Matt,
(I got my Duster 1.5dCi 4WD w/ the service reminder disabled. I recently enabled it to see if the mentioned Apps work & both work. Personally I don't need it as I have a dedicated all brand scanner w/ about 30 service functions).
U said u have a WiFi OBD adapter & u mentioned Car Scanner & Dacia service reset apps. Have u been able to make a connection to the computer (IGN on) w/ the Car Scanner app & does it display your vehicle parameters as a table or dashboard? U wanted to use the latter App.
I have 5 adapters incl 2 of the latest Konnwei BT ver 5.0. If nothing is mentioned on the Konnwei it is BT 3.0.
I have used the Konnwei 902 BT 5.0 for this job. The required 'PIC18F25K80 chip' can be seen in the dismantled adapter. I tried the top left BT adapter also & it works. Don't ever buy or use the blue one seen on top right, which may also be white. The one below that is a WiFi unit.
As u wanted to use the Dacia service reset app (ver 0.50 @ time of writing):-
* 2 pics of the App in Play Store & Open App in my phone.

Keep DATA on > After 'CONNECT' & on exiting the App there will be a full screen ad.
Focus on top right. 'Skip Video' will appear after 5 secs > Press Skip > then the close (X) mark will appear on top rt > press that. After connecting > Reset > all dash lights will flash & the interval will be reset. Exit.
The service interval is 10k km in India. Just for documentation I have reset it from 9900 to 10k km. I took these pics @ an angle due to the glare.
