Verdict
The clearest difference is monetization model: ChartDay at freemium against aTimeLogger's subscription. ChartDay also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 86%). aTimeLogger's advantage is ratings volume (303 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.
