Know which records you are viewing
Fastly orders main history with the newest completed sessions first. The end timestamp controls that ordering, which differs from sorting by start time or by the date you edited a note.
Make the smallest useful change
Look at the completion date when locating a session. After editing times, allow for the entry moving because the controller sorts the updated history again.
History groups completed sessions by their local end date. The week chart adds the whole duration of each matching record to that day; it does not split an overnight session across two bars.
Verify the result
Adding a journal note today to an old session does not make that session a new event. Its recorded start and end still describe the earlier session.
Preserve an honest history
If two entries look unexpectedly close, compare both sets of timestamps before deleting one. Similar durations or protocol labels alone do not establish that records are duplicates.
Time edits preserve the session protocol, goal, note, mood, and optional weight. The controller sorts by end time after saving, so a corrected entry may move while retaining the same contextual information.
A worked walkthrough
Consider two records: one started earlier but ended later, while another started later but ended sooner. Fastly's newest-first list follows end times, so the first record can appear above the second even though its start was earlier. Editing the end can change this ordering. Editing a note does not change it, because the event's completion time remains the same. This distinction helps when an older session seems not to rise to the top after you add a reflection today. The date you wrote the reflection is not the date of the session itself. If entries share similar row labels, open their action sheets and compare full dates and durations before assuming one is a duplicate. The list order provides one useful index, but the record's own timestamps remain the stronger reference for identifying the event.
Fastly is a lifestyle timer and journal. These notes explain the app and offer reflection prompts. They are not medical advice or a prescribed eating schedule.
