Is it possible there is NO App for this one?

Hi there, i have spent several days trying with all sorts of search phrases to find an app that does what i need.

The problem seems to be that most apps in my direction are trackers that count movement, either on wearables or smartchies, and that's not what i am looking for.

I went through accounting apps and all sorts of others but so far nope, can't find it.

Here is the simple stuff i am looking for:
It has a calendar that always shows the current date on the side plus a simple entry box for meters (swum, run, bike'd, hike'd or whatever).
On a second page it should show the current months breakdown of all entries by date and distance plus the cumulative total for each month of the year as well as the same thing for years after years.
That's pretty much it.

It could have a multi user function, of course that would make it more interesting for community building, so a user login page plus maybe a page on which all users monthly and yearly distances are listed in top to bottom order. But again, this would just be an interesting extra.

In general what i want is to log my swimming distance MANUALLY and the app to do the math for me.

Any chance anyone in here knows of the existence of such an app, or if not what kind of free app builder program for amateurs like myself i could use to try and build this myself??

Hmm, beim Anmeldeprozess war ich mir aber ziemlich sicher dass das alles auf EN serviert wurde, ansonsten haette ich sicher gleich auf DE geschrieben. Kann es sein dass euer System mir ne EN version lieferte weil ich gerade in Rio bin??

Da fehlt dann aber das ganze mit den täglichen Distanzen die schön zusammen gezählt / addiert werden , jedenfalls stand davon nix in der Beschreibung der Textversion...
