Both will call your providers to get you a lower bill. Billshark charges a share of what it saves you and nothing if it fails. Sparrow charges a flat membership that also covers class action claims and other refunds.
The short version: Billshark is a specialist: its negotiators work on internet, wireless, TV, satellite radio and home security bills, and you pay only when they save you money. If lowering bills is all you want, that pay-on-success model is hard to argue with. Sparrow is a broader membership: bill calls are included alongside class action claims, unclaimed money search, subscription cancellation and late delivery refunds, for a flat yearly price instead of a cut of your savings.

Billshark is a good product. Here is what it does better, and what Sparrow does that it does not.
No subscription and nothing up front. When Billshark lowers a bill it charges a one-time fee of 40% of the savings it secured, and nothing if it finds no savings; where offered, you can split the invoice into 2 or 6 payments. Each successful subscription cancellation has a flat fee, shown before you confirm ($9 on its App Store listing; its terms say $5). Insurance rate checks are free.
One membership at $3 to $7 a month, billed annually, priced by what your claims are worth. It covers class action claims, unclaimed money search, bill negotiation calls, subscription cancellation calls and late delivery refunds. If you do not earn more than you paid, Sparrow refunds the difference.
What Billshark and Sparrow each do, and what they cost.
A one-time fee of 40% of the savings it gets you, charged only if it lowers your bill. Billshark measures savings as the difference between your old and new rate over the savings period, counted for up to 24 months. Each successful subscription cancellation has a flat fee, shown before you confirm.
The App Store lists the seller as The Bill Reduction Company. Billshark’s website says it is powered by ApexEdge and backed by Mark Cuban.
It depends on how much you save. Billshark costs nothing if it fails and 40% of the savings if it succeeds. Sparrow is a flat $3 to $7 a month, billed annually, whatever the calls save, and refunds the difference if you do not earn more than you paid. For one small saving, or a call that fails, Billshark can be cheaper; for larger savings Sparrow’s flat price can work out lower. Sparrow’s calls cover internet, phone and utility bills, so check that your bill is one it handles.
No. Billshark lowers bills and cancels subscriptions. It does not find or file class action settlement claims or search unclaimed property, which are the core of Sparrow.
Yes, and it is free. Calling your provider, asking for retention and mentioning a competitor’s price often works. Both Billshark and Sparrow sell the time and the hold music you skip.
