From version 1.0.5 it sends nothing you type about yourself: a BooksOn sign-up request or a suggestion goes only as an email that you send from your own email app.

Every screen shows "Data updated as on" with the dataset version and the latest notification included. From app version 1.0.4, new notifications reach the app as signed data updates from this website, checked once a day (from version 1.0.5 on any network; a full new dataset downloads only on Wi-Fi) or when you tap "Check for updates now" in About, and with app updates from Google Play and Galaxy Store.

Choose monthly, quarterly (QRMP) or composition; the dates are worked out on your phone, and you can turn the alerts off in About. Check the GST portal for any extension before you file. The dates are listed on GST return due dates.

From app version 1.0.4, the app checks offline whether a GSTIN is correctly formed: its State code, the PAN inside it, the type of registration and the check character, which catches most typing mistakes. It cannot tell whether the GSTIN is registered or active; for the name, address, status and returns, the app opens the official Search Taxpayer page on the GST portal. You can also try the GSTIN check on this website.

Yes, from app version 1.0.4. Buttons and fields have spoken names, search results and calculator answers are read out, choices are marked with a tick and not only by colour, and the screens work with text up to 200%. The income tax PDF is not yet readable by screen readers, so use "Share as text" instead. Details and known limits: Accessibility.
