Currently all or none style with fonts. Pricing can be reviewed; it is expensive with annual subscription. Lifetime subscription will make a difference. ### 5/5 — PDF expert *2026-08-20, version 7.25.11* This app mage my work so easily done. The connections with other apps make it even petter for my performance ### 3/5 — En****tified *2026-08-19, version 7.25.11* This used to be my favorite PDF reader on iPad. Since a few years ago, updates every now and then would give me splash screens trying to upsell me to more features. The latest are the extremely loud AI features. Now with Preview built into iOS I’ve found myself using this app less and less. ### 3/5 — Clunky *2026-08-12, version 7.25.10* Seemed to be the top choice for easy annotation of existing PDFs. Tried to fit it into my web page editing workflow and thoroughly bounced off. Not pencil-first. Very modal. I really want Preview level annotation PLUS the ability to easily -type- notes and this feels like I’m using Acrobat Pro instead :( ### 1/5 — No longer works *2026-08-11, version 7.25.10* Can’t even open up a file from my iPad downloads. What’s the point? This was my favorite but haven’t used in a few years, clearly it’s changed for the worse. ### 5/5 — 清晰度出问题了 *2026-08-09, version 7.25.10* 我在iPhone11上使用这个软件看PDF的时候，它始终呈现出比较模糊的清晰度，但在另外一个手机上则没有遇到这个问题 ### 2/5 — Stressful *2026-08-07, version 7.25.10* Most stressful payroll experience ### 1/5 — Bad all worst ever *2026-08-06, version 7.25.10* Do not pay for it or download reap off ### 5/5 — Cool app *2026-08-01, version 7.25.9* I rarely take the time to write reviews, but 'Saylavy' absolutely deserves one. From the moment I started using it, I was genuinely impressed by how thoughtfully designed and effortlessly functional this app is. It has seamlessly integrated into my daily life, helping me stay on track and organized in ways I didn't think were possible with an application. The user interface is incredibly intuitive, making navigation a joy rather than a chore. Everything just *works* – smoothly and reliably. It's clear a lot of care went into crafting an experience that truly benefits the user. If you're looking for an app that genuinely enhances your productivity and simplifies your tasks without any unnecessary fuss, look no further. Five stars, hands down – it's become an indispensable tool for me! ## Frequently asked questions about PDF Expert ### What can I do with PDF Expert?
