A small observation
Fastly's water check-in is an optional counter in Your daily pause on Today. It records how many glasses you choose to note on the current local calendar date. It does not set a hydration target or decide how much you should drink.
A glass is a count you enter, rather than a measured volume. Different cups can hold different amounts, so treat the display as a personal reminder of the entries you made, not a precise measurement or a medical assessment.
Add or undo a glass
Tap the plus control labeled Add a glass to increase today's count. If you tap by mistake, use Remove a glass to undo it. The count stays between zero and 99; the remove button is unavailable at zero.
Wait for the change to save before adding another entry. If Fastly reports that it could not save the check-in, check available device storage and try again. A failed save should not be treated as a successfully recorded glass.
| Control | Result |
|---|---|
| Add a glass | Increase today's recorded count |
| Remove a glass | Reduce today's count, down to zero |
See the day in context
Open All daily notes from Today, or the daily journal card in Explore, to see saved days. Each day shows its water count alongside any mood and note. The counter uses local calendar dates, so a new day has a separate entry.
Adding or removing a glass preserves the note and mood already saved for that date. It also leaves your fasting timer and completed session history unchanged. You do not need to create a fasting session before recording this everyday detail.
Keep the meaning small
A missed entry is a gap in a counter, not a verdict on your day. You can leave the feature unused whenever it is not helpful. Fastly does not compare the count with other people or use it to create a score.
Water check-ins are included in explicit local JSON backups with the daily journal. They are not uploaded to a Fastly account or server, and they are not included in progress images created by Share.
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.
