Who each one suits

Foqos

  • iPhone users who want a free alternative to hardware app blockers
  • Tying a block to a tag or printed code kept in another room
  • People who want a blocker with no account, ads or tracking

Worth knowing

Foqos

  • The App Store lists it as iPhone only, needing iOS 17.6 or later. The site says it is made for iPhone and points Android users to other apps.
  • Foqos for Mac is a companion, not a standalone blocker: it blocks websites synced from iPhone profiles and needs macOS 14 or later and the same iCloud account.
  • NFC strategies need an iPhone with NFC and tags you buy yourself; QR codes and the manual and timer strategies need no hardware.
  • The App Store listing shows optional tip purchases of $1.99, $4.99 and $9.99, although the site's FAQ says there are no in-app purchases.

ScreenZen

  • The app is funded by donations; its in-app purchases are optional tips, listed from $5 to $40 on the US App Store.
  • The halo companion device costs $49, ships to the US only and works with iOS 16.4 or later and Android 12.0 or later.
  • The Windows version is a direct download from ScreenZen's site, while the Mac version shares the App Store listing with the iPhone and iPad app.
  • On Android, website blocking relies on the Accessibility permission.

Key features

Foqos

App and website blocking
Profiles for work, study or bedtime each block a chosen set of apps, app categories and website domains through Apple's Screen Time APIs. Adult content and app installs can be blocked too.
NFC tags and QR codes
Tap a standard NFC tag such as an NTAG213, or scan a QR code or barcode, to start or stop a session. A profile can be set so that only an approved tag or code will stop it.
Twelve blocking strategies
The README lists twelve strategies that combine manual, NFC, QR, timer, pause-timer and temporary-access rules, for example starting in the app but stopping only with a tag.
Breaks and temporary access
A profile can carry a break allowance that is split across several breaks, a short pause before blocking resumes, or a set number of brief opens that do not end the session.
Siri, Shortcuts and widgets
Sessions respond to Siri phrases and iOS Shortcuts actions, widgets (Control Center ones included) give quicker profile control, and a Live Activity shows status on the Lock Screen and Dynamic Island.
Foqos for Mac
A companion app for macOS 14 or later takes a profile's blocked websites from the iPhone through iCloud and blocks them on the Mac during focus sessions.

ScreenZen

Delay before an app opens
A wait is added before a distracting app opens, and it can lengthen with each open. A message of your choice, such as a question to yourself, is shown meanwhile.
Interrupted sessions
Apps can be opened for short periods only, so each session ends with a prompt to decide whether to keep going.
Limits and strict blocks
Set a daily goal per app and optionally block it at the limit. Strict blocks can apply to time ranges, after a number of opens or after a set screen time.
Schedules by day and time
Settings can differ by day of the week and time of day for each app, for example stricter rules during work hours or at bedtime.
Lock mode
Settings can be locked so they cannot be changed on impulse, and the site says lock mode can prevent uninstalling the app.
halo companion device
An optional Bluetooth device, sold separately, that blocks chosen apps while the phone is inside its radius of up to 50 ft, such as a bedroom.
