But he also created wuphf so he did one thing right. (But not really because it would be better if this app actually worked) maybe Kelly distracted him from finishing the app before putting it out on the App Store 🙃 ### 2/5 — Idee *2019-03-04, version 2.0.3* Leider unter iOS 10.3.3. (Original) Vollabsturz, direkt nach App-Start. Die 2. Sterne sind für die Idee. (Für die Entwickler von JSON Designer ist das allerdings ein mageres Ergebnis) ## Frequently asked questions about WUPHF ### What does WUPHF do?
