Sparky vs AppBlock: A Gate You Earn vs a Lock You Fight
Full disclosure: we make Sparky, so we have a stake in this comparison. We’re trying to write the version we’d want to read if we were choosing between the two, tradeoffs included.
The core difference in one line
AppBlock is a toolbox of ways to block: Quick Block for an instant one-tap lock, Schedules for time or location-triggered blocking, Strict Mode for a lock you commit to breaking only with a PIN, a partner’s approval, or a cooldown timer, plus an Allowlist and a soft usage cap called Open Limit. Sparky is one way to unlock: your apps stay gated until you finish something small and real first, water, a walk, a chapter, and the gate opens because you paid for it.
Both apps use Apple’s Screen Time framework under the hood on iOS, so neither is a workaround, and both share the same underlying limitation: deleting the app (or pulling its Screen Time permission) lifts whatever it was restricting. That’s not unique dishonesty from either app, it’s how the iOS API works for every blocker and gate built on it.
What AppBlock does well
AppBlock covers more ground than Sparky does. It runs on iOS, Android, and as a desktop browser extension (Chrome, Edge, Brave), so one setup can lock your phone and your laptop together, something Sparky can’t do (iPhone only, for now). Its Strict Mode is also a genuinely stronger commitment device than an earnable gate: locking a block behind a partner’s approval or a forced cooldown timer removes the option to just talk yourself out of it, which an earn-your-way-back gate, by design, never fully removes.
If your problem is “I need my laptop blocked at the same time as my phone,” or “I need a block I’ve made it physically inconvenient to break,” AppBlock’s toolbox fits that better than Sparky’s single earning model.
Where the two pull apart
- Free tier shape. AppBlock’s free tier works, but with real caps: Quick Block maxes out at 4 hours at a time on iOS, Schedules are limited to 2-3, and Strict Mode tops out at 12-24 hours before you’d need Premium to keep it running. Sparky’s free tier caps the number of habits (five to start), not how long or how often you can use the app itself.
- What you get back for the friction. AppBlock’s tools all cost you the same thing: access, for a set window. Sparky’s gate costs you access too, but pays it back in something else: Energy from a habit you actually did. A hard day on your phone is still a day you drank water or read a chapter, because that’s the price you paid to get in.
- Five choices vs one. AppBlock’s strength, five distinct blocking tools for five different situations, is also the tradeoff: you have to pick the right mode and configure it. Sparky only does one thing, so there’s nothing to configure wrong. We compared the whole earned-time category, not just AppBlock, in our guide to apps that make you earn screen time, and went deeper on the block-vs-limit tradeoff itself in App Blockers vs Time Limits.
Which one fits you
Pick AppBlock if you need desktop and mobile blocked together, you want a Strict Mode you genuinely cannot talk your way out of, or you’d rather configure a specific tool for a specific situation than use one model for everything.
Pick Sparky if you’re on iPhone only, you’d rather earn your way back in than run out a timer, and you want a system that gives you something back (a habit actually finished) for the access you paid for, not just a block that expires.
Neither model is wrong. A forced cooldown is the right tool when you’ve already proven you can’t be trusted with an easy out. An earning gate is the right tool for the rest of the day, when you still need your phone, just not on autopilot. If you want to try the earned version, Sparky is free to start.
