O aplicativo é ótimo, mas tem muitos erros ao criar um plano de estudos DET. Até erros de SQL aparecem na tela

### 3/5 — This is fake app

*2025-09-29*

this is a fake app. No one should install this app because they they said me that we give you 10 credits. If you have paid three ₹349 when I paid this amount, they haven't given me any credits what they show on their profile. So never trust this app.total scam.
