Verdict
The clearest difference is rating: Acidity at 4.2 against Snap Timeline's 3.0. Acidity also leads on ads (none vs shown) and monetization model (free vs ad-supported). Snap Timeline's advantage is update cadence (weekly vs every 4 months). On price, review sentiment, in-app purchases and iOS requirement there is nothing between them.
