Design Materials is an offline material reference guide trusted by hundreds of Engineers, Architects and Designers all over the World. The App was created to be a personal tool to help me take design decisions during the concept ideation of industrial products, in particular for 3D printing. Due to high demand, I decided to make it public and share it's information and power. Basically, it provides the fundamentals for most design/engineer materials on the market, based on reliable and curated academic sources. In addition, you can now create and manager your own Material, Resin or Filament data. Finally, the App features Apple Intelligence (AI) with a pair of Entity Masters in material engineering and STEM: HAL 9000 and Elemento, which can be accessed 24/7 while being on or offline (no internet). The guide contains material categories such as polymers, metals, naturals and more. All of these include synthetic, organic, bio-degradable, plastic, and much more subcategories. Each material contains information such as: About, Properties, Tags, Applications, Types and Photos. HAL 9000 & Elemento (AI entities): The legend of HAL is back. Ask anything from space to robotics or biology, HAL and Elemento are Gods of material engineering and science. HAL does precise flawless analysis while Elemento brings fresh human creativity with an attitude. In addition, you can choose the Tone of AI: Formal, Friendly, Direct or Arrogant. Both AI Entities work offline 24/7. Other features includes: • AI Chat with HAL 9000 or Elemento • Material Packs (subscribers) • 3D-model viewer/import/export • Object Capture: Scan Objects • Favorites section • Offline reference (no Internet needed) • Long list of properties per material • Save Notes per material/resin/filament • Create Designs using Apple Pencil • Support for all iPhone screen sizes • Dark Mode • iPadOS support • MacOS support • Continuous Updates with New Content • UNIVERSAL PURCHASE - One Payment for all Devices New Pro version auto-renew subscriptions: - 1 year (Gold) | 3 month (Silver) | 1 month (Bronze) subscriptions* - Access to all material database ABOUT SUBSCRIPTIONS • Payment will be charged to iTunes Account at confirmation of purchase. • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period.

I went to the material and clicked design then I readied my pencil and then clicked the screen to draw my material and It didn’t work, so that’s why I’m asking how to design materials? **Developer response:** Hi there. Thanks for the review. In regards to your question, you need to press "Edit" for the pencil to work. Hope that helps. New update now supports Filament management for 3D printing 🧵 ### 2/5 — Subscription? *2022-04-30, version 3.4* Unless the content is being revised weekly, it may be more sensible to just have notes on ones phone. **Developer response:** Design Materials is constantly updating. Subscriptions are needed to cover the maintenance cost of development. Are you able to create your own Materials using the notes app? That update is coming soon. ### 1/5 — Why? *2022-03-31* Why make an app and put it on the App Store if your customers have to pay just to try it? And on top of that it’s not cheap, it’s easier just to Google what you’re looking for. That’s where they got the information from. Don’t waste your time, money, and storage on your device for this. Worthless, bait and switch application that advertises itself as a “free app” then when you tap on the first thing an ad-wall pops up wanting money. I give it a negative 16 stars. **Developer response:** Ignore the bullies and try the App for yourself 😉 ### 1/5 — No free functionality *2020-03-14* You can only see two in free mode and you might as well use Wikipedia instead. A nice idea for an app if it was free, and if it was better organised with consistent layout and bullet points making it faster to read **Developer response:** Thanks for the feedback. Sources are from selected Academic Material Design Books, not Wikipedia. New updates address these issues. ### 4/5 — Bought subscription but still don’t have access *2019-10-05* I bought the silver subscription but it doesn’t let me access all of the materials, it’s as though I never bought it. This is frustrating and there’s nowhere to ask how I can fix it. Other than that it’s a fantastic app and I love the layout **Developer response:** This issue has been fixed with the latest update (2.0). Thank you for reporting it. Best regards! ### 1/5 — Wow *2016-11-06* Only few material listed and the rest it in-app which not mention not at the option row. And the most impressive thing it's instantly crashed! 🙌🏻 **Developer response:** False review. User clearly wants to affect the App's ratings and sales. The App works just fine, no crash at all. And of course there are in-app purchase because we don't work for free. ## Frequently asked questions about Design Materials ### What is Design Materials?
