If the changes to strings looks good I can go through and add translations based on existing strings/other library's translations

I thought it looked a little off, it was the commas!

Looking at the commit history, it looks like the original strings were added for this exact purpose (call duration) but never used.

I'm thinking it would be easier to just add the format specifier to the original strings using "Replace all" feature in your IDE.

As in, replace <string name="seconds_letter">s</string> with <string name="seconds_letter">%ds</string>?

[naveensingh]

Yes but not exactly as that would replace the localized versions with English.

[miapuffia]

Now what should be done with localizing day_letter?

[naveensingh]

We'll leave that to the (good) people translating via Weblate: https://hosted.weblate.org/projects/fossify/commons/

Not sure if there should be a space between number and text in some of those non-latin scripts but I guess we'll see.

Thank you!
