PRIVATE BY DESIGN No ads, no analytics, no tracking. Your conversations belong to you, and you can delete your account โ and everything with it โ anytime, right from Settings.

Verdict
The clearest difference is in-app purchases: ZapYap at none against Fabius's 3. Fabius's advantage is update cadence (weekly vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
