Sleep Tracker, AutoSleep vs Battery Materials Toolkit

SleepTracker is a simple and intuitive app designed to help you track your sleep patterns and improve your sleep quality. With SleepTracker, you can effortlessly record your sleep start and wake-up times, along with the number of awakenings during the night and the total sleep duration. On the homepage, you’ll find the most recent sleep record displayed, including your last sleep and wake-up times. Simply tap the “Add Record” button to log your sleep by inputting your sleep start time, wake-up time, and the number of times you woke up during the night. SleepTracker calculates and stores all your sleep data locally, ensuring your privacy. With a clean, user-friendly design, the app also provides a “History” section where you can view your past sleep records, including the sleep times, duration, and date. You can delete any record with a simple swipe. A privacy disclaimer is available in the top-right corner, explaining that no data is collected beyond local storage, and reference links are included for further transparency. SleepTracker is perfect for anyone looking to track their sleep habits and make improvements for a better night’s rest.

Battery Materials Toolkit is a focused calculator toolbox for battery materials and electrode work. It helps you move from quick lab estimates to repeatable calculation snapshots without spreadsheets or sign-in. Included in v1.0: - Theoretical capacity in mAh/g - Energy density in Wh/kg and mWh/g - N/P ratio with balance hints - C-rate, current, and charge/discharge time - Current density in mA/cm² - Areal capacity, mass loading, active material ratio, and specific capacity conversions - Electrode recipe mass calculation for active material, conductive additive, binder, and solvent - Unit converter for common battery-material units - Local saved calculations with notes, reopen, and delete All calculations run locally on your device. Saved calculations stay on this device unless you choose to share the results yourself. This app is intended as an engineering and research aid. Please verify important results with your own protocols and standards.
