An app that pays back with the second purchase, not the first.

We develop mobile apps for online stores where purchases repeat. First, we calculate how many repeat orders the app must bring to pay for itself — and whether that is realistic.

The calculation before launch

How many repeat purchases should the app generate, so it is not an expense

This is the first thing we calculate in a meeting. If the numbers do not add up, we will say so before you spend the development budget.

Yes / No

If the increase does not cover development and support over 18 months, we will recommend investing in the mobile website.

App – not channel acquisition. This is a retention tool for people you have already acquired.

Key screens

Four screens, where the app either earns or loses

01First launch

Value in 20 seconds

Without mandatory registration or a long onboarding. The customer sees their region, delivery options and current prices before creating an account.

02Catalogue

Search that works with one thumb

Thumb-friendly filters, browsing history and saved lists. The same catalogue as on the website, with identical prices and stock.

03Checkout

Checkout in two taps

Saved addresses and cards, Apple Pay and Google Pay, and one-tap reordering. The app must be faster than the browser here, otherwise it is not needed.

04Return

A reason to open it again

Order status, back-in-stock alerts and personal offers. A push notification is sent when it is useful, not on a marketer’s schedule.

Retention

The app’s core metric – not installation, but day thirty

Installs are easy to buy with advertising. Revenue comes from the share of people who open the app throughout the month. We design for this exact number and review it weekly after launch.

Benchmarks for products with recurring demand. For your category, we will calculate your own figures from store data, not market averages.

Technology

Cross-platform or native: we calculate, not argue

Works for most stores

Cross-platform app

One codebase for iOS and Android. Lower development cost, faster releases and lower support cost.

  • Catalogue, checkout and portal without heavy graphics
  • Release on both platforms at once
  • Changes ship weekly, not quarterly
  • Support costs approximately half as much

When the challenge requires it

Native development

Separate apps for each platform. More expensive, but with full access to device capabilities.

  • Complex animation, AR or camera work
  • A full offline mode and background processes
  • Strict interface speed requirements
  • Deep integration with system services

Data

App and website have one source of truth

  1. 01 · Catalogue

    Prices, stock and promotions from one system

    The app works through the same API as the store. If there is no API, we build it as part of the work, not as an afterthought after launch.

    API · ERP · 1C

  2. 02 · Orders

    One status in the app, email and portal

    Payments, delivery and returns follow the same processes as on the website. The customer sees the same information in every channel.

    Payment · delivery · CRM

  3. 03 · Communication

    Push notifications triggered by events, not schedules

    Your team configures segments and scenarios. We build the basics from the start: abandoned cart, back-in-stock alerts and repeat orders.

Process

How the project runs

Every stage ends with a document that remains yours regardless of whether the cooperation continues.

  1. 01

    30-minute meeting

    Category, purchase frequency, customer base and current mobile version. We will say whether you need an app.

  2. 02

    Economics and scenarios

    Payback calculation, key scenarios, integration map, first-version scope and cost.

  3. 03

    Design and development

    One-handed interface, builds every two weeks, testing on real devices and store data.

  4. 04

    Release and growth

    Publication in the App Store and Google Play, analytics setup, retention monitoring and a change queue.

Cost

We start by calculating, then budget development

We estimate development after calculating the economics. Without this, any figure would be made up.

Economics and scenarios2–3 weeks

from $2 500

Payback calculation, scenarios, integration map and first-version plan with budget.

  • 18-month payback model
  • Key scenarios and MVP scope
  • An honest answer if an app is not needed

Development app3–5 months

from $18 000

First version for iOS and Android: catalogue, checkout, portal, push notifications and store publication.

Questions

Common questions about a store app

For businesses with repeat purchases: recurring-demand products, subscriptions and frequently ordered services. If a customer buys once a year, the app will not pay back — it is better to invest the same money in the mobile website.

A first version with catalogue, checkout, portal and push notifications starts at $18,000. The exact figure depends on the number of integrations and how ready the product data is. Economic modelling before launch is a separate stage from $2,500.

For most stores, a cross-platform solution solves the challenge more cheaply and quickly. Native development is needed where complex graphics, camera work, offline mode or platform-specific capabilities are critical.

Through the same API as the website. There is one source of truth for prices and stock; otherwise the app will sell what is not in stock. If there is no API, we build it as part of the work.

From launch to store release usually takes 3–5 months: one month for planning and design, followed by development and testing. App Store and Google Play publication is a separate 1–3 week stage.

Your team manages segments, scenarios and schedules through the admin area, without a developer. We build the basics from the start: abandoned cart, back-in-stock alerts and repeat orders.

Start

We will calculate the app economics — and we will say whether it is worth doing

A 30-minute online meeting with the founder. We will review the category, purchase frequency and customer base. We will send a written summary.







    We will send confirmation and a meeting link. No presentations – straight to your numbers.
