I've seen a credit score increase of 100 points in the past 3 months or so
I use chime credit builder card and I also use self and the extra debit card. They all help build your credit though. I use my credit builder card almost everyday at work to buy food or energy drinks like redbull. I drink like 3 redbulls a day at work. I be using that shit a lot cuz having good credit is important I'm almost at 650 and I started off at low 500s
