Spain’s GymTok has officially found its own personal trainer.
A small Spanish team spent a few months turning a diverse playbook into the fastest growing fitness app in the country.
Symmetry started out as a dare, but ended up peaking at #1 in Health & Fitness on the Spanish App Store, with 100K+ installs on Android.
Symmetry’s story started with a challenge.
In the beginning of 2025, co-founders Mauro Botanes, Miguel Ortiz, and Diego Moreno set themselves a challenge: ship a new gym app in 40 days and make €10,000.
They started building in public, posting daily and documenting the entire progress.
Just three 20 year old guys with no external investment, mentors or previous experience.
On June 6, Symmetry launched on both the App Store and Google Play.
The app made over 200K downloads in the first three months, while climbing to the top spots in multiple Spanish speaking countries.
The concept is pretty simple: you take a full-body picture, AI scans it and you get a score and a personalized workout plan to reach your weight goal.
The app has a free version with all basic features and no ads. Users who want more advanced options, they can sign up to the pro subscription for €12.99/month or €49.99/ year.
Social Growth Empire
Miguel, one of the Co-Founders, already had his own personal brand, including a self-improvement YouTube channel with 350K subscribers.
Symmetry is managing a total of 55 accounts and made over 83 million views.
Breaking them down by platform, they did:
- 55 million views on Instagram across 14 accounts;
- 27.6 million views on TikTok across 39 accounts;
- 320K views on YouTube across 2 accounts.
Instagram Faceless Powerhouse
Symmetry runs three faceless Instagram accounts that are going insanely viral. @symmetry.club is the biggest one, at 25.9 million views.
It blew up by using simple, relatable and shareable self improvement hooks at the top, then adding a fade in effect that reveals images matching the hook with quick tips and guides.
The top performing videos use that same format:
- “Bro, ¿por qué estás tan feliz todo el tiempo?” yo mostrándole esto a mi bro
- “Bro, why are you so happy all the time?” me showing this to my bro
The video below pulled 3M views on July 20:
@symmetry_.app followed as second with 15.2 million views, using the same faceless strategy, but with black and white anime pictures.
- Cómo se siente cuando todos los de nuestra edad salen de fiesta y se dr*gan, pero tú y tu bro estáis intentando ser mejor cada dia:
- How it feels when everyone our age goes out partying and dr*gs themselves, but you and your bro are trying to get better every day:
This video from July 24 hit 4.5 million views.
Then there’s @symmetryybro with 11.5M views.
This account posts 3D body images that show their app ranking system.
They managed to turn a core format and “bro” hooks into 3 faceless accounts that made over 50+ million views.
A multifaceted TikTok plan
Symmetry blew up on TikTok through two main strategies. One of them is a UGC wave built around Spanish Gen Z fitness creators.
There are 19 accounts branded “name.symmetry” that have already generated 8.8M views since launching in October.
These accounts mostly post slideshow videos that share fitness tips and then show the app on the final slide.
- “Clasificando cada rutina que he hecho (como coach online con más de 10 años de experiencia y natural)”
- “Ranking every routine I’ve done (as an online coach with over 10 years of experience and natural)”
500,000 views on November 11:
Their second strategy, and also their most successful one, is using faceless non branded accounts. The only 10M+ TikTok account is one of those and is called @elpana.musculo.
This account went viral using the same format — fitness advice slideshows plus app promo. The only difference is that all the pictures are taken straight from the internet.
- #1: 5 tips to increase your muscle mass → 3.2M views and 112K saves
- #2: 10 rules for your Winter Arc → 900K views and 50K saves
- #3: Ranking the best training apps → 1.1M views and 40K saves
Numbered and a “list” hooks worked best for these slideshows.

In only five months, three 20-year-old founders turned a 40-day dare into Spain’s go to GymTok trainer.
Symmetry is still a small startup on paper, but it already owns the Spanish fitness feed. It is a clear example of how far you can scale without ever using English content.
