LatchTurn your iPhone or Android into a dumb phone, without buying a second phone
A dumb phone app locks the parts of your smartphone that eat your time, like social feeds, video apps, the browser and games, and leaves the parts you need: calls, texts, maps, the camera, music and your bank's two-factor codes. Latch does this on iPhone, iPad and Android, and it only unlocks when you scan a key you keep somewhere else. If you'd rather not own a smartphone at all, a real dumbphone such as the Light Phone is the cleaner choice. Both are covered below.
We make Latch, so read this with that in mind. Dumbphone prices and features come from the makers' own websites and support pages, checked October 2026, and link to their sources.
A dumb phone app vs a dumbphone
| Feature | Your phone with Latch | A dumbphone (Light Phone III) |
|---|---|---|
| Cost | Free; Latch Pro is $9.99 once. Your phone and plan stay the same | $899, listed as a pre-order (Light), plus a SIM on a supported carrier |
| Feeds, browser, games | Locked until you scan your key, on a schedule, or at places you choose | Not there at all: "no infinite feeds, no social media, news, advertising or email ever" (Light) |
| Maps, camera, music | The apps you already use | Directions, a camera, music and podcasts are built in (Light) |
| WhatsApp, iMessage, banking apps | Keep them unlocked if you need them | No WhatsApp; you turn off iMessage before you switch (Light) |
| Getting back in | Walk to your key; Break glass 3 times a month for emergencies | Pick up your old smartphone, if you kept it |

How to turn your smartphone into a dumb phone
1. Decide what a dumb phone means for you
Write down what you need the phone for. For most people that's calls, texts, maps, the camera, music or podcasts, and one or two apps for work, banking or two-factor codes. Everything else is a candidate for the lock: social media, video, news, shopping, games and the browser.
2. Lock the rest with a key you have to walk to
In Latch, make a profile and choose the apps, categories and websites to block. Then add a key: an NFC sticker, a printed QR code, or, with Latch Pro, a number of steps. Put the sticker somewhere inconvenient, like the fridge or a drawer downstairs. While the profile is locked, your phone works like a simple one, and the only everyday way back to the feeds is to go and scan the key.
3. Stop the obvious way around it
A dumb phone that you can turn back into a smart one by deleting and reinstalling an app doesn't last long. Latch's Hard lock can stop deleting apps, installing apps and in-app purchases while you're locked on iPhone. On Android it blocks installing apps and the Play Store, so a deleted app can't come back until you unlock.
4. Let it lock on its own
With Latch Pro, a schedule can make your phone dumb at set times, such as evenings and weekends, or only while you're at a place. Latch can also lock when you arrive somewhere, while you're driving, or when you ask Siri ("Latch my phone") or Google Assistant. Commitment mode keeps a profile locked for a set time, from 30 minutes to 8 hours, and not even your key opens it early.
5. Make the screen boring
Grayscale takes the shine off. On iPhone it's in Settings › Accessibility › Display & Text Size › Color Filters (Apple). On Android, Digital Wellbeing's Bedtime mode has a grayscale option that "changes your screen to black and white" (Google). Moving the remaining apps off your first home screen helps too.
What about Assistive Access on iPhone?
Apple's Assistive Access is a simplified iPhone layout with large buttons and a few apps. Apple describes it as an experience "which allows people with cognitive disabilities to use iPhone with greater ease and independence" (Apple). It's built for that purpose, with a separate setup, so it's a heavy way to cut down on scrolling. For most adults, locking a handful of apps does the job with less fuss.
When a real dumbphone is the better choice
An app blocker is a fence around apps that are still on your phone. Some people do better with no apps there at all. A dumbphone is worth it if:
- you keep finding ways around software limits, and want the decision made once
- you want a phone a child can carry without a smartphone
- you can live without WhatsApp, a web browser and most banking apps, or can keep them on a tablet at home
The best-known option in the US is the Light Phone. The Light Phone III is $899 and was listed as a pre-order with delivery in late December when we checked (Light). It has calls, texts, a camera, directions, music, podcasts, a hotspot and a few other tools, and "the Light Phones do not have an internet browser or social media" (Light). It needs an active SIM: Light sells its own plan, and the phone also works with carriers including AT&T, T-Mobile and Verizon (Light). The new Light Phone II was sold out, with refurbished units at $175, and Light also sells the Light Flip at $349 (Light).
The Mudita Kompakt is a $399 phone with an E Ink screen, a camera and offline maps, and it "does not include an app store" (Mudita, store).
The cost of a dumbphone is the phone, and also everything you'd move off it: group chats on WhatsApp, iMessage, ride-share and parking apps, and two-factor codes. Some people carry both and leave the smartphone at home. If that's you, Latch can still help on the smartphone.
Why try the app first
It costs nothing to try, and you keep the phone number, group chats and apps you can't drop. If a month of locked feeds is enough, you've saved the price of a second phone. If you find yourself breaking the rules every day, that's a good sign a dumbphone is worth the money.
Which should you choose?
Buy a dumbphone if
- you want no feeds on the device at all
- you don't rely on WhatsApp or banking apps
- you're happy to pay for a second phone
Use Latch if
- you need maps, the camera or a few work apps
- you want the dumb phone only at certain times
- you'd rather pay $9.99 once, or nothing
- you use Android, iPhone or both
Common questions
What is a dumb phone app?
An app that makes a smartphone work more like a basic phone by locking social media, video, games and the browser while leaving calls, texts, maps and the camera. Latch does this on iPhone, iPad and Android, and only unlocks when you scan a key you keep somewhere else, such as an NFC sticker on the fridge.
Can I turn my iPhone into a dumb phone?
Yes. Block the apps, categories and websites you don't want with an app blocker like Latch, keep Phone, Messages, Maps and the camera, and turn on grayscale in Settings › Accessibility › Display & Text Size › Color Filters. Hard lock can stop you deleting and reinstalling apps while you're locked.
Can I turn my Android phone into a dumb phone?
Yes. Latch works on Android 9 and later. Choose the apps and websites to lock, and Hard lock can block installing apps and the Play Store while you're locked. Digital Wellbeing's Bedtime mode can also switch the screen to grayscale.
Is a dumbphone better than an app blocker?
It's stricter, because the apps aren't there at all. It also costs more: the Light Phone III was $899 when we checked in October 2026, and you lose apps like WhatsApp. An app blocker is cheaper and keeps the apps you need, but you can still find ways around it, such as Latch's Break glass, three times a month.
Does the Light Phone have WhatsApp?
No. Light's support pages say WhatsApp isn't supported and give no timeline for it. The Light Phones also have no internet browser or social media.
Is Latch a dumb phone app?
Latch is an app blocker you can use that way. It locks the apps and websites you choose until you scan your key, and it can lock on a schedule, at a place or while you're driving. It's free with one key; Latch Pro is $9.99 once.
Make the phone you have a little dumber
Latch is out now on the App Store for iPhone and iPad, and on Google Play (Android 9 and later). It's free to start, and Latch Pro is $9.99 once.
