D&D Beyond has finally released a mobile app, so you can check the character sheets you have in their system offline.

At the time of writing, the free download is #13 in Apple’s Entertainment section and doing well with 4.4/5 review starts. You can download it here.
The Android app is doing a little less well, scoring 3.6/5 on Google Play. The 1/5 reviews received there are from D&D players frustrated the app doesn’t do more, with a minority having technical issues with the app.
The app has no dice rolling functionality, but you can track hit points, spell slots, conditions and features.
