Cota Rio tem o propósito de atender às necessidades da Defesa Civil, em parceria com aquaviários, visando o monitoramento contínuo dos níveis dos rios. Seu objetivo é possibilitar o registro de cotas, que são informações relacionadas aos níveis de água dos rios em diferentes pontos de medição. Essas informações são essenciais para a previsão de enchentes, tomada de decisões em situações de emergência e planejamento de ações preventivas. O sistema Cota Rio funciona por meio da colaboração de aquaviários e demais profissionais que atuam na navegação fluvial, permitindo a coleta e o envio de dados de forma contínua e descentralizada. Com isso, a Defesa Civil pode acompanhar as variações nos níveis dos rios em tempo real, garantindo uma resposta mais ágil e eficaz diante de eventos climáticos extremos.
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 6 screenshots above are COTA RIO's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: COTA RIO runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #1C3C8C) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #64842C, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
