Before you trade it, Backster it. Describe a trading idea in plain English and Backster turns it into a real, runnable strategy โ then shows you exactly how it would have played out on years of historical crypto data. No exchange account, no real money, nothing to lose but a bad idea. DESCRIBE IT, DON'T CODE IT Say it the way you'd think it โ "buy when RSI drops below 30, take profit at 5%" โ and Backster writes the real strategy code behind it. It's production-grade Freqtrade, the same open-source framework serious crypto traders use, not toy snippets. No programming required. YEARS OF DATA, ANSWERED IN SECONDS Backtest any strategy against years of real historical crypto markets in seconds. See every trade it would have made โ the wins, the losses, and whether the idea actually holds up โ before you ever risk a cent. WATCH IT TRADE, RISK-FREE Turn a strategy into a paper bot: a fully simulated trader that runs on live market data and shows you how it would perform in real time. All simulation, always. Never a dollar of real money. TEST EVERYTHING, RISK NOTHING Backster is built for learning. Test, tweak, and compare as many ideas as you want, and build real intuition for how strategies behave without ever putting money on the line. PLANS Backster is free to start. Pro, Max, and Ultra unlock a higher monthly usage allowance and 1, 3, or 6 concurrent paper bots. Subscriptions bill monthly through your Apple Account and renew automatically until cancelled in Settings. IMPORTANT Backster is an education and simulation tool. It is not a broker, does not connect to exchanges, does not execute real trades, and does not provide financial advice. Past (simulated) performance does not guarantee future results.

Verdict
The clearest difference is in-app purchases: MyYields at none against Backster's 6. MyYields also leads on iOS requirement (15.6 vs 18.6). Backster's advantage is update cadence (weekly vs fortnightly). On price, ads and device support there is nothing between them.
