Fomo App Referral Code JOIN100 – Apply the Main Code and Save 10% on Every Trade
What is the FOMO app referral code? It is JOIN100 — enter it when you create your Fomo account and every trading fee drops from 0.50% to 0.45%. This guide shows exactly where to apply the code, how much you save on real trade sizes, and what to check if the discount does not appear.
The Fomo app referral code is JOIN100. You type it into the referral field when you create your Fomo account, and from that moment every trading fee you pay drops by 10% — from 0.50% down to 0.45% per trade. Claim it through this link: https://fomo.family/r/JOIN100.
That step takes about five seconds. It costs you nothing, it changes nothing about how you trade, and it keeps reducing your fees on every swap for as long as you use the app. This guide shows you exactly where the code goes, what your account looks like before and after, what you save on realistic trade sizes, and what to do if the discount does not appear right away.
If you want to run your own numbers first, the copy trading fee calculator lets you enter your trade size and frequency and see the difference between 0.50% and 0.45% instantly.

What the Fomo app does
Fomo is a mobile-first trading app built for fast-moving crypto markets. Its core feature is copy trading: you follow experienced wallets, and when they buy or sell a token, your account mirrors that move automatically. Instead of watching charts all day and copying trades by hand, you pick the traders you trust, set your budget, and let the app execute.
The app is especially popular with traders who focus on new token launches on chains like Solana and BNB Chain, where prices move in seconds and manual copying is often too slow. Execution speed, one-tap entries, and built-in risk controls are the reasons traders stay. The full Fomo app review covers the features in detail, and the copy trading explainer walks through how mirroring a wallet actually works.
Every trade the app executes for you carries a fee. That fee is where JOIN100 comes in.
What the JOIN100 code changes
The standard trading fee on Fomo is 0.50% of each trade. When you sign up with the referral code JOIN100, that fee drops by 10%, so you pay 0.45% instead. The discount applies to every trade, on every market, for as long as your account stays active.
Nothing else changes. The same tokens, the same copy trading features, the same speed. You simply keep 10% of what you would have paid in fees.
| Fee | Without code | With JOIN100 | |
|---|---|---|---|
| Fee per trade | 0.50% | 0.45% | |
| Fee on a $1,000 trade | $5.00 | $4.50 | |
| Fee on a $5,000 trade | $25.00 | $22.50 | |
| Fee on a $10,000 trade | $50.00 | $45.00 |
Where exactly you enter the code
The code field appears during signup — not inside the app after you already have an account. Follow this order and you cannot miss it:
- Open the referral link https://fomo.family/r/JOIN100 — it pre-fills the code for you, so this is the safest route.
- If you are installing the app manually instead, download Fomo and start creating your account.
- On the signup screen, find the field labeled referral code, invite code, or promo code.
- Type JOIN100 exactly — capital letters, no spaces, no extra characters.
- Finish creating your account.
- Before your first trade, check that the fee shown on a trade preview reads 0.45%, not 0.50%.
The most common mistake is skipping step 3 because the field is optional or folded under a link like *I have a code*. If you finish signup without entering the code, the 0.45% rate never activates on that account.
Signup checklist
Run through this list before you confirm your account, and the discount will be locked in from your very first trade:
| Step | What to check | Why it matters | |
|---|---|---|---|
| 1 | Open https://fomo.family/r/JOIN100 | The link applies the code automatically | |
| 2 | The code field shows JOIN100 | A typo here silently removes the discount | |
| 3 | No extra spaces before or after the code | Leading spaces make the code invalid | |
| 4 | Account fully created before trading | The code only binds at signup | |
| 5 | First trade preview shows 0.45% | This is the proof the discount is active |
How much you actually save
The 0.05% difference looks small on paper, but copy trading means many trades. Active followers might execute 20 to 60 trades per month across several wallets. The table below shows what that adds up to.
| Monthly volume | Saved per trade | Trades per month | Saved per month | Saved per year | |
|---|---|---|---|---|---|
| $5,000 | $2.50 | 20 | $50 | $600 | |
| $10,000 | $5.00 | 30 | $150 | $1,800 | |
| $25,000 | $12.50 | 40 | $500 | $6,000 | |
| $50,000 | $25.00 | 60 | $1,500 | $18,000 |
Read the second row slowly: a trader moving $10,000 per month across 30 trades pays $1,350 in fees with the code instead of $1,500 without it. That is $1,800 per year for typing six characters once. The fee calculator reproduces this math for any volume you enter.
Savings compound in a second way too. Every dollar not paid in fees stays in your balance and keeps working, so the real benefit is slightly larger than the table shows.
Who benefits most from JOIN100
The code is worth applying for everyone, but the payoff is biggest for three groups:
- High-frequency copy traders. If you follow several active wallets, your trade count climbs fast, and fee savings scale directly with trade count.
- Large-account traders. On big positions, 0.05% per trade is real money — $45 versus $50 on a single $10,000 swap, every time.
- New traders. Signing up with JOIN100 from day one means you never pay the higher rate, and the savings quietly accumulate while you learn.
If you trade only two or three times a year, the discount saves a few dollars — still worth it, but the main reason to use the code is that it costs nothing and expires never.
What happens if you sign up without a code
Without the code, nothing breaks. Your account works normally, you pay the standard 0.50% fee, and the app behaves exactly as it would for anyone else. You simply miss the discount.
The frustrating part is that most people do not notice. A 0.50% fee feels normal because it is what the app shows by default. You only realize the difference when you compare accounts side by side. That is why the fee check on your first trade preview matters — it is the one moment where the difference is visible before money is on the line.

Fomo compared with other copy trading apps
Fomo is not the only app in this space. Here is how the main options compare, including the referral codes for each:
| App | Referral code | Fee benefit | Best for | |
|---|---|---|---|---|
| Fomo | JOIN100 | 10% off, 0.50% → 0.45% | Fast copy trading, mobile | |
| Axiom | rebatehq | Referral rewards | Solana power users | |
| Runnr | TRADEHQ | 10% off | Mobile-first trading | |
| GMGN | COPYHQ | Referral rewards | New token discovery | |
| Photon | COPYHQ | Referral rewards | Solana sniping |
Each link and code is covered on the tools page, along with the fee structure of every platform so you can compare them properly.
Mobile vs desktop signup
Fomo is designed as a mobile app, and most people sign up on their phone. The flow is identical on both:
- Mobile: open the referral link, the app store page or in-app signup appears with the code applied, then finish registration. This is the smoothest path.
- Desktop or tablet: if you start on the website, complete registration there and install the app afterward — the code carries over with the account, not the device.
One warning: do not start signup in one browser, abandon it, and finish in another. If the first attempt already created an account without the code, that account is the one that exists. Always complete registration in one sitting, starting from the referral link.
Common mistakes and fixes
Most problems with the code come down to one of these five issues:
| Problem | Cause | Fix | |
|---|---|---|---|
| Fee still shows 0.50% | Code was not saved during signup | Contact support with your signup details | |
| Code field says invalid | Typo, space, or lowercase entry | Re-enter JOIN100 exactly | |
| Field was missing | The optional code link was skipped | Use the referral link instead of manual signup | |
| Signed up twice | First account already exists without the code | Use the original account, ask support about the code | |
| Discount stopped showing | Logged into a different account | Confirm you are on the account created with JOIN100 |
Risk-management tips for new copy traders
The referral code lowers your costs, but good habits protect your capital. Four rules worth following from week one:
- Start small. Copy with an amount you can afford to lose entirely while you learn how each leader trades.
- Diversify leaders. Following three wallets with different styles is safer than putting everything behind one hot streak.
- Watch the fee drag. Even at 0.45%, many small trades erode returns. Fewer, larger, better-chosen copies usually beat constant churn.
- Set stop levels. Use the risk controls in the app so a single bad leader cannot take your whole budget down.
Costs and risk management together are what separate traders who last from traders who burn out in a month.
Your first week with JOIN100
A simple plan for the seven days after signup:
| Day | Action | Goal | |
|---|---|---|---|
| 1 | Sign up via https://fomo.family/r/JOIN100 | Account created with 0.45% fees | |
| 2 | Verify the fee on a trade preview | Confirm the discount is live | |
| 3 | Research three leaders with solid track records | Build a watchlist | |
| 4 | Copy your first small trade | Test execution end to end | |
| 5 | Review fills, fees, and slippage | Understand your true costs | |
| 6 | Adjust budget allocation per leader | Balance your risk | |
| 7 | Compare your fee total with the 0.50% math | See the savings in your own numbers |
By day seven you will have real data on how the app behaves with your money, and the fee discount will already be working in the background.

Is the Fomo app free to use?
The app is free to download and use. You pay the trading fee on each executed trade — 0.45% with the code instead of 0.50% without it.
Where do I type the referral code?
On the signup screen, in the field labeled referral code, invite code, or promo code. It is sometimes tucked under a link that says I have a code, so expand it before finishing.
Can I use JOIN100 on iPhone and Android?
Yes. The code works on both platforms and on any device, because it binds to your account, not your phone.
I already have a Fomo account. Can I still apply the code?
Try entering it in your account settings under referral or promotions — some accounts can still apply a code. If the option is not there, contact support and ask them to attach JOIN100. The most reliable path is always applying it at signup.
What if the code does not work?
Check for typos, spaces, or lowercase letters first — the code must read JOIN100 exactly. If the field still rejects it, sign up through the referral link https://fomo.family/r/JOIN100, which applies the code automatically, and verify the 0.45% fee before trading.
How do I check that the discount is active?
Open a trade preview before confirming any swap. The fee line should read 0.45%. If it still shows 0.50%, the code is not active on your account.
Does the 10% discount expire?
No. Once the code is applied at signup, the reduced rate stays on your account for every trade.
Does using the code change anything else in the app?
No. Features, markets, speed, and withdrawal rules are identical. The only difference is the lower fee.
Can I combine JOIN100 with other promotions?
Occasional platform promotions can stack on top of your referral discount. Check the promotions tab in the app for anything currently running.
Is Fomo safe for copy trading?
The app is widely used and includes built-in risk controls, but copy trading always carries risk: you lose money when the leaders you follow lose money. Start small and diversify.
What happens if I refer friends with my own link?
Once your account is active, the app gives you your own referral link so you can earn rewards when friends sign up through it.
