When can I use Lertha?
Lertha is pre-launch and in private testing. The waitlist is open, and it is the only way in for now.
Lertha is pre-launch. The app is in private testing and the waitlist is open: joining it puts you in line for early access, and we email the address you gave us when there is a place for you.
We are deliberately not publishing a launch date. When we have one we can keep, you will get it by email rather than reading it on a marketing page.
At launch Lertha will be available on iPhone, on Android and on the web, with the same account behind all three.
Still stuck?
Ask Lertha reads these pages and cites them. If it cannot help, it passes your question to the team and a person replies by email.
