Hey there onlybecc4,
Thanks for reaching out to the Apple Support Communities.
To get started, have you also attempted to remove the app by going into Settings > General > iPhone Storage? From there just locate and tap the app, then tap "Delete App".
If not, are you able to redownload the app, or do you see an error or message saying the app is still downloaded when trying to download the app from the App Store?
If able to, try redownloading and deleting the app once again using the steps outlined here: Delete apps on your iPhone, iPad, and iPod touch - Apple Support
How to delete an app
1. Touch and hold the app.
2. Tap Remove App 
.
3. Tap Delete App, then tap Delete to confirm.
Keep in mind that some built-in Apple apps can't be deleted from your device, so you might not see the option to delete an app. Here’s a list of built-in Apple apps you can delete from your device. If you can't delete an app that's not made by Apple, disable parental controls, then try deleting the app again.
If you touch and hold an app from the Home Screen and the apps start to jiggle:
1. Tap the Remove icon 
in the upper-left corner of the app.
2. Tap Delete App, then tap Delete to confirm.
3. Tap Done.
Trying these steps can help with resolving the issue that you've been experiencing.
If still seeing the same issue after redownloading and deleting the app, or if you're unable to redownload the app, then we'd recommend reaching out to Apple Support for additional help at this link here: Apple Support
Take care.
