Since I fish everyday, I can really field test this app to the max! And its right on about the peak times! Not really sure about the Minor ones because sometimes theyll still be biting after the time period. Theres no secret to this. It just takes into account the phases of the moon and the weather to come up with a pretty accurate forecast! If this app says its a four bass day, youd better go out cause your gonna catch something! This app is more of a reassuring reminder of the peak times to be on the water. That said, I highly recommend this to every fisherman! It has the weather on it to, as well as a trophy room to keep your biguns in and share them via email or whatever kind of stuff you can post to all these social apps. Plus, you can get the lightning app, Spark, on this app for .99 cents. Highly recommend that too! Especially if your on the lake a lot. Get this app, youll like it.
