I have been using a notes app, Notesly+, since 2011. It offered a clean interface and most importantly for any data intense app, sync/backup to Dropbox. In early May I discovered that sync via Dropbox was broken. I tried deleting/recreating the account and got the same error. After running into the same problem yesterday I contacted the developer and was sadly informed that he has chosen to discontinue the product, even though the app is still available in the Windows Store. He went on to explain that he hasn’t had a sale ($0.99) in over a year.
It’s not surprising that apps will come and go as time moves on, but for apps that collect and store data on your phone, the pain is always a little greater. I can still copy info from the app and paste into another (or pull the raw data from the DB backup), so all is not lost. But’s it’s still a PITA. WARNING: If you are planning to upgrade to a new Windows Phone, check that you data capture apps are still active. If not, you make want to seek out alternatives now, before transitioning to a new device.
