I am loving the three month view as well: it's a much more realistic way of forecasting and planning our family's income and expense. Am looking forward to the calendar: would be amazing if it is similar to the calendarbudget.com calendar.
calendarbudget.com is really good if you want (and have the discipline for) forecasting.
YNAB is really good, but no forecasting (and they explain why).
Prism and Mint are money & biller management type apps that have some budgeting functionality.
This webiste recommends Calendar Budget for people who need bi-weekly budgeting. But it looks like it costs $2.99 a month.
We use CalendarBudget as our main way to track our expenses. It looks very old but functions very well, however lacks detailed reporting. I really wish YNAB had a calendar function because it seems way easier to see balances/transactions coming out in real time. We're struggling to understand and use YNAB, it seems really complicated since my SO and I both deposit into our bill pay account and have separate finances and obligations. What's helped us tremendously is this video and we will continue the good fight towards YNAB!

Don't know if it's a phone app but it's a budget calender that can keep a rolling track of your budget and you can adjust based on your spending so you can plan for the month. I like it because I can map out my bills, how much I have for groceries, and extra expenses based on the dates when the bills are due and when I get paid. Makes life a lot easier to see the bigger picture.
