# Brainly vs UDI APP

The clearest difference is in-app purchases: UDI APP at none against Brainly's 10. UDI APP also leads on ads (none vs shown) and iOS requirement (13.0 vs 18.0). Brainly's advantage is update cadence (weekly vs every 11 months) and chart position (#94 vs unranked). On price and device support there is nothing between them.

Both are free to download. Brainly sells 8 in-app purchases, starting at $2.00 per month. UDI APP asks for nothing beyond the download.

Brainly ships an update weekly, UDI APP every 11 months. The most recent releases landed on November 12, 2026 and November 11, 2026 respectively.
