Note: Schlummer is a wellness product, not a medical device. For a reliable alarm, charge your iPhone overnight and keep the ringer on.
Yes. Schlummer is a free iPhone sleep tracker. The smart alarm, last-night snore recording, and your morning sleep score are free to use with no account and no ads. Schlummer Pro is an optional upgrade that adds long-term trends, all soundscapes, unlimited recordings, and video sharing.
No. Schlummer works with your iPhone alone, so you do not need an Apple Watch or any other wearable to track your sleep, record snoring, or use the smart alarm. Keep the iPhone charged and near your bed overnight. Schlummer treats its numbers as a wellness trend, not a medical measurement.
The smart alarm wakes you during a moment of light sleep inside a personal wake-up window, so you start the day feeling more rested instead of jolted awake. Snooze still works in gentle-wake mode. For reliability it uses background audio with a local-notification backup, so keep the ringer on and the phone charged.
Yes. Schlummer records snoring and sleep-talk on device, capturing only the loud moments so you are not storing the whole night. In the morning you can play the clips back, tag a partner in a shared bed, and export a clip as a video with a waveform. Recordings never leave your iPhone.
Yes. Schlummer runs entirely on your iPhone with no account, no cloud, and no third-party trackers, so your sleep data, recordings, and scores never leave the device. Its App Privacy declaration is Data Not Collected, and it is GDPR-friendly because the data is never uploaded in the first place.
Schlummer is free to download. Schlummer Pro is an optional upgrade offered as a monthly subscription at 4.99 EUR per month, a yearly subscription at 29.99 EUR per year with a 3-day free trial, or a one-time Lifetime purchase at 69.99 EUR that is not a subscription. Local prices vary by country.
Schlummer Pro unlocks long-term sleep trends beyond the free morning score, the full library of 12 on-device soundscapes, unlimited snore and sleep-talk recordings, and video sharing of your clips. The free tier keeps the smart alarm, your last-night snore recording, and your sleep score. Schlummer never raises the price on features you already own.
