I really like the Olive Tree ESV with Strong’s, and have used it for several years. Being able to add my own notes and have them remain update to update is a super feature. This latest update, though, has taken things down a notch. When using the Goto button to search, it often is now off by several verses. The scrolling is also noticeably slower and somewhat spotty. My iPad is a couple years old, so in theory, it might not be as up to the task, but it was working perfectly before the update.
