Sto-Colorix Colour and architecture are intrinsically linked. For this reason, the Sto App now also provides you with an electronic access to the entire StoColor System. The Sto-Colorix App contains the well-known Colorix software as well as all colour shades of the StoColor System. The App is compatible with Apple's iPhone, iPad and iPod systems. The colours of pictures of i.e. buildings, walls, etc. that were taken with an iPhone or iPad can be changed within seconds. A conventional colour chart is, therefore, no longer necessary. The pictures redesigned using the Sto-Colorix App, along with information on the applied colour shades, can be digitally stored and then instantly forwarded via e-mail. The StoColor System Sto's classic is the StoColor System. The human visual perception forms the basis of this system. This direct link to the emotive aspect of colour is the key to the StoColor System and its intuitive use. The Sto-Colorix App is particularly user-friendly. It allows for the colour shades available in the StoColor System to be applied directly onto an object and to be subsequently sent off electronically. AC-Architectural Colours presents durable and material-oriented colours especially for building envelopes. All 300 colour shades can be delivered as silicone resin or Lotusan paints. Most of them are also suitable for coating organic and mineral external wall insulation systems. Professional colour measurements of smooth and textured surfaces can be effortlessly done with the COLORCATCH NANO system. This device incorporates a revolutionary new technology (patent pending) to accurately measure the color of smooth, structured or patterned surfaces to determine the corresponding color of the preselected swatch. NANO reads and measures 50'000 pixels separately. During reading it eliminates automatically all non-dominant colors such as shade effects and dirty surfaces. It's the ideal equipment for any tradesman in order to measure paint bases, to apply the measured values directly to a picture and to immediately send it off electronically. Sto-Colorix App and COLORCATCH NANO colour measurement systems mean: "THE STATE OF THE ART IN DIGITAL COLOUR COMMUNICATION" Due to technical limitations, colors seen in this App may not accurately reflect paint colors. To confirm your color choices refer to your color cards. ## Key features - Apply digital color shades to photos - Access entire StoColor System - Eliminate need for physical color charts - Digitally store and share redesigned images - User-friendly interface - Professional color measurement integration ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | RAL CLASSIC | $1.99 | one-time | | NCS®© | $9.99 | one-time | ## Recent user reviews (10 of 14) All indexed reviews: https://appshunter.io/ios/app/sto-colorix/id440496442/reviews.md ### 1/5 — nicht zu bedienen *2025-01-01* leider nicht intuitiv zu bedienen ### 1/5 — Pas possible sur iPad *2024-06-19* Ne fonctionne pas ### 4/5 — Funktioniert ganz gut, aber… *2024-03-06* … ohne Pencil, vermutlich nicht bedienbar. Mit Pencil funktioniert das ganz gut. Auch mit aktuellem IOS 17. Gab uns eine Vorabversion für die neu geplanten Farbanstrich unseres Hauses. Hat bei der Entscheidung ganz gut geholfen. Nervig ist die Maskierung, wenn viele Gebüsche auf dem Foto sind. ### 1/5 — Ne fonctionne pas *2023-11-03* Ne fonctionne pas sur iPad ### 1/5 — Nutzlos *2023-10-24* Leider funktioniert die App nicht mehr. Keine Ahnung, ob sie einfach nicht mit iOS 17 kompatibel ist oder ob das letzte Update Schrott war. ### 1/5 — Nicht zu bedienen *2023-07-08* Diese App ist nicht intuitiv zu bedienen und macht absolut keinen Spaß. Es könnte so einfach sein! ### 1/5 — Schrott,Frechheit *2016-10-16* Diese App ist eine Frechheit. Die Bedienung ist simpel und einfach..... Aber.... 10€ für so ein Programm ist eine Frechheit,man kann die Fotos hochladen und bearbeiten,aber die Bearbeitung ist für die katz. Die Farben decken den Hintergrund nicht,somit ist diese App zwecklos. Man kann nicht erkennen wie sein Haus in verschiedenen Farben aussieht. Finger weg!!!! Das eine Firma wie Sto sowas nötig hat ist mir ein Rätsel. Hab mir sehr viel mehr erwartet. ### 3/5 — Einkäufe *2013-12-19* Kann meine Einkäufe nicht wieder herstellen. ### 2/5 — Farbe *2012-11-16* Viel, viel zu teuer. ### 1/5 — Sto *2012-04-05* Diese geht garnicht, nur das ich etwas habe und gehen tut nix . Bitte um Klärung . Kann nur die Standorte von StO einsehen dies sehe ich auch auf der StO Seite dafür muss ich nix bezahlen . ## Frequently asked questions about Sto ### What is Sto-Colorix?
