Notch is the first nicotine tracker built around milligrams, not pouch counts — because a 3 mg and a 9 mg pouch aren't the same hit. Set your own taper curve (no cold-turkey demands), watch your line bend down as you cut back, and quit alongside friends on a leaderboard. Days are Logged, Clean, or Untracked — never silent zeros — so your stats reflect reality. Privacy-first: no ads, no analytics, no data sold. Built by someone trying to quit. Free on the App Store.
