Verdict
The clearest difference is review sentiment: Oculock at 100% against SL Calendar's 33%. Oculock also leads on rating (5.0 vs 4.5) and update cadence (every 2 weeks vs every 9 months). SL Calendar's advantage is in-app purchases (none vs 2) and ratings volume (52 vs 3). On price, ads, device support and iOS requirement there is nothing between them.
