I guess I can write two reviews?

Basically I’m trying to contact someone about making it so you don’t have to push reset and the date is automatically on todays date. Like I used the app yesterday and it’s still saying May 14 (today May 15) unless I reset that and I’m worried one day I’ll forget to reset and mess up the dates

Needs to be more accurate with weeks, months and years

Update
I love this app. The only gripe I have with this is that when you show more results, it only list whole numbers. For example, January 20, 2018 to May 21, 2021, it lists as
3 years, 4 months, 1 day
Months 40
Weeks 173
Days 1,217
Hours 29,207
Minutes 1,752,420
Seconds 105,145,200

I would prefer it to look like
3 years, 4 months, 1 day
Years 3.33
Months 40.01
Weeks 173.86
Days 1,217
Hours 29,207
Minutes 1,752,420
Seconds 105,145,200

Otherwise, this is a good app!

Response from developer

Thanks for reviewing my app. This is a very helpful opinion, but the calculation becomes quite complicated due to the difference in the number of days each month and the calculation of leap years. I will consider implementing it in a future version. However, the results in "Show more results" can be copied by long-pressing in version 2.4. Update: Finally, in version 2.5, you can specify how to calculate between dates. By changing the settings, you can now display in decimals. Thank you.
