No. There are no profiles, no profile pics and no swiping. You trade letters with strangers who write like you, one letter at a time. Some become friends, some become your person, some stay lovely strangers — that part is up to the two of you. ### is it free? Yes. Fifteen strangers' letters on your desk a day, five new ones of your own to send, your courier and every correspondence — free, on iPhone and on the web. First Class is the paid fare: no cap on new letters, rooms that never close, voice letters (recorded in the iPhone app), the full wardrobe. ### is there an app? Yes — for iPhone, on the App Store. Sign in with Google or email and it's the same account on the web, so you can start on one and keep going on the other (Sign in with Apple is iPhone-only). On Android, your letters, kindreds and courier all work in your browser. ### is it anonymous? Completely. You are a number (like No. 4207) until you both decide otherwise. After five letters each way you can trade names — or not. ### how do you match people? By how you write, not what you look like. Sentence length, rhythm, whether you ask questions, how you end a thought — your letters go to the strangers whose writing runs closest to yours. ### what languages can I write in? Ten: English, 中文, Español, Português, Bahasa Indonesia, Français, Deutsch, Italiano, 日本語 and 한국어. A letter on your desk in a language you don't read comes with a translate key. The iPhone app itself runs in all of them but 中文 for now; you can still write in it there. ### how is it different from Slowly? Slowly matches you by interests and delays delivery by distance. Kindredly matches you by how you write, has no profiles at all, and your courier is yours — she hatches from your first words. ## something to read before you write - [The best anonymous journaling apps: where your private pages actually live](https://kindredly.io/guides/best-anonymous-journaling-apps) — A private journal only works if you trust where it goes.
