I add money in with my phone primarily. I can't add in money the same way through the phone app right now because it doesn't show the 2 month, 3 month, 6 month, and goal envelopes. It still only shows monthly and annually. I use the app 97% of the time.
That's a good question. Our plan is to make more Envelope periods viewable on our mobile platforms--we're currently working on our Android app right now, but we don't have a release date yet. We'll be sure to update you when we know, and you can check our Roadmap for updates: https://goodbudget.com/roadmap/
