# Even-Analogous Apps

Ideally we'd like full feature parity with the stock Even app (or at least,

close enough that not-using the stock app doesn't feel like a sacrifice).

A rough list of things the stock app has that we currently don't:

## Quicklist

Quicklist is Even's version of a todo app, in the form of a dashboard card

that you add to and remove from with assistant voice commands. It's pretty

simple to build once a general voice assistant is in place, but I don't

actually like their design: a todo list really wants to be synchronized

with something external like Roam or Notion, so I think it'd be better to

build one of those integrations instead.

## Stocks, News

Even has a dashboard card which is a stock ticker. I think this is probably

misguided; while there do exist people who would want and benefit from a stock

tracker on their glasses, I do'm not sure there exist people who would want and

benefit from a stock tracker that isn't a professional-tier tool connected

to carefully chosen low-latency data sources, and neither I (nor Even) can

build that tool.

The News dashboard card is more broadly useful, but has a similar issue: a

generic news ticker isn't really useful without a much higher degree of

customization. Probably the right thing to build instead is more like an RSS

reader.

## Ring Connection Management

The stock Even app is responsible for pairing the glasses with the ring (ie,

sending the glasses a configuration messages telling it to connect to the

ring's MAC address). If you pair them in the stock app and then switch to a

custom app, they remain paired indefinitely (this configuration is stored in

flash), and our custom app can make use of the fact that they're paired.

We don't yet have support for connecting or disconnecting the glasses and ring

to/from each other. For latency reasons, it would be nice if we could unpair

the glasses from the ring and connect the phone to it directly; we don't yet

support that either.

## Ring Health Metrics

The R1 ring contains an oximeter-style LED sensor and an accelerometer, which

can be used for a step count, heart rate measurement, etc. I'm not sure

whether the sensor interpretation is done within the firmware (in which case

it would make sense to display them in the UI) or in the Even phone app (in

which case we'd be reimplementing all the interpretation algorithms, which

isn't worth it.

## Navigate

Even has a Navigate app, which is basically Google Maps for the specific use

case of "name a destination, get turn by turn directions to there". I believe

this is using Mapbox, which takes care of most of the heavy lifting (if you

have an API key). I don't think Even's version is very good (they ran into

trouble with image-upload performance preventing a good map display size), so

it's likely not too hard to do better. One caveat is the location permission;

Android normally only wants to prompt for location permission "while using the

app", but Android's idea of in use (phone screen unlocked and window focused)

doesn't match our idea of in use (G2 glasses on, phone could be locked). This

app also gets a lot better if we figure out how to use the device's

magnetometer (if it indeed has a working magnetometer).

## Distance/Viewport Configuration

During glasses onboarding, the stock firmware has you select a vertical offset

for the screen image. This accounts for glasses resting at different positions

on your face (the optics don't let you see the whole screen area), but cuts

the usable screen height from 480px to 288px. There is also a "distance"

config option in the stock Android app, which adjusts the horizontal position

of the image on the two lenses separately to create the impression of the

image being closer or farther; this cuts the usable screen width from 640px to

576px. Unlike the vertical size reduction, this 64px reduction is not

optically necessary.
