Yes, @taniak, if you wish your respondents to fill up the form through the Collect Android App they will need to download the app (KoboCollect or ODK Collect) from the Play Store and then configure the same as outlined in this support article shared in the community previously:
Kindly please note that the article also has a section where you can configure (a lot of apps simultaneously) through the help of QR.
Once you configure the app, and press the Download form, you should get all the deployed forms to the app. The respondents should then be able to select the appropriate forms to fill up. Maybe you could also try out BlueStacks as outlined in this previous post:
I would say the respondents should be well aware of using KoboToolbox for this. Otherwise, a short training should also help them collect data for relevant forms as needed.
But yes, if you feel like it’s a risk, maybe collecting data through Enketo is the best option as it should work both with IOS as well as Android devices. Besides, no training for the respondents is required too.
