# VIETSTEM vs VEXcode EXP

The clearest difference is in-app purchases: VEXcode EXP at none against VIETSTEM's 1. VEXcode EXP also leads on update cadence (every 6 weeks vs every 24 months). VIETSTEM's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 16.0). On price and ads there is nothing between them.

Both are free to download. VIETSTEM sells 1 one-off in-app purchase. VEXcode EXP asks for nothing beyond the download.

VIETSTEM ships an update every 24 months, VEXcode EXP every 6 weeks. The most recent releases landed on September 30, 2026 and September 29, 2026 respectively.
