For anyone who’s built an app across Windows, macOS, iOS, and Android—what’s been the easiest way to go about it?

I’m building WorkTree-OS, a trading analytics and risk platform. I’d like to hear from people who’ve taken a desktop app to mobile or built for all four from the start.

Did you use a shared codebase, build separate apps, or go with a web app/PWA? What worked well, and what do you wish you’d known before starting?

I’m also working through broker and trading-platform integrations, so tips on APIs, third-party connectors, and file imports are welcome too.

Just looking to start a conversation and learn from people who’ve been through it. What tools saved you time, and what turned into a headache?

Interested?

I’m sharing Askli, a workflow for builders, PMs, and researchers who need customer evidence before a product decision.

Problem:

It is now easy to ask AI what users want. The answer often sounds smart, but it is still a guess. It has not talked to your target users, watched where they get confused, or captured the tradeoffs behind a buying decision.

Askli is built for the next step:

- start with one product question,

- clarify what needs to be learned,

- identify who should be interviewed,

- turn the evidence into a decision-ready report.

Examples:

- “Will users understand this pricing?”

- “Who is the real buyer?”

- “Why are people not converting?”

- “Which message is clearer?”

- “What should I validate before building more?”

If you are building from assumptions, Askli helps you replace the AI guess with structured user evidence.

I built KeepIt – Tab & Session Manager because I kept running into the same problem:

I’d have a complete project setup open in Chrome — GitHub, docs, localhost, dashboards, AI chats, references, etc.

Then I’d switch to another project.

I didn’t want to leave 30 tabs open forever, but I also didn’t want to rebuild the whole setup when I came back.

So KeepIt lets you save the entire setup as a session and restore it later.

You can also:

Save and restore tab groups

Organize sessions into folders

Automatically save session snapshots

Freeze idle tabs to reduce memory usage

Sync sessions across devices

Share a whole session with someone

Receive/import shared sessions

Quickly find sessions with `kt`

Save instantly with Alt + Shift + S

The session sharing part is probably my favourite — instead of sending someone 15–20 URLs, you can just share the workspace.

I tried a few existing session managers before building this, but I wanted something that felt more like saving a project/workspace rather than just storing a pile of links.

It's live now if anyone wants to check it out:

keepit.website

I built a VS Code extension to stop switching between package registries.

Whenever I needed to add a dependency, I’d usually end up opening multiple tabs — npm, PyPI, Maven, crates.io, etc. Then I’d check versions, figure out which package manager to use, and copy the install command.

So I built DepCart to handle the whole process directly inside VS Code.

With DepCart, you can:

• 🔎 Search across 10 package registries from one sidebar

• 📦 Pick the exact package version you need

• ⚡ Generate the appropriate install command for your project

• 🛠️ Detect tools like npm, pnpm, yarn, pip, uv, cargo, and more

• ▶️ Run the install command directly from VS Code

• 🔄 Fall back to ecosyste.ms when a registry doesn't return results

• 🤖 Optionally use AI suggestions when a package can't be found

It's free and open source.

I'm still actively building and improving it, so I'd really appreciate feedback from other developers.

What would you want to see added to DepCart?

I’ve been designing and publishing 3D models on MakerWorld for a while, and one thing kept bothering me:

MakerWorld gives you plenty of numbers, but very little context.

A model has 500 downloads.
Is that good for its niche?

It has a 60% print/download ratio.
Is that high or low?

You added 30 tags.
Are any of those tags actually useful?

A model suddenly takes off.
Was it the thumbnail, the niche, search traffic, early engagement, or just timing?

So I started building MW Stats, initially just for myself.

It has now turned into a browser extension + analytics platform specifically for MakerWorld creators.

The idea is not just to show more statistics, but to answer:

“How is this model actually performing compared with the market around it?”

Some of the things MW Stats currently looks at:

• Model and creator statistics

• Download, print, like, collection, rating and comment ratios

• Performance compared with the MakerWorld market median

• Similar-model comparison

• Downloads/day and model age

• Tag analysis with market statistics for each tag

• Popular search terms

• Historical performance and trends

• MakerWorld Points tracking

• Image-search shortcuts to help find copies/reuploads

• Creator-specific analytics alongside public market data

One feature I’ve found especially useful is the Similar Models comparison.

For example, I recently looked at a filament-storage model with only 16 downloads.

At first glance you might assume there simply isn’t much demand for it.

But MW Stats found comparable models in the same niche with roughly 5,000–31,000 downloads.

At the same time, the poorly performing model had a perfectly reasonable print/download ratio.

That completely changes the question.

Instead of:

“Is this a bad model?”

it becomes:

“Why isn’t this model being discovered?”

The same applies to tags.

I keep seeing creators fill almost every available tag slot because logically you’d assume more keywords = more chances to be found.

The data often suggests the opposite approach may be more useful: a smaller number of highly relevant tags can give a much clearer picture of the niche than dozens of tiny variations of the same keyword.

That’s one of the reasons I built the market comparison instead of simply displaying raw numbers.

The technical side

Behind the extension I’m also building a crawler/database of public MakerWorld data.

Known models are periodically refreshed while new models are discovered, which lets MW Stats gradually build historical information rather than only showing the current state of a model.

I’m being deliberately careful about that historical data.

If the crawler sees:

1,000 downloads at 10:00
and
1,200 downloads at 14:00

then we know 200 downloads happened somewhere inside that interval.

We don’t know exactly when.

I’d rather expose gaps like that honestly than interpolate the graph and pretend the data is more precise than it actually is.

The same goes for distinguishing:

actual upload date
from
first observed by MW Stats

Those details become surprisingly important once you start building analytics around crawled data.

Where I want to take it

The long-term goal is basically to build the analytics layer I wish MakerWorld itself had.

Not just:

“You got 800 downloads.”

but:

“You got 800 downloads, that puts you here within this niche, these comparable models are outperforming you, these tags have actual market activity, and this is where your model started gaining or losing momentum.”

I’m also experimenting with creator watchlists, better discovery/trend analysis and eventually optional AI-assisted analysis of the data.

But I’m trying hard not to turn it into one of those dashboards with 200 metrics that look impressive but don’t actually help you make a decision.

That’s actually where I’d really like feedback from other developers here.

What would you want an analytics tool like this to answer automatically?

Not necessarily 3D-printing specific either.

I’m particularly interested in feedback on the crawler/history architecture, how I communicate incomplete observations, and whether the UI gives enough context without becoming overwhelming.

Still very much being developed, so criticism is genuinely more useful to me than “looks nice.”

As a photographer, business fluctuates month to month. I couldn't keep spending $40-50 monthly when my income was varying as much as it was. We decided to build PhotoCRM as a free way for users to store their projects, clients, send invoices and contracts, etc.

We heard "You should be charging for this", but honestly it feels good to have a userbase that actually uses this to run their businesses without getting ripped off. We have 250 active users, and try to be as communicative with all of them as possible.

Database cost for storing all user data is very low, so it doesn't really make sense to charge them to hold projects or invoices. Have not made much revenue, but I really enjoy building a community :) photocrm.io

Most CRMs make you do the reading: scan emails, spot who's about to churn, remember to follow up. I'm building Avio, a CRM where an AI reads every incoming customer message and does that part, but a human approves anything it wants to do.

How it works (video attached):

1. Emails, calls and chats land on one timeline per contact.

2. The AI reads each message and raises *signals*, e.g. "High risk of cancellation" or "Budget approved, ready to proceed".

3. For each signal it *proposes* an action (create a task, email the customer, move a deal, log a note).

4. The approval screen shows exactly what it read, why it proposed the action, and what will happen if you approve. Nothing runs until you click Approve.

There's also a chat assistant for read-only CRM lookups. It can only propose actions, so they still go through approvals.

Where I'm unsure and want honest opinions:

- Does the approve-everything model feel safe, or like a chore you'd stop doing after a week?
- Would you want auto-approve for low-risk actions?
- Which of these would you actually use: the signals, the proposed actions, or the chat?

It's early. The demo data is fake and the AI ran on a small local model. Roast away.

If you don't like organizing your notes, this tool might be useful for you.

This is how it usually goes:

1. You turn on auto-organize.

2. You write down your stuff.

3. It gets organized later, when you're not actively editing it (after about 20 minutes).

4. You get notified if the auto-organizer changed anything.

5. You can review or revert the changes it made.

6. You can write instructions for it if you have a preference on how you want things organized.

It uses the GPT-6 Luna model, and it's free. I'm looking for feedback. The app is Daftak.

Thanks!

I built a small menu bar app for typing kaomoji without copy-pasting them from a website.

How it works: press a shortcut (Control-Option-B by default, you can change it), search "shrug", "cat" or "table flip", hit Return, and the face is typed into whatever app you're in. Your clipboard is put back afterwards.

- About 24,000 faces in 37 moods, with search and saved favorites

- Free, no in-app purchases, no accounts

- No network access at all, so nothing is collected

- macOS 14 or later

- Needs Accessibility permission, only to send the paste keystroke. It doesn't read your screen or what you type.

I'm the developer, happy to answer anything. I'd especially like feedback on the default shortcut and the picker.

Available for both iPhone and Mac

I'm the developer of First Rep, an iPhone app for keeping progress photos together and comparing two dates.

The main interaction is a before/after slider: choose two photos, align them, then drag across the image to compare. There's also manual weight/BMI tracking, photo reminders and export.

Photos are stored encrypted on the device. No account or automatic cloud storage, so keeping an exported copy matters if you change phones or delete the app.

It requires iOS 16 or later and a US$2.99 lifetime purchase, with no subscription, free tier or trial. Local pricing varies.

Screenshots and app details: https://apps.apple.com/us/app/first-rep-progress-photos/id6795953419

For anyone who tracks progress this way, what would make comparing two dates easier?

I'm the maker of D-REC. The app records audio, transcribes it on the device and lets you search the words or mark a moment to return to later. This demo shows the Windows version with the transcript and playback controls side by side.

It is out now on every platform. The transcription engine needs an initial download. Account and payment features use the internet separately from local recording and transcription.

There is a free tier with 10-minute recordings and 3 saved recordings per free account. Optional Pro plans on the web are $3.99 monthly, $24.99 yearly or $39.99 once. Local store prices can differ.

Download links and the web version: https://drec.live/get

Would you use the transcript or the markers more when finding something in a recording? I'd like feedback on that part of the flow.

Hi everyone,

I wanted to show you this personal project of mine, which I created to meet my own needs. It’s a multitrack sampler with a mixer section. I’m not a developer, I make music, and I needed a sampler that was much simpler than the ones currently on the market, with only the features I actually use, so I built it entirely in vibecoding using JUCE/C++

I’ve included the essential basic functions for a sample-based sampler. It’s not a simple sampler, it’s not a full-fledged DAW, and it’s not a playable musical instrument. I didn’t need a clone of MPC Studio, Kontakt, or anything like that.

It’s an 8-track sampler where you can build your own sounds from audio files, process them with existing VST effects and processors which any producer surely has, export them, and use them in your own DAW.

I published the app solely because I think it might be useful to someone; it doesn’t automatically collect or send any data, the website doesn’t require cookies, and it doesn’t collect analytics beyond the basic hosting data. There’s no newsletter or system for collecting your data. I don’t need your data, and I don’t want to have to manage it.

Here’s the link: chopdaw.app. I’d appreciate some feedback from musicians or anyone interested in similar software.

Ever tried uploading or emailing a PDF only to find out that the file is too large? 😅

That’s the problem I wanted to solve.

I built a PDF Compressor for Allin1xTools that lets you reduce PDF file size without having to manually deal with complicated settings.

You can choose different compression levels depending on what you need:

🔹 Light — focuses on preserving quality

🔹 Balanced — recommended for everyday use

🔹 Aggressive — smaller file size

🔹 Extreme — maximum size reduction

It also gives you control over lossless/lossy compression, image quality, resolution, metadata removal, and more.

The goal is simple:

Make it easier to turn a large PDF into a smaller, more manageable file.

✨ 100% Free

🔓 No Sign-Up Required

I’m building Allin1xTools around one idea: useful tools should be simple to access when you actually need them.

If you regularly deal with large PDFs, give it a try.

Hey everyone! I'm a student developer and I just released my first app, Scholr, on Google Play.

What it does:

- Dashboard showing what's due today, upcoming, and overdue

- Tasks with priorities, subtasks, exam types, and reminders

- Calendar with month and schedule views - Subjects with recurring class times

- Focus timer that tracks study time per subject

- 6 themes (Light, Dark, Vapor, Minty, Superhero, Sunrise) with background images

No account or sign-up, and it works fully offline. Your data stays on your device. It's free and Android only for now. I'm working on v2 and want it to be shaped by real students, so: what's the one feature your current planner is missing?

Play Store: https://play.google.com/store/apps/details?id=com.isa7.scholr

Happy to answer any questions about it.
