# ReTrader vs 66 Days

The clearest difference is rating: 66 Days at 4.8 against ReTrader's 3.0. 66 Days also leads on update cadence (every 10 days vs every 2 months) and ratings volume (258 vs 2). ReTrader's advantage is review sentiment (82% vs 50%) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ReTrader sells 10 one-off in-app purchases and 66 Days sells 2 in-app purchases, starting at $15.99 per month. Whichever you choose, the download price is not the number that matters.

66 Days holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: 66 Days has 258 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of ReTrader's written reviews are positive against 50% of 66 Days's, so the app with the better star average is not the one people write more warmly about.

ReTrader ships an update every 2 months, 66 Days every 10 days. The most recent releases landed on October 29, 2026 and October 23, 2026 respectively.
