Undertale controls

So after just a few years I needed to play Undertale on my cellphone once more. Everybody appears to play this new model with built-in controls, the issue is that after spending dozens of hours on this recreation on my cellphone years in the past, the analog stick design is horrible. I bear in mind having a gamepad app (second picture) that will let me swap the keyboard with the gamepad proven and it was very snug, the motion controls have been simply 8 buttons as an alternative of an analog. Does anybody know what this gamepad app identify was? I can't discover it on play retailer
