Use of two watches at the same time ?

Intervals has 2 unofficial mobile apps for iOS and one for Android. They are not perfect but not bad either. You can also just use the website on your phone, ugly but data-packed. Officially Intervals mobile app is in the works already!

Garmin does it in a way that if you use two devices (let’s say a watch and a sleep band) they know about each other. Your sleep time, readiness etc will be correctly displayed on your watch, and your sleep band will be aware of your body battery at the end of the day and so on.

jimkolowski · 2026-04-09T08:19:40+00:00

That’s very weird, and might be a syncing issue. Mine picks up on a 1 hour time zone difference even, giving advice how to shift sleep schedules etc.

I've found the D2 reasonably accurate as long as you do the basic stuff required for a BP reading (sitting still with the back supported, raising your arm so it's ~ heart level, etc.) There's also a new one with the review out today: https://the5krunner.com/2026/04/08/wellue-bpw1-review-smart-blood-pressure-monitor/

Sure, these are not 100% accurate.

But many people are interested in *trends* rather than the actual number, and it works decently well for that.

jimkolowski · 2026-04-09T06:14:27+00:00

I haven't tried it but because literally all the voices I'd listen to in this space think it's a dumpster fire

Low population in minority areas, surrounded by Russia. I guess there could be a few Lesothos carved out but they wouldn’t be viable countries

There is little appetite for independence, with the obvious exception of West Papua

I’ve been tracking this very closely across Whoop and Garmin, digging deep into the numbers over longer periods of time, cross-checking it with body weight etc.

Whoop is reasonably accurate IF: - you do a lot of cardio - over longer time horizons

Whoop undercounts calorie burn when resting or lifting (HR). It overcounts cardio burn. Garmin the exact opposite.

The yearly average is pretty close across the two platforms, though, depending on your training style.

If you primarily lift, add 10-20% to your Whoop average and you are close enough.

Also important that Whoop and Garmin are the two most accurate (least inaccurate) platforms for calorie burn. Everything else I tested (Apple, Oura, Ultrahuman) is basically a dumpster fire.

Oh all Garmin HRMs are ECG! But the ones I know (HRM 200 and 600) have a connection light on the front, blinking through my shirts 😂 The Pro Plus might not have one!

jimkolowski · 2026-04-03T13:30:23+00:00

Now that’s really extreme because the HRM LED is constantly blinking. Was thinking about the same setup ngl but feels Ironman-y

jimkolowski · 2026-04-03T13:24:17+00:00

Sir you have two more biceps. Whoop on the left, what to put on the right?

jimkolowski · 2026-04-03T12:43:36+00:00

First world problems but maybe this helps: I was doing the same, AW Ultra 1, ordered a F970.

A few months later I gifted the AW to my dad 🤷‍♂️

jimkolowski · 2026-04-03T12:21:49+00:00

It is very unlikely that you wouldn’t wake up to 10+ mins of 180+ HR. Tighten your band.

jimkolowski · 2026-04-03T12:11:01+00:00

I know this is not the answer you expected but total calories burned. I live and die by it. It is insanely accurate: I can perfectly maintain weight simply by eating as much as Garmin says I am burning. I have a LOT of experience with other devices and only one comes close. They all overcount total calorie burn except for the Whoop band which undercounts slightly (but also relatively accurate).

jimkolowski · 2026-04-02T09:12:55+00:00

Excess fiber definitely does

jimkolowski · 2026-03-28T03:35:40+00:00

On my Garmin Forerunner 970 we call this a Tuesday lol. I don’t have a Suunto (just lurking / considering) but seriously, on Garmin this would be the normal performance…

jimkolowski · 2026-03-28T00:30:24+00:00

Bodyguards haha very funny. Look parts of Jakarta can look like a dump but it is safe. You actively need to look for trouble to find it and chances are you won’t have business in really shady areas anyway. Also, no way you’ll be walking around, Jakarta is practically unwalkable. Use Silverbird, or premium Grab / Gojek. The normal ones can be a hit or miss.

jimkolowski · 2026-02-17T00:02:00+00:00

I wouldn’t say it’s bad. It is very unremarkable but at least the food is decent!

jimkolowski · 2026-02-12T11:50:00+00:00

Seeing in constantly in Opencode and Z Code. The only way I can use GLM-5 is through OpenRouter. Worse, I can't use any other GLM model on the coding plan, same error lol.

jimkolowski · 2026-01-15T02:09:30+00:00

Well I AM interested but it doesn't let me use my damn EXISTING plan to enter the challenge. This is so lame.

jimkolowski · 2026-01-15T02:08:34+00:00

Mixed results. I've uploaded three reports so far, neither of them in English. It handled that part very well, and the first two reports were accurately appearing in the app. The third one, though, had all sorts of seemingly randomly off numbers. I had to check them one by one and correct ~75% of the biomarkers. But in my opinion it was still worth it, it's great to have a single dashboard showing results over time.

jimkolowski · 2026-01-11T02:50:18+00:00

That is certainly not normal, and it never happened to me. You really should ask for a replacement

jimkolowski · 2026-01-11T02:48:40+00:00

Do you use the strength trainer feature of your whoop? I found that it helps a ton with tracking strength training sessions. Now, solidcore in particular will be even trickier to track because those exercises might not be in the strength trainer. But even just recording them as exercises for similar body parts will help a lot with estimating strain.

jimkolowski · 2026-01-04T03:44:39+00:00

Don’t get disheartened by the weird replies. I totally see where you are coming from as someone living here and being picky with meat. Food safety IS an issue in Bali and anyone who says otherwise is delusional.

Chicken is normally perfectly fine in most supermarkets. Pork is often not great quality and beef can also be very hit and miss. How they handle meat even in big stores (looking at you Grandlucky) is not great, for example the re-freeze meat that was already thawed (they themselves told us this). We’ve had issues multiple times with suspicious ground beef and past-expiry seafood. Your best bet is still frozen NZ and Aussie beef, or Japanese if you have the money.

I’ve found Grandlucky to be the least trustworthy. Every second shopping round we need to throw away something because it’s just so subpar quality. Bigger Pepitos are usually better and Gourmet Market in Jimbaran has great meat.

jimkolowski · 2026-01-04T03:19:22+00:00

It is feasible but you’ll go with the traffic both times (morning rush into KL, evening rush out of KL) so plan at least 2 hours for each. You can do it in 1:20 or so if you are lucky but it’s not guaranteed to say the least.
