Microphone access is off
Playback does not need microphone access. Check and Track do. In Lullasure, open Check and tap Open Settings, then enable Microphone. Returning to Check starts its live measurement after permission is granted.
Restore a purchase
Open Lullasure Pro and tap Restore Purchases. Use the same Apple account that made the purchase. Lullasure has no separate login and never receives your payment details.
Use Play and Check with two iPhones
- On the iPhone where sound normally comes from, open Play, choose a sound, and start at a low volume.
- On a second iPhone, open the free Check action.
- With the crib empty, position the Check iPhone at approximate mattress height, keeping the microphone clear. Observe the live estimate with the phone still.
- Remove the iPhone from the crib. If needed, lower the Play volume and check again.
Background playback
A sleep sound continues when Lullasure is backgrounded or the screen locks. You can pause it with the playback button. Playback may also be interrupted by an output-route change or another app taking audio control. After permission is granted, entering Check starts microphone use; leaving Check or backgrounding the app stops that live check. A separately started Track session can continue in the background until stopped or interrupted.
What a reading means
Lullasure labels current readings as uncalibrated estimates and shows the calibration limitation beside them. Device calibration and laboratory uncertainty testing are incomplete, so absolute suitability labels are withheld. A displayed number cannot establish an accurate absolute level or infant hearing safety. See calibration status and limitations.
