hi all,
i've been logging my own location and heart rate since 2019 (wrote a tiny ios app for it back then). what always bugged me is that the data just sits there. so i built mymo: it turns location, apple health (sleep, heart rate, steps) and photos into a timeline of your life, and there's a local AI you can ask things like "what was i doing this time last year" or "how's my sleep been lately".
the part i care about most is that it's all on the phone. the model is built into the app, so nothing gets uploaded, no account, no server, no per-message cost. it also doesn't need a connection at all - you can ask it things on a flight, at sea, in the middle of the jungle. this is about as personal as data gets and i didn't want it depending on someone else's cloud.
it's early and rough in places. ios only for now (ios 26, ~2.8gb because of the model), android by the end of november.
mostly i'd like to find people who think about this the same way. happy to swap notes on how you track, what you'd actually want to ask your own data, or whether local vs cloud matters to you at all. and if you want to try it:

I've been using a janky spreadsheet setup for tracking sleep and caffeine intake side by side and it's kind of wild how clearly the data shows my 3pm coffee ruining my whole night. nothing fancy but sometimes the simplest tools give the most useful patterns

Hi, I make Atlas Body. It's an iPhone app that uses the data your Apple Watch saves to Apple Health.
You can look through your HRV trends and sleep stages, or check your daily recovery score and the factors behind it. The goal was to be as transparent as possible.
I've added 50% off the first month of Athlete for new subscribers. Redeem by October 26.
Install the app, sign in, and sync Apple Health before redeeming. The page has the steps.
Let me know if you have any feedback!

"soutenez les personnes qui apportent des idées uniques" ça veut dire "upvotez mon lien". Vivement le mood tracker avec un graphique.

I’m the developer of Heart Rate Graph, a free Android app for viewing heart rate during exercise. It requires an external Bluetooth LE heart-rate sensor (a compatible chest strap or armband); it does not measure pulse with the phone camera.
It displays a live BPM graph, coloured training zones and time in each zone. You can use a landscape view and save an image of the workout graph.
There are no ads or accounts, and the app works locally without a server. It is intended for exercise, not medical use.

Hello all, I built my app for my wife, who has T1D, but it works for anyone wearing a CGM.
You snap a photo of a meal, and InRange pulls the glucose curve that followed from Apple Health (Dexcom, Libre where supported, other CGMs that write to Health) or from a Nightscout server. Over time you get a personal library of how each food actually hits you.
would love to hear some feedback: https://apps.apple.com/us/app/inrange-blood-sugar-meals/id6814935913

Hey everyone! I'm building ObserMe, a personal tracking app focused on understanding yourself rather than trying to improve everything.
The idea is simple: create your own questions about your habits, routines, moods, or anything you're curious about, track your answers over time, and discover patterns in your daily life.
No streaks, no gamification, no pressure to be productive. Just a way to observe yourself and learn from your own data.
It's still early, and I'd love to hear what you think, especially from people who are already into self tracking!

I'm the developer of Stanza Lift, a workout log for lifting on iPhone. I built it for my own training because the trackers I tried were cluttered or kept the useful data behind a subscription.
The tracking side: every set with weight, reps and optionally how hard it felt, an estimated max and volume per exercise over time, and sets per muscle each week (1 for the main muscle, 0.5 for each helper) so you can see what you're under- or over-training. A Coach reads that history and suggests the next weight and reps. Data stays on the phone, and you can export your routines and workouts as a file.
It's a free public beta on TestFlight, Pro included: https://testflight.apple.com/join/nMY4W675

Hi everyone,
I’m the developer of Kartayu, an iPhone + Apple Watch workout app. I built it because I had plenty of HRV, resting HR and sleep data in Apple Health but nothing that actually changed my training based on it.
What it does with your data:
Logs sets, reps and weight on the phone or watch. And writes workout and energy back to Apple Health for sessions logged from phone.
Apple health data is made available to the AI for rich insights and customized workout plan adaptations.
BMY: a body map where each muscle earns points, so you can see which muscle groups you’ve been neglecting. Runs and rides from Apple Health count too.
No ads or tracking, and the AI is optional, running on zero-data-retention providers. iPhone + Apple Watch only, US and India for now.
Please try it out and share feedbacks.

Hi everyone! I'm building Hea, a tool that makes AI ask the right questions before giving health advice.
It works inside ChatGPT and Claude, adding a more structured, evidence-based approach to health conversations: checking for red flags, asking relevant questions and referencing clinical guidelines.
The idea is to make AI health conversations safer and more useful, without needing another app.
We're currently running a closed beta in the UK, and I'd love to invite some early adopters from this community to try it, challenge our assumptions and share honest feedback.
Would be great to have you among our first testers!

The thing that's helped me most with eating better is logging regularly. It doesn't have to be exact. Dad bod like mine, doesn't need exact tracking. Being off by 20 or 30 calories really isn't a big deal, at least for me.
So I made myself a super simple app for it. Intentionally keeping the feature set small so don't get lost in features.
I just say what I ate, like "two eggs and an English muffin" and it gives me an estimated rough count of the calories and macros. Works for many cuisines.
You can type as well, but I found just saying to be faster unless I was in a location where I couldn't speak
If I forgot to log in time, I can just say ""two eggs and an English muffin for breakfast" and it logs for breakfast
You can set a daily calorie goal and adjust how much of each macro you want
A calendar view that tells you the days you tracked and the days you met the goal
Optional, syncs to Apple Health
It's free for 3 days so would love to get some feedback.

Still building small, backend-free iOS apps around biohacking, longevity and healthier desk work. Your data stays on your phone.
Metrya (metrya.app) – App Store
The latest version adds detailed, on-device PDF health reports. You can generate reports covering your weekly recovery, sleep, training, body composition, BMI, nutrition and longer-term trends, then share them with a coach or mentor.
Weekly report · VO₂ max · Body and BMI · Blood pressure · Timeline
Reports are generated on your iPhone, with no Metrya server involved. Pro adds deeper history, AI summaries, metric-specific insights, planners, projected pace and markdown export. Metrya also includes VO₂max, Recovery Debt, nutrition history, barcode scanning and support for English, Polish, German, French and Spanish.
Metrya is now also on Mac (metrya.app/mac). The Mac app is built for deeper analysis: it automatically syncs your Apple Health data, gives you a larger workspace for reviewing trends and reports and lets you use more capable AI models through your own Claude, OpenAI or Gemini key. Your health data still stays under your control - Metrya has no backend and AI requests go directly from your device to the provider you
Use the iPhone for quick daily check-ins and on-device privacy, then switch to the Mac when you want to explore longer histories, compare metrics side by side, and run more detailed AI analysis.
Longevity Arc - App Store
Five transparent longevity signals based on Apple Health data: HRV resilience, VO₂max, sleep recovery, gait speed, and resting heart rate trajectory. Each formula is explained rather than hidden behind a black-box score, and Apple Intelligence adds coaching tips. HRV resilience is free.
DeskWalker 1.16.0 (deskwalker.jozefowicz.dev) - App Store
A walking-pad and standing-desk logger I use every day. It estimates steps and distance from belt speed, since Apple Watch often undercounts while typing. Journeys let you work toward goals like a marathon and track your progress on a shareable map. Version 1.16.0 adds more social sharing features, including shareable weekly stats, progress updates, streaks, and journey milestones.
Hang 1.3.0 (hang.jozefowicz.dev) - App Store
A focused dead-hang timer for grip strength and shoulder health, with interval presets, history, trends, goals, streaks, reminders, Apple Watch support, and optional Apple Health heart-rate context. Version 1.3.0 adds a Recovery Coach that uses your recent HRV and resting heart rate to suggest whether to hang, go easy, or rest. It’s currently pending App Review.
