# Estudy vs E

The clearest difference is in-app purchases: E at none against Estudy's 12. E also leads on ads (none vs shown). Estudy's advantage is update cadence (every 10 days vs every 2 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Estudy sells 12 in-app purchases, starting at $1.99 per month. E asks for nothing beyond the download.

Estudy ships an update every 10 days, E every 2 months. Both last shipped on October 28, 2026.
