Regimen is the first effective digital therapy program that empowers you to overcome erection problems, holistically and sustainably. WHAT IS REGIMEN? Regimen is a digital therapy for erection problems (or clinically: erectile dysfunction), developed by some of the leading doctors and researchers worldwide for men like you. It was co-founded by Max, a former patient who was able to overcome his erection problems with a similar program. Regimen has the mission to empower everyone to take care of their erection, efficiently and affordably. WHAT YOU’LL GET Regimen offers a personalized program for your erection every day, including: • Workouts for better blood flow and muscular support with the result of clinically better erections • Deep insights into erections, causes for issues, remedies, and self care • Nutrition and lifestyle advice for better erections • Mindfulness exercises to calm and control the mind • Resources for additional personalized therapy options (including vacuum pump training, targeted pharmaceutical support and supplements) • Progress tracking along your journey IS REGIMEN EFFECTIVE? Yes! And that’s not surprising. We’ve worked with leading researchers worldwide to combine all research and knowledge in order to make Regimen as effective as possible. Today we know: More than 7 out of 10 Regimen customers see, on average, greater than 50% improvement in erectile function over the course of the first 12 weeks, and continue to improve in the long run. Progress is measured based on the global standard of erectile function assessment, known as the International Index of Erectile Function (IIEF-5). We also know from our clients that they feel the difference. Some clients tell us about better sex. About morning erections coming back. About a new body control. And our co-founder Max started the company because he has been able to overcome his own issues with such a program. WHO ARE WE? We are not another hip health care company. We are a community of doctors, patients, researchers, and scientists ourselves. Our co-founder Max is a former ED patient who tried most of the conventional treatment options (including pharmaceutical solutions, injections, and surgery) before he was able to overcome his issues with a combination of strategies, which are now included in the Regimen program. His experience inspires our commitment to serve men all over the world as well as we can. Our co-founder Dr. Wolf Beecken (MD, PhD) is a practicing andrologist and university professor. Twenty years ago, he was also an academic advisor to a large pharmaceutical company when they introduced an ED pill that quickly became the market leader. He was the doctor who helped Max overcome his issues, and in the past few years he has become further specialized in improving erections holistically. We are proud to work with an international advisory board of researchers and practitioners, including urologists, cardiologists, psychologists and physiotherapists, to ensure that this product remains state-of-the-art. They bring their expertise together in the Regimen program to offer you the best strategies to boost your erection. You can learn more about us on German and English media. IT’S FOR ALL MEN We are on a mission to enable men to self care about their most intimate issues. We know due to the pandemic and all the struggles of the past months and year(s), many of us struggle to make ends meet. Until health insurances around the world support Regimen, we are committed to make Regimen accessible to all men in need. If you can’t afford it, please get in touch with us and we’ll find a solution: get-in-touch@joinregimen.com Join Regimen.

Most people drink water. Few drink it right. Flux is the first hydration app built on circadian biology — timing your water intake to your body's biological clock, not just tracking how much you drank. It's not about drinking more. It's about drinking the right amount, at the right time, for your body. HOW FLUX WORKS Your hydration needs change hour by hour. Your brain, muscles, and metabolism follow a circadian rhythm — your water intake should follow it too. Flux calculates your personalized hydration timing protocol based on: Body weight (ml/kg formula) Wake and sleep times (circadian window) Training frequency and intensity Weather and ambient temperature Caffeine and alcohol intake Then it tells you exactly when and how much to drink — from your morning protocol (500ml within 30 minutes of waking) to your evening cutoff (2-3 hours before sleep). WHAT MAKES FLUX DIFFERENT Every other water tracker asks you to log drinks after the fact. Flux tells you when to drink before you're thirsty, because by the time you feel thirst, you're already 1-2% dehydrated. That's a 10-20%+ drop in physical performance and a measurable decline in focus. Circadian timing protocol, not random reminders Personalized to your body weight, schedule, and lifestyle Training adaptation who targets adjust automatically on workout days Weather-aware with live temperature and humidity adjustments Apple Health integration. Automatic sync with your activity data Dynamic Island and Live Activities where your is hydration status always visible Smart reminders timed to your circadian window THE SCIENCE Flux's protocols are built on peer-reviewed research in hydration physiology and circadian biology. We don't invent protocols — we implement the ones backed by published science. FOR ATHLETES AND HIGH PERFORMERS Flux is built for people who take performance seriously — athletes, biohackers, founders, and anyone optimizing their body and mind.

Verdict
The clearest difference is in-app purchases: Flux at none against Regimen's 6. Flux also leads on ads (none vs shown). Regimen's advantage is update cadence (every 3 weeks vs every 6 weeks) and iOS requirement (12.0 vs 17.0). On price and device support there is nothing between them.
