Show HN: Turn Instagram and TikTok workouts into executable gym routines
At the gym, you end up scrolling through saved posts trying to reconstruct sets and reps from a 30-second clip.
So I built FitSaver — an iOS app that imports saved workout videos and converts them into structured, editable routines you can actually execute.
It doesn’t generate workouts. It doesn’t try to replace trainers.
It just turns unstructured social content into something usable.

The surprising part: Paying users skew heavily 35–55. I assumed this would be a Gen-Z product because of TikTok usage, but older users seem much more motivated by structure and consistency.
Some user feedback:
“Saving workout ideas was a mess. This solved that.”
“There’s nothing worse than scrolling social media in a busy gym.”
“Other apps have preset workouts — this lets me customize.”
The broader problem I’m exploring:
Content discovery is easy. Execution is hard.
Curious if others building consumer tools have seen: Organization outperform discovery as a monetizable angle Older demographics convert better than younger “Saved but unused content” as a recurring pattern
Happy to answer questions about implementation, conversion, or App Store lessons.
