As an Athlete it honestly helps so much with the journaling, and breath I definitely recommend. I wish there was a widget though like to put on your screen as a reminder or your streak. I just feel like that would be an amazing touch. ### 5/5 — Really helpful athletic focus *2026-07-30* I thought this would be a lot like headspace which was just general meditation which I did for a year straight but it’s much more beneficial because of the athletic focus. It’s a very high quality app too. I wasn’t sure what to expect but I’m thoroughly satisfied. ### 5/5 — Building brick by brick *2026-06-16* I feel like I’m actually getting mentally stronger and excited to see how this plays out ### 1/5 — Copy & Paste *2026-05-17* Copy and Pasted version of the wellness app model you’ve seen a dozen times: Fill out a brief questionnaire, gives you your current stats vs. your potential, a little commit to improvement button, followed by a subscription paywall. Don’t waste your money on this vibe coded app built around a recycled model. **Developer response:** We hear you, and we appreciate the honesty. Relentless is built on the MAC framework, the most research-backed mental performance system for athletes specifically. Every lesson is written and narrated by a certified mental performance coach from their real experience. This isn’t generic wellness AI content, it’s structured training. If the onboarding didn’t make that clear, that’s on us to fix. We appreciate you bringing this to our attention. ### 5/5 — 4:58 mile PR *2026-05-14* Relentless is amazing. For two seasons I haven’t been able to crack sub 5, but after beta testing Relentless for 6 weeks, I finally hit this PR ### 5/5 — Highly recommend for those struggling with motivation. *2026-05-14* As a recent Ironman finisher, building metal toughness and motivation were some of the hardest parts of my long preparation period. I’ve found this app very easy to use and super beneficial for increasing my enjoyment of workouts and daily motivation. I would highly recommend this app to anyone training in a high intensity environment. ### 5/5 — Very useful mental training *2026-05-13* As an athlete, mental toughness is really important for me because I always underperform. Relentless helps me lock in and improve in my sports. ### 5/5 — Best mental training app I’ve used *2026-05-13* One of the few apps that actually feels helpful. The lessons are short but they genuinely make a difference before competitions. ### 5/5 — Highly recommend for athletes *2026-05-12* The app is extremely user friendly, easy to use, and most importantly it’s bringing the attention to the mental side of sports in its most dire era. Not only does it help boost performance in athletes by training the mental side, but it’s also educational. I’ve learned a lot already from this app and I’m already feeling the difference in training. This is a must for any athlete that wants to perform well in their sport. ### 5/5 — Highly recommend! *2026-05-12* Mentality is something I've always struggled with, especially going into races. Relentless has helped me feel more confident going into races to perform better. ## Frequently asked questions about Relentless ### What is the MAC framework used in Relentless?
