Verdict
The clearest difference is price: XSpecApp at Free against CrystalGen's $2.99. XSpecApp also leads on update cadence (every 2 days vs every 38 months) and iOS requirement (8.0 vs 17.2). CrystalGen's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
