I find myself (especially with writing on the web) needing to convert text to match style cases frequently. I often need to change title case to just capitalized or vice versa. Without a little automation, it can be tedious.
- Title Case
- URL Encoded
You can then copy the option you need to use elsewhere. It also includes a share sheet extension so you can convert text from other apps.
Text Case is $1 on the App Store.
