This started out a a successor to Note to Self (which doesn't seem to work anymore) and evolved into a suite of simple tools, all accessed from a voice prompt.
There's no AI, subscriptions, API keys, or cloud dependence (except for weather forecast). Everything is done through deterministic text parsing. It's designed to function with as few button presses as possible. The default settings will immediately start dictation when the app is opened. As soon as the dictated input is confirmed by the user it routes to the appropriate function, then the app closes it's self when it makes sense (currently pin-drop and timer). I'm still working on the UI portion for most of the tools, and would really like some ideas for some other useful quick-tools that can be accessed from a voice prompt.
Current tools:
Pin/Note
Drop a pin on the timeline as either a reminder or a note for posterity.
Example prompt: "remind me to pick up lunch at noon"
Timer
There are many timer apps, but this one is mine.
Example prompt: "set a timer for five minutes"
Tip Calc
Supports calculating tip percentage and bill split.
Example prompt: "twenty percent tip on fifty seven dollars, split three ways"
Calculator
Just a simple calculator.
Example prompt: "what is twelve times thirty six"
Unit Converter
Convert common units for mass, distance, speed, volume, etc.
Example prompt: "how many tablespoons in one and a half cups"
Weather Forecast
Queries Open-Meteo for weather.
Example prompt: "what is the weather tomorrow"
Timezone Query
Fetches the current time for another geographical location.
Example prompt: "what time is it in Hawaii"
