I’m 32 and tracked my fiber for a week mostly out of curiosity.

I was getting like 12g a day.

The recommendation is 25–35g, which honestly explained a lot. I always had mid-afternoon crashes, bloating, and just random stomach stuff I never really thought about.

The tracking apps I tried didn’t really help either. MyFitnessPal tracks fiber, but it’s buried behind calories and macros. Cronometer felt way too detailed for what I wanted.

I basically just wanted an app that told me one thing:

Did I hit my fiber today or not?

So I built one.

It has a daily ring for your fiber goal, barcode scanner, 200+ USDA foods, and a plant diversity score. That last part was kind of surprising to me. A lot of gut health research points to variety per week, not just total grams.

A few honest surprises after using it for ~6 months:

  • Getting to 30g isn’t that hard once you realize where fiber actually comes from. Beans, oats, raspberries, chia, avocado, etc.
  • Plant diversity was harder for me than the actual fiber goal.
  • A lot of packaged “high fiber” foods are not as useful as they make themselves sound.

Free, iOS only, on device, no account.

Would genuinely love feedback on the food database or anything that feels off.

App for tracking all of my hobbies?

Hi everyone,

Sorry, long text:

I’m on the hunt for the perfect app for me, but somehow it doesn’t seem to exist… or does it?

I’m someone with loads of hobbies and interests.
These include video games, books, crochet, diamond painting, jigsaw puzzles, building blocks, book nook crafts and so on and so forth...

Unfortunately, I’m also the type of person who ‘out of sight, out of mind’, and sometimes I can’t even remember what I already own. Or if I start a jigsaw puzzle, don’t get round to it for a while and it ends up under the bed, I forget that there’s a half-finished jigsaw gathering dust there.

For my video games I use the ‘How Long To Beat’ app and for my books the ‘Book Tracker’ and ‘READO’, but for everything else I’ve got nothing.

The app that comes closest to what I want is ‘My Hobby Things’, but a) it’s buggy, b) it’s not aesthetically pleasing and the design is so boring, and c) the app has been abandoned. There hasn’t been an update for years.

I’d like a simple, attractive app with pleasant colours, where I have a ‘Building Blocks’ category and can add a photo of all my sets. And I’d like to be able to view them clearly and attractively, just like in my games and books apps. I’d like to be able to set a status to indicate whether I’ve started the project or not. And perhaps a wish list for projects I don’t yet own.

Sometimes I can’t decide what to do, and on READO there’s a dice that chooses for me A random book. I’d love to see that in the app too. Ideally with the option to choose whether to pick randomly from all categories or just from, say, the crochet projects.

I realise I could probably achieve something similar with Notion, but I’ve tried it and it completely overwhelmed me, so I’d much prefer a normal app.

I’ve been looking for ages, but I just can’t find anything suitable. Does anyone have any ideas?

I thought I wasn’t spending much… until I tracked everything

One day I checked my bank balance and genuinely had no idea where the money went 💀

Food?
Random online payments?
“Small” expenses?
No clue.

That’s when I realized most of us don’t actually track money consistently because manual expense tracking is annoying.

So I built Aarthik.

It automatically reads transaction SMS messages and manages expenses for you.

And honestly… seeing your real spending habits is scary

You think:
“I don’t spend that much.”

Then the app shows:

  • food delivery attacks
  • useless impulse buys
  • subscriptions you forgot existed
  • those “just 200 rupees” purchases adding up

The painful part?
Most people won’t realize this until they’re already broke at the end of the month.

The smart ones start tracking early.

Do you spend more time deciding rather than eating?

Me too 😅

Me and my boyfriend created this app called What2Munch and the name says pretty much everything. It gives you recommendations for food places near you and you can order them on Wolt.

We plan to add other options in the future depending on the feedback we receive.

We would very much appreciate feedback, criticism included.

ps. I hope i’m not breaking any rules since this was developed yesterday and is not promoting, advertising or anything similar from your clicks 🤞

Thank you community! 🍔

One thing I noticed while analyzing products with low retention:

Most users don’t leave because your product is bad.
They leave because the behavior never becomes natural.

A lot of apps focus heavily on features, dashboards, AI, automations, redesigns…

But users are silently asking:

“Is this easy enough to continue tomorrow?”

That’s where most products fail.

Some common patterns:

  • Users sign up but feel overwhelmed immediately
  • The first win takes too long
  • There’s no emotional reward after taking action
  • The product solves a problem, but not frequently enough
  • Users need motivation every time they return

And eventually the app becomes:
“Interesting… but not part of my routine.”

Retention is rarely a marketing problem.
Most of the time it’s a behavior design problem.

The best products usually do 3 things really well:

• Reduce friction
• Create small quick wins
• Give users a reason to come back naturally

Sometimes even a tiny change in onboarding, reminders, progress visibility, or timing can completely change retention.

Curious — what retention problem are you currently facing in your app?

Everything you wanted to save for later

I constantly take screenshots while scrolling social media and browsing the internet just to save something for later: Amazon products, recipes, Reddit posts, funny comments, memes… But it all turns into dead weight, and in 99% of cases I never come back to those screenshots.

Idea: build an app where you can share a screenshot, and the app automatically organizes everything - puts screenshots into the right folders, adds relevant metadata, and makes them searchable later with natural language queries like:
“that Reddit post about an event I saved last week” or “all the movies I wanted to watch”.

what app idea gets copied instantly these days

lowkey any app that

  • gets traction on twitter
  • trends on tiktok
  • hits product hunt
  • or goes viral on reddit 💀

suddenly gets
17 clones
24 wrappers
and 50 “better alternatives” 😅

especially in categories like
• AI tools
• productivity apps
• note taking
• image generators
• chrome extensions
• creator tools 😭

because honestly…
building software became WAY easier now 💀

the hard part is no longer
coding the app

it’s:
distribution
retention
brand
community
and trust 👀

feels like features get copied in
days

sometimes HOURS 😭

which is why lowkey the strongest moat today is often:

  • audience
  • workflow integration
  • user habits
  • data
  • distribution 😅

not just:
“having the idea first” 💀

funny thing is many cloned apps still fail because
copying features ≠ copying momentum 😭

what app category do you think gets copied the fastest rn 👀

Uber for new connections

Idea
An app where you can 24/7 find a person available to meet you and spend time together IRL. And that person wants the same. Like a marketplace.

Issue
Foreigners, tourists, transplants or even introverts know how it can be hard to find the right person IRL (e.g. NYC) to spend time together: visit a museum, eat pizza, check bars, play games, watch a movie etc. Not to build friendship right away (it requires much more time), but LITERALLY spend time together when time is right for you (not in 10-30d) and for other person according to your expectations.

Current options

  1. Meetups - yes, but you have to find those meetups first (hobbies or activities), visit 3-10 events to find your 'city buddy'. Not the right-away option.
  2. GYM and other places - yer, but you have to visit such places frequently. Same story as above.
  3. Mobile apps for friends - one of the most popular is in the same-gender mode and you have to spam to find someone.
  4. Work - yes, if you have a job (onsite/hybrid) in 2026, but still your colleagues should be okay to hang out with you in the city.
  5. FB - not great for that anymore or I couldn't find such groups, mostly they invite to a party.
  6. Reddit - you can post any request in specific subreddits, but honestly, the success rate is gonna be low in general.

Example
You entered the app, create a post what you want/ready to do in your city, specify preferences, post and wait. Other users can send a request. You decide who fits your expectations and respond. Profile is required. And then meet IRL after a short intro upfront (video calls, basic intro, etc to avoid any fake users).

I would help to build this app and test it in NYC.

P.S. If you have the right example (very similar app) please share the name.

We’ve built an AI bot for mental clarity, not sure if it’s actually valuable yet, need honest feedback

We’ve been experimenting with an idea for a voice-based AI focused more on reflection and mental clarity than productivity.

The idea is pretty simple:
A space where someone can think out loud, vent, process thoughts, and hopefully leave feeling a bit more clear-headed.

But while building it, one thing keeps bothering me:

A lot of AI apps feel interesting for a few days, then eventually get forgotten or uninstalled.

So I’m trying to understand something deeper:

What actually gives an AI app lasting value instead of short-term novelty?

More specifically:

  1. What would make an AI companion/reflection app worth paying for monthly, if anything?
  2. What features or experiences would genuinely make you keep coming back over time?

Could be anything:
better memory, emotional intelligence, personalization, journaling, mood tracking, deeper conversations, progress tracking, voice realism, or something completely different.

And honestly, “nothing would make me pay for this” is completely valid feedback too.

I’m mainly trying to understand where people think these kinds of apps succeed or fail long term, because right now most seem to lose users after the initial curiosity wears off.

Thinking of building an app

So I’ve been thinking of building an app but I wanted to get some ideas of what people actually want in an app and would be even willing to pay for. The App Store is full of apps from health to mindfulness and more but not all are actually worth your while, so if you’ve an idea and haven’t found something like it please I would love if people could share !

what app type struggles most after the first month?

feels like some apps are REALLY good at

  • getting installs
  • getting attention
  • getting people to try them once 💀

but keeping users long term?
completely different story 😅

personally feels like apps built around

  • novelty
  • aesthetics
  • “wow this is cool”
  • quick entertainment

usually struggle hardest after the first few weeks

especially
• AI photo/avatar apps
• random productivity apps
• generic AI writers
• habit trackers
• chrome extensions
• “second brain” tools

because once the excitement fades…
users start asking:

“do i actually need this in my daily life?” 👀

and if the answer becomes:
“not really”

they disappear fast 😭

lowkey the strongest apps usually solve:
boring recurring pain

not just:
temporary curiosity

that’s why ugly workflow software sometimes keeps users for YEARS while flashy apps get deleted in a month 💀

what app category do you think struggles hardest after the first month rn?

so my sister was complaining the other day about how every ovulation app she uses is basically an ad-machine that looks like a 2005 spreadsheet covered in pink flowers.

i'm a dev so i spent some time building her a cleaner version called Bloom. it’s 100% local (no accounts/servers) and zero ads. just tried to keep the UI super minimal and actually usable.

i’m trying to figure out if it’s actually good or if i'm just biased since i made it lol. would love some brutal feedback on:

  • is the UI actually clean or just too basic?
  • does it feel snappy on your phone?
  • what features am i missing that would make this a "must-have"?

thanks in advance, be as harsh as you want i can take it.

Feedback on an idea: Location-based alarm for commuters (AlarMap)

The Problem: I have a long commute, and I love to nap. However, I’m always paranoid about missing my stop. Time-based alarms don't work because traffic or train delays are unpredictable.

The Solution: A simple app concept that wakes you up by distance, not time. You set your destination on the map, set an alert radius (e.g., wake me up 1km before), and nap peacefully. The alarm rings when you enter the radius.

Core Features Concept:

Multiple Alarms: Set up different location alarms for different destinations at the same time.

Repeating Alarms: Perfect for a daily commute, just set it once and let it run every day.

Custom Notes: Add specific notes to alarms (e.g., "Transfer to the red line here!").

What do you think about this concept? Do you see any major edge cases or technical limitations (like battery consumption or GPS accuracy in tunnels) that should be considered for this kind of feature set? Would you use it?

Idea💡--> Notes Can become Budgets. Bringing the simplest way of Budgeting to digital world!

Most expense trackers ask you to behave like an accountant.

BudgetNotes was built around a different question:

“What if budgeting felt as natural as jotting something down in a notebook?”

So instead of filling forms, selecting categories, pressing save buttons and managing complicated dashboards…

you simply write:

15 Potatoes
50 Bananas
40 Onions
30 Chocolates

That’s it.

BudgetNotes quietly converts that note into:

• Expense Lists
• Pie Charts
• Spending Distribution
• Inline Bar Visualizations
• Ranked Expenses
• Coaching Insights

from the same note you casually wrote in 15 seconds.

BudgetNotes lets your thoughts live beside your expenses.

Almost like a financial journal instead of a cold tracker.

The app recently launched on Android.

No subscriptions.
One-time affordable lifetime unlock.

i think i spent more time organizing tasks than actually doing them

so i had this realization last month. i was sitting in front of my laptop at 11pm and had spent maybe 4 hours organizing my notion workspace. moving tasks between boards, color coding tags, rearranging my "weekly review" template. you know the drill. looked at my actual completed tasks for the day and it was like... two things. both of them were "organize notion"

started tracking it out of morbid curiosity. over 3 weeks i averaged about 45 minutes a day just managing my productivity system. setting up new apps, importing data, watching youtube videos about other peoples workflows, tweaking templates. 45 minutes per day for 21 days. thats almost 16 hours of meta-productivity that produced zero actual output

and the worst part is i KNEW i was doing it. like i was fully aware that i was procrastinating by making my procrastination system more efficient. tried todoist, ticktick, notion, apple reminders, obsidian for like 3 days, some random open source thing i found on github at 2am. the cycle was always the same - new app, honeymoon phase, spend a weekend setting it up perfectly, 2 weeks later im bored and browsing reddit for the next recommendation

eventually i just said screw it and tried this gamified task tracker called beedone where tasks are just quests and you get xp for finishing them. fully expected to hate it because it has basically zero setup. no templates, no boards, no color coding. you just add a task and do it and get dumb points. and honestly thats exactly what i needed because i cant procrastinate by optimizing a system that doesnt let me optimize anything

not saying its perfect or that gamification is some magic fix. i still have bad weeks. but at least im not spending saturdays rearranging notion databases anymore

idk is this just me or has anyone else realized they were basically using productivity apps as a fancy form of procrastination
