I'm not a doctor, medical professional, or trained therapist. I'm a researcher and pragmatic biohacking practitioner exercising free speech to share evidence as I find it. I make no claims. Please practice skepticism and rational critical thinkingYou should consult a professional about any serious decisions that you might make about your health. Affiliate links in this article support Limitless Mindset - spend over $150 and you'll be eligible to join the Limitless Mindset Secret Society.

Biohacker ReviewA Gamechanger for Personal Development is a seriously addictive habit formation app and social accountability tool. is like having a coach in your phone: with you every day with motivation, coaching, and prompting. You can use the app on your smartphone or desktop and begin adding habits that you want to make a consistent part of your life. You can make up your own habits or add ones that others practice.

For example...

  • Exercising consistently
  • Reading
  • Writing
  • Practicing a foreign language
  • Flossing
  • Doing pushups in the morning
  • Meditation with HRV training tech
  • Brain training with Dual N-Back
  • Making dinner for your family
  • Having a conversation with a stranger
  • Making a cold call
  • Break out of your shell, socially
  • Or any other habits you can come up

You check-in to habits and whenever you do them it publishes to your public account profile (if you want it to - you can also make them private). You can find and follow your friends to see what habits they are practicing. You can schedule alerts and reminders for your habits.

What's powerful about is the social accountability factor that is built into the app, your friends can support your good habits by giving you props (similar to a Facebook like) or commenting on your check-ins.

Tracking matters because a quantified habit is a habituated one. allows you to track and see your consistency with your habits. It is seriously motivational to see graphs and charts of your progress. The check-in notes also work as micro-journal, it's where I keep track of what Nootropics and health supplements I'm using.

My 8-year experience with the app

I've achieved my 15000th habit check-in and so much more thanks to gamified personal accountability that the app systematizes. checkin has motivated me to consistently practice some habits that I had failed to practice consistently before...

  • Dual N-Back Training - For years I'd been hearing about the benefits of Dual N-Back training, as a biohacker, one of the most reliable ways to upgrade the RAM of your conscious mind is to consistently train your memory with Dual N-Back software, but it's so damn boring I just could never get into practicing it consistently... Months would go by in between my Dual N-Back practice sessions! Since I've added HighIQPro as a habit to my account I rarely miss a day, in fact at the time of the writing of this review I'm on an 80-day hot streak and just hit a new Dual N-Back high score.
  • Hour 1: Empire Building - This is the common sense, yet uncommonly practiced, Entrepreneurial habit of working, without distraction, ON your business (as opposed to IN your business) for the first hour of the workday. Like most digital hustlers for the longest time, I knew I should be doing this but would more often than not get distracted checking email and social media first thing in the morning. With the help of I now practice this habit six times a week on average.
  • No fap - I've no fapped for periods of months at a time as a single guy. When I got married, after a painful learning experience, my wife and I decided that we would have a porn-free marriage. And I'm proud to have made it over two years without even a peak at porn. Eventually, I removed the habit from my daily check-ins as I've totally overcome the temptation.
  If you join connect with me! I've got some wacky and seriously self-improving habits!

A few other points of feedback

  • People enjoy bragging about their healthy habits on social media. should have an option to share check-ins elsewhere.
  • Importantly the app has privacy settings for individual habits. So you can make certain habits invisible to people following you. This is great if you are using for something personal like overcoming an alcohol or pornography addiction. I wouldn't want that published on the Internet for everyone to see! On the other hand, if I wanted to join a support group for my particular issue I might like the other members of that particular group to be able to see that I was making progress. Hopefully, this level of customization is on the way from the

Browsing through the testimonials section, you can see that this app has been seriously life-changing for many lifehackers! Users have lost 50 or more pounds, started companies, competed in triathlons, and even transformed from office worker to professional dancer.
