I would definitely get a fret rocker. This one is inexpensive and actually straight. Many of the lower priced ones are not flat and that really defeats the purpose. This one is: https://elmerguitar.com/products/fret-rocker

Peterson makes strobe app you can use on an iPhone on Anddroid. $10 in your favorite app store. https://www.petersontuners.com/products/istrobosoft/

....don't forget intonation (open string is tuned on pitch same open and at 12th fret.

Easy to do moving the saddles back/forward......simple rule of thumb:
FLAT - FORWARD
SHARP - BACK
