crab,

They were screenshots, stored when the aircraft was approaching Welshpool.

Figure 13 to 15 show the stored screenshots for the relevant apps.
Both of the screenshots for RunwayHD (Figure 13) and SkyDemon (Figure 14) show the position of the helicopter as 8 nm east of Welshpool Airport (33 nm from the accident site, at 2,280 ft amsl with 112 kt groundspeed), implying that SkyDemon had been selected prior to this point (no information available as to how long for) and that RunwayHD was then selected and remained selected until the accident5.
