charting (reason for purchase) is wonky

I bought this for the charting, to see clearly when my snoring is most prevalent - but the chart is useless on my (quite old) iPhone 3gs. You can’t see the specifics (time, duration, decibels or recurrence clearly. The chart enlarges (poorly) making it useless to me. I tried emailing the chart to myself and it didn’t work to a gmail or other domain address.
