Help Helium

[zuben el genub]

I've got it, and have backed up the Oppo. But I've never had to reinstall anything since I hadn't factory reset nor rooted the phone.

How can you double check exactly what is backed up and will reinstall from the saved files?

I bought most of the Green Mountain Digital Audubon guides. Once from Google, and once from Amazon.
(Google said the Oppo couldn't use the apps, so I repurchased for 99 cents each from Amazon and they run just fine on the Oppo.

I don't want the new updated versions. Audubon has taken more of a lead, and wants everyone on the forums and socializing. I've been a member of a couple of local Audubon societies and the propaganda, other nonsense and demanding extra money got to be a real drag. Nothing about helping the local wild life. Green Mountain makes Keurig, and you know what happened when Keurig installed DRM in the coffee serve cups.

I have not updated any of the apps to the new versions. All they added was social junk, not new birds.
If I back all these up with Helium, how can I make sure that all of the bits and pieces for the old apps to run are there? Check file size?

Thinking about a new phone (TMo and changing bands) - how will this transfer to another phone from Helium?

Thanks
