health tracking app - ideas for a log viewer

[enaon]

Hi, if I go to the health tracking app in the watch it self, I can see thet it has menus for battery and temperature, along movement, rate and steps. I do not see any ids for bat/temp on the object. Why are those menus on the watch?

require("health").readDay(new Date(), print)
{ "steps": 128, "bpm": 81, "bpmMin": 81, "bpmMax": 81,
"movement": 608, "hr": 0, "min": 0 }

I am trying to port my log viewer from the magic3 I use on the toilets, so that I can finally contribute back an app for the bangle. The logs format I use is very different, and I am struggling a bit to process all the data in a fast way, so that it feels like the viewer I have on the magic.

is there a way to have hours summary within the day, like days summary within the month, like this does?

// Read daily summaries from the given month
require("health").readDailySummaries(d, cb)

I cannot find an app that displays 10minutes info, But I would like to have that on the watch, may I suggest if possible for you to implement those options, so that processing the data would be easier? Or if you have any hits, It would be nice.

require("health").readDailySummaries(d, cb) // like you allready have

require("health").readHourlySummaries(d, cb) // so that I can get only the 24 hourly records or a given day

require("health").readSpecificHourRecords(d, cb) //so that I can get only the 6 10 minutes records for a given hour

this is my final version of the empty cycles log viewer on the magic3, it needs one more depth level to display inhour data for the 10 minutes entries for the health app, and the bangle.js 2 is bit faster, so I think it could work nice.

I think likely you could have only updated your health app this month? In which case the health log file is still in the old format which doesn't store that information? Next month it will update, or if you delete the file it'll create a new file in the new format which does contain all the data (but you lose the old data).

We have .readDay which gives you 10 minutes for the specific day? https://github.com/espruino/BangleApps/blob/master/apps/health/lib.js#L154

That's what we do for hourly graphs (which is effectively readHourlySummaries) : https://github.com/espruino/BangleApps/blob/master/apps/health/app.js#L104-L107

I'm hesitant to put into the main module as that gets pulled in and used a lot and more stuff could use more memory, but you could add a health_utils in https://github.com/espruino/BangleApps/tree/master/modules

yes this is the case. Just out of curiosity, how come battery and temperature are now in the health app, they do not seem very health related, why not in the recorder?

thank you, I will study it.

correct, but that is a huge amount of data. Say I want to graph the 10 minutes intervals for an hour, maybe between 5 and 6 in the afternoon.

Is there an app/web page that actually prints the 10minutes info, so that I can get some ideas as to how to handle the data.? Maybe I am missing something.

Because people asked for them. Battery itself is good as it can be used to track how quick battery drains - you could see that 'ahh yes, it started draining more 2 weeks ago'. Temperature as well could potentially be used for sleep logging or other things.

but that is a huge amount of data

Well, it's 6*24 - 144 records (so it's not that bad especially if you put it in a typed array). I guess we could give readDay an options object that lets you specify hours from/to quite easily?

I'm not sure. The health app used to, but there was a PR to change it a while ago to get rid of the extra data as someone thought it was distracting. I'm not really a fan of the change tbh. The health app basically does the work already (parsing all the data and then averaging it down) with https://github.com/espruino/BangleApps/blob/master/apps/health/app.js#L101-L107 - all you need to do is something like this to save all the data rather than averaging it:

    data = new Uint16Array(24*6);
    let n = 0;
    require("health").readDay(new Date(), h=>{
      data[(h.hr*6) + (h.min/10)] = h[options.field];
    });

thank you for all the links, I will study them, maybe I will learn something from your code :)

Well, it's 6*24 - 144 records (so it's not that bad especially if you put it in a typed array).

I am getting the feeling I am doing something wrong, it is 144 enties but if also has a lot of extra info, I did not manage to parse it fast enough, it felt slow on the viewer, but maybe my coding skills are that bad. I will try to understand you code a bit better.

if you ever get the time to add that option, I will use it, thank you.

Because people asked for them. Battery itself is good as it can be used to track how quick battery drains - you could see that 'ahh yes, it started draining more 2 weeks ago'.

as for this, I can see the point, ! do have a dedicated battery logger for the magic, a bit different as it has 4x21700 and lasts for months, it includes cleaning cycles usage and has a history of past sessions. Maybe in the future the bangle should have a battery app on its own, maybe using info from the E.getPowerUsage, maybe monitoring lcd led on time etc.

it would be nice if it recorded how much time the watch was unlocked or used. Then you could see how much battery went down while you used it. An addition to battery..

Thanks - yes, that could be neat. although I guess it's no use logging if the watch was in use every 10 minutes - we'd actually have to keep track of how long it was unlocked for and save that. It's something someone could easily do as an app though
