Upgrades

(Note: If you already bought in-app upgrade but it’s not recognized by our apps please see this FAQ article: In-app upgrade troubleshooting)

Our apps use the freemium model, similar to many mobile apps these days. The basic version is free and displays ads. The free version has enough functionality to serve the most common user needs. Users can check if the app works for them without paying anything.

What we hope for is a significant number of users will like our apps but found the feature set in the free versions limited in some way and choose to upgrade to access premium features. These are serious users who want to keep the app installed and use it everyday. Maintenance and further development of our apps are funded by paid upgrades.

Remove Ads

We know ads are annoying. We personally don’t like ads either. But it is what it is. Most free apps these days try to earn money via ads. In our case the ad revenue is pretty small but at least something. If you don’t want to see ads in our apps, please pay a small amount for this upgrade.

Pro Upgrade

This upgrade unlocks the following premium features

  • You can sync multiple pairs of folders
  • Upload large files. The free version can upload files up to 10 MB. That should be enough for documents, photos and MP3. But if you want to upload large video or backup files, you need this feature. Please note that there is no limit to download file size even in free version.
  • Resumable upload / download. If sync was interrupted, at next try app will continue to transfer from the position where the previous sync failed. Otherwise it would need to restart from the first byte and may fail again, and may need to restart again from the first byte,… This is not a problem for small files but is a big thing for large files, especially over flaky mobile network. It works for both downloads and uploads.
  • PIN / passcode protection. Users need to enter a secret passcode to use the app. Important for devices used by multiple users (say tablet used by your kids to play games), or if you worry your device may be stolen. Data sync is powerful but if the app is misconfigured it may create a mess in your cloud account or in your device storage (unwanted file deletions, unwanted file uploads, downloads,…).
  • Intelligent change detection. Some cloud storage services are able to tell the app if any changes were made on their side and if so they can report the changes incrementally, since the last sync. Apps can make use of this feature to drastically cut down sync time, save data bandwidth and minimize battery consumption.
  • Sync the whole cloud account with a folder in your device. Most people don’t want nor need it but if you really want to you can.

Ultimate Upgrade

This upgrade unlocks all premium features, same as Pro upgrade level but with two important difference:

  • Pro and free versions can only sync with one cloud account. With Ultimate version you can sync folders in your device with folders from multiple cloud storage accounts. Dropsync Ultimate can sync with multiple Dropbox accounts, DriveSync Ultimate can sync with multiple Google Drive accounts,.. This is useful if you have one personal account and one or several accounts for work or school.
  • Ultimate upgrade will also unlock all premium features we’ll add in the future. Buying Ultimate Upgrade essentially means pre-paying for all future enhancements, lifetime, all-you-can-eat kind of thing.
How many devices can I use my upgrade license on?

You pay for the upgrade once and can use it on multiple devices. Devices under one license must belong to and are used mostly by one user. Having 5 devices (phones + tablets + Chromebook) with the same license is totally fine. Using the one purchased license on 20 devices is definitely not fine. Email us if you want to buy upgrade licenses for many users at once.
