The call

The clearest difference is rating: TTLock at 2.9 against PETJC's 2.0. TTLock also leads on review sentiment (25% vs 0%) and ratings volume (547 vs 4). PETJC's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence and in-app purchases there is nothing between them.
