Korice svih izdanja: dodirnite koricu da je vidite preko celog ekrana a onda je možete i razvući da vidite najsitnije detalje. • PRETRAGA KOJA NALAZI SVE • Jedno polje pretražuje sve: naslove i autore na oba jezika, biblioteku, izdavača, prevodioca i godinu.

Verdict

The call

The clearest difference is in-app purchases: YU SciFi at none against Thoughts's 3. YU SciFi also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 86%). Thoughts's advantage is update cadence (every 5 weeks vs every 76 months) and ratings volume (281 vs 5). On price and ads there is nothing between them.
