# NVS Tsunami Evacuation vs PSE

The clearest difference is review sentiment: NVS Tsunami Evacuation at 44% against PSE's 14%. PSE's advantage is rating (3.9 vs 3.5). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PSE holds the better App Store score, 3.9 against 3.5. Both are backed by a comparable volume of ratings — 19 and 14 respectively. Written reviews complicate that: 44% of NVS Tsunami Evacuation's written reviews are positive against 14% of PSE's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on June 11, 2026 and September 18, 2026 respectively.
