Save workout videos on Instagram or TikTok. Never actually follow them.

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.

Launched Jan 4. Early numbers: 400 downloads $568 revenue 62% installs from App Store search 13% product page conversion 0 crashes so far

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.

I built FitSaver — an iOS app that imports workout videos and converts them into structured routines you can actually follow.

It’s not trying to compete with trainers or AI coaching apps. It solves a simpler problem: people save workouts, but rarely turn them into usable plans.

Some interesting things I’ve learned since launching in early January: Most paying users are 35–55, not 20-somethings. The biggest pain point isn’t discovering workouts — it’s organizing and following them. Users describe it as a “workout video compiler,” which wasn’t language I initially used but turned out to be accurate. Several reviews mention that scrolling at the gym is the real friction.

A few actual user quotes:

“Other apps just have set workouts that aren’t as customizable as I’d like — this app provides that customization.”

“I scroll Instagram all the time and saving workout ideas is a mess. This was super helpful.”

“There’s nothing worse than scrolling social media or notes in a busy gym. This solves that problem.”

The app is currently search-driven (App Store search is ~60% of downloads), so I’m mostly focused on product and retention rather than paid marketing.

Would love feedback on: Whether this problem resonates outside fitness If organizing saved content into structured systems is a broader pattern What you’d build next in this niche

Happy to answer technical or product questions.

This started as a personal frustration.

I save lot of workout reels on Instagram/TikTok but when I’m at the gym, they’re basically useless — lost in a messy “Saved” folder and impossible to find again.

I wanted a way to turn those short clips into actual workouts I can follow.

So I built an app: Here is the quick MVP demo of the app: https://vimeo.com/1144764933?fl=pl&fe=sh

Paste an IG or TikTok reel link Extracts the exercises + sets/reps Automatically creates a structured workout card Lets you save, tag, organize, and even build full programs from your favorite creators Sort by “Chest”, “Glutes”, “Push Day”, etc.

It feels like having a personal library of every workout you’ve ever saved.

I genuinely feel this is kinda Genz fitness app.

There are moments in college when I honestly think, “If only my mom called me right now, I’d have the perfect reason to step away.” • Stuck at a party that’s getting overwhelming • Sitting through a convo you don’t want to be in • Or just needing a little reassurance when you’re alone

It made me realize how powerful a simple, well-timed call can be.

Do you think this is something every college girl needs — a way to get that “mom call” exactly when you need it?

After 2 years dwelling in the indie hacking and buildinpublic. I realize that it's about marketing and not the idea. You can even sell peanuts online if you crackdown marketing. So what is the real use of all the apps? I think every app in the niche has value that it's more than enough to achieve what user wants to do.

I can pinpoint 100 habit tracker apps literally doing the exact same thing but able to make money.

What are your thoughts? Do you agree?

I’ve always faked phone calls to get out of awkward moments — waiting alone at a café, stuck in small talk, or even a meeting that’s going nowhere. Pretending worked sometimes, but honestly it often felt more awkward than the situation itself.

So I started tinkering with a small project called ComfortCall: an app that actually calls your phone from a real number with short, natural scenarios (like a friendly check-in, a colleague reminder, or a safety call).

I’ve been testing this idea with a small waitlist and people have already suggested really interesting use cases I hadn’t thought of — things like: Needing a “mom call” to gracefully leave a friend’s house Having an out when strangers stop you with uncomfortable questions Feeling safer on a late-night walk Escaping a family gathering without guilt

My question to HN: What other scenarios come to mind where a real, believable call could give you a graceful exit?

Curious to see what this community thinks — it’ll help me shape what to prioritize for the MVP.

Thanks

Crowds always triggered me — busy cafés, parties, subway stations, someone talking on the phone next to me loudly. I'd feel the anxiety rising but had no graceful way to leave without drawing attention.

I usually try wearing my AirPods and listening to music to evade talks happening around me. But not every time I can wear earphones and listen to music.

One day, my phone rang right when I felt trapped. Answering it gave me the perfect out. Suddenly I wasn't "that person freaking out," I was just "someone who got a call." That shift was a lifesaver. Now I trigger a call whenever I feel panic building. It sounds so simple, but it breaks the spiral and gives me a believable exit every time.

Now I'm building an app that phone calls me whenever I need it.

I’ve noticed that whenever I’m in uncomfortable social situations (like standing alone at a café, or stuck in small talk I don’t want), I instinctively reach for my phone and pretend I’m on a call.

It started as a way to avoid eye contact, but now it’s almost my go-to “defense mechanism.”

Sometimes I even wish my phone would actually ring at those moments, so I’d have a natural excuse to step away.

Does anyone else do this? Is this just a “me thing,” or a common social anxiety coping habit?

I’m curious how others manage these awkward situations—do you use tricks like this, or something else that helps?

I've been experimenting with using GPT-4 to turn financial tracking into something as simple as chatting with a friend. Instead of using spreadsheets or budgeting apps with rigid inputs, I created a personal finance assistant where you just talk to it:

“Spent ₹300 on lunch” “Paid ₹12,000 for rent” “Freelance income ₹5,000” “Set food budget to ₹10,000” It understands natural language, categorizes expenses, tracks monthly budgets, gives spending summaries, and even generates charts — all inside a conversational interface. Right now, it's running as a GPT with memory and a custom backend that logs transactions, handles budget rules, and supports custom categories (like “Cigarettes” or “Loans”).

I'm working on packaging it into a mobile app with a simple chat UI. Would love your thoughts:

Is this something you'd use? Any ideas on making it more useful/fun? What features would make it better than Excel or Notion-based trackers? Live demo soon — just validating interest before I go full-on.

Hey hackers, I’m thinking about building a scheduling tool like Calendly, but specifically for indie hackers. Something lightweight, fast, and focused on our use cases — like syncing with your project time zones, showcasing what you’re working on, and making it easy to book quick coffee chats or collab calls.

Before I dive in, I’d love to hear from you:

How do you currently schedule meetings or collabs?

Do you face any annoyances with tools like Calendly or SavvyCal?

What specific features would make a scheduling tool feel tailor-made for indie hackers?
