Comments on 3-Level for Android

★★★★★ Now for Android! This excellent app is valuable for Air Force aircraft maintainers since it combines all the common times, dates, and frequently needed info right into your phone. Already a hit on the iPhone, now it is available on Android.

★★★★★ This is DOPE for maintainers! Zulu times are extremely helpful for annotating times in the forms! Suggestion for a future update. If possible to be able to add fuel conversions from gallons to pounds when we can't read POL's handwriting on the fuel receipt 😂

★★★★★ Insp c/w Makes figuring out if you got to do a PR/BPO insp with ease!

★★☆☆☆ As previously stated, please update android's platform to have the same options as apple. I'd love to have the base list option.

★★☆☆☆ Updates not supported on Android devices, Apple devices work though.
