I had no coding background and just shipped an iPhone app. Here's what I learned.
I've been a Product Manager in SaaS businesses for over 10 years. I can spec a product, design a flow, write a brief. What I couldn't do was actually build anything.
AI changed that. Suddenly I could bring things to life myself. For the first time I could actually build the things I'd been thinking about for years.
The first thing I shipped is Shrynk. I got fed up with media compression apps that upload your files to some server you've never heard of, don't do video, and are covered in ads. So I built my own.
It compresses and converts photos and videos entirely on your iPhone. Nothing leaves your device. No account, no cloud, no tracking.
A few things I picked up along the way:
Knowing what to build matters more than knowing how. The product decisions (what goes in the free tier, how the UI should feel, what to leave out) are where 10 years of PM work actually paid off.
Shipping is the hard bit. Not the technical stuff. Just deciding it's good enough and putting it out there.
People genuinely care about privacy. More than I expected. The fact that nothing gets uploaded has been the thing that resonates most.
Still early days but the app is live. Would love to hear what people think.

Alfie's segmentation is spot on - "no uploads" maps to two completely different buyer problems, and you're currently optimizing for the one with zero willingness-to-pay.
The insight I'd test: what if you split the positioning by user profile? Privacy-first positioning attracts privacy advocates (good fit for early feedback, low LTV). Speed-first positioning targets creators who actually have the compression problem. The actual moat might be that you've built the right technical solution (local processing) but need separate acquisition angles for each buyer type. You could even A/B test positioning on App Store screenshots without changing a line of code.
For an iPhone utility like this, I would test the privacy angle in App Store screenshots, not just the landing page. A lot of buyers decide from search results plus the first 2 screenshots, before they read the story.
One simple split: screenshot 1 as "Compress videos without uploading them" versus "Make huge videos small in seconds." Same product, different buyer promise. If privacy is really the hook, it should show up in App Store page views to installs, not just positive comments from makers.
It’s really great that you were able to bring your own idea to life. AI can truly make things possible that used to feel unimaginable.
I used to be just a computer enthusiast, and the difficulty of programming felt far beyond my reach. But now everything has changed. With AI, I’m able to turn my ideas into real products.
I’m grateful to be living in this era, even though I don’t know how far AI will go in the future.
"No uploads" is a privacy signal that attracts two completely different buyers. The privacy-conscious user wants local processing because they don't trust cloud services — and they have a $0 willingness to pay. The content creator who needs to compress a 4K video before posting to TikTok wants speed, not privacy — and they'll pay $5/mo for batch processing. Your positioning optimizes for the buyer who will never pay, while the creator who would pay thinks "this is for paranoid people, not me.
The privacy point is interesting because you said it surprised you.
What are you seeing that tells you it’s actually driving interest — are people mentioning it unprompted, choosing Shrynk because of it, or is it mainly the part of the message getting the strongest response?
