Have you ever tried going on a shopping spree for new fabrics (in physical stores or online), only to feel completely lost by not knowing exactly how you would use that nice-looking piece of fabric, and end up purchasing the wrong thing - or purchasing the right thing, but in the wrong quantity - or worse, still: Leaving empty-handed? If your answer is "yes", then Sewing Patterns will be your indispensable companion in the future. The inspiration in the form of your pattern library is right at your fingertips, wherever you go, and you can easily make sure that you purchase the right fabric in the right quantity - and with the right accessories. The app also helps you find inspiration on how to best make use of your current stash of fabric. The app lets you gain the perfect overview in a single place, whether your patterns are purchased, found in magazines, or your own creations entirely. You can categorize your patterns based from standard garment types, or create as many of your own categories as you like. You can have your patterns sorted alphabetically, by most recent usage, or in any particular order you like. Each pattern can be associated with as many categories as you wish. It is entirely up to you how many details you want to register for your individual patterns, but the more details you supply, the more help you will find in the built-in filtering function. When browsing your patterns, only the filled-in information is shown, so you won't have to deal with lots of empy fields. Using the camera, you can supply your pattern details with pictures of the model, the instructions, or perhaps of the finalized garments. You can add as many pictures and PDF files as you like, both for your categories, your patterns and your fabric. Use the Filter function if you need to search for a specific pattern in your pattern library, or just need inspiration for your next project, based on a specific piece of fabric. In all aspects, Sewing Patterns is an indispensable app, for the experienced seamstress and the newcomer alike!

Verdict
The clearest difference is price: SeamStack at Free against Sewing Patterns's $5.99. SeamStack also leads on update cadence (daily vs every 6 weeks) and rating (5.0 vs 4.7). Sewing Patterns's advantage is ads (none vs shown) and ratings volume (252 vs 32). On in-app purchases, device support and iOS requirement there is nothing between them.
