Recreational / Hobbyist UAS pilot reported being unaware of a TFR and flying within it without authorization.

Narrative

This was a spontaneous decision to video an update on the road construction that I had been videoing occasionally for several months. At my usual staging spot at that location and while doing preflight checks; I discovered that I had not uploaded my regular drone flight planning software to my new phone and did not have my iPad with me of which I would have if this had been a planned flight.However since I had flown there for this type of mission recently and a few times there before; I decided to trust my drones app to advise me of any airspace problems; which showed none. In addition with ADS-B I knew I would be advised by the App if there were any manned aircraft in the area.I decided that the limited altitude that I would by flying at (150 ft.) that I was certain of safety and had a short uneventful photo shoot flight.Upon returning home I installed and updated my drone flight app on my new phone and was surprised and upset to discover that a TFR had been issued for XA00pm UTC that day because of firefighting operations. No firefighting operations were underway in our vicinity; and my flight was barely within the boundary of the TFR; along with my entire town.In conclusion; I believe that my flight was completely safe however if TFR's are now so liberally issued; my lesson is now to always confirm NOTAMS for drone flying even if I recently have flown at the same location recently and not to trust my drones App as being timely in their automatic airspace and warning information.
