Verdict
The clearest difference is rating: Pi at 5.0 against Retrogram's 4.4. Pi also leads on in-app purchases (none vs 10) and review sentiment (100% vs 66%). Retrogram's advantage is update cadence (every 3 weeks vs every 57 months) and ratings volume (320 vs 1). On price, ads and device support there is nothing between them.
