Verdict

The call

PepTracker and Pep AI both sit at 4.7 stars, but that hides the real split: 78% of PepTracker's written reviews are positive against 38% of Pep AI's. PepTracker also leads on ads (none vs shown). Pep AI's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (4K vs 468). On price, rating, in-app purchases and monetization model there is nothing between them.
