Bait and Switch
Seaiq promoted its ability to handle the unencrypted s-57 vector charts like cm93. Many bought it for this purpose. Without notice or option to users the company discontinued this feature. All of a sudden for me hundreds of charts did not work including many I had created using this format. Whats worse is this happened in the middle of a sailing trip when I was so foolish as to update the app. I would stay away from a company willing to do this to its customers. When will they make the next decision making hundreds of dollars worth of charts useless. There are plenty of apps now with similar capabilities so the feature set is no longer as unique as it once was.
