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.

Verdict
The clearest difference is review sentiment: Zen Battery at 89% against Draw's 26%. Zen Battery also leads on rating (4.7 vs 2.2) and ratings volume (8.1K vs 5). Draw's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 6 weeks vs every 18 months). On price, ads, in-app purchases and device support there is nothing between them.

Draw ships an update every 6 weeks, Zen Battery every 18 months. The most recent releases landed on October 4, 2026 and October 14, 2026 respectively.
