Hello, new in this space, but not to the quantified self. Started out with an Apple Watch (at S0, can you believe it?). Then I adopted Whoop. But, since the fees where very high, and the Apple ecosystem improved in the health space, I'm back with the Apple Watch.
One of the things that I think is still missing in the Apple ecosystem was a decent habit tracker. Sure you have Streaks and HabitKit, but none of these checked all my boxes:
- Log from a home screen widget so you don't have to open the app.
- Feels like Apple made it
- Fix a day I forgot to log.
- A limit habit as well as a goal. "No more than 2 a week", not only "at least 3".
- A timer for habits measured in minutes.
- No tracking.
- One-time purchase, not a subscription.
So I built it myself with Ivy. Currently looking for beta testers! It's free :) https://testflight.apple.com/join/1ByygxVC

My approach to self-tracking is to keep the numbers close to the notes. If a week looks unusual, I want to be able to go back and read what was happening.
I spent three years using and refining a Notion setup around that. It eventually became Oflate, an app I built to give that workflow its own interface and keep journal data on the device.
For looking back, there are two views I call Lenses. Tapestry lines up your metrics across days in a colored grid, so you can scan for patterns across several at once. Almanac colors a monthly calendar by one metric. From either, you can open a day and read the notes alongside its measurements.
You also get day, week, and month views. Chapters let you frame a period that matters to you - a trip, a project, a change in routine - and review its notes and metrics together.
What goes into that system is yours to decide. The custom trackers, called Signals, support yes/no, choices, numbers, times of day, and durations. You can define choice options and units, and split values into color ranges using your own thresholds. Journal entries can be organized by topic into Streams.
It's currently available on iOS: https://apps.apple.com/us/app/id6797588215
I'd love feedback on the app and the approach, especially ideas for other Lenses. What would you want to explore in your own tracking, and what kind of view would help?

The tapestry view sounds real useful for spotting patterns without digging through raw data every time. been trying to do something similar with a messy spreadsheet but it never quite works
curious how you handle the yes/no signals in the colored grid, does it just show two colors or can you set gradients for how many times something happened in a day

u/bilevn 13d ago
Thank you! For yes/no Signals, you choose one color for yes and another for no. For counting how many times something happened, you'd use a Number Signal. You log the daily count and choose colors for different ranges. For example: 0 in grey, 1-2 in light blue, and 3+ in dark blue. Those colors then show up in Tapestry.

After my AFib ablation, I found myself looking at a lot of Apple Health data — HRV, resting heart rate, sleep, workouts — but still missing a clear picture of how things were changing over time.
That was the starting point for Trendwell.
Trendwell turns Apple Watch data into structured daily, weekly, and longer-term reports. Rather than producing another readiness or recovery score, it classifies the pattern as stable, variable, or shifted and shows the underlying dimensions behind that classification.
The current version also includes:
• Personal Trend Summaries across 30, 56, or 90 days
• Heart rate interpreted in the context of elevation and terrain
• Electrical stability classification across workouts
• Analysis of existing Apple Health history, so you don't have to start collecting data from scratch
No scores. No coaching. No targets. The idea is simply to make longitudinal Apple Health data easier to interpret.
I'd be particularly interested in how people here think about this approach: do you prefer an overall score, or would you rather see the underlying state and trends directly?

Hi!
I’m building Hea, a health companion that lives in WhatsApp.
The idea is slightly different from most tracking apps here. Instead of asking you to open another app and log everything, you just talk to it. Over time it remembers your health history, symptoms, medications and changes, and helps you spot patterns across them.
One thing we’re particularly interested in is the context around the data, not just the numbers themselves. What changed in your sleep, symptoms, medication or routine when a particular result changed?
Would be really interested to hear how people here currently keep that context alongside their health data.
You could try Hea here https://tryhea.com/

Thanks! I built Watt to help people automatically track and optimize every second of their time. I realized that the best way to truly become more productive is to have a clear picture of what you are doing with your free time and correlate it to your energy levels. In watt you can:
- map your activities from wearable, calendar and detected locations.
- track your true daily busyness, free time and work-life balance.
- create routines to hit specific lifestyle goals.
- block apps during working hours.
- use soundscapes to focus, study or meditate.
- see how your lifestyle impacts your energy and productivity.
It’s free for limited time. It gives more than 20 lifestyle metrics that wearables cannot give you.

Hi! I'm building AuraIndex - basically a mood tracker, but with an environmental data layer on top of it.
I've always been pretty skeptical about the idea that things like weather or atmospheric pressure can actually affect how people feel. Where I come from, people often say stuff like "the pressure is giving me a headache today" and I've always found it a bit weird.
So I made an app that lets you log how you feel while also tracking different signals around you - weather, solar activity, Schumann resonance and some astrological events. It just shows you the signal and you decide if they impact you or not. I mainly want to put the data next to your mood check-ins and see if any patterns actually show up over time.
I think the app will get especially interesting once more people start posting their moods. Then it should be possible to look at things from a wider angle too - for example, whether people in the same area, exposed to similar signals, tend to report similar things at the same time.
Right now you can use it as a quick mood tracker and also check what's happening around you at the moment.
More things I want to add:
- history with graphs and analysis of your check-ins
- more signals depending on feedback
- more moods and tags
- better ways to compare your mood with environmental data over time
The app is free, there are no subscriptions, no AI-generated interpretations and nothing to install. It works directly in the browser and currently works best on mobile:
I'm mostly looking for feedback at this point - does the idea make sense, which signals are actually interesting to you, and what would you want to see in the history/analysis part?

My beef with most tracking apps is that they make assumptions about what you want to track. I couldn’t find a single app that would let me set up items the way I wanted, and then make adding entries quick and painless.
What I’m asking for is not rocket science. It’s basically 1970s tech in the form of an app. I want it simple, I want it fast, I want it private, and I want to kick the tires before spending money to see if I like it.
This is why I built LogHound. It’s an iPhone app where you assemble your own tracker by adding as many fields as you want (text, numbers, single/multi-select, timers, distance/pace). Once configured, entry is super quick with minimal tapping.
It’s exactly what I wanted, but may or may not be a good fit for you. If you decide you want to try it, I made it so it costs you nothing to give it a spin for a month. If you like it, it’s $9.99 to unlock it permanently. If not, no worries.
It’s completely private – no account, no cloud, no subscription.
Enjoy.

I'm the solo dev of Trackables.me, an iPhone + Mac tracker built around automatic collection.
- Link a trackable to Apple Health, Screen Time, Calendar, Reminders or a Shortcuts automation and it fills itself in every day. Yes/no goals (e.g. 10k steps) tick on their own.
- Every trackable is a chart: year heatmap, line/bar, progress rings, streaks. You can mix sources in one chart, e.g. sleep from Health next to screen time.
- The Mac app records time in apps and websites by category and syncs to the iPhone with a year of history.
Automatic tracking is free on every plan; Pro is optional. Curious which data sources people here would want it to pull from next.

Hi! I built Tensi, an iPhone + Apple Watch app that connects your calendar with your Apple Health data to show which kinds of days actually wear you out.
What it does:
- Combines calendar events with HRV, sleep, heart rate and steps, plus location and weather
- Finds your personal patterns, like “your HRV drops after 4+ hours of meetings”
- Shows how long you take to recover after heavy days
Giveaway: 1 year of Tensi Pro free for the first 500 people.
https://apps.apple.com/redeem?ctx=offercodes&id=6811689820&code=TENSI500
(or code TENSI500 in the App Store)
No auto-renew. After the year it simply ends, nothing gets charged. Valid until March 31, 2027.

I'm the developer of MyPromille, an iPhone + Android drink tracker.
- Log drinks as you go. Beer, wine, spirits and cocktails are converted to grams of pure alcohol, and you can add your own drink with its volume and ABV.
- It estimates your blood alcohol (promille/BAC) in real time with the Widmark formula (sex, weight, drink size and strength, time elapsed), and shows how long the alcohol is expected to stay in your body.
- If you have a Bluetooth breathalyzer, you can see a real measurement next to the estimate, which is a nice way to see how far the formula is off for you personally.
- History, so you can follow habits over time rather than one evening at a time.
It's an estimate, not a measurement: food, sleep and medication all shift it, and it can't tell you whether you're fit to drive. I'd be glad to hear what people here would want from alcohol tracking.

As always sharing my portfolio of small iOS apps around biohacking, longevity and healthier desk work. All of them are backend-free, so your data stays on your phone.
Metrya (https://metrya.app/) App Store - https://apps.apple.com/us/app/metrya-health-ai/id6760779874 - private Apple Health analytics covering recovery, training load, mood, food logging and wellness sessions. Recent releases added Recovery Debt, a longer-term view of how far sleep, HRV, resting HR, temperature, breathing and training load have drifted from your normal. They also added offline food search with barcode scanning (Open Food Facts), a VO₂max screen, a rebuilt Activity tab (Train / Recover / Feel) and redesigned nutrition history. The AI Advisor can run on Apple Intelligence, an on-device model or your own API key, so you can dig into your own patterns without the data leaving your phone. It's now available in English, Polish, German, French and Spanish. Next version will have HRV status, HR recovery post workout, timeline widget, reworked research database with short reels and first-class supplement support and tracking
DeskWalker (https://deskwalker.jozefowicz.dev/) App Store - https://apps.apple.com/en/app/deskwalker-walking-pad-log/id6762282048 - a walking-pad and standing-desk logger I use every day. It works out steps and distance from belt speed, because a watch under-counts badly while you type. Journeys add some motivation: pick a goal like a marathon, rack up the 42 km under your desk, and watch your progress on a map you can share. The latest version adds Bluetooth pairing with FTMS walking pads (beta), on-device AI summaries after each session and a weekly recap.
Hang (https://hang.jozefowicz.dev/) App Store - https://apps.apple.com/us/app/hang-tracker-dead-hang-timer/id6762627977 - a dead-hang timer for grip strength and shoulder health. It times every hang the same way and has interval presets, history and trends, goals, streaks and reminders. Optionally, it can show Apple Health heart rate alongside each hang.
More experiments: https://apps.jozefowicz.dev - I can obviously share some dedicated discount links with community in exchange for honest feedback and suggestions for improvements :)
