Any recommendations on a time-saving system to screen tenants would be appreciated.

I use Transunion MySmartMove to screen tenants. https://biggerpockets.mysmartmove.com/

My client screening would be very conservative.Thank you.

@Steve Lundy also note that the 1% rule of thumb, the 8 x gross rent rule of thumb, and the gross rent yield rule if thumb are all doing equivalent math and giving different conflicting screening rules.  

So you buy the buy the property and rehab it, and screen it rent out the other three units based on the ARV and live in the fourth unit.

There is not a mobile app, at least for android; however, I have saved the link to my home screen so I essentially have a Cozy app now.

If you screen well and get a good recommendation from their current landlord, I don't see a big downside here.  

@Gena Kirkwood - I would hope to put myself in the best situation possible by screening tenants well.

At the same time it might be someone who has done their work and might want to partner with you that has a lot to offer you will never know until you go more in detail with the person that messaged you and you screen them.

A common complaint I hear is how they feel like there property is treated as just a number or they didn't properly screen tenants and/or monitor the property and now they have to repair a trashed rental squeezing all the profits they hoped to gain.
