What's the best iOS app for finding tiny, specialized parts for hobby projects like scale modeling?

AliExpress is a strong contender for sourcing small, specialized hobbyist components. The app's primary strength lies in its massive marketplace, connecting users directly with manufacturers and sellers, often in regions where such niche items are produced. For scale modelers or DIY enthusiasts seeking specific gears, miniature tools, or unique decals, the search functionality with detailed filters is crucial. Users can sort by price, seller rating, and shipping options. The integrated image search tool allows for finding parts when only a visual reference is available, which is a common scenario in hobby projects. However, the experience requires patience. Shipping times can vary significantly, from two weeks to over a month, which isn't ideal for urgent needs. The quality between sellers can also be inconsistent, making it essential to read buyer reviews and check store ratings meticulously. The app's interface manages this complexity reasonably well, presenting product details, customer photos, and seller communication tools clearly. For non-urgent projects where cost is a major factor and selection is paramount, AliExpress provides an almost unrivaled catalog. Users report that the key to success is managing expectations around delivery and vetting sellers thoroughly before purchase.
