Is there an app that locks Instagram until you read?

Yes, a few. But first, here's how far Apple's free Screen Time gets you, and where it stops.

Written by Adam Silverness, who makes But First.

Short answer: yes. A handful of iPhone apps keep Instagram locked until you’ve done some reading. Mostly they differ in how they decide you’ve read. Before any of them, though, it’s worth knowing what your iPhone already does for free. For some people, that’s enough.

The free way: Apple’s Screen Time

Screen Time is built into every iPhone. It can’t tie Instagram to reading, but it can keep Instagram out of reach at the times you’d rather be reading. The menus changed in iOS 27, so here are both versions.

On iOS 27

Open Settings, tap Screen Time, then Time Allowances. If it asks, turn on App & Website Activity.¹
Tap Manage Categories, tap the plus button and add Social Media. Then tap the category under Time Allowances and drag its slider down to a small daily amount.²
For a reading window, go back to Screen Time, tap Screen Time Schedule, turn on Schedule and tap Add Schedule. Each time window lists the Time Allowance categories it allows, so you can leave Social Media out of, say, 7 to 8 a.m.²
Tap Always Allowed, then Add Apps, and add your reading app (Kindle, Libby, Books) so it stays open whatever the schedule says.²
To make changes take a little more effort, go back to Screen Time, tap Passcode & Management, then Lock Screen Time Settings, and choose a four-digit passcode.³

On iOS 26 and earlier

Settings, Screen Time, App Limits, Add Limit. Tap a category to see its apps, pick Instagram, tap Next and set the time.⁴
For a reading window, tap Downtime, then Scheduled, and set the start and end times. Add your reading app under Always Allowed.⁴
With a Screen Time passcode set, turn on Block at Downtime. Then apps are actually blocked during downtime, instead of showing a reminder you can choose to ignore.⁴

Where Screen Time stops

Screen Time limits by amount and by time of day. It doesn’t do order. Nowhere in its settings can you say “Instagram opens after 20 minutes in Kindle.” A schedule can keep Instagram closed from 7 to 8, but if you spend that hour staring at the ceiling, Instagram still opens at 8:01. And if you finish your chapter by 7:15, it stays shut anyway.

Limits are also easy to wave past. Apple’s own guide says that by default, Screen Time limits can be ignored once they’re reached.⁴ A passcode helps, but on your own phone, you’re the one who knows the passcode. That isn’t a flaw so much as a fact: it’s your phone.

Apps that unlock Instagram after you read

Third-party apps use Apple’s Screen Time framework to put a shield over Instagram, then lift it once you’ve read. The real difference is how they check:

Scan a page, answer a question. Read to Unlock has you scan any book page and answer a quick comprehension check to earn minutes.⁵
Read inside the app. ReadBlock keeps apps blocked until you reach a daily goal of 5 to 20 pages, read from EPUB books you upload.⁶
A short article and a question. CurioLock unlocks an app after you read a short article and answer a question about it.⁷
Count the minutes you already read. But First, the one I make, lets Screen Time count your minutes in the reading apps you already use.

If you want proof that you understood the page, a quiz-style app is the better fit, and the scan-a-page kind works with paper books. If you’d rather keep reading where you already read, counting minutes is simpler.

Where But First fits

You pick the apps that wait (Instagram, TikTok…) and the apps that count (Kindle, Libby, Books, Duolingo, a Bible app…). Instagram stays locked each day until you’ve spent your own daily goal, say 20 minutes, in the apps that count. Then everything opens until midnight, and locks again tomorrow.

Apple’s Screen Time counts the minutes, so there are no quizzes, no page photos and no timer to start. That also means it trusts you. Leave Kindle open on the table and the minutes still count. It’s built for people who want the help, not for outwitting yourself.

Free covers the complete loop: one locked app and one counting app, which is exactly Instagram and Kindle. Pro adds unlimited apps, website blocking and strict mode, for $29.99 a year with a 7-day free trial, $3.99 a month, or $49.99 once.⁸ There’s no account and no analytics, and nothing leaves your phone. You can always delete it or turn off its Screen Time permission, and everything opens. It’s iPhone only, iOS 16 or later.

FAQ

Can Screen Time lock Instagram until I read? Not directly. It can limit how long and when Instagram opens, but it has no setting that unlocks one app after time spent in another.

Is there a free app that locks Instagram until you read? But First’s free plan covers one locked app and one counting app, enough for Instagram and Kindle. The other apps here are free to download with in-app purchases, so check each listing for what’s included.

Can I get around these apps? Yes. You can delete any of them or turn off their Screen Time access. They work best for people who want the nudge.

Does it work with paper books? Minute-counting apps need a reading app on the phone. Scan-a-page apps like Read to Unlock work with paper books.
