Value Study Assistant also leads on ads (none vs shown) and update cadence (every 4 days vs every 3 months). Grid #'s advantage is ratings volume (10K vs 1) and iOS requirement (12.0 vs 17.0).

Value Study Assistant holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Grid # has 10K ratings behind it against 1, so its average is the more settled of the two.

Grid # ships an update every 3 months, Value Study Assistant every 4 days. The most recent releases landed on October 14, 2026 and October 1, 2026 respectively.
