Show HN: I built desktop app for keeping track of your PC gaming sessions

https://store.steampowered.com/app/3879010/Sentinel_Signal/

Hi everyone! I've been working hard to deliver my application to Steam and now it is released!

Its purpose is to help you better manage your gaming sessions. It can automatically detect when you run your games, track the gaming time, let you set weekly gaming goals, a gaming session limit and send you visual and audio notification when you are close to your gaming limit. You can also flexibly extend your gaming session up to a degree while you are in game to ensure that you can finish up your current session as you needed.

Currently it only works for Steam games. I would be happy to hear your questions, comments and feedback.

Being limited to a single platform, and then to a single store is a huge drawback. Some games, like Alan Wake 2, are Epic exclusives. Do you plan to address that?

Personally, I solved the issue by decoupling the whole idea and just manually tracking time. As a bonus, you could track other activities like work. Link in the profile.

sentinelsignal•3mo ago
That is a very good point. Thank you very much for your comment. Yes, I am aware of this drawback, I have plans to address this point at later stages but for the initial phase I wanted Sentinel Signal to be really focused on solving core problem very well for Steam gamers and work right out of the box with no need to do manual tracking.

At some point I will probably expand game detection to other platforms but I will ensure that it will have extremely high accuracy before doing so.

Devil’s advocate here. Huge drawback is a relative POV considering the vast majority of people who play computer games do so on Windows, using Steam. I feel it worth mentioning that the HN crowd may be biased in ways that your other users don’t care about. Joe Schmo on Windows using Steam doesn’t care if you expand out to Epic Games on FreeBSD or whatever instead of adding more featurez. Best of luck with your app, it looks cool :)

Thank you very much! My feeling is also similar to yours, that is why I initially purely focused on Steam platform though even for Steam platform our audience is kinda niche I feel like but let's see what the future will bring.
