"Best" depends on what's actually not working. Awareness, friction, gamified focus, and hard blocking solve four different problems, and most people only need one of them.
Trusted by 500+ people
Screen time apps split into four real approaches, not one category. Trackers show you the problem. Friction apps add a pause before you act on it. Gamified timers reward you for staying away during a session. Hard blockers remove access outright. Each one fixes a different failure point.
Picking the wrong type is the most common reason "it didn't work." A tracker can't stop a habit it only measures. A gamified timer built for deliberate focus sessions isn't built to keep an app blocked all day. Match the tool to the actual problem first.
| Best for | App | Why |
|---|---|---|
| Strict default-blocked apps | Fella | Blocked by default, one 5-minute emergency unlock per session, nothing to configure. |
| Mindful friction before opening | One Sec | A short breathing pause before a chosen app opens, not a hard block. |
| Fully free friction option | ScreenZen | No premium tier at all; every feature is free. |
| Scheduled focus sessions | Opal | Aggressive, hard-to-bypass sessions, iOS-only. |
| Blocking across phone and computer | Freedom | One blocklist enforced on every connected device at once. |
| Gamified focus timer | Forest | Grow a tree during a session; leave the app and it dies. |
| Usage awareness and analytics | RescueTime | Detailed reports on where time actually goes, aimed at knowledge work. |
| Free built-in starting point | Apple Screen Time | Already on your phone, but the weakest option for enforcement. |
Fella (iOS, $9.99/month or $34.99/year, no free trial on either plan). Choose the apps that distract you, start a blocking session manually or through a scheduled routine, and get exactly one 5-minute emergency unlock per session that locks itself again automatically. There is no detailed tracking dashboard. If the built-in controls are not enough, compare our free iPhone app blocker options.
One Sec (iOS, free for one app, $4.99/month or $39.99/year for more). Instead of blocking outright, One Sec inserts a short breathing pause and a "do you still want to open this?" prompt before a chosen app opens. Research with the Max Planck Institute found it cut app opens by roughly half for people who used it consistently, but it's friction, not a hard stop.
ScreenZen (iOS/Android, free). A friction-based blocker similar in spirit to One Sec, with more customization and no premium tier at all. Good starting point if you want to try the approach at zero cost before paying for anything.
Opal (iOS, roughly $19.99/month or $99.99/year). Built around scheduled Focus Sessions that block chosen apps hard for a set window. The free tier is limited to a few sessions, and the price is the highest on this list, but the sessions themselves are genuinely difficult to bypass mid-session.
Freedom (iOS, Android, Mac, Windows; roughly $8.99/month, $39.99/year, or a $129.50 lifetime option). The main advantage is reach: one blocklist and schedule enforced across your phone and computer at the same time, which matters if your distraction isn't limited to your iPhone.
AppBlock (iOS/Android, roughly $4.99/month, $29.99/year, or $89.99 lifetime). A more budget-friendly blocker with a Strict Mode and an Approval Access feature that requires a trusted contact's permission to unlock, which is closer to an accountability-partner model than a solo one.
Forest (iOS one-time purchase around $3.99, Android free with ads). A gamified focus timer: start a session, a tree grows, and leaving the app kills it. It's built for deliberate, timed focus blocks rather than an always-on block on specific apps throughout the day.
RescueTime (free tier, paid plans for deeper reporting). Primarily a tracker aimed at knowledge workers, with detailed breakdowns of focus time versus distraction time across apps and sites. It's built to inform, not to block anything by default.
Apple Screen Time (free, built in). Useful for baseline awareness through its weekly reports, and it's the only option here that costs nothing extra. As an enforcement tool it's the weakest on this list, mainly because of the Ignore Limit override covered on our Screen Time troubleshooting page.
If you don't know where your time goes yet, start with a tracker like RescueTime or Apple's own Screen Time reports before adding any blocking layer.
If you know the problem but a hard "no" feels too extreme, a friction app like One Sec or ScreenZen adds a pause without removing access entirely.
If you need deliberate, timed focus blocks for work, a gamified timer like Forest or Opal's Focus Sessions fits a scheduled work session better than an all-day rule.
If you've already tried the softer options and keep finding the override, a default-blocked tool like Fella, Freedom, or Opal removes the daily decision entirely.
Apple's built-in Screen Time is free and a reasonable starting point for awareness, and ScreenZen is a fully free third-party option that adds friction before opening chosen apps. Neither enforces a hard block by default the way a dedicated blocker does.
A tracker like RescueTime or Apple's own Screen Time reports show you how much time you spend and where, without necessarily stopping you from continuing. A blocker like Fella, Opal, or Freedom actively prevents access to chosen apps once a rule is active.
Opal is iOS-focused with strong, scheduled focus sessions but a limited free tier and a higher monthly price. Freedom works across phone and computer at once, which matters if your distraction happens on multiple devices, not just your iPhone.
For people motivated by a visual reward, yes, growing a tree gives a concrete reason not to leave the app. It works better as a focus-session timer for deliberate work blocks than as an always-on blocker for apps you want restricted all day.
If Screen Time's Ignore Limit button has become part of your routine, a blocker with no equivalent override, like Fella, Opal, or Freedom's Locked Mode, addresses that specific gap better than another awareness or tracking app.
ScreenZen is fully free and uses a friction-based approach rather than a hard block. AppBlock and Refocus both offer usable free tiers with paid upgrades for stricter modes.
Fella skips focus sessions, schedules, and tracking dashboards in favor of one rule: chosen apps stay blocked by default, with one 5-minute emergency unlock per session that locks itself again automatically.
If you're not sure which apps are actually the problem, yes. A week of tracking data makes it obvious which one or two apps deserve a hard block, rather than guessing and blocking apps that were never really the issue.
Yes, they solve different problems and don't conflict. Some people keep a tracker like RescueTime running for visibility while using a hard blocker like Fella for the specific apps they've already identified as the issue.
