Subathon Timer
Countdown that grows with every sub and cheer. Remembers time between restarts. ?hours=4&sub=300
A timer overlay for Twitch and OBS
Subathon Timer is a free subathon overlay for Twitch. Set a starting length, and every new sub, resub, gifted sub and cheer adds time to the clock automatically, with a floating “+5:00” and the supporter’s name each time. Tier 2 subs count double and tier 3 subs count five times.
The end time is saved in the OBS browser source, so the timer keeps running correctly through crashes, scene switches and PC restarts. Mods and the broadcaster can add or remove minutes and pause or resume the timer from chat, and an optional cap keeps a subathon from running forever.
- Subs, gifted subs and bits add time automatically
- Tier 2 and tier 3 subs add more time
- Mod chat commands: add, remove, pause, resume
- Survives OBS restarts and crashes
- Optional maximum length cap
- Floating “+time” with the supporter’s name
