    On the podcast: Rhys Kentish shares how he went from building quirky side projects to creating touch grass, a screen time app that keeps your distracting apps locked until you go outside and take a photo of real grass. He talks through how a rough prototype posted to Reddit and Hacker News turned into 40,000 pre-orders and 50,000 active users on launch day, why that success nearly landed him with a $20,000-a-week API bill, how a one-sentence pitch and a sense of humor became his best marketing tools, why building in public and a personal brand are the real defense against copycats, and how he’s rebuilding touch grass to turn a viral spike into long-term retention.


    Top Takeaways:
    🗣️ Say the app in one sentence, out loud, to real people
    Before building, boil the idea down to a sentence and watch faces. If they chuckle, there's something there. If they don't, that's a signal too.

    📣 Post the rough prototype, then give the viral post somewhere to go
    An unpolished mechanism demo hit the top of r/SideProject; three months of polish later it went up again with a preorder page attached, so 40,000 people could hit a button before anyone saw a price.

    🌍 If you're in Europe, post in the morning
    A launch that does well on Reddit or Hacker News before the US East Coast wakes up is the first thing they see, and then the West Coast after them. Time zones are a free head start.

    💸 Do the API math before the preorders land
    A cloud vision API that's fine for a few hundred users was going to cost something like $20,000 a week at 40,000 preorders. Three sleepless days later it ran on-device.

    🧲 Copycats are a signal, not a death sentence
    Start from the assumption that nobody's copying you; if they are, you have traction. An idea with character, plus a name people recognize, is what they can't clone.

    🔁 A viral spike isn't a business until people stay
    50,000 users on day one, and the app was the first thing they deleted when they wanted Instagram back. The rebuild chases retention, not the next spike.


    About Rhys Kentish:

A Welsh software engineer based in London with 10 years of mobile development experience, he's also built playful side projects like Beatstride and Tender, and now works at RevenueCat.

    Notas del episodio

    On the podcast, I talk with Sandeep about how a frustrated student’s struggle inspired him to create NaadSadhana, a revolutionary AI-driven app that helps singers perfect their pitch in real time. We dive into how his journey—from Microsoft and Google engineer to Apple Design Award-winning musician—shows what happens when art and technology truly harmonize.


    Top Takeaways:

    🎵 Build for Passion, Not Just Profit
    Sandeep didn’t set out to build a business—he built NaadSadhana to help one struggling student. Solving a personal, meaningful problem led to a product that resonated deeply with others. Passion-first can still lead to product-market fit.


    🧠 Invent What Doesn’t Exist

    No app could help singers practice pitch accurately. So Sandeep built one—then layered in AI to simulate a responsive, collaborative band. When off-the-shelf solutions don’t exist, invent your own, especially if you're the first customer.


    🔄 Iterate Like an Artist

    Despite winning an Apple Design Award, Sandeep rewrote the app from scratch to add more instruments and complexity. Don’t let accolades freeze you. Treat your product like a living artwork—refine, rebuild, and evolve.


    🧘 Stay Human in the Age of AI

    Sandeep calls his AI "artistic intelligence." It doesn't replace musicians—it empowers them. He built ethical constraints into the app to keep it human-feeling. Augment people, don’t automate them out of the process.


    📣 Word of Mouth Over Paid Ads

    NaadSadhana grew organically through teachers, students, and artists sharing it. No marketing team. No budget. Just a product that solved real problems and delighted users. Focus on creating “wow”—and trust the users to spread the word.

    🎛 Obsess Over Craft
    From psychoacoustics to sub-millisecond latency to modeling physical string vibrations, Sandeep sweats every detail most users will never see. Excellence compounds. When you build with care, it shows—even when people don’t know why.

    On the podcast I talk with Taiwo about building games that are meant to be deleted, finding success by leaning into low retention instead of fighting it, and how a single unconventional idea led to Apple featuring his work and changing his career.

    Top Takeaways


    🎨 Creativity Can Beat the Odds

    The games industry is so well-established that at first glance it may seem almost useless to try to enter the market as an indie developer, but all it can take is a truly original idea to pry open the gates and gain a foothold.


    📣 Lean Into Building In Public

    There’s little as scary as putting yourself and your work out there for feedback but building publicly and sharing updates on platforms like Twitter provides both an accountability boost and can be a treasure trove of free insights from your future audience.


    💪 The Power Of Persistence

    Making a living from building apps can take time, patience, and a dash of luck. When that persistence does pay off though, it can translate into a much stronger app creation pipeline once going full-time becomes an option.


    💭 Defy Imposter Syndrome

    Nowadays, more than ever, a technical background in coding is no longer a hard prerequisite to building great apps. Thanks to new tools, app creators can come from all spheres, and what unites them is one (or more) great idea(s).


    📚 Educate And Inspire

    Everyone needs to make a living, but often the most rewarding part of the app creation journey is the opportunity to educate and inspire people. These non-profit activities help lower the barrier for budding app creators and enrich the industry as a whole.
