The short answer
Save the reference and edition, then add one sentence about why the passage mattered. Revisit a small number of saved passages regularly and read their surrounding chapters again. A useful collection is one you can understand later, not simply a large pile of screenshots.
What should I keep with a verse?
Keep the book, chapter, verse, and edition. Add a note in your own words: a question, a reason you saved it, or a situation you were praying about. Avoid treating a clipped line as a complete explanation; leave yourself a path back to the passage.
In Versomi you can save verses and write private notes on your device. The saved list is edition-specific. A paper notebook can follow the same pattern if you prefer not to use an app.
How often should I revisit saved passages?
Choose a rhythm you will actually use, perhaps one saved passage at the end of the week. Open the chapter, read it again, and ask whether your first impression still fits the context. You can remove items that no longer serve as useful markers.
If you want to remember a passage, saying it aloud or explaining it to someone can reveal what you have understood and what you need to read again. Memorization is optional; attention is the goal.
Where are my saved Versomi verses kept?
The current app keeps saves and private notes on your device. It does not provide an account or cloud-synced saved list. That makes it important to understand your device backup settings and avoid assuming that deleting and reinstalling the app will restore your collection.
If a passage is especially important to you, record its reference somewhere else too. This is a practical precaution for any collection stored locally on one phone.
