Good for stars etc.
This App is pretty good, but it could be a lot better. It doesn’t make use of the automatic stabilisation in the same way some other “long exposure” apps do, for example taking a handheld picture of a raging river with this App gives you nothing but a blur, whereas some other Apps will give you fabulous results in the same conditions. Bottom line, unless you bring your tripod with you, don’t bother with this app.
