# Shopify apps. And iPhone apps > Shopify apps on the Shopify App Store (Returns & Withdrawals, GEO Optimizer, Receipts Register, AI Chat), the Tensor theme and Scontrik for iPhone. Canonical URL: https://ifgdigital.com/en/ifgdevelopment/ · Language: English · Updated: 2026-10-15 IFG Development is the software division of IFG Digital: apps and themes for Shopify, iPhone apps, web apps. Four apps are already published on the Shopify App Store. They are in-house products, developed by Francesco Guiducci and distinct from custom development for clients. ## Who the products are for Every product is built for a specific audience and a concrete task. - **Shopify merchants**: The apps cover recurring store tasks: handling returns and withdrawals, optimising technical signals for SEO and GEO, keeping the register of receipts in order, answering customers on the storefront. - **Anyone designing a storefront**: The Tensor theme offers an Online Store 2.0 base with five presets and flexible merchandising, without a page builder. - **Anyone who wants to keep purchases in order**: Scontrik, for iPhone, keeps proofs of purchase and helps manage warranties, returns and reminders. ## Tools for people who sell Apps designed for real operational problems of Shopify merchants. IFG Resi & Recessi (returns and withdrawals), IFG GEO Optimizer, IFG Registro dei Corrispettivi (register of receipts) and IFG AI Chat are published on the Shopify App Store; for the others, availability and status are shown on the IFG Development pages. - [IFG Resi & Recessi](https://apps.shopify.com/ifg-eu-returns): Online handling of return and withdrawal requests linked to Shopify orders. - [IFG GEO Optimizer](https://apps.shopify.com/ifg-geo-optimizer): Audit and optimisation of the technical signals that help SEO, GEO and catalogue readability for AI systems. - [IFG Registro dei Corrispettivi](https://apps.shopify.com/ifg-registro-dei-corrispettivi): Preparation and reconciliation of the register of non-invoiced sales, starting from orders. - [IFG AI Chat](https://apps.shopify.com/ifg-ai-chat): AI assistant for the storefront, based on the store’s real data, with WhatsApp and Telegram channels. - **IFG WebP Image Optimizer**: Image conversion to WebP with the original preserved. - **IFG Build Your Box**: Mix & Match builder with a fixed box price and selection rules. - **IFG Reviews**: Collection, moderation and publication of product and store reviews. ## Tensor Premium Online Store 2.0 Shopify theme with five presets, flexible merchandising and a storefront journey designed without a page builder. ## iPhone apps The current focus of the consumer apps is Apple, without limiting the line to a single platform. - **Scontrik**: Keeps proofs of purchase and helps manage warranties, returns and reminders, with processing on the device. It is the first consumer app of IFG Development. - **Sudoku Unbound**: A native Sudoku app for iPhone, in development: it is not yet available on the App Store. ## Simple to use. Easy to maintain Carefully designed interfaces, dependencies kept to what is needed and behaviour verified before release. Every product starts from a problem observed in the field, often during Shopify projects. ## From the observed problem to release Products start from a problem observed in Shopify projects: a repetitive task, an obligation that forces people into spreadsheets, a function the theme does not offer. First the minimum useful scope is defined, then it is developed, then its behaviour is verified in real conditions before release. The criterion is to keep the interface simple and dependencies few: fewer components mean fewer points of failure and more predictable maintenance. ## What they are built with Shopify apps use the platform’s own tools: embedded apps, Theme App Extensions, APIs and webhooks. For consumer apps the current focus is the Apple ecosystem. Web apps follow the same criteria: ease of use, few components, verified behaviour. ## Development for clients A published app covers a common need and installs from the Shopify App Store. Custom development is for when a store’s process is specific: integrations with management systems or external services, particular logic, theme extensions. Embedded apps, Theme App Extensions, Liquid sections, and integrations through APIs and webhooks are delivered through IFG eCommerce, with a preliminary analysis before development. - [Shopify development and integrations](https://ifgecommerce.com/pages/servizi) ## Where to find each product The four published apps have a listing on the Shopify App Store, with description and installation.
