Ratio.you

Ratio.you, styled as Ratio on its own app, is a social prediction market app built for iOS and Android rather than a browser tool or Telegram bot. The pitch is simple: follow traders you rate, see their live positions on Polymarket, and copy a position in a tap instead of building your own thesis from scratch. It sits inside Predicts.guru's Copy Trading category, aimed at traders who want exposure to someone else's read on a market without doing the underlying research themselves.

Since its first attributed fill on 2026-04-30, the builder has routed $6.1M in total volume and sits at #73 on the all-time leaderboard, with $66K attributed over the last seven days. Average fill size of $20 points to a retail crowd tapping in and out rather than desks moving size, and 27 distinct wallets a day keep it running as a crowd product rather than a handful of large accounts.

Getting started means installing Ratio.you on iOS or Android, since the operator does not offer a browser version or a Telegram bot. Inside the app a trader browses other accounts, watches their live positions and picks who to follow before copying any of their trades. The live-positions screen is the core of the pitch: it shows what a followed trader currently holds, and copying one tap sends the same trade under your own account rather than requiring you to place it manually.

Copying a trade routes the order into Polymarket's own order book under Ratio.you's builder code, which is how Predicts.guru's index attributes $66K and the rest of its volume back to this tool rather than to Polymarket directly. Execution and settlement still happen on Polymarket's CLOB, not inside Ratio.you.

The product page does not state whether it holds a trader's funds or private key during that process or simply signs and forwards the order, so a trader should check the app's own wallet setup before funding an account and copying a position.

• Follow specific traders

  Pick individual Polymarket accounts to follow instead of a single fixed strategy, so the mix of markets you're exposed to changes as you add or drop who you track.

• Live position visibility

  See a followed trader's open positions before you copy one, rather than betting blind on a strategy you can't inspect.

• One-tap copy execution

  Mirror a trade in a single tap instead of manually pricing and placing your own order on the book.

Traders new to prediction markets

Following someone else's live positions gives a starting point for markets you don't have time to research from scratch yourself.

Mobile-first casual bettors

The app is built for iOS and Android, suiting someone who trades from a phone rather than at a desk running a terminal.

Small, frequent position traders

Average fill size of $20 fits someone opening or closing small stakes often rather than committing size to a single call.

Traders who want exits mirrored too

Buy share of 76.5% means a meaningful slice of routed volume is traders closing positions, not only opening new ones, through the same app.

Traders wary of desk-sized flow

Anyone uneasy following a whale can look at $20 and 27 to judge whether the crowd here trades in similar size to their own.

Ratio.you's own page does not describe whether it holds custody of a trader's funds or private key while a copied trade executes, or whether it only signs and forwards the order; a trader should confirm this directly in the app's own documentation before connecting a wallet. It carries a verified Polymarket profile, which confirms the builder code is attributed correctly, but that check says nothing about the app's own custody or security practices. The referral share program gives the operator an incentive to grow the number of copiers, worth keeping in mind when reading its own marketing.

• What is Ratio.you?

  Ratio.you is a mobile app for iOS and Android that lets a trader follow other Polymarket accounts, watch their live positions and copy a trade in a tap, routing the order through its own builder code.

• Is Ratio.you safe to use?

  The app does not state whether it custodies funds during a copied trade, and it publishes no fee schedule beyond 2.5%, so check its own terms and wallet setup before connecting an account.

• How much does Ratio.you charge in fees?

  It advertises 2.5%, though its own product page carries no itemized fee schedule; Polymarket's per-market trading fee applies on top and is the same no matter which builder routes the order.

• What are Ratio.you alternatives for copy trading on Polymarket?

  Predicts.guru's Copy Trading category lists other builders that route orders under their own code, letting you compare $66K, $20 and 76.5% across tools before choosing where to route a trade.

• How does Ratio.you work?

  A trader installs the app, follows accounts whose positions they want to see, and copies a trade in one tap; the order then routes into Polymarket's own order book under Ratio.you's builder code.

• Does Ratio.you hold my funds?

  The operator's own page does not say whether it takes custody of funds or a private key while a trade is copied, so confirm the wallet setup in the app itself before funding an account.
