Narrative:

I filed and flew two VFR out and back legs. I planned the flight on my ipad using garmin pro pilot; but filed using [a flight planning website]. I had just landed at my home airport and was putting the aircraft in the hangar when a car drove up and the driver asked if I had a VFR flight plan. I replied in the affirmative; and stated that I had just landed and was about to close it. The driver said that the FSS had called the airport and was looking for me. I immediately closed the flight plan; but I was puzzled as to why this had occurred. Upon arrival back home; I looked at the filing. The online software automatically populates the speeds for aircraft type; while the pilot enters the other data. The software [I] had used the correct airspeed for the first leg; but then used an airspeed 25 KTS faster for the second leg. Because I was using the ipad enroute; I didn't catch the discrepancy. I am going to be much more cautious about automatic online filing; and review each item more closely. It is my fault that this occurred. The FSS was right to check on me; and I'm grateful they did.
