Verdict

The call

The clearest difference is ads: Epoch at none against TimeLine's shown. Epoch also leads on review sentiment (82% vs 57%) and update cadence (every 5 weeks vs every 6 months). TimeLine's advantage is iOS requirement (12.0 vs 26.0). On price, in-app purchases, monetization model and device support there is nothing between them.
