Verdict
The clearest difference is rating: SlowMo at 4.6 against Blast Baseball's 3.1. SlowMo also leads on ads (none vs shown) and review sentiment (60% vs 29%). Blast Baseball's advantage is chart position (#70 vs unranked). On price, in-app purchases, monetization model and device support 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. Blast Baseball sells 2 in-app purchases, starting at $9.99 per month and SlowMo sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
SlowMo holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: SlowMo has 1.7K ratings behind it against 323, so its average is the more settled of the two. Written reviews point the same way: 29% of Blast Baseball's written reviews are positive against 60% of SlowMo's.
Blast Baseball ships an update every 4 weeks, SlowMo weekly. The most recent releases landed on October 1, 2026 and September 30, 2026 respectively.
