Hi ctinc,
If you like solving sudoku puzzles almost like in a paper using pencil (no filter, no built in hints or solver),
I suggest the "Quarzo sudoku" app. Sure, it allows pencilmarks and if you want you can
have them filled in the grid (useful if you want to tackle higher levels instead of the
daily puzzles). The app allows coloring for digits
(here my request was kindly granted. This is very useful if you want to face levels like nightmare, grandmaster).
The quality of the puzzles is excellent
[daily, easy,intermediate,hard, expert, extreme,nightmare,grandmaster].
In the daily the levels alternate: easy, intermediate and hard.
Of course, no advanced technique is needed for the daily.
For me, just the daily is enough to exercise the basics (I did not miss a single one since 2020)
and once a week I solve some nightmare.
So, an app with these characteristics is "best" in my POV. If you prefer more features, I suggest the
"enjoy sudoku" app, if still available.
Regards,
JCO
