Verdict
The clearest difference is review sentiment: Think3000 at 100% against Linuxer's 46%. Think3000 also leads on price (Free vs $6.99) and rating (5.0 vs 4.5). Linuxer's advantage is update cadence (fortnightly vs every 17 months) and ratings volume (22 vs 4). On ads, in-app purchases and device support there is nothing between them.
