Verdict
The clearest difference is review sentiment: Relief's Map at 51% against Zalo's 6%. Relief's Map also leads on rating (3.4 vs 2.1). Zalo's advantage is ratings volume (8.5K vs 14) and chart position (#129 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zalo sells 20 in-app purchases, starting at $0.99 per month and Relief's Map sells 2 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.
