Hi Tyler, I am very sorry to hear that. It doesn’t sound right and we haven’t seen that in testing or had other similar feedback. There must be something unique going on. Could you please email us at help@pocketmariner.com so we can get you un-stuck as soon as possible. Best regards The PocketMariner crew

Response from developer

Hi, we are sorry to hear this. All SeaNav’s main navigation features and tools like routes, tracks compass and markers and the Apple Watch SeaNav app are free to use. Our charts are very competitively priced and are not free to us. We would love to hear more about how we could improve SeaNav’s ease of use for you. Could you please email us at help@pocketmariner.com with your suggestions. Best regards The PocketMariner crew
