This app appears to predicts good fishing times based only on fixed factors like moon phase. Although it provides weather information, it does not take weather conditions (for instance temperature and barometric pressure) into account when predicting good fishing times. We used it for 10 days of fishing in lakes of upstate NY, and found there was no correlation between our success and the predicted "good" fishing times. We caught many fish during "bad" times and often got no bites during "good" times. I think the app would be much better if it took into account changes in barometric pressure when making predictions, since that is a known predictor of good fishing times. Dont waste your money on this app.
