# Seri vs Sun Fun Kits BMS

The clearest difference is review sentiment: Seri at 100% against Sun Fun Kits BMS's 25%. Seri also leads on rating (5.0 vs 2.8). Sun Fun Kits BMS's advantage is in-app purchases (none vs 1) and update cadence (every 5 days vs every 4 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Seri sells 1 one-off in-app purchase. Sun Fun Kits BMS asks for nothing beyond the download.

Seri holds the better App Store score, 5.0 against 2.8. That said, the two scores are not equally well evidenced: Sun Fun Kits BMS has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Seri's written reviews are positive against 25% of Sun Fun Kits BMS's.
