How to turn your iPhone into a dumb phone

Every few months the dumb phone comes back around. Someone buys a Light Phone II, writes about how quiet their week was, and a few thousand people open a browser tab to price one up. Then they hit the part where they would lose the camera, the maps, the banking app and the group chat that organises their life, and the tab gets closed.

The instinct is right. The purchase usually isn’t. What people actually want is not a worse device — it is a phone that stops asking for their attention when they didn’t ask for anything. That is a software problem, and it can be solved on the phone already in your pocket.

Here is the full conversion, in the order that matters.

Step 1 — Work out what you are actually trying to remove

Before changing a single setting, open Settings → Screen Time and look at last week honestly.

You are looking for two different problems, and they need different fixes:

• Volume. One or two apps that quietly eat two hours a day. These need a limit.
• Frequency. Forty, sixty, a hundred pickups where you opened the phone for nothing in particular. These need friction, not limits.

Most people arrive assuming they have a volume problem. Most people have a frequency problem. Americans check their phones on the order of dozens to nearly 200 times a day depending on whose survey you read, and almost none of those are decisions. Fixing the reflex matters more than shaving twenty minutes off an app.

Write down the three apps and roughly how long you would like to spend in each. That list is the whole configuration.

Step 2 — Kill the colour

This is the cheapest change with the largest first-week effect, and it is the one dumb-phone converts describe most often without realising it is what they are describing. App icons are designed to be found by peripheral vision. Grayscale takes that away.

On iOS: Settings → Accessibility → Display & Text Size → Color Filters → on, Grayscale. Then Settings → Accessibility → Accessibility Shortcut → Color Filters, so a triple-click of the side button toggles it. You want the escape hatch — you will need colour for photo editing, for maps in bad light, and for looking at anything anyone sends you.

Does it work? Reasonably well, and the research is real rather than folklore. A 2023 intervention study by Dekker and Baumgartner found a week of grayscale cut daily screen time by around 20 minutes and significantly reduced participants’ sense of being overwhelmed by their phones — but it did not change how often they unlocked the device (Dekker & Baumgartner, Mobile Media & Communication, 2023). Earlier work by Holte and Ferraro found a larger reduction — around 38 minutes — in a college sample.

That split is the important part. Grayscale shortens sessions. It does not stop you starting them. Which is why it is step two of six and not the whole article.

Step 3 — Replace the home screen with words

A grid of icons is a menu. A menu invites browsing. This is the core of what a dumb phone gets right: there is nothing to look at, so there is nothing to look at.

You have three options on iOS, in increasing order of effect:

The manual version. Move every app off the first home screen into the App Library, leave the first page empty except for the four apps you genuinely open on purpose, and turn off all badges you do not need (Settings → Notifications, app by app). Free, takes twenty minutes, and it decays — new apps reappear, and you will drift back.

The Shortcuts version. Build a text-only launcher out of Shortcuts widgets. It looks the part but it is fiddly, the widgets are slow, and maintaining it is a hobby.

A launcher app. Halt replaces the home screen with a monochrome, text-only list: app names as plain type on black, nothing else. It is the version that survives contact with a normal week, because there is no configuration to drift.

Whichever you pick, the rule is the same: anything not on the list should cost a search. Not a lot — just enough that opening it is a decision.

Step 4 — Put real limits on the two or three apps that take the day

iOS ships with App Limits, and they are better than people give them credit for. Settings → Screen Time → App Limits. Set a daily budget per app or per category.

Their weakness is well known: the “Ignore Limit” button is one tap away, and after two weeks your thumb finds it before your brain does. Two things help.

• Set the limit slightly generously the first week. A limit you blow through on day one gets disabled by day three. A limit you hit at 8pm gets respected.
• Use a blocker that costs more than one tap to override. Third-party apps built on Apple’s Screen Time API can add a real pause, a typed confirmation, or a delay, and cannot be dismissed by reflex alone.

Anything built on the Screen Time API — Halt included — is doing enforcement through Apple’s own system, which is why it works at the OS level rather than as a suggestion inside an app.

Step 5 — Add friction to the reach itself

This is the step that separates a phone that is quieter from a phone that is genuinely different, and it is the step the dumb phone gives you by accident: on a Nokia, the feed is not there, so reaching for it fails.

On an iPhone you reproduce that with delay. Instead of blocking an app outright, you make opening it take a few seconds of deliberate attention — a mandatory pause, a breath, a prompt asking what you came for.

The evidence here is strong. A PNAS paper on the self-nudge app one sec, which inserts a short breathing pause before a target app opens, reported a 57% reduction in use of the apps people applied it to, with the effect still present six weeks later (Grüning, Riedel & Lorenz-Spreen, PNAS, 2023). Not a block. A wait.

The reason it works is that most app opens are not decisions. They are a completed motor sequence — pocket, thumb, unlock, fourth icon — that runs before any conscious intention arrives. Interrupt the sequence and there is frequently nothing behind it. You put the phone down not because you were denied, but because you noticed there was nothing you actually wanted.

This is what Halt’s friction prompts and doomscroll interrupter are for: the pause between the reach and the feed, and a second one for when you have already been scrolling for twenty minutes without choosing to.

Step 6 — Keep a real dumb phone mode for when you want it

The last piece is the one that makes the whole thing safe to commit to: a switch that reduces the phone to calls, messages and navigation for a set period, and then gives it back.

iOS Focus modes get you partway — a custom Focus with an allowed-apps list is genuinely good and costs nothing. A dedicated mode (Halt calls it Deep Freeze) goes further by locking the exit as well, so a dinner, an evening or a whole weekend is decided once rather than defended forty times.

The reason to have this rather than to simply own a dumb phone: you can end it. You keep the camera at your kid’s birthday, the maps in a strange city, the banking app when the card is declined. A Light Phone makes that decision permanently, in advance, for every situation. A mode makes it for the next three hours.

What you end up with

Run all six and the device in your pocket behaves like this: a black screen with a clock and seven words on it, no colour, no badges, three apps that stop at a budget you set, a few seconds of resistance in front of anything designed to be sticky, and a switch that turns the whole thing into a phone-shaped phone whenever you want.

That is a minimalist phone. It costs nothing, it keeps your number, and it is reversible on a bad day, which is exactly what makes it survive past week two.

The honest caveats

• Any of this can be defeated. You can turn off the blocker, delete the app, disable the filter. Any product that tells you otherwise is selling certainty it cannot deliver. The point is not to make it impossible, it is to make it deliberate — and deliberate is enough for most of what screen time is made of.
• The first week is not the test. Novelty does a lot of work in week one. Judge it in week three.
• Blocking is not free of cost. A 2025 study that cut mobile internet entirely for two weeks found large improvements in sustained attention, mental health and well-being — with 90.7% of participants improving on at least one measure (Castelo et al., PNAS Nexus, 2025) — but participants also had to give things up. Removing distraction removes some convenience with it. Decide what you are willing to lose before you start, not at 11pm on day four.
