Locked In!
Security+
On the App StoreThe baseline security certification, one domain at a time.
Studio Locked In!
Locked In!
Every Locked In! app is built from the same study engine and then written from scratch against one exam blueprint. You get the lessons for every domain, a question bank with worked explanations, a flashcard deck and glossary for the acronyms, and a tracker that remembers what you keep missing and steers the next session at it. Nothing needs a signal and nothing needs an account.

// common questions
FAQ
What do I get before paying?
A free sampler of lessons plus a limited practice quiz, so you can judge the writing before you spend anything. The remaining lessons, the full question bank, the mock exam and the complete flashcard deck are behind the one-time unlock.
Is it a subscription?
No. One non-consumable in-app purchase unlocks the app permanently, and it is enabled for Family Sharing. There is nothing to cancel.
Do I need an account or an internet connection?
Neither. There is no sign-up, no login and no sync. All content is bundled in the app, so it works in airplane mode.
I paid and the app still shows the paywall.
Open Settings inside the app and tap Restore Purchases. That re-reads your Apple ID's purchase history. If it still does not unlock, email support with the Apple ID email you purchased with.
Does this replace the official study materials?
No. It is a study companion built to be used alongside the official objectives and hands-on practice. It is not affiliated with any certifying body.
