Mobile App for Customers — Loyalty, Orders, Push Notifications
A mobile app for customers is the cheapest direct-marketing channel a retail brand owns — no Meta auction, no Google CPC, just push notifications that land on the home screen of buyers who already paid for the brand.
What a customer loyalty app includes
Loyalty engine — points, tiers, referral
Points per purchase, bronze/silver/gold tiers with escalating perks, and a referral link that credits both inviter and invitee. Apple and Google Wallet passes replace the plastic card buyers used to lose.
Personalised offers and a hidden catalogue
Offers segmented by purchase history, basket value and last-seen category — plus a private catalogue with subscriber-only SKUs, early access drops and tier-locked prices that public visitors never see.
Orders, reservations, deep links
Re-order in three taps, book a service slot, or land directly on a product from a marketing campaign via deep links. Stripe, ApplePay and GooglePay close checkout without a desktop hand-off.
Push notifications that respect the inbox
Firebase push with frequency caps, quiet hours and per-segment templates. Open rates of 8-14% on customer-base segments versus 0.4% on cold Meta ads — the maths is why brands keep the app alive.
Profile, history, support chat
A buyer profile with order history, saved cards, addresses and a live support chat in-app. A complaint that used to spawn a ticket on Instagram DM is resolved inside the app without leaking to a public review thread.
Apple/Google Wallet loyalty cards
Loyalty cards sit next to boarding passes and bank cards in the native wallet — geofenced reminders pop up near your store, points update live without re-printing plastic, churn drops because the card cannot be lost.
Who needs a brand app
Retail brands
Cosmetics, fashion, food retail with 5,000+ recurring buyers. A retention app turns one-off Black Friday shoppers into a list that pays itself back across three to four campaigns a year.
Service brands — fitness, beauty
Studios, salons, clinics with repeat appointments. Reservations, no-show reminders, a punch-card that auto-renews and an upsell push when a regular skips two weeks.
DTC brands with repeat purchases
DTC supplements, coffee, pet food, niche apparel. Subscription, re-order in two taps, referral that beats the brand's cost per acquisition on Meta inside the first quarter.
How we build it
Stack — React Native for one codebase shipping to iOS and Android, Node.js plus PostgreSQL on the backend, Firebase Cloud Messaging for push, REST integration with your e-shop, CRM and ERP, Apple Wallet and Google Wallet for loyalty cards. See also mobile app development, e-commerce development and CRM system development.

Frequently Asked Questions
When does a custom app make sense versus a PWA?
A Progressive Web App is the right call below 3,000 active buyers, or when push and home-screen presence are not the channel you intend to lean on. A custom mobile app for customers pays off above that volume — push open rates of 8-14% versus 0.4% on Meta, Apple and Google Wallet loyalty cards, and the App Store badge as a trust signal. Below the threshold a PWA is cheaper; above it the retention curve diverges in favour of native.
How long does App Store and Google Play submission take?
After the MVP build, store assets and the first internal beta, Google Play typically approves within two to five business days. Apple App Store takes seven to fourteen days for a first review and one to three days for follow-up versions, longer if a rejection requires fixes to ATT, privacy manifest or in-app purchase rules. We submit, respond to the reviewer and handle every iteration so your marketing team never touches App Store Connect.
Who manages push notifications after launch?
Your marketing team owns push from day one. We hand over an admin panel with segments, templates, scheduling, frequency caps and an A/B testing layer — non-technical staff fire campaigns without a developer in the loop. We stay on SLA for new segment logic, Firebase upgrades and store policy changes, and review the engagement dashboard with you every quarter.
How much does a mobile app for customers cost?
An MVP brand app starts at €7,200 — loyalty points, push, profile, one Wallet pass and e-shop integration on React Native shipping to iOS and Android from one codebase. A fuller build with referral, hidden subscriber catalogue, in-app chat, deep links and CRM plus ERP integration sits between €14,000 and €28,000. Quote is fixed in EUR after discovery, with no monthly licence per active user.
