DMOnly vs ScreenZen: Paid Block vs Free Friction
ScreenZen is the unusual app blocker that's actually free — not "free trial," not "free with a paywall everywhere," but free indefinitely. DMOnly costs $40/year and enforces a hard daily cap. Both are honest products solving the same problem differently. This is when free is enough, and when it isn't.
TL;DR
- ScreenZen adds friction delays (5-10 seconds) and intention prompts before you open distracting apps. Genuinely free core product, ~$5/mo Premium for advanced features.
- DMOnly locks apps by default and enforces a hard daily quota — no override, no extension. $4.99/mo or $39.99/yr.
- Pick ScreenZen if you want to try a blocker before paying for one, or if friction-based interventions work for you.
- Pick DMOnly if you've tried ScreenZen (or any pause-based blocker) and learned to tap through the friction without thinking.
The core difference: friction vs. constraint
ScreenZen's mechanism is friction. You tap Instagram, ScreenZen interrupts you with a delay timer or a "why do you want to use this?" prompt. After the friction, you can continue. The friction itself is the intervention — it slows your impulse just enough that some percentage of the time, you choose differently.
DMOnly's mechanism is constraint. You tap Instagram, it's locked. No friction screen, no delay, no question to answer. The app simply isn't available unless you've opened a 15-minute window from DMOnly's home screen, and you only get 2-10 of those per day. Once spent, that's it.
ScreenZen asks: "Do you really want to open this?"
DMOnly answers: "You can't right now. You used your windows."
These describe two different theories of habit change. ScreenZen bets that gentle, sustainable friction is enough for most users. DMOnly bets that the people who installed an app blocker have already lost the "gentle friction" fight and need something stricter.
Side-by-side at a glance
| DMOnly | ScreenZen | |
|---|---|---|
| Core mechanic | Lock by default, daily quota | Friction delays + intention prompts |
| Does it actually block? | Yes (after quota) | No — friction only, always continueable |
| Free tier | 2 windows/day, full lock | Full core product |
| Paid tier | $4.99/mo, $39.99/yr | ~$5/mo for advanced delays |
| Platforms | iPhone | iPhone, Android |
| UI polish | Minimal, focused | Functional, less polished |
| Team / longevity | Solo founder, new (2026) | Small team, established |
| Free tier limit | Quota counts (2/day) | None practical — full app free |
How ScreenZen actually feels
You tap Instagram, ScreenZen interrupts with a configurable delay (5 to 30 seconds, your choice). You can set an intention prompt — a question like "What do you want to accomplish?" — that you answer before continuing. After the friction, Instagram opens normally.
What's clever: ScreenZen's settings let you tune the friction yourself. Want a gentle 5-second delay? Done. Want a 30-second wait plus 3 intention questions? Also done. The tradeoff: you can also turn it down whenever you want. The same flexibility that lets you set it strict lets you weaken it on a bad day.
The free tier is unusually generous — you can use the core product indefinitely without paying. Premium ($~5/month) unlocks more advanced friction options and removes any small limits. For many users, free is sufficient forever.
How DMOnly actually feels
No friction screen, no question to answer. You tap Instagram and either it opens (because a window is active) or you see iOS's standard "Restricted" screen with no override button. To get a window, you open DMOnly and see your daily quota — "8 windows remaining today" — and tap "Open a 15-min window."
The decision moment moves from "should I continue past this prompt?" to "should I spend a window?" — and once spent, that window is gone for the day, no take-backs. The asymmetry is intentional: it makes the decision harder to make on autopilot.
Pricing comparison
This is the clearest contrast in the category.
- ScreenZen: Free indefinitely. Premium ~$5/month (~$60/year if billed monthly).
- DMOnly: $4.99/month or $39.99/year (~$3.30/month if annual).
For the cost-conscious user, ScreenZen's free tier is a real "try before you buy" path that doesn't exist for most paid blockers. If the friction mechanism works for you, you may never need to pay anything.
DMOnly's pricing is in line with paid alternatives ($4-9/month is the category range), and is among the cheapest paid options if billed annually. You're paying for the mechanic, not the platform — DMOnly is iPhone-only with no cross-device sync.
Where ScreenZen is the right answer
- You've never used an app blocker before. ScreenZen is genuinely free, no pressure. Try the friction-based approach first; if it works, you're set.
- You're in the "reflexive open" failure mode. If your problem is grabbing your phone without deciding to, the pause/friction can interrupt the autopilot.
- You want Android too. ScreenZen works on both iOS and Android; DMOnly is iPhone-only.
- Money is the constraint. The honest answer for users who genuinely can't or won't pay anything: ScreenZen is the best free credible option in this category.
Where DMOnly is the right answer
- You've tried ScreenZen (or any friction-based blocker) and tapped through it on autopilot. Once your brain learns the friction means "wait then continue," the intervention loses power. DMOnly removes the "continue" step.
- Your problem is duration, not opening. Friction at the door doesn't help if you spend an hour inside. DMOnly's daily quota caps total time, not number of opens.
- You want a fixed daily limit, not flexible friction. Some people prefer "I get 10 windows, period" over "I tune my own friction levels."
- You're willing to pay $40/year for a stricter mechanism. The price difference is small in absolute terms; the mechanic difference is meaningful.
The honest answer about "free vs paid"
For app blockers specifically, "is free enough?" comes down to: how disciplined are you with self-imposed rules?
If you can stick to friction-based interventions because you respect your own commitments — ScreenZen is fine, and you should keep your $40 in your pocket.
If you've already learned that you'll bypass any rule you set for yourself the moment it becomes inconvenient — paying for a tool that takes the decision out of your hands isn't a luxury, it's a workaround for a known weakness. $40/year is cheap insurance against another year of distraction.
There's no universal right answer. The honest test: try ScreenZen for two weeks. If after two weeks you're either (a) using it successfully or (b) not using it at all (which tells you blockers aren't your bottleneck) — done, free is enough. If after two weeks you're using it daily but bypassing it daily — DMOnly is the next thing to try.

2 free windows per day — no card required. Try ScreenZen first if you've never used a blocker.

Is ScreenZen really free with no catch?
Yes — the core product is genuinely free. There's a paid Premium tier (~$5/month) that adds advanced features, but most users won't need it. This is rare in the app-blocker category, where most "free" apps are heavily limited demos.
Can I use both ScreenZen and DMOnly?
Technically yes, but it'd be confusing — both will interact with Apple Screen Time differently. Pick one tool and commit for at least 7 days before switching. Layering blockers tends to make compliance worse, not better.
Which has better customer support?
Both are small teams. ScreenZen has been around longer with a more established community. DMOnly is solo-built and newer — direct email support from the founder.
Will ScreenZen still be around in 5 years?
No way to know. ScreenZen has been operating for several years and seems stable; DMOnly is much newer. If long-term continuity matters to you, ScreenZen has a slightly better track record. If you'd switch in 5 years anyway, this doesn't matter.
