Apercu is a realist-influenced geometric sans-serif typeface released by Colophon in 2010. Colophon is an independent type foundry set up by UK-based studio The Entente. Apercu is currently one of my favorite fonts — it’s full of character and is easily distinguishable from other sans-serifs out there. Apercu Mono is Apercu’s monospaced counterpart.
If you are looking for an alternative to Apercu, I personally recommend checking out Circular and Larsseit. I think Freight Text would make a nice font combination with Apercu.
