Verdict
The clearest difference is price: Level.. at Free against Slope Level RX's $1.99. Level.. also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). Slope Level RX's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On in-app purchases there is nothing between them.
