FYI man, after comparing it to Photoshop, check that the fonts generated using the app come out looking thinner, check this screenshot:

The first one is the one exported from the app using AA high, the other 4 are from Photoshop.
Notice the thing in the middle of the A (let's call it the bridge), it is thinner compared to all the others (except in crisp).
also, notice that the bridge occupies 2 pixels in the ones using Photoshop,
but, more importantly, the slants of the A are much thinner in the one from the exported PNG, compared to the ones from Photshop.
