Slowly (app)
Hong Kongese delayed messaging application
Slowly (stylized as SLOWLY) is a geosocial networking application that allows users to exchange delayed messages or "letters". The time taken by a message to be delivered depends on the distance between the sender and the recipient.
History
Slowly was released on iOS in 2017 and on Android a year later. It was featured as App Store's "App of the Day" in over 30 regions worldwide. It was also awarded 2019's "Best Breakthrough App" by Google Play. By January 2019, it had reached 1 million users.
The Slowly web application was launched in version 5.0, in mid-September 2019. In 2020, features such as Dark Mode, the ability to exchange audio notes and to pass a letter without it affecting the user's sent/received ratio were introduced in version 6.0 of the app. A paid membership feature called SLOWLY PLUS was also launched that allows members to double their quotas for the number of friends, excluded topics and regions, and photo sharing.
In September 2023, Slowly launched an Open Letters.

Why this record matters
“Slowly (app)” is worth following because a concise public description often conceals a longer documentary argument. Here, Slowly, Hong and Kongese provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 9, 2025. The linked authority identifier is Q98139720. The first chronological checks are 2017, 2019, 2020 and 2023.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
