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.

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.

​Great app, but needs proper Arabic text support! ​Unlike English, Arabic flows Right-to-Left (RTL) and must align to the right. Currently, Arabic paragraphs look misaligned and distorted in Flexcil. ​Please add: ​Alignment: Align Right, Center, and Full Justification. ​Checkboxes: Interactive task boxes. ​Lists & Bullets: Numbered lists, bullets, dashes (-), and checkmarks (✓). ​Proper RTL support and basic formatting will greatly improve the app for Arabic users!

Thank you for the detailed feedback. You're right that our RTL support needs work, and we've passed this along along with your formatting requests. If you could email [email protected] with more detail, it would help us a great deal. Thanks!
