# Withings vs 세라젬 IoT

The clearest difference is in-app purchases: 세라젬 IoT at none against Withings's 3. 세라젬 IoT also leads on iOS requirement (15.0 vs 18.0).

Both are free to download. Withings sells 3 in-app purchases, starting at $9.99 per month. 세라젬 IoT asks for nothing beyond the download.

Withings ships an update fortnightly, 세라젬 IoT every 5 weeks. The most recent releases landed on October 21, 2026 and October 7, 2026 respectively.
