Founder & Developer, Champ

I build Champ. I write the posts on this site, and I am the person who answers hello@champ.plus.

I am a developer, not a clinician. I am not a doctor, psychologist, or therapist, and nothing here is medical advice. What I can offer is that every research claim on this site links to its source, so you can check it instead of taking my word for it. If you catch something wrong, tell me and I'll correct it.

Why Champ exists

Because the weekly screen-time report never once changed what I did on a Tuesday night. It told me a number about a week that had already happened, and the only feeling it produced was a small private shame that made me want to stop opening the report.

The moment that actually matters is about two seconds long: the reach. Champ lives in that gap. Its everyday shield sits in front of the apps you pick, offers thirty seconds of something else, and then lets you decide. A blocker you can't get past is a blocker you delete. For the hours when you do want a lock, a rule or a Focus round holds until it ends, and Strict keeps a rule from being switched off early.

And it counts what you chose rather than what you failed to avoid. That is the garden.

What we won't do

  • Inflate the numbers. An earlier version of this site claimed 50,000+ downloads, a rating and a review count Champ never had, and six testimonials from people who do not exist. All of it is gone, and none of it should have been written.
  • Cite research that doesn't exist. Every statistic on this site links to a primary source. Widely repeated figures with no traceable study behind them do not get used, however good they sound.
  • Collect your per-app usage. Apple's Screen Time framework keeps per-app usage on the device, and Champ works inside that boundary: per-app usage is not uploaded. What Champ's analytics do receive, such as how many apps you guard and that a reset was completed, is listed in the privacy policy.
  • Pretend to be a health service. Champ is a habit tool. If you are struggling with something heavier than a scrolling habit, please talk to an actual professional.

How we handle reviews

Reviews on this site are real or they are absent. We don't quote a star rating or a ratings count here. Those live on the App Store listing, where Apple keeps them current. We never write a testimonial and never edit one.

A quote appears only if the person who wrote it said we could use it, with the name they chose. Reviews are asked for inside the app, through Apple's own rating prompt, so they land on the App Store where anyone can read them. If you see a review here that you cannot find there, tell us at hello@champ.plus.

If any of that sounds right, the app is free.
