Verdict
The clearest difference is price: Wrumer at Free against XLR8's $4.99. Wrumer also leads on in-app purchases (none vs 5) and update cadence (monthly vs every 7 months). XLR8's advantage is rating (2.0 vs 1.6) and ratings volume (168 vs 5). On review sentiment, ads, device support and iOS requirement there is nothing between them.

XLR8 holds the better App Store score, 2.0 against 1.6.
