Savings Account Apps?

I have been using The Ally banking/savings app for a few months and have been quite happy.  I have a checking and a savings account.  The savings account currently earns 2.2% and has gone up twice since opening the account.  I use the checking account to save for known upcoming expenses and the savings I am using for emergency fund.  Also, there are no fees. 

OMG I JUST FOUND THIS!!

4.00% APY under $3000 and the following requirments

• Have tmobile wireless account
• deposit $200/month
• sign up for tmobile perks

Now with these stipulations you can max. your money. See the secenarios below.

T-Mobile Money states you will make 4.00 APY if you have the fall in line within the 3 listing eligibities above. If you go over the $3,000. this means that the $3,000 will make anywhere between 2.79-4% APY and anything after the $3,000 will only make 1% APY.

So you put $2700 in the account, set up $200 deposits per month (which will bring it up to $2900, for the 4% APY). then you can set up a $200 withdrawal every month. this will keep it under the $3,000 threshold guanretee you the 4%.
