Airside Sync (previously "Atlas") is a digital platform for reporting SNOWTAM according to ICAO’s Global Reporting Format (GRF) guidelines. The assessment is noted in an app and can accommodate unlimited simultaneous reporters, viewers or users. All the reported assessments are then automatically compiled into a single SNOWTAM-report and can be sent directly to any chosen recipient or authority. Safe Sky Airside Sync also offers you a decision support system because the regulatory framework around the new SNOWTAM-reporting format (GRF) is incorporated in the app. Based on the observed and registered condition the app will suggest the adequate RwyCC (Runway Condition Code), as well as available up- or downgrades and the criteria for each.

Verdict
The clearest difference is in-app purchases: Safe Sky at none against WindCheck's 2. WindCheck's advantage is update cadence (every 6 days vs every 6 weeks). On price, ads, device support and iOS requirement there is nothing between them.
