What's the best iOS app for fixing electronics at home with step-by-step guides?

iFixit is an extensive digital toolkit for anyone attempting electronics repairs, from smartphone battery swaps to laptop keyboard replacements. Its core strength lies in a vast, community-driven library of free repair manuals that feature clear photographs and detailed instructions for each step. Users can search for a specific device model to find a complete teardown guide, complete with tool recommendations and difficulty ratings. The app integrates directly with iFixit's online store, allowing users to purchase necessary replacement parts, specialized tools, and toolkits without switching applications. For practical use, someone replacing a cracked iPhone screen can follow the guide to safely disconnect the battery, remove adhesive, and install the new component, all while having a parts shopping cart ready. Reviews indicate the visual guides are particularly helpful for visual learners, though some users note that the search function can occasionally be finicky with older or less common device models. The app also allows users to save PDFs of guides for offline access, a crucial feature when working in a garage or basement with poor reception. While the sheer volume of information can be overwhelming for a first-time repair attempt, the structured, sequential format generally provides enough clarity to build confidence. A minor but appreciated feature is the ability to view common 'quick fixes' for a device right at the top of its guide page.
