tradicted
Free stock market trading game for iOS and Android.
About
Tradicted is a free stock market trading simulator available on iOS and Android. Built for retail traders who want to practice without risking real money — and without waiting hours for the market to move.
Players start with $100k in virtual cash and trade on real historical market data. Two distinct game modes drive the experience: Classic mode is slow and deliberate — study the chart, adjust your risk, place a trade, and watch a single candle play out before deciding the next move. Lightning mode runs candles continuously, letting players hold up to five long or short positions at once and flatten or close them on demand. Both modes feed into monthly and all-time leaderboards.
The website also hosts a free suite of trading calculators (Kelly criterion, position sizing, risk of ruin, risk/reward) and an Academy section covering trading fundamentals.
Anonymous play is supported from the start. Accounts are only required for the leaderboard.
Built solo with Flutter, Firebase, and Cloud Functions.

We have historically been a very anonymous-based site — weather really didn't require our user to have a significant value exchange with us for a long time such as providing an email address. As that begins to evolve we're able to lean into improved targeting and understanding how best to package the subscription product.
Anonymous-First Audiences Limit Subscription Targeting — Solving Identity Unlocks Growth
Weather.com grew for decades without asking users for an account, which meant no first-party identity data for personalization or subscription targeting. Moving toward signed-in experiences — even softly — unlocks better segmentation, targeted paywalls, and lifecycle emails. For any app that acquired large anonymous audiences, solving the identity layer is the high-leverage next step before any paywall optimization.
We tested a toggle on the top of the application where you could enter a new subscription tier from the top navbar... we almost like discovered new real estate because the design team was really actually like didn't want us to have that topnav.
One Throwaway A/B Test Drove $50M — Paywall Placement Is Underexplored Real Estate
In 2018 Tinder's revenue team ran what seemed like a small A/B test — a toggle in the top navbar pointing to a new subscription tier. It generated roughly $50M. Jeff's lesson: revenue teams underexplore paywall placement. Think of your UI as real estate, and ask where you haven't yet put a door to premium.
There's a play for whatever you're stuck on.

1I built it because I hated waiting hours for setups to form on a paper trading account. Wanted a faster way to practice without burning real money.
