Verdict
The clearest difference is rating: Opti Train at 5.0 against 8's 4.3. 8's advantage is monetization model (free with in-app purchases vs subscription) and review sentiment (67% vs 33%). On price, ratings volume, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 8 sells 10 one-off in-app purchases and Opti Train sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Opti Train holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 67% of 8's written reviews are positive against 33% of Opti Train's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on June 6, 2026 and September 10, 2026 respectively.
