Our verdict: Forth is the better pick if you want to quit privately, on your own schedule, for about a quarter of the price. Forth is $39.99 a year in the US. Relay is $149. Forth gives you a short visual game for the moment an urge hits, a plan, and built-in Screen Time blocking, with no group to report to. Relay suits you better if a small accountability group is what you need.
We make Forth, so we’re biased, but every fact about Relay here comes from its own App Store listing and website. If something is out of date, tell us and we’ll fix it.
Why Forth comes out ahead
About a quarter of the price
Forth is $39.99 a year in the US. Relay is $149 a year, according to its website (as of October 2026).
It helps in the moment, not just after
When an urge hits, Forth gives you something to do right then: a short visual game where you fit shapes, match patterns or rebuild a painting. The idea comes from craving research: in a 2015 study, three minutes of Tetris made cravings about 14 points weaker on a 0–100 scale, including cravings for sex.
