No idea bro. Install and try them out. I don’t remember Niagara from when I trialled it.

Use this table and try a few. Find one you like. You can check the privacy report for trackers etc on the Exodus site.

I tried a whole bunch of launchers and settled on Pear launcher. I keep KISS launcher solely for the search (launch KISS search on double tapping the home button). Neo launcher was on its way to greatness, but then development was abandoned… So if anyone has the skills/time/interest in forking that, that would be great.
