# Previews Creator vs SEM

The clearest difference is review sentiment: Previews Creator at 100% against SEM's 38%. Previews Creator also leads on rating (5.0 vs 3.4). SEM's advantage is in-app purchases (none vs 3) and update cadence (every 2 weeks vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Previews Creator sells 3 one-off in-app purchases. SEM asks for nothing beyond the download.

Previews Creator holds the better App Store score, 5.0 against 3.4. Both are backed by a comparable volume of ratings — 3 and 11 respectively. Written reviews point the same way: 100% of Previews Creator's written reviews are positive against 38% of SEM's.
