Offline evening setup and morning comfort journal

Stop guessing which pillow setup makes mornings calmer.

Pillow Window helps track evening pillow combinations, pillowcases, support items, room feel and morning comfort notes in one private offline journal.

1

Evening setup

Choose pillows, case, supports, position plan and room feel before sleep.

2

Morning notes

Complete the same record with heat, neck pressure, wake count and comfort.

3

Calm patterns

Compare setups only when enough completed mornings exist.

Two-phase sleep journal

The record begins at night and finishes after wake.

Pillow Window is not a medical app, not a sensor sleep tracker and not a smart alarm. It is a personal observation tool for home sleep setups.

S

Settle

Create Tonight’s setup, carry from last night, note expected issues and keep quick actions close.

F

First Light

Finish open sessions with wake count, heat, neck pressure, face marks, flattening and comfort.

L

Loft

Maintain pillows, cases, supports and saved sets without deleting old sleep history.

P

Pairings

Compare setups, warm-room nights, side-sleep keepers and repeated trouble patterns.

Q

Quiet

Manage defaults, demo data, JSON export, reset actions and app boundaries.

Settle

Tonight’s setup becomes the center of the app.

The user chooses one or two pillows, pillowcase, support items, planned sleep position, room feel, expected issues and optional notes.

Back Side Stomach Mixed Cool Warm Humid
N

New night

Manual setup or preset-based setup, with preview before saving and validation when no pillow is selected.

C

Carry from last night

Copies the previous setup but asks the user to review position, room feel, supports and expected issues.

A

No duplicate today

If today’s evening record already exists, the app edits that session rather than creating a duplicate.

Loft library

Pillows, cases, supports and sets stay organized.

The library is lightweight and domestic: real pillows, pillowcases, rolled towels, side supports and saved setups.

P

Pillows

Track fill type, height level, firmness, size, notes, completed nights and average comfort when enough data exists.

C

Cases

Keep material, cooling feel, closure type, notes and use count for pillowcases.

S

Supports and sets

Save knee supports, neck rolls, side supports and repeatable setup presets for future nights.

1

Set against set

Compare two presets or two completed sessions across composition, wake count, heat, pressure and comfort.

2

Warm-night winners

Only appears when warm or humid room observations have enough completed alternatives.

3

Side-sleep keepers

Compares side-sleep setups without inventing rankings from too little history.

4

Trouble repeats

Groups repeated complaints by pillow, case, sleep position and room feel only when observations are sufficient.

Pairings

Comparison without fake certainty.

The app shows messages like “Complete two more warm-room nights to compare setups” instead of making artificial conclusions from incomplete data.

Quiet and local data

A fully offline iOS utility with clear boundaries.

Pillow Window uses SwiftUI, UserDefaults and Codable. It avoids internet, accounts, cloud sync, HealthKit, AI, external APIs, sensor sleep tracking and push notification pressure.
