The verdict
Brick remains a strong fit for a tangible commitment device with no recurring subscription according to its official site. The best alternative depends on the failure point: choose a blocker for access, a pause for autopilot, a physical device for bypass resistance, or SideMission when the missing piece is a credible offline action.
The key difference
“Alternative” should mean an alternative mechanism, not a list of products sharing a keyword. Brick focuses on using a separate physical object to make app restrictions harder to bypass; SideMission focuses on replacement behavior.
Side-by-side decision table
| Option | Primary mechanism | Best when |
|---|---|---|
| SideMission | a reason to leave the phone, without purchasing hardware | You can put the phone down but need one satisfying next action |
| Jomo | software-only strict sessions and budgets | That mechanism matches your actual failure point |
| one sec | friction at the app-opening moment | That mechanism matches your actual failure point |
| A timed lockbox or phone shelf | a simple household-level physical boundary | That mechanism matches your actual failure point |
First, keep Brick on the shortlist if it fits
Brick is built for using a separate physical object to make app restrictions harder to bypass. Its clearest advantage is a tangible commitment device with no recurring subscription according to its official site. An alternatives page should say that plainly: switching products without identifying a mismatch usually resets setup without fixing behavior.
Before replacing it, write one sentence describing the breakdown. Examples: “I ignore the limit,” “I open the app without deciding,” “I stop scrolling but feel restless,” or “I want shared competition.” Each sentence points to a different mechanism and a different shortlist.
Four mechanisms that are often confused
Blocking removes access for a period. Friction delays access and asks for a fresh decision. Physical commitment devices move the override away from the screen. Replacement tools supply a competing action. Products may combine these, but their center of gravity still matters.
SideMission belongs to the replacement category. It does not inspect or block other apps. It asks for practical constraints and deals one hand-crafted mission. That makes it weaker as enforcement and stronger when the real problem is the blank space that appears after enforcement succeeds.
- Use native or third-party blocking when access itself is the problem.
- Use a pause intervention when muscle memory is the problem.
- Use a physical device when easy overrides are the problem.
- Use an offline-action engine when boredom or indecision is the problem.
Evaluate switching cost and attention cost
Count setup steps, recurring configuration, required permissions, account requirements, and the number of choices presented at the moment of temptation. A feature-rich product can be the right choice, but every dashboard and feed also consumes attention.
SideMission's constraint is one card at a time with three rerolls. That is not ideal for people who enjoy browsing a large quest catalog. It is deliberate for people who want the app to make a reasonable choice, then disappear while they do the activity.
Privacy and proof deserve separate checks
Read the current store privacy label and policy for each candidate. Determine whether activity, photos, location, contacts, or identifiers are collected; whether data is linked to identity; and whether a login is necessary. Labels can change, so use the source links below rather than relying on screenshots in old reviews.
SideMission's official listing describes a no-account model and says the mission profile, screen-time estimate, proof photos, and journal stay on the device unless a proof card is shared. GPS and photo proof are mission-completion options, not a public social profile.
A practical two-tool stack
The most coherent alternative may be a pair rather than a replacement: Apple Screen Time or a dedicated blocker creates the boundary, and a short menu of offline actions fills the space. SideMission compresses that menu to one context-matched card.
Run the combination for seven days and record interruption, action start, and satisfaction. Keep the smallest system that reliably changes the moment. The goal is not to maintain the most sophisticated anti-phone setup; it is to need the setup less often.
Ready for one real thing?
Let SideMission deal the next card.
Match a mission to your mood, time, budget, distance, group, and comfort level—then close the app and do it.
Open in the App StoreQuestions people ask
What is the best free alternative to Brick?
Apple Screen Time is the built-in starting point on iPhone. ScreenZen describes itself as donation-supported. Confirm current availability and terms in the linked official sources.
Is SideMission an app blocker?
No. SideMission is an offline-action replacement tool. It can complement a blocker but does not enforce app limits.
