# SymPlayer vs Slo Mo

The clearest difference is rating: SymPlayer at 5.0 against Slo Mo's 3.8. SymPlayer also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 10 days vs every 4 months). Slo Mo's advantage is ads (none vs shown) and ratings volume (2.9K vs 3). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SymPlayer sells 3 in-app purchases, starting at $0.99 per month and Slo Mo sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SymPlayer holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Slo Mo has 2.9K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 91% of SymPlayer's written reviews are positive against 69% of Slo Mo's.

SymPlayer ships an update every 10 days, Slo Mo every 4 months. Both last shipped on November 6, 2026.
