Verdict
The clearest difference is in-app purchases: Tentacle Timebar at none against Previs Shot's 3. Tentacle Timebar also leads on rating (4.3 vs 4.0). Previs Shot's advantage is update cadence (every 2 weeks vs every 6 months) and review sentiment (80% vs 67%). On price, ratings volume, ads and device support there is nothing between them.
