Jacob, read this first.

On Wednesday's call you said you want to get your own app going. This page makes it official.

One flat price, $4,200, for version 1 of your own app on the App Store and Google Play. We start now, build through December, and go live in January.

Nothing is charged today. When you accept at the bottom, the build fee is added to your Nov 22 bill automatically: one payment of $6,700 instead of $2,500.

Accept below and I'll text you this week to kick things off. -Dylan

Where we landed

Of the 36 members who told Stripe why they cancelled, 13 said a version of the same thing: they couldn't figure out how to get into the app or how to use it. The welcome email makes people set a password before they ever see a workout, and the questionnaire comes before the app. When I signed up as a test, Trainerize greeted me as "Dylansewell12."

It lands on you too:

"I basically have to onboard every single person myself."Jacob, on our Nov 11 call

People email you because they can't get in, on top of assigning every program yourself.

As you put it: "I've known this for so long... the Trainerize app is such a problem." We agreed the fix isn't another patch on Trainerize. It's your own app. Members download it, sign in once, and their program is there.

What version 1 includes

After version 1

Version 1 is the main sprint. Once it's live, there will be things we want to add and improve: sign-ups inside the app, so people who find you on the App Store can join right there (until then, new members keep signing up through your website), in-app messaging and community, and your trainer dashboard.

After this first sprint, app work moves into your monthly plan. The size of that plan depends on how much you want done each month, on the app and outside it, and we set it together.

Built in your name

Every account is yours: the store listings, the database, the video hosting. If we ever stopped working together, you'd keep all of it. Running costs are small and go on your card, paid straight to the providers, not to me: expect $25 to $50 a month, plus Apple's $99 a year and Google's one-time $25.

Timeline

Ranges, not promises to the day. Apple and Google's business checks set the pace, so their paperwork starts first.

StageWhenWhat happens
You acceptThis weekWe start the Apple and Google paperwork. Their checks take one to three weeks.
Design on your phoneLate NovemberYou see the app early and we lock the look and flow together.
The buildDecemberPrograms and tracking get built. Test versions land on your phone as we go.
Store reviewLate DecemberI submit to Apple and Google and handle their review.

While we build

I send a progress update every week and reply same-day. Small tweaks along the way just happen.

The price, and how the payment works

$4,200one time Version 1 of the J Golf Fitness app, launch-ready on both stores.
WhenWhat happens
TodayNothing is charged. Accepting below adds the $4,200 to your Nov 22 bill automatically. There's no invoice to pay and no checkout.
Nov 22 renewalOne payment of $6,700: your usual $2,500 month plus the $4,200 build, on your card on file.
Dec 22 onwardYour monthly plan continues, and app work moves into it: the launch, fixes and the improvements after. The amount depends on how much other work you want me on alongside the app. We agree it together in mid-December, before that bill.

The 30-day warranty

For 30 days after launch, anything that breaks or doesn't do what this document says, I fix at no charge. I keep an eye on the system through that window.

The fine print

Apple reviews every app by hand, and apps where members pay on the website (the way Trainerize-built apps work) sometimes get extra questions. If Apple pushes back, handling the review and the workaround is my job, at no extra cost. That can move the launch date; it never moves the price.

What I'll need from you
