If you're willing to do a little work using Excel, you can build yourself an investment tracking spread sheet. Mine has no fancy pants links or any of that crap, just places for me to update balances, a total of everything, ER column and expense column (seeing the actual number is a good thing to have) with a total expenses box.
At the bottom, I set up a total of US stock funds, US bond funds, International stock funds. (asset allocation).
Ok, so why do you need that? Well, instead of a target date fund, you can buy the lower cost index funds separately and fine tune your AA as you want it. Rebalance once a year on your birthday. The other nice thing with this is that you can have as many accounts as you want and optimize what's in each from a cost perspective. You could have VTi at TDAmeritrade, VTSAX at Vanguard and SCHB at Schwab which are all like total US stock. Never try to put every type of fund in every account. You don't need to do that. In my case, my rollover IRA is half my portfolio and where I do my rebalance work. So I can go all US equity in taxable and Roth and keep all the bonds in the IRA.
Know the ER and choose by lowest ER. Sure, you could choose VTI at 0.05% at TDA instead of SCHB at 0.03% because you like the way Vanguard does their management and because the ER changes at the end of the year to cover the previous year....which is usually lower. But don't go picking some 1.13% fund!
