Here you have the definitive battery application for your iPhone and iPad from Shinobit! A quick glance will let you know how many hours you have left for listening to music, watching videos, talking on the phone and surfing the Internet. If you want your battery to be even more "Zen", touching the screen once will hide the icons, leaving only the time and the battery charge percentage on the screen. Touching the screen a second time will only leave the battery. Touching a third time brings back all the data you had at the start. Move the device to see how the fluid moves around inside the battery, tilt it and you will see how it moves from one side to the other. You can change the color of the liquid inside the battery and the battery design that best suits your personality. Once the battery is charged, the application will make a warning sound.

"The only thing you need to remember, disappears neatly in 3 taps." Samsepan is a minimalist Lock Screen sticky note app that strips away all complex features and focuses entirely on 'simplicity'. A sudden idea, a verification code you need just for a moment, or a carton of milk to buy today. Don't bother opening an app to delete these highly volatile, temporary notes. Pin your note directly to the Lock Screen (Live Activity). When you're done, simply tap the widget. Tap exactly 3 times (The Rule of 3), and it vanishes from your screen instantly and conveniently. [Core Features] Instant Volatile Memo: Delete immediately from the Lock Screen with 3 taps, no app launch required. Minimalist Design: Intuitive, clutter-free yellow sticky note UI. Always in Sight: Pin notes instantly to the Dynamic Island and Lock Screen. [Pro Version Perks] Pin multiple notes at once (Up to 4 multi-posts). 4 vibrant theme colors to suit your taste. Accidentally deleted? Recover up to 10 recent notes from History. Pin it simply, delete it without hesitation.
