LockedIn vs Doorman: Classroom Tap-In vs Campus-Wide Phone Lock (2026)

Doorman is an app on the student’s own phone that restricts it for a class period after the student taps the phone on an NFC tag in the classroom, which Doorman calls a DoorTag, or enters a classroom code. Watertown High School in Massachusetts piloted it from fall 2025, and Doorman says Middlesex County Magnet Schools in New Jersey joined in May 2026. LockedIn is also an app on the student’s own phone, so the two are closer than either is to a pouch program. The difference is what starts the lock: a tap in each room, or the campus and the bell schedule.

How Doorman works

From Doorman’s own FAQ for families:

• • The tap starts it. Restrictions begin when the student taps a DoorTag or enters the classroom code. Doorman doesn’t ask for location and doesn’t use a geofence.
• • Two modes. Focus Mode installs a VPN profile for the school and blocks social media, messaging and multiplayer games, while apps and sites the school approves still work and calls stay open. Lockdown Mode blocks every app and site; it uses Apple’s built-in frameworks on iPhone and Android’s accessibility permission.
• • Unlocks on the schedule. Depending on the school’s setup, the phone unlocks at the end of each period or stays restricted from the first tap until the end of the day.
• • Emergency Unlock. Any student can unlock the phone at any time from the app, which restores calls, texts and 911 and notifies administrators. The school can also unlock every phone at once.
• • Attendance. Doorman syncs rosters from the student information system, and a tap-in can also record period or daily attendance back to it.
• • No MDM. Doorman says it can’t stop a student removing its configuration, and that attempts to get around it are documented for administrators.

How LockedIn works

• • The campus and the bell schedule start it. At Screen Time schools the blocked apps lock when the phone is on campus during school hours and unlock after the last bell. At Guided Access schools the student starts the lock each morning with a triple-click on iPhone, or screen pinning on Android.
• • Calls home and 911 always work. At Screen Time schools the Phone app stays open; at Guided Access schools a student can step out of the lock at any time, and the dean sees that they did.
• • Workarounds are flagged by student name: a new or second device (it needs an administrator’s approval before it counts), a phone that may have deleted the app, a faked or switched-off location, time in blocked apps, and a student who never installed the app.
• • Emergency Mode. An administrator unlocks every phone on campus with one tap; each student answers “I’m safe” or “I need help”, and staff see who has answered on a live map.
• • Rosters come from Clever, Veracross, Blackbaud, OneRoster or a CSV.

The differences that matter

• • A student who skips the tap. With Doorman, restrictions start at the tap, so a phone that never taps in isn’t restricted for that period; what the school has is a missing tap-in. With LockedIn at Screen Time schools there is no step to skip: the lock follows the campus and the schedule, and a student who never installs the app is flagged every school day.
• • Location. Doorman asks for no location at all, which some families will prefer. LockedIn checks whether the phone is on or off campus during school hours and keeps no coordinates; that check is how it locks without a tap and how it spots a faked location.
• • Hallways and lunch. Doorman can cover classes, passing periods and lunch, or stay on from the first tap to the end of the day, depending on how the school sets it up. LockedIn follows the bell schedule from the first bell to the last without a tap, which is what a bell-to-bell law asks for.
• • Emergencies. Both let students reach help and let the school unlock every phone. Doorman’s Emergency Unlock restores full access to the phone and tells administrators. At Screen Time schools LockedIn keeps calls open without unlocking the rest, and its Emergency Mode adds a roll call of who is safe.
• • Attendance. If you want one tap to restrict the phone and take period attendance in your SIS, that is a real Doorman strength to weigh.
• • Other VPNs. Doorman’s FAQ says its Focus Mode VPN replaces any other VPN on the phone during the school day, including parental-control VPNs such as Bark’s, and the family has to turn theirs back on afterwards.
• • Price. Doorman doesn’t publish a price. LockedIn is quoted per student, per year, with no hardware; see pricing.

Which one fits your school

Doorman fits a school whose rule is about class periods, that wants the phone tap to double as attendance, or whose families object to location permissions. LockedIn fits a school that wants the lock to start without a daily step, that needs the whole day covered, and that wants to see and act on workarounds by student name.

Ask both vendors the same three questions in writing: what happens when a student doesn’t lock in, what the dean sees when a student switches phones or deletes the app, and what you can show your board at the end of the term.
