The device supports Bluetooth LE, and offers HR and Sp02 readings.

Any chance of an Apple Watch companion app - would be helpful to have the heart rate tracking, vibration alerts and convulsion tap on a watch rather than on the phone screen.

Sometimes I have strong vasoconstriction and my hands get really cold and bloodless. There is need to able to use 2 devices simultaneously. For example I have Garmin chest strap for heart rate and Medisana pm 100 connect for oximeter. Since I only can currently use one device my finger oximeter is overwriting chest strap. Thank you for consideration

When doing my pranayama exercises, it would be nice to have the option to have a little countdown when starting so I have some time to set my phone down and adjust myself, rather than immediately beginning when I hit start

Under Tables/Create/Custom and below name of table there is an edit buttons. It would be great to be able each edit hold name. Instructors and apneaists would be able to use this for many exercises and for teaching. Personally, I use Stamina for dry dynamic exercises as well, and it would be great to input the name of each exercise to each hold and for it to say the name. Right now I use a piece of paper on the side, but the exercises are mostly always the same. For example; L twist, R Twist, squats, pack, exhale, inhale, RV, RV w/ reverse pack, RV w/ reverse pack x 2.

It would be great if one could save notes / comments on a specific breath hold performance after completion. Eg “aborted because cat jumped on me” or “breath up technique changes from X to Y” or “with packing / without” etc. in general l thanks for building a super useful platform!

Right now we can only see last 3 pb's history, unless you go scroll month after month. Personally last3 is not very usefull. Ive been using the app for 4months and would like to be able to see the pb evolution from the 1st to the last pb plotted on a timescale? Would give a bigger view of how progress is going over months/years and if training needs to be adapted.

the AIDA rules countdown are as follows: 2’00, 1’30, 1’00, 30’’, 20’’, 10’’, 5’’, 4’’, 3’’, 2’’ 1’’, official top. Your countdown is missing the 1'30 mark. Request to add it :)

Hi. I would like a few more options For example the voice countdown: 1 minute, 30 secs, 0, 5,4,3,2,1 I find really jarring. I would like the option to disable it. As an example to make the options clearer: Voice countdown on breath Voice countdown on hold Voice on breath Voice on hold Beep on breath Beep on hold Buzz on breath Buzz on hold Buzz at # seconds left breath Buzz at # seconds left hold You could display them as [beep/buzz/voice] on [initiate breath/countdown breath/seconds left] With a plus icon to add another sound in a given set. And a minus to remove. I should add currently I have 'Countdown in rest off' but still here the 1 minute/30 second voice

Please make it possible to sort tables - whether a manual sort, or by name, or by type, or by last used.
