Verdict

The call

The clearest difference is review sentiment: Instock at 75% against Tradeblock's 35%. Instock also leads on rating (4.7 vs 4.4) and iOS requirement (13.0 vs 15.1). Tradeblock's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence, monetization model and device support there is nothing between them.
