I haven’t had cromu for long, but so far, I absolutely love it. The yarn and needle stash is very useful for keeping up with how much yarn you have, and it’s really helpful that you can add notes for clarity when you start a new project. The project part is amazing. You can add a PDF, pictures of the pattern, or type it up. You can also add when you want to start and finish it, what yarn(s) and hook(s) you’re using, and you can time how long you’ve been working on it. You can also mark up your image pattern (I don’t know about PDF or typed since I’ve only used an image) to add notes. You can also keep track of the patterns that are in progress, upcoming, and finished. The achievements help you stay determined, and the tools are very useful. The only problem is that it sometimes freezes, but it’s nothing a quick exit and coming back in can’t fix. The ads also aren’t even bad. You don’t have to watch anything it’s only just a little thing on the top of your patterns. I can’t believe that nobody has left a review on this extraordinary app! I’ve tried all kinds of crochet apps and this is the only one that has met my expectations! :)
Developer Response
Wow — thank you so much for taking the time to write such a thoughtful review, and welcome to Cromu! It genuinely means a lot to hear that the yarn and needle stash, project tracking, pattern markup, and achievements are all working the way we hoped. You clearly explored everything! You're also our first review, which makes it even more special. 💛 On the occasional freezing you mentioned — you're right that a quick restart helps, but we're actively working on performance improvements so you won't have to do that at all. Thanks again for choosing Cromu among all the crochet apps out there. Happy crocheting!
Amazing app
Crochet infinity
It’s good app but keeps freezing every time i use it or make a change or even scroll
Developer Response
Thank you for the kind words and for flagging this. We identified the freezing issue that was happening during scrolling and edits, and we've just shipped an update with major performance and stability fixes. Please update to the latest version — it should feel much smoother now. If you still run into any freezing, we'd love to hear from you so we can keep improving.
