CatNapp is an app made with love. You can select the minutes your'd like to sleep, select your favourite noise and fall asleep. The alarm sounds are gentle and sweet...like our little cat! - Sleep for up to 120 minutes - Fall asleep listenining to gentle noises (birds, rain, the ocean, meditation sounds, etc.) - Try to catch the cat winking at you when opening the app - Wake up to a sweet alarm sound. --------WHAT IS A CAT NAP?-------- A cat nap refers to a short and light sleep, typically taken during the day. It is named after cats because they are known for their ability to take quick naps throughout the day. A cat nap is usually brief, lasting anywhere from a few minutes to around 20 minutes, although the exact duration can vary from person to person. The purpose of a cat nap is to provide a short period of rest and rejuvenation without entering into deep sleep or experiencing sleep inertia, which is the groggy feeling that can occur upon waking from a longer sleep. Cat naps are often used to combat drowsiness, increase alertness, and boost productivity. They can help alleviate fatigue, improve cognitive function, and enhance mood. Taking a cat nap can be particularly beneficial for individuals who may not have had sufficient sleep the previous night or are feeling tired during the day. However, it's important to note that cat naps are not a substitute for a full night's sleep and should not replace regular, quality sleep. CatNapp helps you take those quick power naps while listening to a gentle white noise and it wakes you up with beautiful sounds, from a forest to babies laughing.

Vasten does one job well: it keeps an accurate record of your fast. Start in one tap, see elapsed time and your goal on the main screen, and keep the timer visible through a Home Screen widget, Lock Screen Live Activity, and Dynamic Island. Reaching the goal never ends the fast automatically—you decide when it ends. Your history remains useful and under your control. Correct start and end times, review simple totals, import Vasten JSON or Zero history, export everything as JSON or CSV, or delete any record. Features: • One-tap start with an adjustable start time • Custom fasting goals from 1 to 168 hours • Clear widget goal progress and goal end times • Lock Screen and Dynamic Island Live Activity • Small and medium Home Screen widgets • Separate timer and 12-week fasting-activity widgets • Custom accent colors shared across the app and widgets • Editable history and summary statistics • Configurable local goal-time notification • Vasten JSON and Zero fasting-history import • Private device storage with private iCloud synchronization • JSON and CSV export • English and Dutch • No account, ads, analytics, or subscription Stage labels are general educational time ranges.
