Verdict

The call

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). Withings's advantage is review sentiment (25% vs 10%) and update cadence (fortnightly vs every 5 weeks). On price, ads and device support there is nothing between them.
