Our verdict: Forth is the better pick if you want blocking included and an approach that works for anyone, religious or not. Forth blocks the apps and sites you choose as part of its one plan. Unchaind needs its Max plan for that. On top, Forth gives you a short visual game for the moment an urge hits, and no account. Unchaind suits you better if you want prayer and scripture at the center.
We make Forth, so we’re biased, but every fact about Unchaind 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 If something is out of date, tell us and we’ll fix it.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
Blocking included, no upgrade tier
Forth’s blocker comes with the subscription. Unchaind’s App Store listing says blocking chosen apps and sites requires Unchaind Max.
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.
No account, and your data stays on your phone
You don’t sign up for anything. Your plan, reflections, progress and blocker choices stay on your iPhone.
A slip doesn’t wipe you out
Finished Resets grow a world you keep, and a setback doesn’t take any of it away. Streak counters, by design, start over at zero.
