Verdict
The clearest difference is price: Light OS at Free against Khmer Calendar's $2.99. Light OS also leads on update cadence (every 2 weeks vs every 3 months). Khmer Calendar's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 16). On ads and in-app purchases there is nothing between them.
