Hi Jacee,

no there currently is not.

Currently sending using priority will build a 90 satoshi/byte transaction, which when compared to the fees recommended is on the upper bound of the bracket.

Assuming you build a standard transaction the fee should more then enough to be included with the next block,
please see our article below, which goes into details how the fee is chosen, how transactions are affected by the fee and how you can estimate the confirmation time for a transaction.

TL;DR:
Android:
If your wallet is up to date it will display the fee paid per byte at the bottom of the transaction details, which can be entered by selecting the Transaction within the Transactions-tab an choosing "Show Details" from the dropdown menu.
You can then check https://bitcoinfees.21.co to see what the current recommended fee is for a transaction to be included in the next block beneath the graphic in bold.

iOS:
Our iOS version does display the fee used broken down to sat/B, you can also go into the transaction details and copy the transaction id by long-pressing the transaction id and search for it, check your transaction id using https://www.smartbit.com.au, it will display the fee used in sat/B, which can also be compared to what https://bitcoinfees.21.co recommends.

ViaBTC is a mining group that will priotize your transaction if you have given it a fee of 0.0001 BTC or higher, you can provide them with your transaction id here https://www.viabtc.com/tools/txaccelerator/

Hope this helps
