## FAQ

**Q: How do I see which model an app was built from?**

In your Use Case, go to the [Applications](https://docs.datarobot.com/en/docs/wb-apps/index.html#applications-tab) tab. The Source column lists the model each app was created from.

**Q: Is there a way to see how many predictions were made using an app?**

You can view every prediction made in an app in the All Rows widget or by downloading them as a CSV.

**Q: Can I re-run an optimization in the Optimizer app after changing the widget's settings?**

At this time, you cannot re-run an optimization unless you recreate the prediction row.
