If a fixed nighttime boundary fits your routine, you can download 9to9 from the App Store and choose the apps and websites you want quiet from 9 PM to 9 AM.
Let’s get the awkward part out of the way first: ScreenZen is free, extremely capable, and very popular.
As of September 2026, its U.S. App Store listing shows roughly 50,000 ratings with a 4.9-star average. It can add delays before opening apps, interrupt long sessions, set daily goals, limit the number of opens, create schedules, run strict blocks, protect settings, and more.
If you want a powerful free screen-time tool and you enjoy tuning rules until they fit your behavior, ScreenZen is difficult to argue against.
So why would anyone pay $19.99/year for 9to9?
Because sometimes the thing you are trying to buy is not more control.
It is fewer decisions.
9to9 does one job: the apps and websites you select are blocked from 9 PM to 9 AM every night. The schedule is fixed. There are no goals to tune, no varying limits, no app-by-app time budgets, and no daytime focus system.
ScreenZen is a toolbox.
9to9 is one rule.

What ScreenZen does well
ScreenZen’s strength is not one clever feature. It is the way it combines multiple behavior-change techniques.
Its current App Store description includes options to:
- add a delay before opening an app,
- increase that delay across repeated opens,
- limit how long each app session lasts,
- set daily screen-time goals,
- block once a limit is reached,
- configure different days and times,
- display prompts such as “Is this important?”,
- create strict blocking windows,
- lock settings,
- use breathing or other activities during the delay,
- track streaks.
That means you can build a system that is much more personalized than 9to9.
For example, you might allow Instagram for ten minutes at lunch, block TikTok until after work, permit Reddit three times per day, and completely lock social media after 11 PM.
9to9 cannot do that.
ScreenZen also says it is supported by donations rather than a subscription. Its site currently describes it as a free screen-time app available across iOS, macOS, Windows, and Android.
If free + flexible + cross-platform is exactly what you want, you may have already found your answer.
The hidden cost of a flexible system: you have to design it
The problem with customization is not that customization is bad.
It is that every setting creates a new question.
How long should Instagram be allowed?
Should weekends be different?
Should Reddit get three opens or five?
Is a 10-second delay enough, or should it be 30?
Should YouTube be limited by minutes, opens, or schedule?
Should tonight be an exception because you are tired?
For some people, those controls create exactly the structure they need.
For others, they create a permanent administrative job around their own attention.
You start by trying to use your phone less. Thirty minutes later, you are still on your phone adjusting the system for using your phone less.
That is the niche 9to9 is designed for.
“One rule, no configuration” is a different product
9to9’s schedule cannot be customized.
It is always:
9 PM → 9 AM
You choose which apps and websites belong behind that boundary. At 9 PM, they are blocked. At 9 AM, they return automatically.
Calls, texts, alarms, and anything you did not select keep working.
If something actually requires access during the block, Temporary Access gives you five minutes after a 60-second pause. Then the distraction is blocked again.
There is no daily screen-time budget to fail.
There is no “you have 6 minutes remaining” warning to bargain with.
There is no decision at 11:30 PM about whether tonight should count as a strict day.
The premise is closer to brushing your teeth than running a productivity sprint: the same thing happens at roughly the same part of every day because that is simply the rule.
If you like this philosophy, see app blocker vs. willpower at night.
Is it worth paying for 9to9 when ScreenZen is free?
For many people, no.
That is the honest answer.
If you install ScreenZen, configure a strict nighttime block, and then leave the settings alone, you may get exactly what you need for $0.
There is no moral advantage to paying for fewer features.
9to9 becomes interesting when you have already learned something specific about yourself:
more settings do not make you more consistent.
Maybe you keep changing the schedule.
Maybe you build elaborate app limits and then override them.
Maybe every “flexible” rule eventually becomes a negotiation.
Maybe you do not want to think about screen time during the day at all. You just want the distracting part of your phone to disappear every night and return in the morning.
In that case, paying for a narrower product can make sense for the same reason people buy a physical alarm clock even though their phone already contains an alarm: sometimes separation and simplicity are the feature.
ScreenZen’s flexibility is a real advantage
There are also situations where 9to9’s simplicity becomes a hard limitation.
ScreenZen is a better fit if:
- 9 PM is too early or too late for your life,
- you work rotating or night shifts,
- you want different weekend rules,
- you need daytime limits,
- you want to reduce opens rather than completely block an app,
- you use Android, Windows, or Mac as part of the same distraction loop,
- you want a free solution.
9to9 should not pretend to solve those cases.
Its schedule is fixed precisely because the product is trying to remove configuration. If you need configuration, use a configurable product.
What if I keep ignoring Screen Time limits?
This is a common reason people move from Apple’s built-in tools to third-party blockers.
A warning that says you have reached your limit is useful only if you respect the warning. If your muscle memory is already trained to press “Ignore Limit,” another limit may simply become another tap.
ScreenZen tries to address this in several ways: delays, strict blocks, open limits, and locks on settings.
9to9 addresses it by avoiding daily time quotas entirely. There is no allowance to exhaust. The selected apps are simply outside the nightly window.

Does ScreenZen work for bedtime?
Yes.
ScreenZen explicitly supports scheduled strict blocking and markets bedtime as one of its use cases. It is not merely an “are you sure?” friction app.
If you want a customizable bedtime block, ScreenZen can be the better tool.
The distinction is not ScreenZen is weak / 9to9 is strict.
The distinction is:
- ScreenZen lets you construct the rule.
- 9to9 gives you the rule.
Does 9to9 collect which apps I block?
According to the current 9to9 App Store privacy disclosure, the developer reports Data Not Collected.
9to9 uses Apple’s Screen Time technology. The app selections are represented by opaque tokens, so the app can enforce the rule without building a server-side profile of which specific apps or websites you chose.
No account is required.
Privacy disclosures are worth checking again when you install any app because they can change with future versions.
Why not just use Apple Screen Time?
You absolutely can.
On iOS 27, Apple’s Screen Time includes schedules, time allowances, categories, Always Allowed apps, and cross-device syncing across supported Apple devices. On earlier iOS versions, you may see the older Downtime/App Limits terminology.
Apple’s tools are powerful and free.
Third-party apps exist because the hard part is rarely whether the operating system can technically impose a limit. The hard part is choosing a system whose defaults match your behavior closely enough that you stop managing it.
ScreenZen gives you more behavioral tools than Apple’s basic setup.
9to9 gives you fewer choices than Apple.
Both can be useful reactions to the same problem.
A simple decision framework
Use ScreenZen if your thought is:
I want to design exactly how my phone should behave.
Use 9to9 if your thought is:
I am tired of designing how my phone should behave.
Use Apple Screen Time if your thought is:
I already have the controls I need. I just need to set them up properly.
None of those answers is embarrassing. Screen time is not a competition to see who can solve behavior with the fewest tools.
The bottom line
ScreenZen is a very strong free alternative to paid screen-time apps. Its 4.9-star App Store rating and large user base are not difficult to understand: it gives people a lot of control without requiring a subscription.
9to9 makes a narrower bet.
It asks you to give up flexibility in exchange for a rule you rarely have to think about:
9 PM: distracting apps go quiet.
9 AM: they come back.
Repeat.
If the fixed schedule matches your life, that simplicity may be worth more to you than another page of settings.
If it does not, ScreenZen is probably the more sensible tool.
You can try 9to9 free for 7 days. After the trial it is $19.99/year unless canceled before renewal.
What ScreenZen's flexibility actually buys you
“More settings” can sound like a criticism until you need one of those settings.
ScreenZen lets you shape restrictions around different apps, days, times, limits, opening delays, and stricter blocks. That is useful when your phone problem has several different forms.
For example, you might want:
- a pause before Instagram all day;
- a strict TikTok block during work hours;
- a pickup limit for Reddit;
- a different weekend rule;
- a blackout window before bed.
9to9 cannot reproduce that system. Every selected app follows the same 9 PM–9 AM boundary.
So if you enjoy experimenting and want a single toolkit for multiple screen-time problems, ScreenZen's configurability is not clutter—it is the point.
Where configuration can become its own form of procrastination
There is another kind of user, though: the person who has already spent a surprising amount of time designing the perfect system for using their phone less.
They adjust limits. They create Focus modes. They change schedules. They add exceptions. They remove exceptions. They install another blocker. They watch a video about the blocker.
The system becomes a hobby.
For that person, a feature-poor tool can be useful precisely because there is less to optimize.
9to9 makes one opinionated choice for you: nighttime means 9 PM–9 AM. You still choose what gets blocked, but there is very little else to tune.
That is not objectively better design. It is a different design strategy: reduce the number of decisions involved in maintaining the boundary.
Free vs paid: what are you actually paying for?
ScreenZen's no-subscription model is a serious advantage. If it solves your problem, there is no clever reason to avoid it simply because another app has nicer branding.
So what could justify paying $19.99/year for 9to9?
Not a longer feature list. ScreenZen wins that contest.
The case for paying is narrower: you specifically want the fixed automatic nighttime rule, you prefer the minimal experience, and you value having a product whose entire design is built around that one job.
A specialized product can be worth paying for even when a flexible free product can technically reproduce the same outcome. But that is a preference, not a mathematical truth.
Try ScreenZen if price is the main constraint. If you find yourself endlessly configuring or bypassing your setup and your real problem is simply nighttime, then try the more opinionated approach.
Frequently asked questions
Is ScreenZen really free?
ScreenZen's official site describes it as free and donation-supported, with no subscription required. The App Store may show in-app purchases because users can support the developer. Always check the current listing in your region.
Can ScreenZen schedule a nighttime block?
Yes. ScreenZen includes scheduling and stricter blocking options, so it can be configured for bedtime use. That is why this comparison is not “ScreenZen can't do nights.” The difference is that nighttime is one configuration among many in ScreenZen, while it is the entire product in 9to9.
Does 9to9 have daily time limits?
No. It is not a “30 minutes of Instagram per day” tool. Selected apps are available outside 9 PM–9 AM and blocked inside the window.
Can I use 9to9 during the day?
The nightly restriction itself only applies from 9 PM to 9 AM. If daytime impulse control is your main problem, ScreenZen, One Sec, or Apple's Screen Time controls are a better fit.
What happens if I need a blocked 9to9 app at night?
9to9 includes Temporary Access: request access, wait through a 60-second pause, and receive five minutes. It is designed as an escape hatch for a genuine need, not a one-tap “ignore limit” button.
Which one has more features?
ScreenZen, easily. That is not the same question as which one will fit you better.
Which one requires less setup?
9to9 is intentionally simpler because the schedule is fixed. ScreenZen gives you more control, which naturally means more choices.
A one-week test that is better than reading another comparison
If you are undecided, test the behavior rather than the marketing pages.
For seven nights, configure ScreenZen to protect the window you actually want. Do not keep changing it every day. Notice whether the system disappears into the background or whether you keep negotiating with it.
Then, if your desired boundary really is 9 PM–9 AM, try 9to9's free trial and notice the opposite tradeoff: fewer choices, but also less flexibility.
After that, the answer is usually obvious. Keep the tool you think about less.
Strictness is not one single setting
People often ask which blocker is “stricter,” but strictness has several parts.
There is access strictness: how hard is it to open the app right now?
There is configuration strictness: how easy is it to change the rule you created earlier?
And there is scope: does the rule cover one app, a category, a website, a time window, or the whole device?
ScreenZen gives you tools to make different rules more or less strict depending on the setup. 9to9 uses a stronger default concept during one narrow window and then offers Temporary Access after a 60-second pause for genuine needs.
Neither should be treated like enterprise device management. You own the iPhone, and Apple's system ultimately gives the device owner control. The useful question is whether the blocker adds enough friction to interrupt your normal bypass behavior.
If you are switching from ScreenZen to 9to9
Do not switch because you think paid automatically means stronger.
Switch only if you have identified that the configuration itself is the problem: you keep changing rules, creating exceptions, or spending time tuning a general-purpose tool when what you want is one nightly boundary.
Pick the handful of apps that cause the bedtime problem, try 9to9 for its 7-day trial, and leave the rest of your daytime ScreenZen setup alone if it is useful. You can even keep both temporarily while you compare the experience.
After a week, ask which app required less mental maintenance—not which settings screen looked more impressive.
What about privacy?
ScreenZen's privacy practices should be evaluated from its current App Store/Play Store disclosures and policy, because its multi-platform feature set can evolve.
9to9 is intentionally narrower. It does not require an account, and its current U.S. App Store privacy label says Data Not Collected. App selections are handled through Apple's Screen Time framework rather than presented to 9to9 as a normal readable list of app names.
As with pricing, verify current store disclosures if privacy is a deciding factor. A comparison article should not freeze a developer's privacy label in time.
The boring tool can be the better tool
There is a tendency in productivity software to equate capability with quality.
But if the goal is to use software less, a product can become better by asking you to configure less.
ScreenZen is impressive because it gives you control. 9to9 is intentionally boring because it removes control over the one dimension it cares about: the nightly schedule.
That is the whole comparison in one sentence.
Before you pay for the simpler option
Use ScreenZen's free tools seriously for a few nights first. If they work and you are happy with the setup, keep them. A paid alternative should earn its place by reducing maintenance or fitting your behavior better—not by convincing you that free software is somehow less legitimate.
If simplicity itself changes your behavior, then simplicity is a feature worth evaluating like any other.
