These seven metrics cover how you feel and how you spend your attention. Mood, Energy and Stress are check-ins you can repeat through the day. Meditation and Deep Work are timed. Android can read Screen Time for you. Every metric is optional. | Metric | What it is | Unit and range | How you log it | Fills itself in from | | - | - | - | - | - | | Mood | How you feel | 1–10 per check-in. 1 is Rough and 10 is Great | Tap a number on the 1–10 strip. Add more check-ins through the day | Nothing | | Energy | How energetic you feel | 1–10 per check-in. 1 is Drained and 10 is Energised | Tap a number on the 1–10 strip. Add more check-ins through the day | Nothing | | Stress | How stressed you feel | 1–10 per check-in. 1 is Calm and 10 is Frazzled | Tap a number on the 1–10 strip. Add more check-ins through the day | Nothing | | Journal | One line about the day | Text, one line, up to about 280 characters | Type in the Journal sheet, then tap Save entry | Nothing | | Meditation | Time you spent meditating | Minutes, 0 or more | Start the timer, or add a session with a length | Nothing | | Deep Work | Time you spent on focused work | Hours, 0–24 | Start the timer, or add a session with a length | Nothing | | Screen Time | Your total screen time for the day | Hours, 0–24 | Type hours and minutes | Your phone, once you allow usage access | ## Check-ins: Mood, Energy and Stress Until a day has a check-in, the row shows the 1–10 strip itself. One tap on a number saves a check-in. The row then shows the day's value. Tap it to add another check-in or to edit one. * **The day's value is the average.** Check-ins of 6, 8 and 7 give a day of 7. The average shows to one decimal place, and VitaSync labels it as the average of check-ins. * **Equal values both count.** Two check-ins of 7 stay as two check-ins. * **Each check-in has a time.** On today it is the time you tapped. On a past day you can add a time or leave it out. * **You can edit or delete one check-in.** You can also change its date or time. Moving it to another day updates both days' averages. * **Opening the strip writes nothing.** A check-in only exists once you choose a number. * **A day with no check-in stays blank.** VitaSync does not put in a middle value. A higher Stress number means more stress. Mood and Energy run the other way, where a higher number is better. Stress is typed by hand in the beta. ## Journal Journal holds one line a day. It is never required. VitaSync keeps your text while you type, and closing the sheet any way keeps it. Whitespace on its own clears the entry. ## Meditation and Deep Work Both metrics work the same way. You can log a session three ways: * Start a timer and stop it when you finish. * Tap a quick length to add a session. * Enter a custom length. Each session has a time, and the sessions add up to the day. Meditation adds up in minutes. Deep Work adds up in hours. ### The timer logs to today A timer always logs to today, whichever day you are looking at. On a past day the lengths come first, because you can only add a session that already happened by hand. The timer comes below them as Start timer for today. ### A total with no sessions A total you typed in quick-add or Catch up has no times behind it. The list shows it as "Logged as a total for the day". You can remove it like any entry. When you add a first session, the total joins the list. ## Screen Time Screen Time is one number a day. Unlike Meditation and Deep Work, it is not a sum of sessions. * **Android can read it.** Open the menu, then Integrations, then Screen time. Turn on usage access for VitaSync. See [Screen time](/help/screen-time). * **VitaSync stores the total only.** It does not store a list of apps. * **You can type it instead.** Enter hours and minutes on the Log tab. A number you type wins over one your phone supplies. * **A value from your phone is read-only.** It shows a small source badge until you edit it. * **iPhone will be manual.** iOS gives other apps no way to read screen time. Screen Time saves when you leave the field. A Save button appears while your number differs from the stored one.
