I agree with
@grovesy - App and reader should be the same as far as I am aware.
I know you have said you've started using recently, but is there a chance your reader is still using the older algorithm? That’s the only reason I can think why they may be different unless you are timing scans just either side of the sensor datapoints?
Reader was delivered approx. 8 weeks ago, phone is a Galaxy A50, so quite recent as well (not that should affect the actual app being used, which I downloaded again approx. 8 weeks ago.
Been using Libre now for 4 weeks today, following an online intro session (because the original one at the hospital was cancelled in March, and currently not doing the physical ones). So, 6 months later than originally planned to start it - but got there in the end

If the two scans were either side of the sensor data points, I would expect possibly a small variation (if the trend was in top gear either direction), but not if both are showing flat. Also, with the number of double-scans, the liklihood of them all being split over the few seconds between them is highly unlikely.
The current sensor does seem to be a bit more stable in that respect, and sometimes the reader is even below the app, or the same, but mostly still reading higher. Examples the last few days, (app then reader, trend both flat unless mentioned) 5.8 and 6.2. 8.3 and 8.7. 7.7 and 7.8. 8.9, 8.8. 8.4, 8.9. 7.1, 7.2. 8.7, 9.2. 4.8, 5.4.
Given that it is the sensor which holds the data, and both devices are reading the same data, something somewhere appears to be out of synch.
I'm currently building a spreadsheet with the comparative levels, to highlight especially when they are significantly different. Also, seeing the differences, my attention to detail from back in my work days gets my curiosity going, as to where the differences are coming from! (Used to dig through and pick out loads of little details, to get the differences in area measurements down to zero, or where the sums were going astray on the budget side ... sense of triumph when I found those obscure little details LOL.)
And now, bother! I thought I had got past the post-lunch spike in range, but no ... 11.1/11.4 LOL. Do I adjust the bolus, or watch and wait? Decisions, decisions ... OK, another 2 units
