Hi Ladybird328,
Thank you for sharing this. I know lots of the women on this forum find it useful to keep a record like this and it sounds like the app could be a good way of keeping everything in one place, as long as (as you say) it’s safe for them to do so.
When reporting abuse to the police, your statement is evidence, so having details you wrote at the time to refer back to is always going to be useful in linking specific incidents to dates, for example, and making the statement as accurate as possible.
Take care and keep posting,
Lisa
