From the New Concise Pali English Dictionary:
work, occupation; activity, performance.
act, deed, action or actions of moral import (producing for the agent an inevitable result or consequence in the same or another life; the action appears to exist in some sense until the effect is completed)
an official act of the saṅgha (i.e. an action or ceremony agreed on and ratified by a properly constituted group of bhikkhus).
masculine (& n.)
action; work, task, business, occupation (esp. farming, agriculture); place of work (esp. the fields).
Kammanta is the basic or 'stem' word for kammanta.
Note: In the sutta quote below, the word 'kammanta' has been translated as both 'work' & 'workplace'. In the sutta below:
'kammante' appears to be the accusative (object of a verb) case of 'kammanta' , i.e., "supervising (verb; anusaññāyamāno) the work (object; noun; kammante)"
'kammanto' is the nominative (subject) case of 'kammanta', i.e, "Moggallāna’s workplace or Moggallāna’s work".
For just then the brahmin Vassakāra, a chief minister of Magadha,
while supervising the work [plural] at Rājagaha, approached Ānanda at
Moggallāna’s workplace [singular] and exchanged greetings with him.
Atha kho vassakāro brāhmaṇo magadhamahāmatto rājagahe kammante
anusaññāyamāno yena gopakamoggallānassa brāhmaṇassa kammanto,
yenāyasmā ānando tenupasaṅkami; upasaṅkamitvā āyasmatā ānandena
In your situation, if you named your app 'The Work App' or 'Sunyata's Work App', the Pali would probably be (merely guessing) 'kammanta' because the word 'kammanta' would be an adjective and form the first part of a khammadharaya (merely guessing) word compound, as follows:
When nouns join together with two or more words they are called
nominal compounds or samāsa. The first member of a compound can be
another noun, an adjective, an adverb, a pronoun, a verbal form, or a
numeral. In general the last member of the compound gets inflected
according to its declension while the other members keep their stem

Therefore, your app might be called:
