Verdict

The call

The clearest difference is review sentiment: Period Log at 92% against BBTracker's 9%. Period Log also leads on rating (4.7 vs 1.0) and ratings volume (1.2K vs 3). BBTracker's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). On price and in-app purchases there is nothing between them.
