What's New in Peptly

2.0.1

October 22, 2026

Fixes in this update: • Reminders keep coming on every-other-day schedules, wait for a schedule's start day, keep your times when you change time zones, and are planned again each time you open the app. • Logging from a reminder, however late, records the time it was for; if it can't, the app tells you. • If notifications are off for Peptly, the app says so, with a button to Settings. • Your peptide's name typed another way (for example, without the hyphen) counts as the same peptide, and the library search finds it. • CSV export: dates match your log, and the file opens cleanly in spreadsheet apps. • Entries from earlier versions show their amounts as they did then. • Deleting an entry from the log now asks first.
