How can we help?

The guided iOS automation can relaunch Sleepy Banana when an unresolved alarm needs attention. You can also enable an iOS Fallback Alarm and choose its intervention delay for each alarm. The system fallback can ring while the app is closed; its Stop button does not require your wake-up challenge. Check both options in the app’s alarm settings.

The intervention delay starts after the expected ring time, not when you create the alarm. If you snooze for ten minutes, the fallback is rescheduled after the snoozed ring time plus that alarm’s chosen delay. You can enable or disable the fallback and set a delay from 0 to 60 minutes for each alarm; zero means no added delay.

Mattress mode estimates Awake, Light and Deep from movement and does not infer REM. Nightstand mode can estimate REM from a qualified respiratory signal, and compatible Apple Watch sleep data can also include REM. Unreliable or missing stages are left unavailable.

Start, pause or end sleep tracking and set an alarm on your iPhone. You can snooze or stop eligible alarms from the Watch; alarms requiring a wake-up challenge must be completed on the iPhone. Available Watch stages and vitals can be synced into your sleep history, and an optional wrist-alarm fallback is available in Watch settings.

Yes. Layer soundscapes, save your favourite blends and choose 10, 30, 60 or 90 minutes of playback, or all night. The soundscape Live Activity includes Lock Screen controls for playback.

Yes, after the initial setup downloads. The language model is about 1 GB, and natural voice adds a one-time 325 MB download. Once installed, Nana’s text and voice conversations run locally on your iPhone without an internet connection.

Your Nana conversations remain on your device. They are not sent to a remote AI service or included in analytics.

No. Snoring and sleep recordings stay private and are not shared or uploaded for analytics. You control what remains saved on your phone.

A result may be unavailable when the app does not have enough reliable sensor data. Sleepy Banana avoids presenting low-confidence measurements as definitive results.

While sleep tracking is running, Smart Wake looks for lighter sleep within the window you set, before your scheduled wake time. With Smart Wake off, the app targets the time you set. If enabled, the iOS fallback is scheduled after the expected ring time using your chosen intervention delay.

No. Sleepy Banana supports sleep awareness and routines, but it is not a medical device and does not diagnose, treat, or replace professional medical care.

Use the privacy and data controls inside the app. You can also review the Privacy Policy below for details about data handling and your rights.

Choose On Mattress or On Nightstand to match your phone’s position; placement is not selected automatically. Keep the phone connected to power, allow the requested permissions and start tracking before bed. Nightstand mode checks the reflected signal before tracking; follow its setup guidance.

Yes. Replay a saved clip and label the sound you hear, such as snoring, coughing or talking. You can apply a label to similar recordings and verify those inferred labels later. The current app labels sounds; it does not identify which person made them.

Sleepy Banana listens for relevant sleep sounds and organizes detected moments into clips, so you can review useful events instead of searching through hours of audio.

Yes. Once tracking is started and the required permissions are enabled, it is designed to continue with the screen locked. Keep your phone powered through the night.

Choose maths, shaking, typing, a maze, sheep, face matching or QR; NFC tag scanning adds an eighth option on supported iPhones. Register a QR code or NFC tag before using it. An emergency stop becomes available after repeated failures or 90 seconds. The separate iOS fallback’s Stop button bypasses the challenge.

Yes. Set the nightly target that fits you, then use recent averages, goal gaps, and success trends to understand how consistently you are reaching it.

The score brings together duration, continuity, regularity, timing, morning alertness, and your restorative-sleep rating to give each night useful context.

No. Nana conversations and sleep recordings stay on your device. They are not sent to a remote AI service, shared, or included in analytics.
