For what it's worth, the best Sheepshead app I have found – Sheepshead Pro Review

Been playing SH for three decades plus, and this app is a solid effort. That being said, it could use some improvements. 1. The odds of three 4Q finesse hands in a game of nine hands (3 player mode) are astronomically low, but the computer seems to manage it often enough while I get the 4Q monster hand once every 6-10 nine-hand games, which seems much more reasonable. Cost: one star Please fix the algorithm, it is skewed. 2. When partnered against a picker, the "schmear" tactic can effectively crack the picker. The computer partner will dump the 7d for zero points when I have already claimed one trick, then it will hand over the 10d or Ad when the computer picker has claimed the trick. Cost: one star Please fix the AI for the partner, unless you want to list it in he description as irretrievably stupid. When it's not frustrating my efforts to win by either of the two points above, this program is among the best I have seen, and I have helped programmers fix issues like this in the past.
