Peter Gillan - My App Makes $600k/Year Using This Easy Growth Strategy (copy me)

Peter Gillan co-founded Stronger, a bootstrapped gamified workout tracker (strength-score muscle heatmap) built by three engineers in Northern Ireland: ~1.2M users and ~$600K ARR. Growth came from organic content: a pre-launch viral founder video, comment-reply stitch series, TikTok screenshot carousels, and a 6-second Instagram 'fade-in' format that pulled an estimated 150-300M views once they scaled it across accounts. An accidental hard paywall led them to require a trial before free use, their biggest monetization boost (~25%).

Stronger · B2C · gamified workout tracker

Est. 150-300M views, a 100M-view month; low conversion and now fading
“we discovered this one format we call the fade-in. It's about six seconds long, just fades in from black and shows an image.”

Stronger · B2C · gamified workout tracker

Adopted after a rival did it with ~10 accounts; no separate numbers
“No, I think the key is to do micro-adjustments. But AI makes that very easy to do. You can find one hook and you can just change a couple of words from it. You could change, for example, with this image here, you could change it to light mode background.”

A workout tracking app · Stronger competitor

Downloads visibly ramped up; out-scaled the team that invented it
“But they really scaled their revenue just by copying this format. And whereas we had, you know, one, two accounts posting, these guys were ripping like maybe 10 accounts, and quite quickly, I've seen their download volume starting to really ratchet up.”

Screenshots are the main money-maker; founder claim, no numbers
“But we have always tried to think, "How does this look as a screenshot?" Cuz ultimately, it's those screenshots are what make us money.”

Stronger · B2C · gamified workout tracker

Historically their best-converting channel; weaker in the past year as 20 rivals copied
“This is our main account, and it's all just two- to three-slide carousels, which perform really well for us. I think historically this has probably been a lot higher converting than Instagram. In the past year, it's probably worked less well, just cuz you've got so much competition”

Stronger · B2C · gamified workout tracker

~15K followers in week one; then hit #3 in Health & Fitness at launch
“And then we also had this little timeline thing we made in Canva, which was where we as you added up things, you could see like the Easter Island head you've lifted, a Stonehenge slab, different things like that.”

Stronger · B2C · gamified workout tracker

A series of viral videos; likely most of the account's 4.9M likes
“So, we got a lot of comments about people saying like, "I lifted, you know, I benched-pressed 220 lb for five reps. What is that?" And then we would just stitch that video.”

~25% boost, their biggest ever; few complaints, but less sharing
“Turned out we just had a bug and everyone opening the app was getting hit by a hard paywall and couldn't go to another workout unless they paid.”

Founder says they now monetize per user among the best workout trackers; no numbers

How they find each new format; no numbers given
“Look for whatever's working, not just within your industry, but in other industries. You know, if there's like a finance tracking app that's taking off, look at their formats and be like, "Okay, how could I actually reformat this, reskin this, and make it more relevant to the workout niche?"”

“We've worked with agencies a little bit before, but I think with agencies the incentives never fully align.”

A ranked gym workout app · Stronger competitor

Performed 'brilliantly' per the guest; Stronger later added ranks too
“That was one of our competitors that copied the strength score, but they kind of evolved it and went down the full gamification route. It was like League of Legends for the gym, which was such a great insight to see. They just went down one hyperspecific niche and ended up performing brilliantly because of it.”

Guest says it built a strong brand and rocketed up the charts; no numbers

“That's one of the reasons we're working on our new app, because it's an isometric, tile-based game. If you try to get Claude or something like that to do it, right now, it can't.”
