App shows how much money you can spend daily to save the required amount of money until your next payday.
Additionally, you can compare prices of two articles of different weight/quantity/etc. or to find math relation between any values.
=========================
All data that you enter are stored locally on your phone.
No internet needed. No special privileges needed.
=========================
How it works:
1. Enter how much money you have just received
(you can do it anytime, the amount will be added)

2. Enter the date of your payday.

3. Enter how much you would like to save.
(the slider is only for the initially estimate of the amount. Its position will be not saved)

4. Enter how much money you have just spent.
(tap on the button "I've recently spent" to add every single next purchase you made that day)

5. Look at "daily I can't spend more than".

What means "daily I can't spend more than" (for instance $10).
Example:
If you spend today exactly this amount of money ($10), you will see the lower amount of money you can spend daily, but the next day you will see the same amount of money ($10).
(this is because the next day you will have one day less until your payday)
=========================
- app allows adjusting the font size on the main screen (tap on the left or on the right arrow).
- colors can be changed randomly on the main screen within certain limits of course (tap on colored wheels).
- English or Polish language (tap on the flag).
- Preview your last "I've recently spent" or "I've recently received" money (tap on the bag with money).
- "Undo last entry" works only within daily session.
- "Reset amounts" resets all amounts except the payout date.
=========================
App uses simple equation:
daily_I_can't_spend_more_than EQUALS (money_that_you_have MINUS you_would_like_to_save) DIVIDED BY (number_of_days+1)
=========================
How to compare prices.
Example:
Article #1: orange juice - price $5, quantity 0,75 l
Article #2: grapefruit juice - price $6, quantity 1 l
Just Enter "price/value #1" as 5 Enter "price/value #2" as 6
Enter "quantity/value #1" as 0,75 Enter "quantity/value #2" as 1
You will see that the article #2 is cheaper than the article #1 about 10%.
=========================
How to find relation.
Example:
A car consumes 6.5 litres of fuel per 100 km.
How many litres of fuel will it consume per 250 km?
Just Enter "price/value #1" as 6,5
Enter "quantity/value #1" as 100 Enter "quantity/value #2" as 250
You will see that it consumes 16,25 litres per 250 km.
=========================
In general app is rather dedicated for those with less than more money because if you are a millionaire and for example you have just got $999999999999,99 and entered this amount by clicking "I've recently received"
you will probably see a mess on the screen. In this case just scroll the screen up and click the left arrow a few times to decrease the font size. ;)
