Crocheting Patterns
Read full descriptionHide full description
Have you ever tried going on a shopping spree for new yarn (in physical stores or online), only to feel completely lost by not knowing exactly how you would use that nice-looking skein of yarn, 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 Crocheting 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 yarn 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 yarn. 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 empty fields. Using the camera, you can supply your pattern details with pictures of the model, attach PDF files for the instructions, or perhaps add pictures of the finalized garments. You can add as many attachments as you like, both for your categories, your patterns and your yarns. 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 yarn. In all aspects, Crocheting Patterns is an indispensable app, for the experienced crocheter and the newcomer alike!

Verdict
The clearest difference is price: SeamStack at Free against Crocheting Patterns's $4.99. SeamStack also leads on update cadence (daily vs every 2 months). Crocheting Patterns's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
