Which PDF reader app should I use on a phone or laptop?

You may not need an app at all. On Windows, Microsoft Edge is the PDF reader, with highlighting, adding text, saving and Copilot summaries built in; on a Mac, Preview opens, annotates, fills and signs PDFs; on an iPhone, PDFs open in Files and in Apple's Preview app; on Android, the Google Drive app opens them. If you want one app on every device, Adobe Acrobat Reader is free on Windows, Mac, iOS and Android for viewing, commenting, filling forms and signing, without a subscription; editing the text itself needs paid Acrobat Standard or Pro. On an old or slow Windows laptop, SumatraPDF is free, fast and small, and also opens eBooks and comics. Rule: use the built-in reader until it lacks something you need, then install Acrobat Reader.
