While I like the app, the lack of auto backup is really inconvenient and potentially risky as you can lose everything. There is no means to share notes across devices which is a major downside. Also I find that notes with no cover option sometimes does not show correctly on the document view (bug). I will give another * if favorites don't show in random order on the document view but can be shown either sorted alphabetically or can be user arranged.

Sorry for your inconvenience. We fixed the issue and updated the app. Please update the app to the latest version. Once again, we apologize for any inconvenience this caused.

Please add the option to expand or stretch PDF margins! When annotating dense documents, we desperately need extra blank space on the left and right sides to write notes directly next to the text (similar to Notein's canvas expansion). Flexcil is amazing for stability, but this one feature would make it complete. Please consider adding it in a future update!

It's a good app, I can use it well on my tablet.. however, it doesn't sync across devices (windows, ios, mac, android). i disappointed with flexcil because of that. flexcil also doesn't have its windows app and their web viewer is sucks. i really hope that at least you build one for windows and make it easier to sync across devices.

Thank you for the feedback. Google Drive sync does work across iOS, macOS, and Android when Premium is active on each device. We don’t have a Windows app, and we’ve passed your request along to the team. Thanks for letting us know.
