What's new in the latest 2026.9.24
• New cycle list on phones: start, end, entries and length at a glance, with buttons to edit, delete or open the chart.
• Diligence now counts when you first recorded a day. Charting in the evening, or correcting an entry later, no longer counts as late — past cycles may improve.
• The chart now shows a few days beyond today.
• A clear message when the server can't be reached, instead of asking you to check your password.
• Faster loading and more reliable connections.
