If you upgrade to the Pro version for a fairly reasonable price ($ 2.60 for E.U. residents and $ 2.99 for U.S. residents), you will have access to themes, setting
custom vibration levels, more hardware button support (provided your phone has those buttons), and blacklist remapping buttons while within certain applications.
There's even a bonus if you use AutoNotification to control notifications for apps that already implement notification channels:
setting custom vibration patterns works for those apps as well!
It features the tapping of the glass feature to recall alerts, like the current Guess Connect does, and it also has
the custom vibration function of the original device too.
But there are plenty of other tweaks too, from a range of gesture controls to
custom vibration settings for incoming calls.
Just pick
a custom vibration alert for that contact by selecting Edit in the top right corner, then tapping the Vibration option under Ringtone or Text Tone.
The companion app allows you to easily pick which apps you want to serve up notifications with the option to set
a custom vibration pattern for each one.
