Your phone is almost full, and it's mostly videos. Deleting feels wrong, but keeping everything isn't working either. Compression is a better answer — the moments stay, the storage comes back. Now you can batch-compress multiple videos in one flow, so you don’t have to repeat the same steps again and again. You can also still send a video directly from Photos, Files, or another app through the Share menu and continue when you return. Choose a compression option to get started quickly, or set your own target file size for a single video. Not sure about the result? Preview an 8-second sample before committing, then decide whether to continue. Once compressed, preview the result and save it to your Photo Library or Files. If the original was from your Photo Library and the new version is saved, you can delete the original right from the results screen. Everything is processed on your device — no server uploads, no account required.

【Calculate Theoretical Relative Humidity】 A humidity calculation app for managing indoor humidity and checking humidifier performance. Calculate the theoretical indoor relative humidity from the outdoor temperature, outdoor relative humidity, and your indoor temperature. By comparing the calculated value with your hygrometer reading, you can estimate humidification performance and determine when a humidifier filter may need replacement. This app does not measure humidity. 【Key Features】 • Calculate theoretical indoor relative humidity • Compare calculated and measured humidity • Check humidifier performance • Estimate humidifier filter deterioration and replacement timing • Support daily indoor humidity management 【Recommended For】 • Users of evaporative humidifiers • Anyone who wants to check humidifier performance • Anyone who wants to know when to replace a humidifier filter • People managing indoor humidity during dry seasons • Anyone who wants to compare theoretical and measured humidity 【What Is Theoretical Relative Humidity?】 This app calculates the theoretical indoor relative humidity by converting outdoor relative humidity based on the amount of water vapor and applying the indoor temperature. Comparing the theoretical value with your hygrometer reading helps you evaluate humidifier performance and estimate whether the filter has lost efficiency. Ideal for users who want a simple way to monitor indoor humidity and maintain humidifier performance.
