Verdict
The clearest difference is review sentiment: RewardExpress at 100% against testraum's 0%. RewardExpress also leads on update cadence (monthly vs every 15 months). testraum's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.
