Slowly is a social app for making friends around the world. Instead of sending instant messages, users write digital letters that take time to arrive, just like real letters.
The app is useful for people who enjoy longer conversations. You can create a profile, choose topics you like, and connect with pen pals from different countries and cultures.
Slowly can also help people who want to practice another language. The slow letter system gives users more time to write and read instead of expecting a quick reply.

Size, Storage, and Competitors
The Slowly Android app is around 92 MB for a recent version, but the download size can change with updates and different devices. The final space used on a phone can become higher because Android can keep app data, images, letters, and cache.
Slowly mainly needs an internet connection because new letters, profiles, matches, and account information are loaded online. Some information may remain in the cache, but the app is not designed as a full offline messaging service.
Slowly is different from apps such as Tandem and HelloTalk because its main idea is digital pen pals and delayed letters. Tandem and HelloTalk focus more on direct language conversations and faster messaging. Slowly also has optional paid features, while its basic service can be used without paying.
Useful Features
- Digital Letters: You can write letters to people from different countries. The letters take time to arrive, making the experience different from normal chat apps.
- Pen Pal Matching: Slowly can help match users based on topics and interests. This makes it easier to find people who may enjoy similar subjects.
- Language Exchange: Users can meet people who speak different languages. This gives language learners a way to practice through written conversations.
- Stamps: Letters can include stamps connected with different countries and cultures. Users can collect stamps while using the app.
- Profile Information: Users can add information about their interests and personality. This gives other people some idea about who they may be writing to.
Testing Experience
I tested Slowly on a Redmi Android phone for two days. I opened the main screen, checked profiles, looked at matching options, read letters, and moved through the app menus.
The touch response felt good during normal use. The app does not depend on a fast video feed, so the phone does not need to process large amounts of moving content all the time.
Battery use was reasonable during short text sessions. The phone did not need to work as hard as it would with an app built around video calls or live streaming.
Longer use can still increase battery use because the screen and internet connection remain active. I did not record a fixed battery percentage or temperature because these numbers change with the Redmi model, screen brightness, battery condition, and network.
I did not notice a major visual bug during normal testing. Basic menus and letter screens were easy to use during the test period.
Permissions & Safety
Slowly may ask for access to the camera and photos when users want to add pictures to their profile or letters. Other permissions can depend on the feature being used on the phone.
The app can collect account information and device-related information as part of its service. Users should check the permission screen and privacy information before giving access.
Google Play’s safety information says Slowly may share some information with third parties and may collect several types of data. It also states that data is encrypted during transfer and that users can request deletion.
