System Designer is a low-code development platform for creating systems. No matter the frameworks you use and the code you write, the most important is the model that you define to create your system. System Designer helps you to design this model and to generate the classes and components to build your system. DESIGN YOUR SYSTEM WITH EASE If you look at the different JavaScript frameworks on the market, you will notice that they all have their own way to define a model, generally only with code. System Designer uses UML, a standard, to define your model. So you probably already know how to design in System Designer even if you have never run it. The definition of the model is stored on a JSON format called MSON. With MSON you can define types, classes, one to one / one to many relationships and multi inheritance between classes. CODE THE BEHAVIOR OF YOUR SYSTEM Once you have created your model, System Designer generates the skeletons of all your methods. You only have then to add your code to implement them. System Designer provides you helpers to manage your components. You can easily navigate threw your components to create your application. CREATE COMPONENTS GRAPHICALLY There is no need to code to instantiate a component. Create a component in System Designer is like creating a document in a NoSQL Database. In fact, System Designer acts as an ODM (Object-Document Mapper) to manage your components as NoSQL Documents. RUN YOUR SYSTEM You can run your system directly from System Designer. Because you have defined a model for your application, a Dynamic Type Check is done on every action of your system. All warnings are send and shown in System Designer. DESIGN ON THE GO System Designer can be used on macOS, iPad or any browsers. System Designer has a Github module to synchronize your work between all these apps. You can begin your design on your Mac and then continue it on your iPad.

You are standing in the storage unit with the door up, looking at forty identical boxes, and the thing you drove here for is in one of them. Basic Bins is the inventory you will actually keep. Photograph what goes in the box and it names itself. Print a label, scan it months later, and see everything inside without lifting the lid. PHOTOGRAPH IT, DON'T TYPE IT The reason inventory apps get abandoned is the typing. Point the camera at something and Basic Bins names it for you. Snap the drill, the Christmas lights, the box of cables, and keep moving. Corrections are one tap if it guesses wrong. Retake a photo any time, or add one to something you typed in a hurry. Add a note or a count to anything: six folding chairs, the drill that is missing its charger. Search reads both, and when nothing matches exactly it shows the closest thing rather than saying it found nothing. Your things turn up in iPhone search too. Pull down on the home screen, type what you are after, and the result says which box it is in. Tap it and Basic Bins opens there. Only your own inventory is listed, so a shared library stays private. Add what something would cost to replace, on the few things where it matters. The printable inventory totals the ones that do, box by box and location by location, and says how many it counted. Pick the currency once and every value uses it. The location screen shows what is priced so far and what still needs a price. A QR LABEL FOR EVERY BIN Print a label, stick it on the box, and the box is now searchable. Scan it with your phone and the whole contents list comes up. No opening, no digging, no lifting a tote down to find out it is the wrong one. Labels print from your own printer on plain paper or sticker sheets. Nothing to buy. BUILT THE WAY STORAGE ACTUALLY WORKS Locations hold boxes. Boxes hold items. Some things are not in a box at all, and that is fine: the bike, the ladder, the floor lamp all live loose in the location. Each location is a full-width photo of the place, so you know the unit by its orange doors before you read the name. Drag the photo to choose which part shows, or switch to a grid in Settings. Every box gets an icon you can change from its menu. Move a box to another location when the garage becomes the basement. Everything inside goes too. Drag boxes and items into whatever order you actually walk the room in. The printable list follows it. Take something out and check it out in the app, and it shows as out with your name on it. Inside the box, the item says who has it and for how long, right under its name. Put it back and it clears. The Out screen lists everything that has left, longest gone first. This is the part that stops the "I thought you had it" conversation. SHARE IT WITH THE PEOPLE YOU LIVE WITH Storage is rarely one person's problem. Invite someone and you both see the same bins, both add to them, and both know what left. Whoever you invite joins free, and their own inventory stays private. WHAT'S FREE AND WHAT'S PREMIUM Free: one location, fifty items, and the full experience of both. QR labels, camera naming, and item values are included. It is a real inventory, not a demo. Premium, as many locations and items as you have, and household sharing. Everything you cataloged on the free plan stays yours, and stays readable, if you ever stop. Every color scheme is free on both, the light default and the dark Ink included. IT IS YOUR INVENTORY, NOT OURS No account to create. Your locations, boxes, items, and photos sync across your own devices through iCloud, and they live in your iCloud, not on our servers. Export a backup any time and keep it wherever you like. Export a printable inventory or a spreadsheet for insurance, a move, or an estate, totals and your own notes included. The spreadsheet opens in Numbers, Excel or Google Sheets.
