Sleep Cycle Alternative Without a Phone on Your Bed (2026)
Dovy Paukstys
Founder, Komori Care
Phone sleep apps turn the phone you already own into a microphone or a motion sensor. That works. It also means a lit slab on the mattress or the nightstand. If you want the phone out of the bed, you need hardware.
Disclosure: I am Dovy, founder of Komori Care. We are building a contactless bedside sleep monitor, coming 2027, wellness only.
Quick answer
- Phone apps such as Sleep Cycle, SleepTrace and OpenSleep use the phone's microphone or motion sensor. SleepTrace says it is free to start, with Premium from €6.99 a month as listed on sleeptrace.app in October 2026. OpenSleep is free for tracking, open source and on-device, with no account.
- Phone away from the mattress: Hatch Sleep Clock (nightstand radio sensor, no wearable, no camera, no mic), wove (wove's FAQ says low-power radar and a microphone from the nightstand), or OZI under the sheet.
- Komori Care (coming 2027, wellness only): bedside 60GHz radar with no camera, designed to keep tracking without a phone in the room and to show a back/side/stomach position timeline.
If Hatch is the clock you are comparing, see Hatch Sleep Clock alternatives.

What Sleep Cycle actually asks you to do
Sleep Cycle's phone placement help describes two modes: microphone or accelerometer. Accelerometer mode analyzes movement and warns you not to put the phone under a pillow or thick mattress. A second Sleep Cycle article, why the microphone is recommended, says you do not have to keep the phone in bed and can place it on a nightstand.
So the honest answer is: it depends on the mode. Microphone mode can sit on the nightstand. Accelerometer mode wants the phone in the bed.
Hardware that is not your phone
Hatch Sleep Clock. Nightstand. Hatch says no wearable, no camera, no mic. Sleep tracking included, no subscription required, per Hatch. $249.99 as listed on hatch.co in October 2026. You still use the Hatch app for insights.
Sleepal AI Lamp. 60GHz radar lamp. $399 in Tom's Guide. Basic tracking free. Still pairs with an app.
wove. The site says a bedside device tracks sleep without a wearable, using radar and a microphone, then can adjust room climate. Core plan is included with purchase, per wove's FAQ.
OZI. $199 under the sheet. Connects to its app over Bluetooth. No camera or mic. The phone is for the dashboard, not the sensor.
Free apps, with the tradeoff
OpenSleep: on-device, no account, phone on the nightstand or the mattress. SleepTrace: on-device audio, phone on the nightstand, free tier, Premium from €6.99 a month. Stages are estimates. See sleep tracker accuracy claims and phone data and sleep.
Komori Care (coming 2027)
Komori Care keeps your phone off the mattress by design: 60GHz radar above or beside the bed, no camera required, and a planned back, side and stomach timeline. It is designed to keep tracking without a phone in the room. It is coming in 2027, wellness only.
FAQ
Does Sleep Cycle need the phone on the bed? Not in every mode. Sleep Cycle's placement page has an accelerometer mode that uses the phone in the bed. The microphone help page says you can put the phone on a nightstand.
Are phone sleep apps accurate? Stages are estimates. See sleep tracker accuracy claims and phone data and sleep.
Is there a no-phone, no-wearable tracker? Hatch, Sleepal and OZI. They still pair with an app for setup or the morning graph.
Is a free app enough? Depends. Free apps cover bedtime and rough timing. OpenSleep and SleepTrace's free tier are the honest starting points.
Does Komori Care need my phone? Komori Care (coming 2027, wellness only) is designed to keep tracking without a phone in the room.
