This has easily been the longest sale we've ever had on Acorn - since March 17th!
But if you've been holding out on buying it for some reason, now is the time to purchase. The 50% off sale will end Monday, August 23rd, and the price will double from $19.99 up to $39.99 USD.
The bundle discount will still be available though. So if you buy multiple copies (or multiple apps), you can save some cash. Or buy now and save even more.
