Thanks for the update. I'm using SmallFish instead of Stockfish app nowadays
New SmallFish update

If you have a few dollars to spare, you should buy my MegaDatabase, Encylopedia and Tablebase etc. www.smallchess.com
There will be lots of updates throughout the year, and new apps.
Hi,
I'm the developer for the SmallFish app. It's a free iOS app that allows you to play against a strong engine. There's a new update for iPhone 6/7 and multi-line analysis (see below). It's a totally free app.
The app is able to play very strong chess.
