Cheryl Porter is the most-followed singing teacher alive. She is a classically trained opera singer who has lived in Italy for three decades, sang for the Pope, recorded with Andrea Bocelli and Mariah Carey, and in August 2025 made her Broadway debut in & Juliet for a 13-week engagement. Her students call her Mama Cheryl. She is also one of the very few creators in this entire corpus who already figured out what her audience needs to buy. She built it. She priced it at $7.99 a month. Then she put it somewhere nobody can find it.

What Has Cheryl Porter Already Built?

A daily vocal practice subscription. Sing on the Go is a $7.99 per month product that her own page describes as "Mama Cheryl's daily vocal practice app with real coaching, real feedback, and real results in your pocket." It ships over 200 warm-ups, ear training exercises, key selection, speed control, and a pitch monitor that shows the singer what note they are actually producing while they produce it. Read that feature list again, because it is not a course. A course is content you finish. This is a practice surface you open every morning, and she says so in the copy: "Build the daily vocal habit that keeps you ready."

Almost nobody gets here. Most creators with a teaching audience sell the lesson: a $47 course, a $197 masterclass, a bundle discounted to $99. Cheryl Porter sells those too, six of them, and they run on a rented course platform. But she also understood the thing underneath them, which is that singing is a daily physical practice and the money is in the day, not the curriculum. That insight is the hard part, and she had it.

Why Can't a Singer Hear Their Own Voice?

Because you hear yourself through the bones of your own skull as well as through the air, so the sound in your head is not the sound in the room. A singer practicing alone cannot reliably tell whether they are flat. No lesson fixes that, because the problem is not knowledge. The problem is that the customer has no instrument. This is a different kind of gap from the ones creators usually chase. Most product advice sorts an audience by a habit: when in the day they act, whose calendar funds it, whether the thing gets used up. Those all assume the customer can tell whether the practice worked. Singers cannot. Neither can anyone learning a language accent, a golf swing, a welding bead, a running gait, or a potter's centering. In every one of those the performance and the perception happen inside the same body, and the body is a bad judge of itself. What closes the gap is not more information. It is a measurement. Measurement is software. It needs a microphone or a camera, it runs while the person is doing the thing, it produces a number that changes tomorrow, and it is worth paying for every single month because the reading is only useful while you are still practicing. That is a subscription with a reason to exist, which is rarer than it sounds and is exactly the thing a course cannot become by being repackaged. Cheryl Porter knows this. Her own one-line description of the product is "real coaching, real feedback, and real results," and the feedback in that sentence is a pitch monitor. She is not selling lessons in that product. She is selling an ear.

Who Owns the Vocal Warm-Up Shelf?

Nobody. That is the whole point.

Search the US App Store for "vocal warm up" on September 20, 2026 and Apple returns twelve results. Four of them are general learn-to-sing apps built by software companies. The other eight are the purpose-built warm-up apps, the exact category Sing on the Go belongs to.

App	Publisher	US ratings
Simply Sing: My Singing App	Simply Ltd	437,834
Singing Vocal Warm Ups: Singer's Friend	Robert Lumpkins	101
Vocal Warmups with Kathleen	Kathleen Hansen	38
Warm Me Up!	L.L Hunter and others	26
7 Minute Vocal Warm Up	Daniel William	24
Voice Training & Vocal Warm Up	Pavel Levin	11
VocalPro: Vocal Exercises	Hyorok Lee	10

Add the eight warm-up apps together, including the two sitting at zero, and you get 210 ratings for the entire visible category. Simply Sing, a sing-along product from a software company, holds 437,834 on its own. Rating count is roughly installs multiplied by years on the store, so it measures distribution rather than quality. That is what makes 210 interesting. The demand is proven by the sing-along numbers. The teaching shelf is simply vacant, in the same way twelve App Store searches will show you which niches are still open, and Rick Beato left the ear-training shelf open in the next room over.

24.1 million followers is distribution. A funnel page is not.

Built by Foundry builds the product a creator's audience already needs, ships it in roughly three weeks, and runs it forever. $0 upfront, revenue share, and the creator owns the business.

A Funnel Page Is Not a Storefront

Click "Get App" on her site and you do not arrive at the App Store. You arrive at a checkout page on a separate subdomain with a countdown timer and a credit card form. An iTunes Search API query for "mama cheryl" on September 20, 2026 returns zero results. A query for "cheryl porter" returns exactly one app, and it belongs to somebody else. The most-followed vocal coach in the world has never appeared on the store where recurring subscriptions actually work. That surface choice costs three things at once. It costs discovery, because nobody searching "vocal warm up" on a phone will ever see her. It costs trust, because a card form on a funnel page converts worse than an Apple sheet the buyer has already used a hundred times. And it costs the renewal, because Apple manages billing, retries, and restores, and a one-off funnel usually does not. This is the same structural trade creators make when they leave their business on a course platform, except sharper, because here the product genuinely belongs on a phone. It is a microphone product. It is already in the right hand. It is just not in the right store.

The Instrument Test

Here is the test, and it takes a minute to run on your own audience. Ask whether your customer can tell, alone and immediately, whether they did it right. If they cannot, the product you owe them is not more information. It is a measurement. It passes loudly on singers, on accent and pronunciation students, on golf and tennis swings, on running form, on breathwork, on welding, on posture, and on anyone practicing a physical skill where the performance and the perception share a nervous system. It fails cleanly on recipes, on travel itineraries, on reading, on budgeting, where the result is plainly visible the moment it happens. A test that fails on half its candidates is a test rather than a slogan. When it passes, three things follow. The product recurs, because a reading is only worth anything while the person is still practicing. The product is defensible, because the measurement gets better with every user and a PDF never does. And the product generates content on its own, because you can finally see where ten thousand students are stuck this month, which answers "what do I post tomorrow" without you having to invent it.

If Your Audience Cannot Grade Themselves

If you teach a physical skill to more than 50,000 people and you are selling courses, this section is for you. The vocal coach, the swing coach, the accent coach, the physio, the breathwork teacher, the instrument teacher. You already know the moment your product fails. It is the week after someone finishes your course, when they practice alone and cannot tell whether they are improving, and they quietly stop. You cannot fix that with another module. You fix it by putting an instrument in their hand that says "flat by a quarter tone" on a Tuesday morning when you are asleep. That is a business rather than a product launch. Somebody has to build it, put it on the store where the searches happen, price it, and then run it forever: the billing, the reviews, the App Store releases, the support queue. That is the business we are in, and the running part is the part most creators underestimate. Cheryl Porter got the hardest part right. She looked at 24 million followers and did not sell them another masterclass. She built a daily practice surface with a pitch monitor in it and priced it lower than a coffee. Then she pointed 24 million people at a funnel page, and the store that serves her category still has a leader with 38 ratings.
