SW array vs Signal Generator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SW array
This tool simplifies calculations for speaker arrangements, offering guidance for various configurations like Cardioide, End Fire, and Arc Delay. It processes data internally without exporting user information, ensuring privacy.
- Cardioide arrangement calculations
- End Fire array configurations
- Straigth array setups
- Arc Delay with coverage angles
- Internal data processing
- No user data export

O Subwofer Array (SW array) é uma ferramenta para facilitar os cálculos dos arranjos. Usa como referência caixas “omnidirecionais” e indica os dados para auxiliar montagens dos arranjos: -Cardioide (com caixas opostas e caixas em mesma direção) -End Fire (1/4 λ até 4 caixas) -Straigth (2/3 λ 4,6,8,12 caixas) -Arc Delay (Delay/Físico com cobertura aproximada: 15o, 30o, 45o, 60o, 90o, 120o Aviso “O SW array é uma ferramenta para facilitar os cálculos, portanto, não tem o objetivo de ensinar as técnicas e não se responsabiliza por danos aos equipamentos. ” Os dados inseridos no aplicativo são processados internamente. Não há qualquer exportação de informações do usuário ou mesmo dos dados inseridos. Não há acesso externo.

Verdict
The clearest difference is review sentiment: SW array at 100% against Signal Generator's 0%. SW array also leads on iOS requirement (15.1 vs 17.0). Signal Generator's advantage is price ($4.99 vs $8.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
