Worth being precise about up front: several unrelated products have used the name "Offtime" over the years, including an older German-made app whose current status is unclear and possibly discontinued. This comparison is specifically about the currently available iPhone app called offtime, built by independent developer Louie Gaiser, which takes a genuinely distinctive approach — unlocking blocked apps requires physically scanning a QR code or NFC tag, deliberately placed somewhere that takes effort to reach, rather than anything you can do from the couch. Louie Gaiser has described the app in interviews as a deliberately low-tech answer to a high-tech problem — a piece of paper or a cheap tag doing a job that a much more complicated software system might otherwise try to solve.
What offtime actually does
You choose apps to block, then set up a physical QR code or NFC tag as the unlock key — placed, deliberately, somewhere inconvenient (another room, a drawer, wherever makes returning to your phone enough of a chore to matter, and different for every user depending on their own home and habits). There's no software toggle to disable the block; scanning the physical key is described as the only route back in, by the developer's own design and marketing. Pricing runs from a weekly plan up to a one-time lifetime purchase, giving you some flexibility in how you commit to the idea. The app also lets you register more than one QR code or tag, so a household could set up separate keys in different rooms, or a single user could keep a backup key somewhere else in case the primary one goes missing.
Where offtime is honestly the better pick
Placing the unlock key somewhere physically inconvenient is a genuinely clever, low-cost way to add real friction without needing dedicated hardware like Brick's or Unpluq's — you can use a printed QR code instead of buying a device, which means the barrier to trying the idea is essentially zero beyond a piece of paper and a bit of planning. For anyone who wants that spatial-friction idea without the upfront hardware cost, that's a real advantage worth naming plainly. Because the barrier is something you make yourself, rather than something the company ships you, offtime is also unusually easy to try immediately — there's no waiting for hardware to arrive in the mail before the core idea can be tested.

The one mechanical difference that actually matters
offtime's friction is spatial, like Brick's or Unpluq's, but achieved without dedicated hardware — a printed QR code or a cheap NFC tag does the job, placed somewhere that costs you a genuine trip to reach, whether that's the far side of your apartment or a drawer you deliberately don't open often. Mr. Grummel's friction is entirely digital and portable: the question travels with the phone, so there's nothing to set up, print, or leave in another room in the first place, and the app works exactly the same way whether you're at home or somewhere entirely new. One trades a little setup effort for a very strong physical deterrent; the other skips the setup for a mechanism that works anywhere, immediately, with no preparation required. It's also worth noting that this specific approach sidesteps a real weakness of pure hardware products like Brick — if you lose a printed QR code, you can simply print another one in seconds, where losing a purpose-built physical device is a more serious problem.
Who should pick which
If you're on an iPhone and like the idea of spatial friction — making yourself walk somewhere to get back in — without paying for dedicated hardware, offtime's QR/NFC approach is a clever, low-cost version of that idea, and setting it up takes only a few minutes with materials you probably already have. If you're on Android, or you'd rather not set up and place a physical key at all, that's the simpler route Mr. Grummel takes instead. It's also worth deciding in advance exactly where you'll place your key before installing the app at all, since offtime's whole design depends on that location actually being inconvenient enough to matter, rather than just across the room where you can reach it without really trying. It's also worth weighing that offtime's approach depends on genuinely committing to the inconvenience — if the printed code ends up living in a kitchen drawer three feet from your couch, the friction it's supposed to provide mostly evaporates.
