Track awake time and plan the next nap

Wake windows tracked. Guesswork gone.

SleepSpot tracks the time since your baby last slept and estimates a possible next sleep window to help you plan.

The overtired trap

A baby can become fussy or harder to settle after being awake longer than is comfortable for them, but sleepy cues and daily needs vary.

Wake windows — the stretches of awake time between sleeps — can be a useful planning reference. They are not medical targets or a guarantee that a baby will sleep at a particular time.

Suggested ranges vary by age and source, and an individual baby may differ from a chart or from one day to the next.

A timer informed by your sleep log

SleepSpot starts counting the moment a sleep session ends. You see the current wake window front and center — on the app, on your home screen widget, at a glance.

SleepSpot uses the sleep history you record to estimate a possible next window. Recent logged patterns can add context beyond a generic age chart, but the app cannot know exactly when your baby needs sleep.

You can receive a planning notification near the estimated window. It is a reminder to consider alongside your baby's cues, not a guarantee or medical recommendation.

Real-time wake timer

See exactly how long your baby has been awake since their last nap. Visible on the home screen and in the widget.

Age-adjusted baselines

Age-based reference ranges provide a starting point, while the sleep history you record adds individual context.

Planning reminders

Optional notifications near an estimated sleep window help you remember to check your baby's cues and routine.

Home screen widget

Glance at your iPhone home screen to see the current wake window without opening the app. Works with small, medium, and large widget sizes.

Real scenario

Tuesday, 10:47am

You recorded the last nap ending at 9:15. Later, the SleepSpot widget shows the elapsed awake time and an estimated next sleep window. A reminder prompts you to check your baby's cues and decide whether it is a useful time to begin the usual routine.

Common Questions

What are wake windows?

Wake windows describe the time a baby is awake between sleep periods. Age-based ranges can be a planning reference, but they are not medical targets and individual needs vary. Logging sleep and watching your baby's cues may help you notice patterns that are useful for planning.

How does SleepSpot know my baby's wake window?

SleepSpot measures the elapsed awake time from the sleep sessions you record and can compare it with age-based planning ranges. Logged history helps personalize timing estimates, but the app cannot determine when a baby needs to sleep and its alerts are not medical advice.

Can I see the wake window without opening the app?

Yes. SleepSpot has iOS home screen widgets that show the current wake window, time since last sleep, and the next nap prediction — all at a glance.

Is the wake window tracker free?

Yes. Wake window tracking, real-time timers, and widgets are all free in SleepSpot.
