Fomo Web App Guide: How to Trade on Desktop at fomo.family

What is the Fomo web app?

The Fomo web app is the browser version of Fomo, the cross-chain crypto trading and social discovery app. Fomo launched it on April 29, 2026, so you can trade from a desktop at fomo.family instead of only on an iPhone or Android phone. According to Fomo, it is not a separate product or a stripped-down companion: it is your existing account on a bigger screen.

That matters if you like to research before you trade. A desktop gives you room for charts, holder data, the social feed and your positions side by side. If you are new here, our homepage explains the Fomo app referral code SMARTUSER and how the 10% trading-fee discount works before you open an account.

Same account on web and mobile

Fomo's Help Center says you sign in on the web with the same Apple ID or Google account you use in the mobile app. You then see the same wallets, cash balance and positions. A trade you open on desktop shows up on your phone, and your following list and notification settings carry over as well.

The important warning: signing in with a different Apple ID or Google account does not open your existing account. It creates a new, separate Fomo account with its own wallets. If your balance looks empty on the web, check which account you used before you deposit anything. If the web shows a sign-up prompt while you are using the right account, Fomo says you can tap through it and it will load your existing account rather than create a second one.

• Go to fomo.family in a desktop browser
• Sign in with the exact Apple ID or Google account you used on mobile
• Check that your balance and positions match the app
• Only then deposit or trade

Signing up on the Fomo web app with a referral code

You can also create a new Fomo account directly on the web. If you want the referral discount, the order matters: a referral is attached when the account is created, and there is no general field to add a code later. Open the invite link fomo.family/r/SMARTUSER in the browser you will use, then sign up in that same browser session. If a code box appears, enter SMARTUSER.

Eligible new users who join with SMARTUSER get a 10% discount on Fomo trading fees. It is a fee discount, not a cash bonus or free tokens. For a step-by-step walkthrough on phones as well, read how to use a Fomo referral code, or go back to the Fomo referral code SMARTUSER page to copy the code.

Funding and withdrawing on desktop

This is the biggest practical difference. Fomo's Help Center states that card deposits, bank deposits and bank withdrawals are currently available in the mobile app only. On the web you deposit by sending USDC to your Fomo wallet and you withdraw to a crypto wallet. Fomo's launch post also says new web users can fund with crypto right away, or download the mobile app to use Apple Pay and debit card onramps.

Your wallet addresses are under Manage account in the account menu (hover over your profile picture), or under Settings, then Account and addresses. Before sending USDC, confirm the network and the full address. Sending an asset on the wrong network is one of the most common and costly mistakes. Our Fomo deposit and withdrawal guide covers those checks in more detail.

Trading tokens on the Fomo web app

Fomo web supports token swaps across Solana, Base, BNB Chain and Monad from one unified USD balance, without bridging or switching chains, according to its launch announcement. Fomo's app store listing also mentions Ethereum and Robinhood Chain, so check the current list in the app before assuming a specific network is supported.

On desktop you trade from the buy and sell panel on a token page. The slippage setting sits behind the Swap settings gear on that panel. Quick Trades is a mobile feature; on the web, one-click trading uses the lightning button on rows in your open positions list, with buy presets in dollars and sell presets in percent, and there is Quick buy on the Discover page at fomo.family/discover. The price impact warning shows every time on the web, while the option to hide it for a token exists only in the app.

Whatever the screen, look at the order preview before you confirm: the token, the amount you expect to receive, price impact and the fee line. Fomo states a standard trading fee, and a referral code lowers it. The full breakdown is in our Fomo app fees explained article.

Social features on a bigger screen

Social discovery is central to Fomo, and the web app keeps it. Fomo lists a social feed of top traders and what they are trading, trending tokens and alerts, leaderboards across different time frames, theses where traders explain why they hold a position, and the ability to follow traders and get notified when they move. Coin pages on web show when theses were written, by whom and how popular they are, plus more holder details.

Following a trader does not copy their trades. Fomo says any trade is still made by you. Treat the feed as a starting point for research, not as advice, and remember that a popular position can still lose value quickly. Our explainer on Fomo social trading looks at those risks.

Perps on Fomo web

Since October 24, 2026, you can trade perpetual futures on Fomo web with the same account as the app. Fomo's perps guide says markets come from the third-party protocols Hyperliquid and Trade[XYZ] and cover crypto, stocks, indices, commodities and pre-IPO markets. Fomo charges 0.05% per perps trade, plus the protocol's own trading fee.

Perps use a separate USDC perps cash balance. On web you move money there with the Transfer to perps cash link in the order panel; Fomo lists a minimum of 5 USDC for the transfer and 15 USDC per position including leverage. Perps are not available in the U.S. or to U.S. persons and may be restricted elsewhere. Leverage can magnify losses and lead to liquidation, so understand margin and liquidation price before using it.

Security settings for the web app

On mobile, Fomo uses your device's Screen Lock and biometrics. The web app has an optional PIN lock under Settings, then Security. Fomo says the PIN is saved to your account, so once it is on, every browser you sign in to asks for it. Multi-factor authentication is shared: turning it on in the app or on the web turns it on for both.

You can export your private keys on the web at fomo.family/export-key. Fomo's own guidance is clear: never share a private key, never type it into another website and never send it to anyone, including support. Use your own computer rather than a shared one, keep your browser updated and bookmark fomo.family instead of clicking links in messages. If you arrive from a link and see Fomo's security warning page, read it before logging in. More on this in our article on whether the Fomo app is safe.

• Turn on multi-factor authentication
• Enable the web PIN lock in Settings, then Security
• Never share or paste your private key anywhere
• Type fomo.family yourself or use a bookmark

Web app or mobile app: which should you use?

Use the mobile app if you want card, Apple Pay or bank funding, bank withdrawals or Quick Trades. Use the web app when you want a larger view for research, the Discover trading table, chart-based perps order management and leaderboards. Because it is one account, many users simply do both: fund on the phone and research on the desktop.

If you have not joined yet, decide on the referral before signing up on either platform. The Fomo app referral code SMARTUSER gives eligible new users 10% off trading fees, and you can apply it by opening the SMARTUSER invite link first.
