Verdict
Period and TS Studios both sit at 4.9 stars, but that hides the real split: 100% of TS Studios's written reviews are positive against 54% of Period's. Period's advantage is ratings volume (2.4K vs 28) and update cadence (monthly vs every 4 months). On price, rating, ads and in-app purchases there is nothing between them.
