Is this something that connects to a smartwatch or a bike with sensors or once the activity is done (on the smartwatch, I upload to this, a bit like what can be done with strava
Or is this something that you use to track manually?
Awesome, do you have a github link so folks can install with obtanium? I won't use it until amber integration happens, but this is awesome.
It's a very cool idea! I can't wait to test it... where do we start? Is it ready yet? 😍😍😍😍
Epiiiiic! Will try :110percent:
Can’t wait! Great idea! 💪
Where do I fthe app? app?
Not yet! I’ll get the TestFlight and Zapstore set up soon for people to try. Will let you know 🤙
Thank you. I know it's tough! I am slowing down my open source dev right now because the worky job is picking up steam and as the weather warms up I end up with a dozen farm projects
For now a workout log that you enter the activities in manually. I’d love to integrate fitness tracking data soon though, but it’s just me working on it so I anticipate that will be in a few epochs
This is awesome 👏
Curious to try this! Thanks!
Hey #31days crew - very interested to get your early feedback when I release this. Thinking of some fun #31days leaderboards etc. Are you guys mostly on iOS or Android or both?
Awesome
No code to show though?
#yestr
Found it💪
I’ll use this
@TheWildHustle - would love to hear your thoughts on the Nip proposal. I came up with some ways that it can be extended to log runs too. Were you working on anything for this?
How do I use it?
Great proposal! I haven't looked into developing the run tracking NIP yet, but I'm excited to support interoperability between POWR, RUNSTR, and the rest that are sure to follow. Lookout for my DM 🫡💪
Awesome. I like te idea of Strava, but dislike the privacy implications. This looks like a viable alternative.
Congrats Brother. 🫂
Well pretty much everything you post on a public relay is available, but I’m not planning on kyc-ing any users. Also will hopefully figure out a way to store workouts encrypted eventually so you can backup your health and fitness data privately.
@JeffG is a runner and has put some thought into this. Might want to reach out to him

I use True Coach, and it’s great. but (like most centralised for profit apps, theres a catch), my workouts are locked to my trainer and the trainer needs to willingly pass that history onto another if I leave him. So, incentives could be malaligned upon a bad breakup.
I’d like to see your app satisfy the need for trainers to have a robust backend for workout creation, but allow users to own their data.
Omg, omg, omg!!!!
Very cool. I look forward to this.
This sort of Nostr app has been discussed for a while. I'm super excited to see it coming to life. Hell yeah Doc!

This is fantastic. Well done
@Sebastix is this our Nostr strava app?
Very cool!
Thanks for sharing your experience with True Coach. When I first started working on POWR I was talking about it with
@PABLOF7z and he had the same pain points you’ve highlighted and it’s one of the problems I aimed to solve.
POWR absolutely satisfies the walled garden issue by decentralizing both workout creation and data “ownership”. The POWR Pack functionality (using NIP-51 lists) allows anyone (including trainers) to create and share custom exercises, workouts, and even full programs that clients can import directly.
The key difference with POWR is that your workout data is controlled by YOU, not locked in a trainer's account. Your workout history is tied to your npub via signed workout records regardless of trainer changes. I hope that in the future myself and others interested in the topic will build professional-quality programming tools for trainers and gyms.
I built POWR specifically to address that misalignment of incentives you mentioned. Built on Nostr, both clients and trainers maintain their independence while still being able to collaborate effectively. Sats and nuts 🥜 will flow frictionlessly peer to peer and centralized middlemen like True Coach can be circumvented.
If you have a few minutes please check out the Nip spec that I wrote which lays out the different event kinds. What I’ve built so far is a proof-of-concept that demonstrates this can work. I hope to get POWR to the point where it’s a slick app that anyone will find useful whether they understand the importance of Nostr or not.
When do iOS get that
Also, be sure to ask
@Gigi if data ownership really exists
This needs the recommended routine by
r/bodyweightfitness, as it is something like an open source project. Would be quite a match I think. Let's see if someone is cool enough to implement it 🧡💪💜
This would actually motivate me to be more active...

great work!
can you publish a release so i can download on obtanium/get it published to Zap store?
We need more of this
Next one on my list: Todoist/ticktick equivalent.
I swear I'm bout to hire a developer ad hoc to build this for me

I've never used a fitness app before, but I'll give this a try and hopefully have some feedback on it.
Thanks for putting this together!
Whoa, nice work! Looks pretty polished for not being a dev! 💪
What tools did you use to help build it?
Keep crushing it! Pumped to try the TestFlight when it’s out 👊
Maybe in the future, we need an integration of the GPX data of our recorded workouts.
Interested to dig into this!
@Derek Ross …
My “Tech Stack"
- Three paid versions of Claude 3.7 working in parallel. Claude, Claudia and Claudette. Some custom MCPTools used to query forked local versions of NDK, Olas and the Nostr repo. Thank you
@Gzuuus for turning me onto MCP tools!
- React Native + Expo framework (after many failed attempts)
- Mercilessly bothering
@PABLOF7z @Terry Yiu @JeffG and
@hzrd149 until they answered my questions. Sorry
@hzrd149 - forgot to tag you on the OP but your advice on my nip proposal was extremely helpful!
- NDK and NDK Mobile (with all their quirks and little documentation 🤣)
- Olas as my "good example" of a react native project
- Dangerous amounts of coffee. Giving up stuff like Netflix and coding instead.
- Pure stubbornness when I wanted to smash my computer
- Stack Overflow, YouTube, GitHub.
TestFlight coming soon! Just need to fix a few "minor" issues first. No surprises but it’s more intimidating navigating the stupid fucking App Store than building the app.
we'll def need to do this.
Absolutely love this idea. I have some plans set up for using the proposed nip to be able to handle things like supersets/paired exercises, variations and exercise progressions, rest timers, etc. I think once I have a stable version I’ll try to implement this. Bookmarked 🤙
Holly shit! That’s the app I was looking for!
Cannot wait to try Test Flight!

Android on my end!
I’ve logged about 250 workouts on True Coach. Upon signup, True Coach does not make it clear to clients that data is locked to trainers. My trainer actually told me “True Coach is one of the services I provide”… even though *I* pay for the app, and I’m the one who performed and input those reps—but this is how they think.
Was thinking about how to incentivize trainers to switch to a platform that removes their ability to hold client data hostage.
The answer: Forget them, they are entrenched and massively incentivized. The answer, build a network of ball-sunning bitcoiner trainers by capitalizing on alignment with community ethos.
Best of luck: I can’t wait for POWR to help me get through those dips.
Dude, laughing my ass off right now. Powr, where the ball sunning chads go to train 🤣 But yes… I’m a big believer in V4V. Provide good content and services and with enough of a network effect you should get rewarded. The hard part is bootstrapping the user base here on nostr. Which is why I want this app to be awesome for anyone to use, whether they are new to Nostr or not.
Lets Go !!!!
Currently using flexify, but I look forward to use POWR now
Straight to the
@Zapstore
Well done! Ship ugly, ship often! (Also, it's not even very ugly)
I can't wait to try it out.
It says a lot about how much potential Nostr has when a full-time physician can ship a fully functional (and damn nice looking) app.
Nostr's super power has always been the simplicity and left-curve nature of the spec. GM
@fiatjaf , I see you.
AI is going to supercharge this pattern and we're going to have thousands of apps catering to all sorts of niches.

Interesting.
ignites, a pulsing fire,Muscles coil with raw desire,A workout’s proof, its thunder rolls,Outshines the relay’s fleeting goals.
Relays click, they pass the spark,A fleeting charge through circuits dark,Or runners dash, baton in hand,A fleeting race across the land.
But power builds in steady strain,Through every rep, through every pain,No handoff halts its iron reign,A force no relay can contain.
The wire hums, the signal flies,Yet strength ascends where effort lies,A workout carves what relays chase,Endurance wins the timeless race.
Impressive, bravo!
Wow, physician, smartphone dev and did you also create the catchy song in the intro video? Winning!
Could you add an alt-tag and nip-89 to your kinds? Once you are up and running, i'd also advice to see if you can write a quick 'n dirty npub.pro thingy such that people can display stuff on their webpage.
Yes I’ll submit a kind 31989 soon. Haven’t done it yet bc I was mining the vanity npub for the Powr account. What do you mean by “npub.pro thingy”?
Lol no, that was a stock song from InShot. Glad you liked it though! We’re in the minority. Got some shade for that choice.
🤣 sure id take that award
Npub.pro displays events on a webpage; mean a simple implementation to render your events for those webpages, such that people have a minimal viable way to share their stuff.
I mean, I know what npub.pro does. Aren’t the event kinds and tags that are displayed set by the users? Rendering new event kinds would need to be implemented on the npub.pro side. I also plan on setting up a profile view that shows all of a users workout event records on the Powr app
What the particular npub.pro page looks like is indeed determined by the owner, and yes it would require an implementation on the npub.pro side; a minimal viable render should be fairly easy to write and then you can request
@brugeman to add it is what i am saying :).
Generally implementing a kind in other clients is not your concern, but giving users atleast an option outside of your own client (especially if its the first and therefor only implementation), and in this case a fairly 'universal' one in the form a webpage.
Its not so much about npub.pro specifically, it could be something else as well.
It also is yet another example implementation/render, that developers can have a look at/take inspiration from, especially because its outside of the particular usecase-client context. I.e. 'how would/could i display these exercise things in my not-exercise client'.
are you talking about

Sounds like a fantastic idea. But I’m working on powr alone right now and focused on getting the Android and iOS mvp out first. I’ll keep it in mind though and try to work on something like that in the future once I have a stable version of the app out. Meanwhile, the draft of the spec I wrote is available if you wanted to start to work on something like this. I’m not planning on deviating much from the spec and you could send a pull request to Brugeman. Cheers!

Just let people specify their relay and they can use their own relay for the stuff they want very private.
So private relay > encryption on public relay?
Definitely simpler. I think for POWR it makes perfect sense 😅
How do you stop the constant urge to overcomplicate things?
Reflecting on the fact that everything is 10x harder and takes 100x longer than you’d think
Then the simpler, pragmatic solution becomes all the more attractive.
Almost always the simple solution was the right one all along; just look at nostr vs web3 or DID Rube Goldberg machines
But it’ll never scale! 😭 and how can I make sure my ID is unique and no one is impersonating me?! And who will build the roads?!
This could be really great. Keep working!

Working on it! Also on vacation this week with the fam so trying to disconnect a bit. But soon 🤙
Imagine if Crossfit Open would actually be open.
The apps and communities you can build on top of the shared and open programming.
Our gym uses ChalkitPro for programming and tracking.
- it has lots of data flexibility. Bit the ui is mediocre, ux even a bit worse, and imeven after years of using, I can never find my PRs or other obvious things there.
Biggest pain point:
- workouts are just a single unstructured text fields. You can record and save your score, and if the very same workout shows up in the future, there's easy lookup for your past scores.
- Unfortunately, a single typo or a formatting change in the workout description and the workout is not considered the same, so it's hard to recall your previous scores (weights).
Idea:
- I'd like to see some more intelligent (AI) grouping and pattern matching so that it understands that "4 sets of 5" is the same as "4x5" and similar to "4 x 4-6 reps".
- same for WODs.
- Even use me as a free labor and prompt me to confirm "Is this the same workout?" here and there if necessary
Around here, *every* community can be(come) a workout community.
You just add the content type(s). Done.
Check out the nip proposal I wrote. This nip can cover all of these use cases. Exercises and workouts are completely customizable via a tagging system, and with Nostr they’re reusable, shareable and modifiable. A box could publish a WOD and share it to their customers, create leaderboards, from the results, reward badges, zap, etc. I’m having fun building Powr but I’m even more excited to see what people can build with the spec I wrote.
@TheWildHustle even added some comments showing how it can be used to track runs which is a fantastic use case.

Special thanks to
@Terry Yiu @PABLOF7z @JeffG and
@fiatjaf for their invaluable guidance during my 3-month journey working on POWR. Their support has been essential.
POWR isn't close to what I hope it’ll become (yet), but as Pablo wisely told me: ship early! Look for the TestFlight and Zapstore release early next week, but please have patience with the release and updates… I’m a Nostr enthusiast, not a dev, and working full time as a physician.
Devs: I'd love your feedback on my NIP proposal for workout event kinds, and if you’d like to contribute please reach out!
POWR On! 💪
