If you're a Twitter addict, you might like this one. On newer iPhones, i.e. the iPhone 6s and up, the Taptic Engine gives feedback when adjusting things such as the time on an alarm, or using 3D Touch, it's almost everywhere, but not on most Twitter functions. You can now add more feedback within the Twitter app with HapticTwitter.
This tweak once installed, simply adds feedback when doing such things as sharing, liking, or retweeting. There's nothing to configure in the Settings.app, so all you have to do is install it, and you're good to go. It's available on BigBoss for free, so you don't have to pay or add any sources to your device.
It's listed as iOS 10 compatible, but may work with iOS 9, the API called should allow for iOS 9 support. It's also unclear whether instead of using the Taptic Engine if it will use the vibration motor on older devices. Let us know if it works on older iPhones and older iOS versions in the comments.
The developer has also said on the Reddit announcement post that they will open source the code of the tweak so that other community developers can add haptic feedback to other popular apps.
