# Lightspeed App vs ACE

The clearest difference is review sentiment: ACE at 80% against Lightspeed App's 12%. ACE also leads on rating (5.0 vs 3.3). Lightspeed App's advantage is ratings volume (49 vs 5) 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. Neither carries in-app purchases, so what you see is what you pay.

ACE holds the better App Store score, 5.0 against 3.3.
