I was really hesitant about paying 99c for this app, with no reviews, not sure if it would work or not, but I’ve been testing it out all morning, This app does exactly what it says on the video preview, I love it, I’ve tried every free app on the AppStore, which most didn’t work, or after you took your shot it wanted you to pay excessive monthly subscription price, and you couldn’t save it If you plan to use this, the main tip I would recommend, turn off your auto screen lock, screen doesn’t do it automatically, maybe developers could add this feature in next? Annoying to record to have screen shut off, Also use a tripod, you don’t want your phone to move,and best shots are early morning or dusk, too dark and image is dark, Last tip for developers, when searching for long exposure in the App Store, this app doesn’t show up near top, I found it by accident using google,
