Verdict
The clearest difference is in-app purchases: 1Rebel UAE at none against Zen Lean's 2. 1Rebel UAE also leads on iOS requirement (13.0 vs 17.0). Zen Lean's advantage is ads (none vs shown) and update cadence (weekly vs every 11 months). On price and device support there is nothing between them.
