u/App-Designer2

Yesterday was one of those days that reminds me why I still love building apps.

I launched TerraPulse, my real-time earthquake monitoring app, and in less than 24 hours a lot happened:

Apple approved the initial v1, followed shortly after by v1.2, which introduced a server-side notification system for faster earthquake alerts.

Then I submitted my first In-App Event.
I honestly expected it to sit in review for a while.
Apple approved it in around 30 minutes.

But the biggest surprise came afterward.
Shortly after going live, TerraPulse started appearing in the Weather category rankings across several countries. At first I thought it might just be the normal launch volatility of a new app, but more storefronts started picking it up and some positions began moving noticeably.

For example:
🇩🇴 Dominican Republic:** #38 → #28
🇪🇨 Ecuador: #44 → #23
🇦🇷 Argentina: #47
🇳🇮 Nicaragua: #33
🇵🇦 Panama: #42
🇭🇳 Honduras: #4**7
plus rankings in Colombia, Venezuela and other markets.

The app is still extremely new, so I’m not treating these numbers as proof of long-term traction. Rankings can move quickly, especially around a launch.

Now comes the more interesting part: seeing whether those positions disappear after the initial launch period or whether the app can actually hold and improve them over the next few days.

The app is 100% in Spanish🇪🇸

I’m working on the App Store presentation for TerraPulse, an earthquake monitoring app, and I’d like some fresh eyes on the screenshots.
Without overthinking it, take a quick look and tell me:

1. How many seconds did it take you to understand what the app does?

2. Do the first 3 screenshots communicate the main idea clearly?

3. Which screenshot caught your attention first?

4. If you found this on the App Store, would the screenshots make you want to learn more or download it?

I’m especially interested in your first impression, not whether every detail is perfect.
Any criticism is welcome, layout, text, hierarchy, colors, messaging, anything that feels confusing or unnecessary.

I’ve been playing around with Apple’s new MusicUnderstanding API and honestly… this thing is pretty damn cool.

It can analyze things like energy, pace, loudness, musical key, structure, instrumentation, etc. What caught my attention is that you can use those results over time, so the analysis can actually react to what’s happening in the song.

I’m currently experimenting with it in a small project called '…..‘ . Instead of just showing a traditional waveform or equalizer, I’m trying to turn the analysis into a visual “aura” that changes as the song plays.

So while the song is playing, the shape expands, contracts, pulses and changes depending on what’s happening musically. I’m also using the structure analysis to let the user jump between different parts of the song.
I’ve attached a few screenshots of where I’m at so far.

The cool part is that it’s not just an audio visualizer anymore. It feels more like the app is actually trying to interpret the vibe of the song.

Has anyone else here experimented with Music Understanding yet?

I’m curious what people are building with it, especially things that go beyond the usual “show the BPM / waveform” type of implementation.
Would love to see what you guys are coming up with. 👀🎶

I’ve been tracking my app’s keyword rankings across multiple App Store storefronts using a tool I built myself.
Over the last few weeks, I noticed something interesting with the keyword “Secure Key”.

Right now my app is ranking:
🥇 #1 in Germany
🥇 #1 in Brazil
🥇 #1 in Italy
🥇 #1 in India
🥈 #2 in Japan
🥈 #2 in Vietnam
🥉 #3 in Canada

(plus several other countries where it ranks in the Top 10)

What’s interesting is that my app is competing against much larger password managers in some of these storefronts.

I’m not claiming to understand Apple’s search algorithm, but I’m curious if anyone else has experienced a keyword suddenly becoming much stronger across multiple countries.

Has anyone seen something similar?

I’d love to hear your thoughts or experiences.

When I started publishing apps on the App Store, I always wanted a simple and affordable way to track where my apps were actually ranking around the world.

Most tools were either too expensive, subscription-based, or didn’t provide the level of accuracy I was looking for. Some scans were incredibly fast, but often missed rankings that were actually there.

That’s what inspired me to build RankingCheck.

It helps me track my app rankings across multiple countries, discover where my apps are gaining visibility, monitor competitors, and receive notifications when rankings change.

Recently, I added new ASO features that allow developers to:

✅ Discover keywords that are already performing well in the App Store

✅ See which apps are ranking for those keywords

✅ Track keyword positions in real time

✅ Monitor Top 15 changes and ranking movements

✅ Find keyword opportunities and use them to improve your own App Store optimization

One of my favorite features is being able to scan keywords and instantly see which apps dominate them across different countries. This makes it much easier to identify keywords worth targeting and improve your app’s visibility.

I built this tool primarily for indie developers like myself, and I’d love to hear your thoughts or feedback.

I’m updating the App Store screenshots for RankingCheck and I’d love some honest feedback.

I recently redesigned the visuals and also added a new feature that lets users perform real-time ASO keyword research, including keyword rankings and search volume insights.

Do these screenshots clearly communicate the value of the app?
If you saw this page in the App Store, would you understand what the app does within a few seconds?

Any feedback on the design, wording, colors, or feature presentation would be greatly appreciated. Thanks!

I did them on Figma.

I made them Minimalist, Big Title, small Subtitle, white backgrounds.

Any Feedback will be appreciate 🤝

It’s amazing to see how this keyword is performing. The algorithm has identified “Secure Key” as a highly relevant keyword for my app. When I search for “Secure Key” in Germany, my app shows up as the #1 result, which is a great sign that the keyword association is working exactly as intended. 🚀

My two month old app result.

What do you think? 🤔

A little personal story.

I kept hearing my wife saying:

“Where’s my phone?” 😂

Not once. Not twice. Multiple times every day.

Then it became both of us. Looking under pillows, on the couch, in the kitchen, random places… sometimes while the phone was literally nearby the whole time 😅

Then I noticed something: it wasn’t just us.

Friends, family members, parents with kids running around the house… everyone seems to lose their phone constantly.

So I decided to build something simple.

I created HeyPhone. You choose your own keyword and when you say it, your phone responds with a alarm and notification , even in silent mode.

I recently localized it into Spanish, English, German and Italian.

Funny enough, I built it because of a small everyday problem at home 😄

Curious question:

How many times do you genuinely lose your phone during the week?

Necesito una primera impresión totalmente sincera 👀

Ya lancé mi app, pero aún estoy ajustando las capturas de pantalla de la App Store.

¿Qué es lo primero que se te viene a la mente al ver estas capturas?

No me refiero a lo que piensas después de leerlo todo. Me refiero a tu reacción inmediata en los primeros 2 o 3 segundos.

¿Entiendes al instante qué hace la app?

¿Alguna captura de pantalla te parece confusa, recargada o innecesaria?

Y una cosa más: ¿el personaje morado hace que la experiencia sea más memorable o distrae?

Tengo mucha curiosidad porque después de mirarlas durante días, ya no puedo juzgarlas objetivamente 😅

EDIT: More context 😊

I realized some people may have been trying to understand the screenshots without fully understanding the language, so here's a bit more context.

The app is called HeyPhone.

You create your own custom keyword and activate listening mode. If you can't find your phone later, you simply say your keyword out loud and your iPhone responds with a sound, even if it's on silent mode.

You can also set multiple keywords for different situations, use Apple Watch controls, trigger the flashlight in dark places, view weekly stats, and more.

Basically: less "Where is my phone?!" and more "Ah, there it is." 📱

Hey everyone 👋

I'm working on the App Store page for my app and I'd love some honest feedback.

The app is called HeyPhone. You choose a custom keyword and when you say it out loud, your iPhone responds with a sound so you can find it more easily.

I just finished the screenshots and before submitting everything, I wanted to ask:

If you randomly saw these in the App Store, would they make you stop scrolling?

Would you feel curious enough to tap and learn more, or even download it?

I'm especially interested in first impressions:

Do the screenshots clearly explain what the app does?

Does the character help or distract?

Which screenshot grabs your attention first?

Anything you would change?

Brutal honesty is welcome 😄
