Shopify apps by UBARTAS.MEDIA
Apps that show they are working.
UM stands for UBARTAS.MEDIA. We build apps for merchants who have to rely on their tools: every app shows its state, explains its numbers and stores only what it needs to do its job.
- 2 apps with help and changelog
- 2 before launch in the App Store
- 6 more coming soon
- Goal: Built for Shopify
Try it
Two demos built from the real features. Everything runs in your browser, nothing is sent.
Stock in lockstep
Three stores, one SKU. Sell, receive stock or let an import set everything to 0. The activity log writes down what the app does.

Payment methods by rules
Set up a situation. The checkout shows which payment methods appear, in which order and why. Just like the test run in the app.

Idea
Built for Shopify is the yardstick
Built for Shopify is Shopify's award for apps that meet the highest bar for speed, ease of use and integration with the admin. Shopify grants it after launch in the App Store. We build every app to these criteria from day one and check them before every release.
Like the admin
The interface is built from Shopify's own components (Polaris). Buttons, lists and the save bar sit where you know them from the admin.
Fast
Built for Shopify's thresholds for loading and responsiveness, and checked against them before every release.
Few permissions
UM Payment Methods needs two permissions, UM Multistore Sync three. No app reads customer names, addresses or emails.
Current technology
Shopify's latest Admin API, GraphQL only, Shopify Functions wherever Shopify can do the calculation itself.
What you can hold us to
Visible state
Every app shows on its home page when it last worked and what happened.
Only the data it needs
No advertising, no analytics, no customer data the app does not need.
A company in Germany
UM is run by UBARTAS.MEDIA GmbH in Soest, Germany, with a legal notice and a named contact.
