How can I lock apps on my iPhone?

I want to protect my privacy by locking certain apps on my iPhone, but I am unsure how to do this. Can someone guide me on the steps to lock apps effectively? It’s important to secure sensitive information.

Oh, locking apps on an iPhone, huh? Big privacy energy, I respect it. Apple’s a little weird about this—like, they don’t give you a straight-up ‘lock this app’ feature (because why make it easy, right?). But you can kinda make it work with Screen Time. Let me break it down for you:

  1. Screen Time:

    • Go to Settings > Screen Time > App Limits.
    • Turn on Screen Time if it’s not already (set a passcode too, obvi).
    • Tap Add Limit, select the category (or specific app), set the time limit to 1 minute… and boom, after you hit that limit, the app locks. You’ll need the Screen Time passcode to access it again. (Pro tip: don’t forget your passcode like… some people I know).
  2. Guided Access (for individual apps):

    • Open the app you want to lock down.
    • Triple-click the side or home button (depending what your phone has).
    • Choose Guided Access and set barriers so people can’t mess with the app. Don’t forget to actually set a passcode in Settings > Accessibility > Guided Access!
  3. Third-Party Apps: Yeah, Apple doesn’t officially let apps lock other apps (shocker), but there are paid apps out there that can add layers of restriction… maybe worth Googling if you’re really in a bind.

Bottom line: Apple makes you work for it, but it’s do-able-ish. No Face ID or Touch ID to lock individual apps though—not unless Tim Cook graces us with that feature someday. Classic Apple.

Screen Time and Guided Access are pretty solid options like @mike34 said, but let’s be real—that workaround with Screen Time feels clunky, right? I mean, using app limits to “lock” something? Eh, it’s more like a speed bump than a real lock. If you’re looking for something more seamless, Apple doesn’t give you much to work with natively (classic Apple gatekeeping).

But here’s another perspective—why doesn’t Apple just let us lock apps with Face ID or Touch ID? Probably because they want to keep their ecosystem “simple” (aka, controlling). Instead, they push these convoluted hacks like Guided Access. Honestly, Guided Access feels like it was designed for parents to stop kids from spamming YouTube videos, not for real privacy needs.

If Apple’s own tools feel too clumsy, some people jailbreak their iPhones to install third-party tweaks that enable actual app locking. Not saying you should jailbreak because it voids warranties and risks security issues, but people do it for this exact reason. If you’re not ready to dive into the wild west of jailbreaking, checking out protective apps like ProtonVPN or even password managers that double as vaults for sensitive info might help. They won’t lock apps, but you can at least tuck away important data.

Long story short? Apple’s app-locking solutions are half-baked, and until they roll out a Face/Touch ID lock feature (if they ever do), your best options are awkward workarounds or going rogue with third-party tricks. Don’t hold your breath waiting for Apple to make this easy—secure what you can and hope for better updates down the road.

Alright, so while @stellacadente and @mike34 have shared some solid methods using Screen Time and Guided Access, I gotta throw a curveball here—neither of those are great for genuine app locking. They’re workarounds at best, not true solutions. Apple seriously needs to step it up.

Let’s dissect:

Why Screen Time doesn’t quite cut it

  • Pro: It’s built-in, you don’t need any extra apps, and you can set a password.
  • Con: Using a one-minute timer to ‘lock’ apps feels like duct-taping a door shut. It’s easy to bypass temporarily by just extending the time. Effective? Meh.

Guided Access – Cool-ish but Limited

  • Pro: Great for short-term app security if someone borrows your phone.
  • Con: It’s annoying to enable every single time. Plus, it’s meant for accessibility and feels clunky. Not ideal for permanent app security.

What else you got, then?

  1. Use Notes (with Password Protection)
    Okay, so this doesn’t lock apps directly, but if you’re just putting sensitive information into apps like Notes, Photos, etc., lock specific Notes with a password/Face ID.

    • Go to the Notes app, write your info.
    • Click Share, then Lock Note. Done.
      Pro: It’s seamless integration with Face ID. Con: Doesn’t lock apps, just data.
  2. Third-Party “Vault” Apps
    Apps like My Secret Folder or KeepSafe Vault can hide and encrypt files, photos, or even private apps. Nice if you only care about locking specific files, but not functional for app-wide privacy. Pro: Tailored for privacy. Con: You’re now relying on a third-party app for security.

  3. Jailbreaking (Extreme solution)
    Want full control? Jailbreaking opens the door to custom tweaks like BioProtect or iAppLock for true app locking. But…

    • Con: It’s risky! Void your warranty, open up vulnerabilities, and if done wrong, brick your phone. Not worth it for most people—even the tech-savvy.

What Apple SHOULD Have

Look, what we need is Face ID or Touch ID to lock individual apps directly. Something simple under each app’s settings: Privacy > Lock App. No hacks, no guided-this-or-that. Until they add this feature (hello, Tim?), we’re stuck with Frankenstein solutions.

TL;DR

If you’re dead-set on privacy, the best option right now without jailbreaking is a combination of Screen Time for app time limits and password-protecting individual files using Notes or third-party vault apps. Problem is, none of these are real app locks—they’re just roads around it. Apple, we’re looking at you…
