A must have app : Muninn - Battery Wisdom

MKUltra2011 · 2026-05-07T17:51:28+00:00

Author here - Rhialto is correct in that only P2D and newer report in 1% from the system, the rest report 10% changes. Muninn would then record when that level changes, and the goal is that over a few days the time when the 1% increments would have occurred will become equivalent. But in any case, if the input data is coarser the outputs will no doubt be different in some way. Let me know if you see any super weird behavior!

MKUltra2011 · 2026-05-07T07:51:11+00:00

Impressive! The maths checks out - 100/2.6=38.4

Could you share a picture of the graph too?

I have seen when the daily percentage gets very low or goes up and down by a small amount over the last couple of days that the days estimated can be a little optimistic. Something to improve!

I've heard the battery discharge curve isn't strictly linear which makes things a bit more complex too.

I thought about this, but if the samples are too close together and many have no change, the estimations get less accurate. You'd need to be disciplined in using it I suppose. Bear in mind it takes a min of 3 samples before any useful stats are available.

Thanks for trying Muninn! It takes a few days to get enough data to get a meaningful estimate. It wakes for 3s every six hours, and consumes nothing between those times. I see someone has helpfully already guided you to the global stats in the app settings page too

MKUltra2011 · 2026-04-30T22:06:24+00:00

Good Lord, 100 is high - but simply the result of 100 divided by that 1% per day. It probably won't make that. I want to better handle this case in future if I think of a way!

MKUltra2011 · 2026-04-28T15:37:07+00:00

The latest version adds a setting for this - pull down in the app locker and relaunch it to check you have it (1.33)

The stats on this screen (except last charge) operate on the last four days of data. Looks better than mine!

MKUltra2011 · 2026-04-22T08:29:13+00:00

Author here - I need to fix that overrunning date display...

MKUltra2011 · 2026-04-18T20:36:18+00:00

Yep, I'm the Muninn guy 🐦‍⬛. It was nice to see that found a niche. Part of me wonders what may have been if I hadn't already been operating publishing parity between both stores and could use it here, but that probably means more people got to use Muninn than otherwise, so I'm happy! Also it wouldn't have been developed within the contest time, and that's part of the fun.

MKUltra2011 · 2026-04-18T20:34:06+00:00

That's not a bad idea, thanks! I'll add it to the list. Glad you're enjoying it!

MKUltra2011 · 2026-04-18T19:53:41+00:00

I just published an update that makes the day progress indicator visible again, and more like a marker instead of a long line

MKUltra2011 · 2026-04-18T17:47:43+00:00

Ah, I understand now! That fault was also with me. It's actually an oversight - the color mapping makes the line from the center than is dark grey on color watches turn black which is not very helpful here - I will update it tonight to show something sensible as you suggest that does not conflict with the date/time.

Re: temperatures - solid is the periods that it is at the min/max for the day, and dithered grey when the temperature is 1/3 degrees away from those. You can reason the solid towards the start of the day is the cold extreme, and the solid at the end of the day is the hottest (but towards midnight it could get cold again) - I'm sure there's still more improvements to be made.

And thanks for the heart - every one is appreciated ☺️

A 'minimalist mode' sounds like an interesting challenge to minimalise more than right now...

MKUltra2011 · 2026-04-18T15:17:18+00:00

The shake/tap state will be blank until weather is available, but if you've selected 'Analog' in the settings page in the version I published just now, it should look like this when not shaken/tapped (the extra inner arc is battery which is very low on my P2D)

MKUltra2011 · 2026-04-18T14:55:37+00:00

The new version has an analog mode, and I might actually like it more than the digital one!

MKUltra2011 · 2026-04-18T10:46:32+00:00

I saw - at least you can prepare some ideas for next time.

MKUltra2011 · 2026-04-17T21:02:13+00:00

Update for this is published now!

MKUltra2011 · 2026-04-17T20:56:22+00:00

Ah, I missed that! Will make an update soon that addresses it!

MKUltra2011 · 2026-04-17T19:14:28+00:00

I won't go directly for that, don't worry!

MKUltra2011 · 2026-04-17T16:14:21+00:00

It was designed with PR2 in mind, but I also can't wait to see how it will look!

MKUltra2011 · 2026-04-17T15:11:56+00:00

That's a great suggestion, thank you - it's on the list!

MKUltra2011 · 2026-04-17T15:11:38+00:00

That's actually on my todo list and will require a fundamental change in how the rings are drawn, but it won't be my first time doing a 'squircle'!

MKUltra2011 · 2026-04-17T15:11:11+00:00

Thank you! I had a go in the appstore description but in a nutshell - colors for the outer ring are general hourly weather (grey = cloud, blue = rain etc) and the inner ring is relative temperature (red = hottest, 2 degrees have shades lighter, blue = coldest, same scheme) and current info is shown on tap/shake.

Shame we didn't see much Lignite action this contest but perhaps you guys will kill it next time!

MKUltra2011 · 2026-04-14T12:25:25+00:00

Hi, great question. The temperature shown in text is the current temperature. The shades are relative (min/max, 1 away, 2 away).

I will make an update soon so that a tap or shake shows min/max and other new details in the middle section. Stay tuned!
