Shopify app studio
Photon Apps builds Shopify apps, starting with Photon Cart.
Photon Apps is a Shopify app studio of Simplileap Digital LLP (brand: Simplileap), based in Bengaluru, India. We design and maintain public Shopify apps for merchants who want focused tools instead of stacked widgets. Our first product, Photon Cart, is a cart drawer in public preview with optional modules for upsells, BOGO, and a free shipping goal bar. Photon Cart is not listed on the Shopify App Store yet. We ship our own products, document them, and support the merchants who install them. Write to hello@photonapps.com for access, demos, and product questions.

What we do
What does Photon Apps build?
Shopify apps for merchants, starting with Photon Cart. From first prototype through public preview, listing work, and ongoing updates, we focus on products teams can configure themselves.
Shopify public apps
We design and maintain our own Shopify apps for merchants, from first prototype through public preview, listing work, and ongoing updates.
Conversion-focused UX
Storefront experiences should feel native to the theme. We prioritize clarity, speed, and flows that help merchants grow without noisy widgets.
Performance at scale
Lazy loading, lean scripts, and careful Liquid integration so apps stay invisible to Core Web Vitals and visible to shoppers.
Markets and localization
Multi-currency, translated admin and storefront copy, and market-specific rules for brands selling across regions.
Merchant support
Documentation, onboarding, and responsive support so teams can launch campaigns without waiting on engineering.
Long-term maintenance
Shopify APIs evolve. We maintain apps through platform updates so merchants are not left on deprecated integrations.
