Cambodia is ranked amongst the 4 most at-risk countries in Asia, according to the 2018 World Risk Report. The 2017 Climate Change Vulnerability Index ranks Cambodia between “High and Extreme Risk,” which implies a probability that climate change impacts will lead to a higher frequency of hydrological disasters both in terms of floods, drought and reduced water availability throughout Cambodia, ActionAid International Cambodian is designing a new project named Advancing Early Warning Systems in Cambodia under funding support from the GSMA -FCDO budget to promote an early warning system in Cambodia. The project aims to reduce the impact of disaster risk in target disaster-prone areas: 1) Ground Water Level Monitoring (GWLM) systems strengthened and expanded to additional disaster-prone areas to expand the coverage and impact of the mobile EWS 1294. 2) Communities have increased access to disaster early warning information through an effective and innovative mobile early warning system, EWS 1294. 3) Stakeholders’ coordination on disaster risk reduction and early warning systems is strengthened among relevant ministries and the national disaster management committee.

Verdict
The clearest difference is update cadence: EWS at every 6 weeks against Satark's every 3 months. Satark's advantage is iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
