Editing and refining graphs

Any sleep record can be adjusted after the tracking ends. Whether you forgot to stop the app, woke up in the middle of the night without the app noticing, or simply want to add a note about your caffeine intake, you can fine-tune your data here.

To enter Edit Mode, tap the pencil the pencil ic pencil icon on any sleep graph.

1. Quick Adjustments: Ratings, Tags, and Comments

1.1. Rating your sleep

On the morning screen, tap the stars to rate your sleep quality.

  • 0 stars: Bad sleep.

  • 5 stars: Amazing sleep.

Note If you leave the stars untouched, the sleep won’t be factored into your long-term "Sleep Quality" statistics. If you manually set it to 0, it counts as a zero-rating.

2.1. Trimming the graph

  1. Open the edit mode: From the Morning screen, tap the pencil ic pencil icon to open the edit mode.

  2. Select an Area: Drag your finger across the section of the graph you want to modify.

  3. Refine: The section will zoom in. Use the handles to adjust the start/end times precisely. You can also manually type the times in the top bar.

  4. Apply the Cut: Tap the scissors icon (✂️) in the top right.

What happens next depends on where you cut:

  • Trimming the edges: If your selection touches the very beginning or the very end of the graph, that time is deleted (the graph becomes shorter).

  • Splitting the middle: If you select a section in the middle of your sleep, that section is converted into an Awake period. The time is subtracted from your sleep duration.

Tip Made a mistake? Tap the Menu (⁝) button and select Undo. You can revert up to 5 previous changes.

2.2. Editing awakes

  1. Open the edit mode: From the Morning screen, tap the pencil ic pencil icon to open the edit mode.

  2. Select an Area: Drag your finger across the section of the graph you want to modify.

  3. Refine: The section will zoom in. Use the handles to adjust the start/end times precisely. You can also manually type the times in the top bar.

  4. Revert or remove the awake: Tap the open eye icon in the top right, and either choose add awake or delete awake.

Note Deleting awakes won’t work for paused tracking (there is no sensor data from that period) and for the awakes manually entered by the user.

3. Troubleshooting

3.1. Red Blocks (Data Gaps)

Seeing Red Blocks? This is the #1 concern for new users. Red blocks do NOT mean a health emergency. They simply mean the app lost sensor data.

👉How to fix it

Try turning off Battery Optimization for our app. Check out dontkillmyapp.com for a quick guide on how to do this for your specific phone model.
If you are using a wearable, disable the battery optimizations also for all involved apps, including the Bluetooth app. Also, check if the watch does not go into ‘sleep’ mode.

3.2. Flat Noise graph

If your noise graph appears as a completely flat line without any fluctuations, it typically indicates that the app lost access to the microphone during the night.

👉 How to Fix It:

Check Device-Specific Settings: Manufacturers often have aggressive background limits. Visit DontKillMyApp.com for a step-by-step guide tailored to your specific phone model. System-wide features like Adaptive Battery can put the microphone to sleep to save power.
Avoid Microphone Conflicts: Most operating systems allow only one app to access the microphone at a time. Make sure other apps that perform sound analysis (like voice recorders or smart assistants) are closed before you start tracking.

3.3. Too many or too few awakes detected

Awake detection is a little tricky for actigraphy method. The app monitors light, sound, movement, heart rate, and phone activity to determine when you’re awake. Since every bedroom environment is different, the default sensitivity might need a little fine-tuning.

👉How to fix it

Adjust Detection Sensitivity:

  1. Go to Settings → Sleep Tracking → Awake Detection.

  2. Adjust the sensitivity sliders for individual triggers (like movement or sound) to better match your environment.

Add or Remove Awakes Manually:

If the app recorded an awake period that didn’t happen (or missed one), you can fix it post-sleep:

  1. Tap on your sleep graph to enter Edit Mode.

  2. Follow our guide for editing the awakes to remove or add specific periods from already finished graph.

3.4. Morning screen shows too much

If the screen feels cluttered, you can simplify your view to focus only on the data that matters most to you.

👉How to fix it
Remove Cards: Simply swipe a card away to hide it from your feed.
Toggle Visibility: Tap the Hide/Show button at the bottom of the screen to manage multiple cards at once.
Pin to Top: Long-press any card to pin it to the top of your list for quick access.

3.5. The graph is too long

If your tracking ran too long, you can easily trim the beginning or end of the graph to correct your sleep duration.

👉How to fix it

  1. Enter Edit Mode: Tap directly on the sleep graph card you wish to adjust.

  2. Select the Overlap: Drag your finger across the section of the graph you want to remove (the "extra" time at the start or end).

  3. Cut the Data: Tap the Scissors icon (✂️) in the top-right corner to delete the selected period.

Tip Mistakes happen! If you accidentally cut too much, you can revert your changes. Tap the Menu (⁝) button and select Undo. You can go back up to 5 steps.

3.6. Missing sleep period

The Edit Mode can only remove or reclassify time. If you forgot to start tracking entirely and want to add a new block of sleep:

  1. Go to the Left ≡ menu → Graphs or Left menu ≡ → Stats screen.

  2. Tap the plus icon :plus (Add sleep).

  3. Manually enter the start and end times.
