Mobile Development Consulting: The Store Policy Check Before the Feature List

Updated November 2026 · Written and maintained by the Progression Agency strategy team

A plan for a membership app that sells video lessons through a web checkout inside the app has a problem before a single screen is designed: Apple’s guideline 3.1.1 says features and content unlocked inside an app use in-app purchase. Mobile development consulting finds questions like that first. It reads the business model against the App Store and Google Play rules, chooses between native, cross-platform and a web app, and turns the idea into a first release a developer can price. Progression’s team is based in New York, runs these sessions over video with founders and product owners across the US, and meets in person on request.

A lesson app that planned the wrong checkout

A hypothetical fitness studio planned to sell recorded classes through its own card form inside the app. That plan touches Apple’s guideline 3.1.1, and the studio’s private live sessions touch 3.1.3(d).

The changed plan puts recorded classes through in-app purchase and keeps private live sessions on the studio’s own checkout, as the guideline allows for real-time services between two people. The payment model changed the scope of the app, so it is checked first.

Why does payment come before features?

Because it decides which screens exist, which accounts are needed and how much of the build is store plumbing. A feature list written first and corrected later is rebuilt later.

What mobile development consulting settles before a quote

The work answers six questions in order, and each answer shapes the next. By the end, a developer can read one scope and price it.

• How does the app get paid, and under which store’s rule?
• Is it more than a repackaged website?
• Which platforms come first, and how are they built?
• What must the first release do and not do?
• What does a reviewer need to log in and see the features?
• Who will build it, and who will own the code?

Cost comes after the scope exists, not before it. For what the finished scope tends to cost by type and feature, see app development cost.

Who should be in the room?

The founder or product owner, and whoever will answer questions about payments and accounts. A developer joins when the scope is ready to test.

How the app gets paid, by store

The table sets out what each store says about each kind of purchase. Where a store’s page is silent, the cell says to check the guideline before scoping.

Apple’s guidelines treat the United States storefront differently on links to other purchase methods. Read guideline 3.1.1(a) and ask counsel before relying on that, since this page gives no legal advice.

Physical goods and services stay outside store billing

Apple says an app that sells physical goods or services consumed outside the app must use methods other than in-app purchase, such as Apple Pay or a card form. Google Play’s page lists physical goods, and physical services such as transportation, airfare, gym memberships and food delivery, as purchases its billing system does not support.

Live sessions: one to one versus one to many

Real-time services between two people, such as tutoring, medical consultations, real estate tours or fitness training, may use other methods. One to few and one to many real-time services must use in-app purchase.

• Write down every thing the app sells.
• Label each one digital, physical or a service.
• For services, note whether they are live, and with how many people.
• Check each row against both stores before scoping.

More than a repackaged website

Apple’s guideline 4.2 says an app should include features, content and UI that elevate it beyond a repackaged website. The plain advice: list what the app does that the website cannot, such as offline use, notifications, device features and faster repeat tasks.

• Offline use: what works without a connection?
• Notifications: what is worth interrupting someone for?
• Device features: camera, location, sensors, wallet.
• Repeat tasks: what is faster in an app than in a browser?

If that list is short, a web app may be the honest answer. See progressive web app development for that route.

What if the list is long?

Then an app earns its place, and the list becomes the core of the first release scope.

Native, cross-platform or a web app

Mobile app strategy development comes down to four inputs: which devices the audience uses, which device features are needed, what the team can build and maintain, and whether the budget covers two code bases.

Platform detail lives on iOS app development, Android app development, cross-platform app development and progressive web app development.

Does the first release need both platforms?

Not always. A single platform can test the idea sooner and cheaper, and the second follows once the first has users.

Getting through review the first time

Apple’s guideline 2.1 asks for final, fully functional submissions with working links, and for demo account details when the app has account-based features. The plain advice: plan the reviewer’s path through the app as a feature of the first release.

• A demo account that stays active, with its back end running.
• Notes on any feature that is not obvious.
• Working links and no placeholder text.
• An explanation of every in-app purchase.

No consultant can promise that an app passes review, and none is promised here. What the plan can do is remove the avoidable reasons for a rejection.

What is a reviewer access plan?

A short document that says how a reviewer signs in, where each paid feature is, and how to trigger anything that depends on a back end.

Choosing a mobile development partner

A build partner should answer four questions, each tied to what came before. Who owns the code and the store accounts? How are releases tested? How is maintenance priced after launch? What happens to the scope when the payment model changes?

App development partners differ in how much of the decision work they do, and some will build whatever is specified. For adding people to a team you direct, see hire app developers, and for onshore and offshore delivery models, app development outsourcing.

Is a build partner the same as hiring developers?

No. A partner covers decisions and delivery. Hiring adds people to a team you direct.

What the consulting delivers

The output is a short set of documents, written so a developer can price version one without asking what was meant.

• A model and payment memo.
• A platform decision with reasons.
• A first release scope in priority order.
• A reviewer access plan.
• A partner brief.

Progression’s method is proprietary and kept for clients. The documents are yours to keep and to hand to any developer.

How long are the documents?

Short enough to finish in a sitting. A memo nobody reads decides nothing.

Pricing mobile apps consulting

Pricing for mobile apps consulting depends on scope, is subject to change and is set in the written proposal. Consulting is a short engagement priced by scope. A build is priced from the scope it produces. Store fees and commissions are set by Apple and Google.

• Ask what the consulting scope includes and what it leaves out.
• Ask whether the documents are written to be handed to any developer.
• Ask how a build price will be set after the consulting.
• Ask what a follow-up review after launch would cost.

A first release a developer can price

The first release scope lists what ships, what waits and what the app will not do. Each item is small enough to estimate and ranked so cuts come from the bottom.

• Must have: what the app cannot launch without.
• Should have: what comes in the first update.
• Later: ideas parked until real users ask.
• Not doing: what is deliberately left out.

A scope written this way lets two developers quote the same work and be compared fairly.

Who cuts the list?

The founder or product owner, guided by the payment and review findings. The consultant explains consequences and the decision stays with the owner.

Between builds: consulting after launch

A mobile app consultant is useful after launch too. Reviewing releases, store feedback and the next scope keeps an app from drifting into a pile of requests.

For keeping an app shippable month to month, see app development agency.

How often should a review happen?

After each major release and whenever a store changes a rule that touches the app.

What this consulting does not do

Some things are outside what advice can promise. Saying so up front avoids disappointment.

• It does not promise that an app will pass review.
• It does not give legal advice on the United States storefront or any other rule.
• It does not state commission figures, which Apple and Google set.
• It does not replace reading the guidelines yourself before launch.

What it does is find the questions early, when answering them costs a meeting and not a rebuild.

Where do legal questions go?

To counsel. The consultant flags that the question exists and the lawyer answers it.
