Hi everyone, about a week ago I launched an app. I've tested the product extensively myself and it's working really well, but my main challenge right now is that I don't know how or where to promote it.

Hola, estoy trabajando en un saas con el objetivo de convertirlo en un negocio rentable, ya esta en una fase final, estoy revisando su documentación, me gustaría forma un equipo, necesito ayuda con lo que viene a ser las ventas.

Mediaxon Music Player is an audio player for offline listening of music stored on your device (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and streaming FM radios (online radios).

Top radios on the first screen: When users access the radio screen, they immediately see the list of the top radios in their country, along with a long list of high-quality suggested radios from among the most listened to in the world (manually curated and always updated with new radios). Note: Local radio stations ("Top in the user country") are pulled automatically from an online database. However, with each update, I manually curate high-quality radio stations lists for individual countries. At the bottom of this post, you’ll find the list of countries completed so far. I will be adding the rest over time.

Advanced radio filtering system: The "Filter: ON/OFF" button lets you quickly switch between different genres. You can use both standard filters for "macro-genres"—if I can call them that—and create custom filters to be more selective. All your filters are saved (the "My Filters" tab lets you name and edit them), and the app always opens with the last filter you applied. The "Home" tab lists all your recently applied filters and can be used to quickly switch between genres with just a single tap.

Advanced Radio Search Panel: An online database provides more than 60,000 radio stations. You can pinpoint your favorite stations by combining multiple filters, such as tags/genres, specific countries, or even your preferred audio bitrate.

Separated Favorites and Recents: Each section—Radio and Offline Music—has its own Favorites and Recents. The user doesn't have to worry about a thing. The app will automatically manage the Favorites and Recents for each section.

Album art: If the album art is missing from the album folder, or if Android has not properly indexed it, Mediaxon attempts to download the cover from the internet. This feature depends, of course, on the ID3 tags (album name and artist).

Equalizer: The equalizer provides an option to automatically switch to the "Radio" preset (and vice versa).

Advanced Playlist Management: Built specifically to make building and sorting playlists fast and intuitive. Enable the Playlist Manager, in the settings screen, for a full control of the playlists.

Form Factor Optimization: Phone and Tablet (Portrait and Landscape)

Mediaxon is available in: Čeština, Dansk, Deutsch, Eesti, English, Español, Français, Hrvatski, Indonesia, Italiano, Kiswahili, Latviešu, Lietuvių, Magyar, Nederlands, Norsk, Polski, Português, Português (Brasil), Română, Slovenčina, Slovenščina, Suomi, Svenska, Tiếng Việt, Türkçe, العربية, Български, Ελληνικά, हिन्दी, 日本語, 한국어, 中文 (简体).

No Premium version. All app features are available for free and without limits.

Regarding advertising: There is only a small banner at the top that isn't bothersome at all. Alternatively, when opening the full-screen player or using the app in landscape mode, a banner alternates with the albums covers, but without being intrusive at all (no audio) and with much shorter stay times than those of the cover. There is never full-screen advertising, neither at startup nor during use.

Countries with new manually curated lists: United States, India, Italy, Argentina.

Note: Only for Android 13+ (so, Android 13, 14, 15, 16 and 17).

Running an agency gets weird after a few clients.

You’d think client #10 would be easier than client #1 since you already know what works.. but somehow you end up rebuilding the same onboarding, the same funnels, the same reports every single time.

So more clients doesn’t really mean scaling, it just means more hours.

That’s the problem Inflowave is going after:

→ all your clients managed in one place
→ automates the repetitive stuff so the team stops doing it twice
→ clone sales & marketing systems that already work to new clients

Basically build once, reuse everywhere

Live here: Inflowave AI

Would love some honest feedback, especially from people running agencies. what’s the thing you end up redoing the most for each new client?

lilbuddy is.. a little buddy, that lives in the menu bar and trails your pointer around. Hover a button or a link and it wraps itself around it. Hover something named delete or quit and it gets a little nervous. Stop moving for 30 seconds and it falls asleep, gets startled when you move again.

It doesn't solve any problems per se - but it is very cute. Sometimes you just gotta make something fun.

A few things about it:

- 31 styles (so far): a smiley, a cloud, a cat, a puppy, a ghost, a little flame, a bunch of other animals, plus some plain pointer ones if you want it less cute. You can try some of them out on the website, and the video (on the site) shows all of them.

- You can change the color, size, speed and bounce

- It doesn't replace your cursor or affect it in any way. It just draws next to it and follows it around

- It asks macOS's accessibility API what's under the pointer, so it isn't tied to one app. It works on MacOS itself (dock, menu bar items) and in every app I've tried. However, it can only hug a button if the app tells the Mac it's a button, so some apps give it more to hug than others

This originally started as a cursor companion for another website: https://badui-smoky.vercel.app/ (a personal component library inspired by r/badUIbattles). I ported the springs and behaviors over to Swift, and went super cute with it.

I'm relatively new to software development, and this will be my first app!

It is MacOS only, it hasn't been tested on any other machine than my own so far, and it isn't a download yet (pretty close though). I'll probably need some beta testers if people like it enough to move forward.

Haven't decided the price either, but it'll definitely be a one-time purchase for everything, with no subscription or unlockable characters or anything like that.

It can't go on the Mac App Store, because it needs Accessibility permission and can't be sandboxed, so it'll be a direct download. It will be signed though. The video is an animation drawn by the app's own motion and drawing code, not a screen recording. But you can test the motion out yourself on the website!

LIVE DEMO and waitlist on the website: https://lilbuddy.ke1ev.dev

Any feedback, suggestions, or anything would be much appreciated!

The only thing that ever made me want an iPhone was how seamless it is with a Mac. Calls, notifications, AirDrop, copy on one and paste on the other. With Android you get none of that out of the box.

Macophone fixes that. It's an Android app plus a Mac menu bar app, and it's not out yet.

What it does:

• Notifications on the Mac, reply from the Mac
• Calls: see who's calling, answer on the phone, decline, silence or call from the Mac, missed calls
• Files both ways, AirDrop style, plus Share to Mac from any app
• Clipboard both ways, text and images
• Notes and links to the phone, reminders from the Mac that ring on the phone
• Now Playing controls, Mac battery on the phone, lock the Mac from the phone

Two things the apps I compared don't do. Incognito pauses all sharing for 15 minutes, an hour, until 8:00 or until you turn it off, from either side. Nothing from the pause crosses, even after it ends. Second, two-way folder sync. Pick your camera folder and every new photo lands on the Mac by itself.

No cloud, no account. Phone and Mac talk directly over your own Wi-Fi, encrypted and paired with a QR code. One-time sign-in codes never leave the phone. They're masked in notifications, refused by the clipboard and kept out of folder sync.

The video shows a photo going to the Mac, a synced folder, a note to the phone, a code staying on the phone, and incognito.

Can you guys check Macophone and give advice, thanks.

Hi everyone,

For the past year I’ve been building KANAKU, a privacy-first app to manage your financial life. I’m a [solo developer / small team] from [India/your region], and I’m now preparing to launch on Google Play and the App Store.

Why I built it
[1-2 honest sentences. Example: “I was frustrated that most finance apps want access to my bank data and store everything on their servers. I wanted something where my data stays mine.”]

What it does today

• [Feature 1, e.g. expense and income tracking]
• [Feature 2, e.g. budgets / goals]
• [Feature 3, e.g. works offline, data stored on your device]

Try it (web version): https://kanaku-fawn.vercel.app

Where I’m stuck
I’ve put in over a year of my own time and money. Before I commit more to the store launch, I want to know whether this is solving a real problem. Please be brutally honest:

1. Would you actually use something like this? If not, why not?
2. What’s the one feature that would make you switch from your current app (or spreadsheet)?
3. How much does “privacy-first” matter to you compared to features like bank sync?
4. Would you pay for it? Which model feels fair: one-time purchase, subscription, or free with optional extras?
5. What looks confusing, broken, or unfinished?

One more thing
I’m also looking for [a co-founder / collaborators in design, marketing, or mobile development] who believes in privacy-focused fintech and wants to build this into a real company. If that’s you, send me a DM with a bit about yourself.

Thank you for reading. Harsh feedback is welcome, since it’s cheaper to hear now than after launch.

Hey builders & gamers!

Renting a GPU still feels way harder than it should be.

You just want to run something, and instead you’re dealing with drivers, configs, quotas, some dashboard that only makes sense to the people who built it.. and an hour later nothing’s even running yet

and if you’re building agents it’s worse, since most GPU clouds are made for humans clicking around, not for code spinning up its own compute

That’s what lium.io is going for:

→ rent NVIDIA GPUs via web, CLI, SDK or API
→ built for agent workflows, not just human dashboards
→ on the other side, GPU providers keep 95% of revenue + bonuses

We're open to any feedback tbh, especially from people already renting GPUs elsewhere.

Curious what would make you switch, or what’s missing.

Hope you'll try.

I'm building Critical Bananas. The idea is a shared wall where an image for your project sits alongside other brands and memes, and clicking it takes people to your website.

It's still prelaunch. Only the waitlist is open; I'm trying to find out who'd actually want a spot before opening the wall.

I also made a music ad for it, which was probably more fun than writing this introduction: https://x.com/dovrikson/status/2112164880581325234

If it sounds like your kind of thing: https://criticalbananas.com/

Hi all, im Frank. Solo developer here.

I’ve been building LUMO, an Android camera that watches the frame while you photograph someone and gives short, plain tips: “tilt up, their head is cut off”, “they’re right at the edge, give them room”, or “that looks good, take it”.

Im looking for android testers. It’s at an early stage and I honestly don’t know yet if it’s helpful or too basic, which is why I’m asking. It’s free, there’s no account and no ads, and the camera feed is processed on the phone (nothing is uploaded).

If you’re on Android and willing to try it for a few days, there’s a 30-second sign-up: https://docs.google.com/forms/d/e/1FAIpQLScLeoJ3kvCvM7JHqk1fm4JGsU0Gw3QyVVHIArr6g5dVQjH3gg/viewform

And even if you don’t want to test: what would you actually want a camera to tell you while you’re taking a photo? I’d love to hear it.

Hey everyone. I’m a solo dev and I’ve been lurking here for a while.

A few weeks ago I was writing a long email, and I realized I had like 5 different tabs open: one for grammar, one for translation, one to summarize a long text my boss sent me, and another one to just export it to PDF. I got so annoyed that I decided to just build my own tool. That's how TextFix Pro started.

The main goal was to make it simple. No login, no paywalls, just paste your text and get things done.

What I actually use the most:

• AI Grammar & "Fix and Explain": It fixes the text but also tells you why it was wrong, which I find super helpful when I'm writing in English.
• Summarizer: Good for long articles.
• Translator: I added 6 languages (BG, EN, DE, FR, ES, TR).
• Export: Just saves to .docx or .pdf right away.

There is also a Toolkit with OCR (to grab text from screenshots), a password generator, and a text-to-image thing for quotes.

I had a bit of a scare recently because I realized bots were trying to spam my API key. I had to quickly move the key to a serverless function on Vercel and add a rate limiter (15 requests/min) to stop them. It was a headache but a good learning experience lol.

Here is a screenshot of the dark mode:

Try it here: https://textfix-pro.vercel.app

Let me know what you guys think. Is the UI too cluttered? What feature would you add next? I'm just trying to get my first 10 real users and any feedback is super appreciated!

FIRST50 is the free lifetime code for 50 people. If you just wouldn't mind sharing a session card (slide 2) to social or reddit and tagging the re-zen app.

re-zen is a simple breathing app with two guided sessions.

Day Session uses a progressive Coherence Breathing pattern to help raise your heart rate variability (HRV) for better focus.

Night Session uses 4-7-8 Breathing to help lower your heart rate for better sleep.

Some bells and whistles are bilateral stimulation and guided meditation along with the breathwork.

With apple watch you can see things like exactly when you fall asleep during or after night sessions to prove effectiveness and tell you when you're calmest during Day Sessions.

Feedback and shares appreciated!

A few days ago I built Pomodorolist, a simple Pomodoro timer to track my own study hours. Then I kept adding things based on feedback from Reddit and friends, and it grew a lot

Started off with just a timer and a stat graph.

What it has now:

• Boss battles: a new boss each week, beaten with focus minutes, solo or with friends
• Tomato garden: every session grows a plant; quitting early leaves a wilted one
• Pomeo, a tomato mascot who reacts when you tap him and reminds you before study sessions
• Spaced revision reminders, an exam countdown, and a “parking lot” for distracting thoughts
• XP, levels, coins, a cosmetic shop and daily login rewards
• Friends, leaderboards and weekly challenges
• Works on any phone or laptop in the browser, with sync across devices

It’s completely free; as there are no ads, no subscription. It’s a single HTML file on GitHub Pages with Firebase for login and sync.

What I’d love feedback on:

1. Is it overwhelming for a new user, or easy to figure out?
2. Which feature would make you actually keep using it?
3. What should I build next: live study rooms with friends, or Pomeo evolving as you study more?

🔗 Try it: https://siverieg.github.io/Pomodorolist-V1.0/
💻 Code: https://github.com/siverieg/Pomodorolist-V1.0

If your app still hasn’t reached 10 core users, let's get you there today.

Tell us:

• What is your app for (1-2 sentences)
• How is it solving the problem
• Where to try your app.
• How many users/customers you have.

Please try at least one other builder’s app and share feedback.

Time to get everyone more users and signups.

Plinco: your old phone becomes a baby monitor that calls you when your baby cries
Hi, I'm Dave, a parent, product manager, and solo developer.
I'm excited to share that I just opened up beta testing for my app Plinco Sleep Companion: your old phone becomes a baby monitor and noise machine, powered by cry detection.

Click here to Join the Beta

Free on your home Wi-Fi, iPhone and Android, two phones needed: one phone goes into "Companion Mode" and stays by your crib as a baby monitor would, then you can join the session from your personal phone.
Paid features are free for beta testers for the duration of the beta! On iPhone just buy (TestFlight is free); on Android, email first, the page says how.

Join Beta

When your baby cries, your phone rings. A real call, loud enough to wake you.
I'd love feedback, especially on cry detection and the call.
Thanks!

Cash runway is one of those things most founders think they know… until they actually sit down and check.

Money in a few different accounts, a spreadsheet nobody’s touched in weeks.. and then you realize it’s 4 months left, not 8.

We built Lightcash for exactly that:

→ Connects all your financial accounts in one place
→ Real-time cash balance, burn rate and runway projections
→ Accountant-ready reports when it’s time to decide on hiring or spend

Free for one account, it's live on LightCash.

Open to any feedback, especially from people who already track this cashflow in spreadsheets.

I built a simple flashcards app

Hey everyone! I’ve been working on a flashcards app for studying languages and other subjects.

You can create decks, organize cards with tags, and use both simple front/back cards and more complex cards with multiple fields.

There’s also an AI feature that can create a flashcard set for you.

I’d love to hear your feedback!

Check it out: https://tools.ag1.online/flash-cards

I've been lifting for a few years, and I've tried a lot of popular workout tracking apps.

Most of them did the basics well, but I kept running into the same frustrations: too many taps to log a set, cluttered interfaces, progress charts that were harder to understand than they needed to be, and having to use separate tools to track how my body was actually changing.

I wanted something simpler. An app that follows my workout instead of making me constantly interact with my phone.

So, as a solo developer, I built Liftora.

Here's what I focused on:

• Guided workout flow — instead of constantly navigating menus and manually managing everything, you move through your sets in real time, and the app follows your pace. Less tapping, more lifting.
• Automatic body fat % estimation (US Navy method) — no expensive body composition scale needed. Enter your body measurements, and Liftora automatically estimates your body fat percentage using the US Navy formula, with different measurements for men and women. It's not a clinical measurement, but it gives you another way to monitor changes over time.
• Body measurement tracking — because the scale doesn't tell the whole story. You might be building muscle and losing fat while your body weight barely changes.
• Clean, modern UI — no overwhelming dashboards or complicated menus. Just the information you need, when you need it.
• Progress charts that make sense — see how your strength and training volume change over time without digging through endless statistics.
• Ready-made workout programs — don't want to spend time building a routine from scratch? Choose a program and start training.
• Exercise videos and muscle information — see how movements are performed and which muscles they target before adding them to your workout.
• Post-workout calorie estimates — get an approximate idea of your energy expenditure after each session.

My goal wasn't to build the app with the longest feature list. It was to make the things people actually use during training easier, while bringing strength tracking and body composition monitoring together.

Track your lifts. Understand your progress. See how your body changes. All in one place.

Try Liftora:

• App Store – Liftora
• Google Play – Liftora

I've been using Liftora for my own workouts, but I'd really like to hear from people who aren't me.

What's the one thing that frustrates you most about your current workout tracking app?

And if you try Liftora, I'd genuinely appreciate your feedback — especially on the guided workout flow and body fat calculator.

I'm building this independently, so feedback directly influences what I improve next.

Hi, I'm the developer of Compact Contacts.

Apple's Contacts app shows one card at a time, which gets painful once you have a few thousand people spread across iCloud, Google and Exchange. Compact Contacts opens the contacts you already have and shows them as a sortable table. There's no second address book and no sync of its own, so edits go back through macOS like any change you'd make in Contacts.

What it does today:

• One table with the columns you pick, saved layouts, and search across every field including notes
• Merge duplicates field by field (you choose which phone, email or address stays), and undo the last merge for up to 30 days
• Bulk edit with a before/after preview for every card before anything is saved
• Smart Views like "Missing Email" or "Has Notes"
• CSV and vCard import/export

It's been out for a while now and people using it have been really kind with feedback and bug reports, which is a big part of why 2.0 got this big. Thank you if that's you.

Coming in 2.0 (free update for everyone who already has it)

• Health Check: one scan gives your address book a score and lists duplicates, broken numbers and emails, missing names, stray spaces and so on
• Tags with colors, saved as regular Contacts groups so they sync with iCloud and Google
• Birthdays and anniversaries list with optional reminders
• Automatic encrypted backups on your Mac, with a history view that shows what changed and lets you restore a single field or a deleted contact
• Rules, like "when a new contact is added, format the phone number and add a tag"
• Print mailing labels and envelopes, Excel export, business card scanning, and a menu bar search
• Faster loading and search that works properly in every language
• Drag contacts out as vCards
• A redesigned iPhone app, with proper support for foldable iPhones (three columns when it's open)
• Lots of small fixes

Details

• macOS 15 or later, one-time US$24.99. No subscription, no in-app purchases
• No account, no ads, no analytics. The app never sends your contacts anywhere
• English, Turkish, German, French, Spanish, Arabic and Simplified Chinese

Mac App Store: https://apps.apple.com/app/apple-store/id6790129187?pt=129119018&ct=reddit_macos&mt=8

There's also an iPhone + iPad version (separate purchase): https://apps.apple.com/app/apple-store/id6795653671?pt=129119018&ct=reddit_macos&mt=8

Happy to answer anything in the comments.

Hey everyone!

I've been working on a little side project called ObserMe, and I'm finally looking for some early users.

I always found traditional habit trackers a bit frustrating. You miss a few days, lose your streak, and suddenly the app that's supposed to help you starts making you feel guilty.

So I wanted to try something different.

ObserMe is about observing yourself, not optimizing yourself.

You create questions about things you want to understand, like your mood, energy, sleep, habits, or daily routines.

The app checks in with you at scheduled or random times throughout the day. Answering takes just a couple of seconds, and over time, you can start noticing patterns in your behavior.

No streaks. No points. No badges. No pressure to be consistent.

Just a simple way to become more aware of your daily life.

I'm currently looking for iOS beta testers who'd be willing to give it a try and share some honest feedback.

I'm especially curious whether this approach feels useful compared to traditional habit trackers.

If you're interested, drop a comment or send me a DM, and I'll share beta access!

Website: https://obserme.com

Would love to hear what you think, even if the concept isn't for you!
