Hi,
@Mel dCP , I only used librelink for a couple of weeks, got xdrip running on my androidwear smartwatch by fluke/random button pressing without knowing much about what I was doing as it was my first evaah smartwatch, and I know nada about iphones as I always found Steve Jobs' penchant for polo necks kinda creepy, so I can't suggest much here!
You're basically just looking for a sort of post-it note reminder on your watch of what your last physically scanned reading was, whenever it was, without having an up to date cgm style reading?
Can't you just stick a post-it note on the watch? Nah, just kidding....
Can't think of a way of doing it automatically but maybe there's a Heath Robinson workaround with a few button presses.
I don't know what iphones and Apple watches are like, but on the android phone and watch I've got, if I was to scan libre, then put something in the phone calendar as an appointment for today and title it as, say, 5.6, or whatever my last scan or bg was, I can set one of the sub-dials or mini-dials or whatever they are called on the watch face to show calendar items. It doesn't show with a glance, I'd need to tap the sub-dial to bring up the entry, and then I'd see the 5.6, but there's maybe other watchfaces available which show the whole entry at a glance - or build your own - like I say, I know nothing about smartwatches. Scan, open calendar, type reading, save, sent to watch.
Maybe there's a way to text yourself the reading and have it show up as a notification on the watch?
Or, leave the phone aside altogether, open the timer app on the watch, set it to time down from 05:07, stop when it times down to sub 7 mins at 05:06: 55, there's you're 5.6. Scroll between the timer and the watch face as accords.
Automatic ways, hmm?
In xdrip+, even if you've not got a transmitter, there's an option for using it to physically scan as you would do with librelink, and as it's also got a function to send data to an androidwear watch or pebble, there's a veeery slim chance that might do it, but (a) xdrip is an android gig, so not much use for you Steve Jobs fans, and (b) the nfc scan function in xdrip is littered with warnings about it being very experimental and might kill the sensor, so I've never tried it and have no idea whether any scanned data would be sent to a watch.
I don't know whether Spike has a similar scan feature, absent transmitter. It's the new kid on the block for ios, based, as far as I can gather, largely on xdrip+ and seems to work with blucon and miaomiao so maybe worth a look for ios fans.

Miaomiao say it works with Spike and Spike works with ios so maybe worth looking at.

If you're swithering about getting a transmitter to send to a watch via a phone, I'd say go for it. I was in two minds about whether I needed bg on my watch, but it's been surprisingly useful for the sort of situations you mentioned earlier.
Don't know what the watchfaces look like in the ios/spike/miaomiao world, but in androidland, I've got this pic on my watch below telling me number, direction arrow, delta (change between last two 5 min readings), time since last 5 min read so I know when the next one is due, graph which can be tapped to rescale hours shown, and on the white line long press to show a card with general statistics such as day average, time in/high/low, and SD.
(Note to self: take another photo which doesn't show an underbolused Sunday curry and lager bounce to 7.7...)
