Other
What's the origin of the name Chronosky?
Initially, it was developed under the name "Chronopost," combining "Chrono" (meaning time) and "Post" for posting. I was considering using the same name for the service. However, I discovered it was the same name as a major French logistics service, so I changed it to "Chronosky."
The current name combines "Chrono" (time) and "sky" for Bluesky, representing a Bluesky tool for managing time.
I am also a fan of the video game "Chrono Trigger," which influenced the name.
Can I manage multiple Bluesky accounts?
Currently, Chronosky supports only one Bluesky account per Chronosky account. To manage multiple accounts, create separate Chronosky accounts.
Does it support Mastodon or Twitter (X)?
No, Chronosky is a Bluesky-only service. It does not support other social media platforms.
Are there plans for a mobile app?
Currently, mobile app development is not planned. However, the website is accessible via mobile browsers.
Is there a feature to post template text at regular intervals?
No, we do not implement a feature for repeatedly posting template text. Repeated posting of template text becomes noise for the entire post stream when left unattended, so we will not provide this feature.
How do I contact support?
Support email address is in preparation. Please wait.
