Verdict
The clearest difference is price: RetroKeeper at Free against Media Diary's $2.99. RetroKeeper also leads on update cadence (every 5 days vs monthly). Media Diary's advantage is in-app purchases (none vs 2) and iOS requirement (17.2 vs 26.2). On ads and device support there is nothing between them.
