Everything you need to stay focused, right from Home.
Forest's core mechanic is a session. You plant a virtual tree, choose a duration, and Forest's Deep Focus mode blocks your selected apps for that window. Leave early or open a blocked app mid-session and the tree can wither, a gentle guilt mechanic layered on top of real blocking. It's a genuinely clever way to make focus visible, and Forest's Time Guard feature can extend blocking outside of active sessions too.
The difference is what happens by default, before you've done anything. Forest requires you to start something, plant a tree, pick a length, for blocking to kick in. Fella's routines can start sessions on schedule, so blocking doesn't depend on you remembering, with one 5-minute emergency unlock per session. There's no tree to plant.
Time Guard is Forest's answer to the session problem, and it's a real one. Instead of blocking only while a Deep Focus session is active, Time Guard lets you set blocked hours in advance, so distracting apps stay locked on a schedule even when you haven't planted a tree that day. It's free, and it closes a real gap in the core product.
The schedule is still something you build and maintain. Time Guard blocks exactly the hours you configured it to, no more. Change your routine, add a new distracting app, or just never get around to setting it up in the first place, and the coverage is only as good as the schedule behind it.
Fella's routines are schedules too, but every one follows the same fixed rule. There's no per-schedule strictness to tune, and every session gets the same single 5-minute unlock.
Forest's environmental angle is real, not just marketing. In-app coin purchases have funded the planting of millions of actual trees through a partnership with Trees for the Future, and that tangible payoff is part of why so many people stick with the app for years. It gives a session emotional weight a plain timer doesn't have. If price is part of the decision, continue with our other free app blockers for iPhone.
But emotional weight and a locked app are different things. Leaving the app mid-session, or ending it early, is still fully available to you the moment you decide guilt isn't going to win. The tree withers, and the distracting app opens anyway.
Fella has no guilt mechanic because it doesn't need one. There's nothing to feel bad about undoing, because there's no undo button in the first place. The block just holds, tree or no tree.

Routines can start sessions automatically. Forest's blocking is genuinely effective while a session is running, but it depends on you actively beginning one every time. Fella's routines start sessions on schedule, so you don't have to begin each one yourself.
A real limit, not a tree you can let die. Ending a Forest session early has a consequence, a withered tree, but it's still a choice available to you in the moment you're most likely to make it. Fella's one 5-minute unlock per session is the only exception, and it locks itself back up automatically.
Built for social apps specifically, not just deep-work blocks. Forest's roots are in focus timers for work and study sessions. Fella is built around the specific problem of distracting apps staying available all day, every day, whether you're "trying to focus" right now or not.
If you want a work or study session with a visible payoff, Forest's tree-growing mechanic and its real-world tree-planting partnership make focused time feel rewarding in a way Fella never tries to. A $3.99 one-time purchase is also hard to beat on price.
Fella is for the apps that don't wait for a session to start. If the problem is checking a distracting app between tasks, not during a planned focus block, a routine that starts blocking on its own matters more than a good session timer.
Forest is a $3.99 one-time purchase on iOS, cheaper upfront than Fella's $9.99 monthly or $34.99 annual subscription. Pricing can change, so check current listings before deciding on cost alone.
No. Fella has private streaks and achievements, but no visual focus-session reward system. It's a plain block list with one unlock per session, not a session you complete for a payoff.
Forest's Time Guard feature can extend blocking outside active sessions, but its core design is session-based. Fella is session-based too: you start sessions manually or let scheduled routines start them.
It's a visual and motivational one, not an access restriction, since leaving the app or ending a session early is still available to you in the moment. Fella's unlock per session has no equivalent soft option to weigh against a guilt mechanic.
Yes, Time Guard can block selected apps on a schedule you set, outside of active focus sessions. It's free and genuinely useful, but it still depends on you building and maintaining that schedule. Fella's routines are its schedule, and every session follows the same fixed rule.
Forest has funded the planting of millions of real trees through a partnership with Trees for the Future, based on in-app coin purchases. It's a genuine environmental angle layered on top of the core focus mechanic, and part of why the app has such a loyal following.
In pure dollar terms over a year or two, yes, Forest's one-time iOS purchase is well under a year of Fella. The tradeoff isn't price, it's that Forest's blocking still depends on a session or a schedule, while Fella's routines start sessions for you.
