Readdle’s PDF Expert 5 is 50% Off
PDF Expert 5 by Readdle is on sale for $4.99 (50% off) right now. Here’s my video review from last fall of PDF Expert 5 on an iPhone (make sure you use the settings gear in the embedded video to watch in HD; you can also view full screen). The app is universal, which means you buy it once and then can use it on iPad and iPhone. Go here to find the discounted app.
