Comparison
Crab Fit alternative: how whenfor.us compares
Crab Fit is a lovely project: free, open source, ad-free, and built by one developer with donations. If it works for you, that's great. If you're looking around, here's how whenfor.us differs.
What Crab Fit does well
- Free and open source, funded by donations.
- A live heatmap of everyone's availability.
- Available in many languages, with an Android app.
- Events are deleted after three months of inactivity.
Where whenfor.us goes further
| whenfor.us | Crab Fit | |
|---|---|---|
| Answering | Drag over free times | Drag over free times |
| Accounts and ads | None | None |
| The answer | Heatmap plus a sentence naming the best time and who it works for | Heatmap |
| Time zones | Automatic: each person sees their own local times | Time zone chosen when the event is made |
| Languages and apps | English, in the browser | Many languages, Android app |
| Open source | No | Yes |
On top of that, the organizer picks the final time on whenfor.us. Everyone sees "It's on!", can add it to their calendar in one tap, and the organizer gets a picture and a ready message to post in the group chat. You can also give each event one of four looks.
Which one to pick
If you need another language than English, an Android app, or you care about open source, Crab Fit is a great choice. If your group mostly answers from a chat on their phones, spans time zones, or you want a clear moment where the time is picked and shared, whenfor.us is built for exactly that.
