As simple as it's stated in title.

• setup in a form of <date> !budget [weakly|monthly|...]
• notifications on main page if it's exceeded or almost exceeded
• money left and days left for every budget
• "red line" on plots, related to this period, if it makes sense
• some random funny idioms or citations about saving money? :)

Something like this

2015.10.02 food, sweets 123 delicious cakes @not-at-home
2015.10.02 clothes 1234 @she
2015.10.02 clothes 1234 @he
2015.10.02 food, sweets 123 @not-at-home delicious cakes @some-tag
2015.10.02 food, sweets 123 delicious cakes #not-at-home
2015.10.02 food, sweets 123 #not-at-home #some-tag delicious cakes 

I'm pretty sure there should be no white spaces in tags.

Weekly expenses by categories like monthly expenses with table view.
Ability to setup first week day and to setup non-week periods.

Something like this:
2017.08.02 !periodic 200 mobile connection
which during calculations adds corresponding "imaginary lines" after this entry.

Some very simple representation would go for the first time.
It's discussable what way to choose.

1. Show the tail of money.txt, because there is no way (by design) to determine actually the most recently added entries.
2. Show recent expenses and incomes sorted by date.
   NB: try to make the view compact.

Something elementary would go for the first time.
Capabilities to:

• enter entries as text lines (one text field)
• validate the input
• if succeed, append to money.txt (at appropriate position?)

Problem

Current format is fairly limited, and not always obvious.

• date have to be the first in the line, and have to have yyyy.mm.dd format. You can not write date at the end of the line, in brackets, or in yyyy/mm/dd format,
• it is not possible to distinguish income and expense in one line. For example, when you withdraw money from card,
• it have no support for multiple currencies and/or sources for conversion -270sber + 10$,
• you cannot write money.txt as a human.

Proposed solution

Make format more flexible and text-like. Successfully parse any line into something. Use optimistic parsing, defaults, free format.

• scan a line to find a date like 2016-12-06 in some standard format,
• --//-- all parts of money numbers -1 or 7,
• --//-- #hashtags and @mentions,
• use whole line as a note,
• add optional suffixes for money numbers, like 3$ or 5700vtb to mark different sources and currencies
• use not positional, but text syntax for marking categories. I suggest prefix bang !food,
• allow multiple categories instead of tree-like category structure,
• add defaults for all fields,
• get rid of complex math in expressions.

Additional proposion

Companion application should only help analyze money.txt. Everyone can write and save text file on any device already.

Examples

All examples have note equal to whole line,

Any line with date 2016.12.06 and no numbers
-15
Bought a #flower -2$ 28.01.2017.
!salary at #DeathStar 123imperial_credit #stormtrooper
!Lost a -100€ bill today. I have no idea where did this happened! So embarrassing (Later that day) Yay! I !found that 100€ bill in a pocket. So happy)
Пришлось потратить -19р на трамвай маршрута №432 на Зелёной улице. @Джуффин об этом не предупреждал

• Any line with date 2016.12.06 parse to
  • date=2016.12.06
  • default currency numeric expression=0 (default)
• -15 parse to
  • date=2016.12.06 (default: same as last one before)
  • default currency numeric parts [15]
• Bought a #flower -2$ 28.01.2017. parse to
  • date=2017.01.28
  • numeric parts in $ [-2]
  • hashtags: [flower]
• !salary at #DeathStar 123imperial_credit #stormtrooper parse to
  • date=2017.01.28 (even if it makes no sense)
  • category [salary]
  • hashtags [DeathStar, stormtrooper]
  • numeric parts in imperial_credit [123]
• !Lost a -100€ bill today. I have no idea where did this happened! So embarrassing (Later that day) Yay! I !found that 100€ bill in a pocket. So happy) parse to
  • date=2017.01.28
  • numeric parts in € [-100, +100] (one can evaluate it to zero, but it's not the same)
  • categories [lost, found]
• Пришлось потратить -19р на трамвай маршрута №432 на Зелёной улице. @Джуффин об этом не предупреждал
  • date=2017.01.28
  • numeric parts in р [-19] (note, №432 starts not with a number)
  • mentions: @Джуффин

Move the development to master branch and make some README file for a fortuitous stranger.

The problem occurs (at least) at startup when network connection is not initialized yet.
