewhere, and where the line sits is something you find out inside the app. Google Play lists in-app purchases too; we read the prices from the US App Store only.

Nothing is charged on a trade, because no trade goes through the app. That is what the null fee fields mean here.

Markets & resolution

Polymarket's international venue only - no Kalshi, no Polymarket US, no other venue. Every market and resolution is Polymarket's, settled in USDC on Polygon and resolved through the UMA optimistic oracle; the app resolves nothing.

The Disputes screen is the part that matters for a reader holding a position after the market has stopped trading. A disputed Polymarket proposal is a different process from an undisputed one - a reset, a second proposal, and if that is disputed too, a vote of UMA token holders over several days - and who decides the outcome walks through it. What the app gives you is notice that a market has entered that process. The store copy does not say whether it shows the proposed outcome, the bond or the vote, and we did not open the app to check; for the vote itself, Betmoar's dispute dashboard shows the round.

Integrations

None documented: no API, no webhook and no export on the site or in either store listing. Alerts arrive as push notifications through Apple's and Google's services, which the privacy policy names; the Telegram and Discord links on the site are community channels, added in a February release note as such, not a second delivery route. The iPad build also runs on Apple silicon Macs, which a September release note mentions; there is no separate desktop app.

Limitations

The "insider" label is a heuristic about wallets, not a finding about people. A new, thin or dormant wallet placing a large order fits all three of the app's patterns, and so does a trader who opened a fresh wallet for privacy. The vendor's own feature page says such activity "may indicate" privileged information; read the alert as a size-and-wallet-age filter, not as evidence.

No published line between the free and paid tiers. Five prices and no feature list is not a plan you can compare with anything before installing.

Delivery is not promised. The Terms of Use disclaim accuracy, completeness and timeliness of alerts and state that market data "may be delayed, incomplete, or inaccurate". The status page printed "All Systems Operational" on 30 September 2026; whether it is fed by monitoring or edited by hand is not stated.

One venue, and a phone. Nothing for Kalshi, nothing on the web, nothing a script can consume.

Alternatives

For the wallet reading behind the alerts, Polymarket Analytics and Polysights show it on the web, and Polysights has its own insider finder. OrcaLayer indexes large-trade activity from Polygon with a published filter for farmed volume.
