# sDrives vs Siemens Event

The clearest difference is rating: sDrives at 4.5 against Siemens Event's 3.0. sDrives also leads on review sentiment (100% vs 67%) and ratings volume (27 vs 2). Siemens Event's advantage is in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. sDrives sells 1 one-off in-app purchase. Siemens Event asks for nothing beyond the download.

sDrives holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: sDrives has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of sDrives's written reviews are positive against 67% of Siemens Event's.

sDrives ships an update every 2 months, Siemens Event every 2 weeks. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
