Loyalty app development
A loyalty app gives customers a reason to come back and gives you data on what they buy. Athryx Tech builds loyalty apps and programmes for retailers and brands in Romania and across Europe: points, tiers, personalised offers and rewards, connected to the systems you already run.
Our work for MAM Bricolaj shows what a good loyalty app can do. The MAM+ app, with loyalty points, personalised offers and purchase-behaviour analysis, is live on the App Store and Google Play and reached 7,500 active users in four months. For FeroMarket we built an online store with personalised accounts and pricing, a loyalty programme with levels and rewards, and an admin panel for promotions.
The hard part of loyalty is not the app screen but the rules and integrations behind it. Points have to match real purchases in store and online, offers need to reach the right customers, and staff need tools to handle exceptions. We design the programme logic and the backend together with the app.
Problems we solve
- Plastic cards and paper stamps that tell you nothing about customers
- Loyalty points that do not match in-store and online purchases
- Generic discounts sent to everyone instead of offers that fit
- Programmes nobody can change without a developer
Who this is for
- Retail chains, including DIY, fashion and grocery
- Ecommerce brands that want repeat purchases, not one-off orders

Frequently asked questions
What does it cost to build a loyalty app?
It depends on the programme rules, the number of integrations and whether you need native or cross-platform apps. We scope it first and give you a clear estimate before development starts.
Can the loyalty app connect to our POS?
Yes, as long as your POS or ERP offers an API or a data export. Matching in-store and online purchases is a core part of the work.
How do you get customers to install the app?
Give them a reason at checkout: an instant reward, a digital card that replaces the plastic one and offers they cannot get elsewhere. We design onboarding that takes seconds.
Do you build loyalty apps for clients outside Romania?
Yes. We work in English with clients across Europe and can adapt programmes to local currencies, languages and privacy rules.
