Products that do what MTOR – A free, local-first PWA to automate workout progression does
Hi HN, My motivation for this came from frustration with existing workout trackers. Most felt clunky, hid core features like performance graphs behind a paywall, or forced a native app download. A few people close to me who take their training seriously shared the same sentiment, so I decided to build my own. I'm working on mTOR, a free, science-based workout tracker I built to automate progressive overload. It's a local-first PWA that works completely offline, syncs encrypted between your devices using passwordless passkeys, and allows for plan sharing via a simple link. The core idea is to…

After decades of tracking my exercise programs in progressively more complex spreadsheets I eventually burned out on metrics and complicated periodization programs to the point where I had almost stopped exercising. I am now at a place where I simply want the minimal amount of structure and tracking to make sure I can maintain my fitness, so I boiled the entire concept down to what I felt was its essence: enough information and structure to remind you of what is needed today, and how it went on the same exercises last week. To reduce friction, the interface is kept as simple as possible.…

Hello, For quite some time, I've been unsatisfied with the built-in timers on both Android and iOS; especially for workouts, when I needed to set up a configurable number of series with rest periods in between. That's when I started thinking about building something myself. It was just a timer and I said to myself "how hard could it be?", I had no idea. The first iteration of the project worked "just fine", but the UI was an eyesore (even more than it is now), and the UX was quite awful as well. As you can probably guess, I'm not versed in design or front-end development. In fact, my last…

I am a software developer and in the last few months after recently becoming a father I was barely finding time for a proper workout. Recently I was reading about new research on Snack Exercises and how beneficial mini workouts of less than 2mins every so often, during the day are to our body. So, I decided to build an iOS App for me and others to help with this. The app generates a list of exercises that I need to tick to complete daily or loose my streak. The algorithm takes into account muscle groups and balancing the exercises to hit most main muscles. I also stayed going through all…

I made a weightlifting tracker app specifically for coders. In weightlifting, progressive overload is one of the most important parts of gaining muscle. You should constantly increase weights, reps, use different set schemes, and that will make your muscles grow. There're many weightlifting programs, using various overloading schemes - linear increasing of weights, some periodic ladder-up increase, switching to different set schemes in case of failures, etc. You can implement all of that in Liftosaur. It works this way: each exercise may define a bunch of variables, that could be changed…

Hey HN, I’ve built and bootstrapped PARIAN. It designs personalized workouts so you reach your fitness goal quickly and efficiently. By training only with goal-specific exercises tailored to your experience level and preferred equipment (or just bodyweight), you skip the wasted time, effort, and disappointment. No more doom scrolling exercises, being overwhelmed by how to plan them, and being bombarded by noise from all the fitfluencers. You workout with confidence knowing each exercise is intentional and each session is moving you forward. Plus, you have the freedom to customize your…

Hi HN community, As a busy techie with kids and other family obligations and my recent health diagnosis, I wanted an efficient way to integrate workouts in my daily routine and my research indicated that HIIT/Tabata style routines fit that requirement much better than a dedicated long running/planned workout routine. I made a simple PWA to help me with that endeavor that I have found useful and hoping some of you may like it as well. No sign ups needed but you can sign in if you'd like to save custom presets and history/progress. You may also enjoy some of the fitness…

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall (€4/month!) → launched it → and yeah… no one cared. zero feedback. zero users. just code in the void. i recently made the whole thing free. not trying to “sell” anything now — just seeing if it’s actually useful, and listening this time. curious how others handle this. ever build…

I got tired of posting on r/fitness and getting unclear feedback, so I built an app that analyzes physique photos with AI. It started as a weekend project after I couldn't get good advice on my lifting progress. Upload a few pics and the AI tells you: Where you rank compared to others (using a gaming-style tier system) Scores for each muscle group with actual numbers Body proportions and balance issues Body fat estimates and body type I also added some fun stuff like matching you to a "warrior type" based on your build (turns out I'm built like a Viking, not the Spartan I was hoping…

I built an app where you LITERALLY have to do push-ups to use Reddit (or whatever app). My guy, this is the summer you get SWOLE! Build a massive chest instead of doomscrolling on Hackernews. Also, it's FREE. You can set it on a schedule. You can set it on a time limit. You can set it after X opens. Or even after you come home from work. The apps will remain blocked until you do your push-ups! The app is built natively on SwiftUI. I use Apple's native Vision API to detect body parts and joints. I use Apple's Screen Time API for app blocking. I don't know what else to say so go on now and get…

Hi HN, I built Axletic, a native iPhone workout tracker focused on making workout logging feel quick and uncomplicated. I drew a lot of inspiration from clean, dark themed apps such as Linear. I felt like a lot of fitness apps out there were too complicated to get started with, messy UI, too many settings etc. This one is made for people that just want to log what they do and understand how it is going. Kinda like a notes app for workout tracking. The core idea is that recording a workout should not interrupt the workout. Axletic lets you log weight, reps, duration, distance, rest periods,…

I've just launched this little iOS app as an alternative to Apple Fitness, which is cluttered and chaotic when it comes to visualizing basic workout stats and metrics. The idea is to focus on a clean, minimalistic design and only show high-level metrics that are actually useful, e.g. how often did I work out this week/month/year, cardio vs strength vs mobility, surf session count in February, etc. It's free and offline. Also, no signup, no ads, no data sharing, no social feeds, and no notifications. Just open it and get a quick glance at the state of your workout game within 2s.…
