Verdict

The call

[solidcore] and daily.spark both sit at 4.9 stars, but that hides the real split: 100% of daily.spark's written reviews are positive against 21% of [solidcore]'s. daily.spark also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 6 weeks). [solidcore]'s advantage is price (Free vs $8.99) and ratings volume (29K vs 9). On rating, in-app purchases, device support and iOS requirement there is nothing between them.
