Part 107 UAS pilot reported they learned during post-flight they inadvertently flew in a TFR without authorization.

Narrative

I wish to report an accidental violation of a TFR. I am a Part 107 Commercial Pilot working for Company X. We had an event near ZZZ over this past weekend. I checked AirMap (the app I use regularly to check airspace and have never had cause to question) for a TFR the morning of Day 0 before leaving the house and again when I arrived at the scene. There was no TFR indicated so I flew; keeping a reasonable distance and altitude as to not disturb and/or distract the working crews. I was operating from the edge of the event; plainly visible and wore a bright safety vest identifying myself as a UAS pilot. No one looked at me twice. I was in the air for about 11 minutes.Day 1 while talking to another pilot; he mentioned a TFR being in effect until XA:30; I was surprised and immediately pulled out my phone to checked AirMap again; it still showed as being unrestricted. I then opened a second app; Aloft and there it was. I cannot begin to describe how upset I am with myself. I had thought due diligence was done but I was wrong. Moving forward I will no longer trust commercial apps; I will be going to TFR.FAA.gov exclusively to ensure I have the most up to date information.Please let me know if I can provide any further information. I have taken screen shots of each app; but fully understand that AirMap is not to blame here; the mistake was my own; and it will not happen again.
