u/behzodhalil

so I've been building this fitness app called Better for the past year and finally feel good enough about it to share

it basically combines workout tracking and nutrition logging into one app because I was tired of using Hevy and MFP separately. 300+ exercises, PR detection, macro tracking, progress charts, works on both Android and iOS (built it with Kotlin Multiplatform which was... an experience lol)

I know getting reviews as a solo dev is rough so I'm down to review yours too. drop your app below and I'll check it out today, leave an honest review

mine: https://play.google.com/store/apps/details?id=io.behzodhalil.better

been working on this for a while now and figured it was time to share

I track both workouts and food pretty religiously but it always bugged me that no single app does both well. Hevy is great for lifting, MFP is great for calories, but I don't want two apps just to see if my protein intake is actually helping my bench press go up

so I built Better - a fitness + nutrition tracker that does both. Android and iOS from a single codebase using Kotlin Multiplatform which was honestly a massive learning experience on its own

the workout side has 300+ exercises, templates, PR detection, and it shows what you did last session so you're not guessing. nutrition side pulls from Open Food Facts, tracks macros, TDEE calculator built in. also body weight tracking with a trend line and streak tracking because apparently I'm motivated by not breaking streaks lol

just shipped progress charts this week - volume and calorie trends over 30/90/365 days. also photo meal logging and localization for Korean, Russian, Uzbek

things that still suck: no barcode scanner yet, I'm one person, design could use work in places. free rn, when I add premium later it'll be $3.99/mo for new features only — everything already there stays free

if anyone has questions about KMM or building a fitness app solo happy to chat

Just pushed v0.3.0 of Better, my solo-dev fitness + nutrition app built with Kotlin Multiplatform (single codebase, Android + iOS). The headline feature: point your camera at a meal, get instant calorie and macro logging.

I want to share the honest build retrospective because the gap between "working prototype" and "shippable product" was bigger than anything I've experienced.

The problem that drove this feature:

Every single beta tester gave me the same feedback: "Workout tracking is great. Nutrition logging is too slow to stick with." Manual food search takes 2-3 minutes per meal. Nobody does that 3 times a day, every day. People would track workouts religiously but abandon nutrition after a week.

Photo detection was the obvious answer. Making it reliable was not.

Timeline vs. expectations:

• Day 1-2: Working prototype. Clear photo of a single food item on a white plate, good lighting. Nailed it. I thought I was 80% done.
• Week 1-3: Reality check. Blurry photos. Dim restaurant lighting. Plates with 6 different items touching each other. Home-cooked Central Asian food that no Western-trained model has ever seen. Street food wrapped in paper. I was maybe 30% done.
• Week 3-5: Portion estimation. This is the genuinely hard part that nobody talks about. Identifying "rice" vs "pasta" is relatively easy. Estimating whether it's 150g or 250g of rice from a 2D image is a different problem entirely.

60% of total dev time went into edge cases that cover about 30% of real-world usage. But that 30% is the difference between a demo you show investors and a product users actually trust.

Architecture decisions (for the technical folks):

• Camera capture is platform-specific (CameraX on Android, AVFoundation on iOS) - this is one of the few places where expect/actual beats interface + DI
• Detection pipeline lives in shared commonMain - both platforms get identical behavior
• On-device processing where possible, server fallback for complex multi-item plates
• State machine: Idle -> Capturing -> Analyzing -> Results -> Error, modeled as sealed interface with a Molecule presenter managing the flow

85% shared code across platforms. KMP genuinely lets you build like a team of 5 while being a team of 1.

Business model context:

Better is $3.99/month. Everything currently in the app stays free forever. Photo detection is included free right now because I want the data flywheel - more photos logged means better detection accuracy over time. I will never paywall existing features. Only genuinely new stuff goes premium.

Revenue: pre-revenue. Still focused on building the product and acquiring early users. Not optimizing for money yet.

What actually matters long-term:

Photo detection isn't the moat. It's the enabler.

Better owns both workout AND nutrition data. When nutrition logging becomes effortless, people actually do it consistently. And consistent data from both domains unlocks something no competitor can build: "Your bench press improved 12% during weeks you hit your protein target."

MyFitnessPal has nutrition. Hevy has workouts. Neither can connect the two. That's the bet.

Biggest lesson from this feature:

The demo is never the product. If you're building anything with AI/ML, multiply your timeline estimate by 3x. The happy path works fast. The edge cases are where you actually earn user trust. And user trust is the only thing that matters for retention.

Question for other builders: What's the hardest "last mile" problem you've hit shipping an AI-powered feature? I'm curious whether the pattern of "60% of time on 30% of cases" is universal or if I just scoped poorly.

I eat a lot of home-cooked stuff - soups, stews, things my mom makes. Trying to log that in most apps is painful. You search for "shurpa" or "plov" and get zero results. Then you're stuck manually entering every ingredient and guessing weights.

Been testing this app called Better that lets you just take a photo of your plate. It breaks down each item separately - the soup, the bread, even the garlic on the side - with weight estimates and full macros.

I snapped a pic of dinner last night and it pulled up the soup at 500g, 375 cals, 30g protein. The bread, the herbs, everything listed out. Took about 3 seconds vs the 5 minutes I used to spend typing stuff in.

It also does workout tracking in the same app which is nice because I was using two separate apps before.

Still in testing right now so not widely available yet but DM me if you want to try it.

Curious though - do most of you even bother logging food? Or is it just too annoying to stick with?

I've been building a workout + nutrition tracking app for the past few months (Kotlin Multiplatform, targeting Android and iOS). Just shipped v0.2.0 to Google Play closed testing last week.

The core idea: one app that does both workout logging and food tracking. Right now if you want both, you're juggling MyFitnessPal and Hevy (or Strong). I want to kill thaT friction.

Problem is - I have no audience. Zero. The app works, closed testers seem to like it, but I'm stuck on what to do next for distribution.

Options I'm weighing:

1. Content marketing - post workout tips, nutrition breakdowns in fitness subreddits. Not promoting anything, just building credibility over weeks/months before ever mentioning the app.
2. Cold outreach in niche communities - find Discord servers, Facebook groups, smaller fitness forums. Offer free access, collect feedback.
3. ProductHunt-style launch - wait until I have a polished landing page and go for a big bang moment.

I'm leaning toward option 1 because it feels the most sustainable, but it's slow. And I'm not sure fitness Reddit even notices usernames enough for credibility to compound.

Has anyone here specifically done user acquisition in the health/fitness space? What actually moved the needle early on before you had any social proof or reviews?

Better is a fitness app that tracks both your workouts and your food. No more paying for two separate apps or copy-pasting between them.

Why I made it: I wanted to see if my bench press improved during weeks I actually hit my protein target. No app could tell me that because workout apps don't know your nutrition, and nutrition apps don't know your lifts. Better has both.

What's included (all free):

• Exercise library (300+), custom templates, set/rep/weight logging
• Food search (2.4M items), calorie and macro tracking, quick-add
• PR celebrations, streak tracking, body weight with trend line
• Offline support — logs everything without cell signal

Hey all. Just launched Better on Google Play. It combines workout tracking and nutrition logging — most apps only do one or the other.

What's included (all free, no paywall):

• Workout logging with PR detection
• Nutrition tracking with 2.4M food database
• Calorie/macro goals, body weight trends, streaks
• Works offline

Future premium features will be $4.99/mo but everything currently in the app stays free permanently.

Quick background: I track both my lifts and my food. That means Hevy for workouts and MyFitnessPal for nutrition. Two apps, two subscriptions, and they know nothing about each other.

I spent 2 months building Better to fix this. It launched on Google Play last week and I have a grand total of 5 installs. But it works and I'm proud of it.

What you get today — all free, no paywall on existing features:

• Full workout logging — exercises, sets, reps, weight, rest timer, templates, PR detection
• Full nutrition logging — food search, calorie and macro tracking, quick-add, custom foods
• One dashboard that shows both your training and eating for the day
• Offline-first so it works anywhere including that basement gym with no signal
• Streak tracking to keep you consistent

Built solo with Kotlin Multiplatform (85% shared code), so iOS is on the way. The $4.99/mo premium tier is reserved for future features only — early adopters keep everything free.

Would love feedback from anyone who currently juggles multiple fitness apps. What would convince you to consolidate into one?

I track my workouts religiously. I also track my food. The problem: every workout app ignores nutrition and every nutrition app ignores workouts. Two apps, two accounts, zero correlation between the data.

I wanted to see "does my bench press improve during weeks I hit my protein targets?" — impossible when your data lives in two separate apps.

So I built Better.

Workout side:

- Full workout logging (exercises, sets, reps, weight, rest timer)

- 300+ exercise library with muscle group tags

- PR detection — weight, volume, estimated 1RM

- Templates — save routines, load in one tap

- "Last time" display on every exercise

Nutrition side:

- Food search via Open Food Facts database

- Daily calorie and macro tracking

- Built-in TDEE calculator

- Quick-add calories, custom food entry

Other:

- Home dashboard pulling workout + nutrition + streaks together

- Body weight tracking with trend line

- Full offline support

- No ads

Built solo with Kotlin Multiplatform — single codebase for Android and iOS.

Would love feedback on the concept.

Just launched Better on Google Play — a fitness app that tracks both workouts and nutrition. Wanted to share some KMP lessons from shipping to production.

Stack: KMP with Compose Multiplatform, Molecule presenters, Decompose navigation, SQLDelight, Koin, Ktor backend.

Key learnings:

1. 85% code sharing is real — but the last 15% is where the pain is. Platform-specific APIs (notifications, file system, camera) need careful expect/actual or interface+DI design. I went with interface+Koin for most cases, only using expect/actual when absolutely necessary.
2. Molecule presenters are excellent — Cash App's Molecule library made state management truly platform-agnostic. Presenters are pure Kotlin, testable without Android framework, and the StateFlow output works naturally with Compose.
3. Decompose navigation survived production — I was nervous about using Decompose instead of Jetpack Navigation, but it's been solid. ChildStack for screen nav, ChildSlot for bottom sheets, all serializable configs. The key gotcha: unique keys for multiple childSlot calls, or you get runtime crashes.
4. SQLDelight offline-first — workouts are logged locally first, synced later. Idempotency keys prevent duplicates. This pattern worked well but conflict resolution logic is complex.
5. Open Food Facts API integration — debounced search against 2.4M+ foods. The API is free but data quality varies. Built a caching layer and frequent-foods suggestions to minimize API calls.

https://play.google.com/store/apps/details?id=io.behzodhalil.better

The app has 300+ exercises, full macro tracking, PR detection, workout templates, and streak tracking. iOS dropping this week using the same codebase.

Happy to dive deeper into any of these areas if anyone's interested.

Hey everyone. After months of building in public, Better is officially live on Google Play today.

The idea is simple: every fitness app makes you choose between tracking workouts (Hevy, Strong) or tracking food (MyFitnessPal). But your body doesn't separate these — your nutrition directly impacts your performance in the gym. So I built one app that handles both.

What's inside:

• Workout logging with 300+ exercises, sets, reps, weight tracking
• Full nutrition logging with a 2.4M+ food database (Open Food Facts)
• PR detection — the app automatically detects personal records for weight, volume, and estimated 1RM
• Workout templates — save and reuse your routines
• Calorie and macro tracking with daily goals (TDEE calculator built in)
• Streak tracking to keep you consistent
• Body weight tracking with trend lines
• Full offline support

Tech stack for the curious: Kotlin Multiplatform with 85% shared code between Android and iOS. Jetpack Compose for UI, Molecule for presenters, Decompose for navigation, SQLDelight for local DB, Ktor backend. iOS is coming this week.

I'd love feedback from anyone who lifts and tracks food. What's missing? What would make you switch from your current setup?
