# FX Position Size Calculator vs Forex Backtest

The clearest difference is rating: FX Position Size Calculator at 4.7 against Forex Backtest's 2.3. FX Position Size Calculator also leads on ratings volume (227 vs 6). Forex Backtest's advantage is ads (none vs shown) and update cadence (every 5 days vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. FX Position Size Calculator sells 1 one-off in-app purchase and Forex Backtest sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

FX Position Size Calculator holds the better App Store score, 4.7 against 2.3. That said, the two scores are not equally well evidenced: FX Position Size Calculator has 227 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 38% of FX Position Size Calculator's written reviews are positive against 57% of Forex Backtest's, so the app with the better star average is not the one people write more warmly about.

FX Position Size Calculator ships an update monthly, Forex Backtest every 5 days. The most recent releases landed on October 2, 2026 and October 1, 2026 respectively.
