Verdict

The call

The clearest difference is ads: Netatmo Weather at none against Klart's shown. Netatmo Weather also leads on ratings volume (1.6K vs 184). Klart's advantage is update cadence (weekly vs every 2 months) and monetization model (ad-supported vs free with in-app purchases). On price, rating, review sentiment and in-app purchases there is nothing between them.
