KWTD
Read full descriptionHide full description
Prepare for unexpected situations with short lessons and practice questions available on your device. Lessons and practice progress work offline; external reference links require an internet connection. KWTD brings emergency-preparedness topics into one place, with lessons covering situations such as fire, flooding, power outages, evacuation and first aid. Review the source references and check the guidance that applies where you live. Practice what you learn with assessments and track your progress through the lessons. Scores reflect your answers in the app; they are not professional certification or a prediction of safety. You can also create an optional personal medical card. Enter details yourself or choose to import supported information from Apple Health, then review it before saving. If you choose to show or share a medical QR code, it contains your medical summary and emergency contact. Anyone with the code can read that information. KWTD is an educational tool. It does not dispatch emergency services, provide live emergency alerts, diagnose conditions or replace medical care. In an emergency, contact local emergency services and follow current instructions from local authorities and responders.

Verdict
The clearest difference is update cadence: KWTD at every 5 days against CardWord's every 8 months. CardWord's advantage is iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
