It is no longer possible to login or register with your Twitter account.
Twitter revoked access to its free API in April 2023 in favour of new paid plans, which are more restrictive. As Simply Remind Me is a free app, it is not feasible to pay Twitter for access to its API.
It is therefore no longer possibly to login or register to Simply Remind Me with a Twitter account.
Does your account have a password?
If your Simply Remind Me account has a password, you can login with your email address and password as normal.
If your account does not have a password
You can set a new one using the Forgot Your Password link on the login screen or the button below. Alternatively you can use a different social media account if it is linked to the same email address as your Twitter account.
