Building brick by brick

I feel like I’m actually getting mentally stronger and excited to see how this plays out

Copy & Paste

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.

Response from developer

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.

4:58 mile PR

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

Highly recommend for those struggling with motivation.

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.

Very useful mental training

As an athlete, mental toughness is really important for me because I always underperform. Relentless helps me lock in and improve in my sports.
