HackedSelf vs Soul Flow: Which Is Better in 2026?

HackedSelf is practical biohacking for longevity, written like an evidence audit instead of a hype feed. Every protocol is dosed like a protocol: exact numbers, real costs, and the caveats an n=1 experiment deserves. The flagship pieces show the method. Can a Sauna Cardiovascular Protocol Replace Zone 2? works out the minimum dose - four sessions above 175 degrees Fahrenheit - before sauna heat can stand in for aerobic base work, and says plainly where the substitution breaks down. Strength Training for Longevity Tests Your Muscle Age explains which tests actually measure aging muscle: grip strength, gait speed, and lower-body power, and why they beat how much you lift. Semaglutide Longevity Evidence Is Real but Narrow takes the most-hyped drug result of the decade and sizes it honestly, including the caveat that much of the longevity-relevant data comes from HIV-patient cohorts, not healthy adults. XPRIZE Healthspan Results, Audited Against the Rules checks a headline longevity competition against its own scoring - 90-day outcomes versus the 12 months the rules promise - and publishes the gap. The same discipline covers money math: Home Sauna Running Cost per Session vs the Gym Lounge prices the at-home heat habit per session and finds the break-even point, so readers know what the protocol costs before they believe the benefits. Zone 2 Training for Lifters, Dosed Like a Protocol translates zone-2 cardio into a plan a strength athlete will actually run, with session counts and intensity borders instead of vibes. The house rules are consistent across Longevity, Sleep, Nutrition, Fitness, and Recovery: cite what the evidence claims, never inflate an effect size, flag every n=1, and show the dose. The audience is people who self-experiment but want receipts - readers who would rather see the audit than the affiliate link. Sleep and recovery coverage follows the same audit habit, and every review states what the evidence claims and what it merely suggests, so the reader can judge the strength of each claim instead of trusting a headline. The result is a site that treats self-experimentation as a discipline with a paper trail.

What problem it solves

Most biohacking content sells certainty the studies do not contain: supplement stacks with inflated effect sizes, protocols with no dose, gadget reviews with no cost-per-use. Readers who want to experiment on themselves get marketing, not evidence, and no way to tell which claims would survive an audit.

Alternatives & competitors

Where typical biohacking blogs chase hype, HackedSelf audits: minimum effective doses (four sauna sessions above 175F), honest evidence scoping (semaglutide's narrow HIV-cohort base), competition scoring checked against the rules (XPRIZE Healthspan), and per-session cost math (home sauna vs gym lounge). Every piece states its effect sizes, its costs, and its n=1 caveats in plain numbers.

Soul Flow is a Human Design chart app. Enter your birth date, time and place to get a free BodyGraph that shows your Type, Strategy, Authority, Profile, Centers, Gates and Channels in plain language. Then use it every day with transit insights, rituals, 26 guided lessons and an AI Soul Coach that reads your chart.

Human Design combines ideas from astrology, the I Ching, the Kabbalah Tree of Life and the chakra system into a single map called the BodyGraph. Many people find their chart confusing the first time they see it. Soul Flow is built to make it understandable: every part of your chart is explained in clear, everyday language, so you can see what your Type and Strategy mean for decisions, how your Authority works, and what your defined and open Centers say about your energy.

Beyond the chart, Soul Flow is designed for daily use. Transit insights show how the current planetary positions interact with your own design. Short rituals help you build a reflective routine. The 26 guided lessons walk you step by step through the core concepts of Human Design, from the five Types to Profiles, Gates and Channels. The AI Soul Coach answers your questions with your personal chart as context, so the guidance relates to your design rather than generic descriptions.

Soul Flow is freemium: the Human Design chart is free, with optional premium features. It is available on the web at soul-flow.app, on iOS via the App Store and on Android via Google Play. Soul Flow is made by Katani Labs in Tel Aviv, Israel.

What problem it solves

Human Design charts are dense and full of jargon, so many people get their BodyGraph and do not know what it means or how to use it. Soul Flow explains the chart in plain language and turns it into daily, practical guidance.
