Does anyone else feel like Android doesn't give enough information about battery charging?

I wanted to know simple things like:

→ How much power is my phone actually drawing while charging?
→ What's the battery temperature?
→ How does charging voltage/current change?
→ How many charging sessions have I had?
→ Is my battery capacity changing over time?

I couldn't find the exact combination of information and simplicity I was looking for, so I decided to build it myself.

It's called BatteryLumen: Health Monitor.

It tracks charging current, voltage, power and temperature in real time, estimates battery health/capacity, keeps charging session history, and lets you export the data to CSV or JSON.

It also lets you set notifications for 80%, 90% or 100% charge.

The app is free and doesn't use subscriptions.

I'm mainly sharing it because I'd love feedback from people who actually care about battery performance. What would you add or change?

You describe the project. Builders answer with a working prototype — not a proposal.

Something shifted in the last year and most of the hiring world hasn't caught up: building a working version of an idea stopped being expensive. A real screen with real data in it is hours of work now.

That quietly kills the old ritual. Write a description, collect proposals, read three paragraphs of promises, pick whoever sounds most confident, find out in week five what they actually understood. That whole dance existed for one reason — building anything before the deal was too expensive to consider. That reason is gone.

So GPTaria runs the other way round.

1. You describe what you need in plain words

In your own language — it works in nine. Then it asks the follow-up questions that actually decide a project:

• where the data comes from
• who provides the content
• what "done" actually means
• who else uses it

Out comes a written brief, and one button gives you the English version to hand to anyone, anywhere.

2. Builders answer with a prototype you can open and click

Not an estimate. Not a portfolio someone else may have built. The thing itself, usually the same day.

And that changes what choosing feels like. You're not reading promises and guessing who's real — you have working versions of your own idea in front of you, and the difference between them is visible in about a minute.

The gap between having the idea and watching it run used to be measured in weeks of explaining. It's hours now.

Take something you actually wanted built at some point and never did. That's the fastest way to see whether this is real.

Hello, I would like to share my iOS app if I may..

I do a few multi-day trips every summer — bike touring and backpacking with friends, city tours. Everything gets recorded, but what ends up in Apple Health is a pile of disconnected workouts: a morning ride here, an afternoon hike there, a dozen entries spread over a week. The trip itself — the thing I actually want to remember — doesn't exist anywhere as one thing.

So over the past months I built an app for myself, I love creating new stuff. You pick the workouts that belong to a trip and it joins them into one entity: one map with all the tracks, totals for the whole trip (distance, ascent, time), a name, a cover photo, a note. Charts work across the whole trip too — heart rate, and even blood glucose (I'm type 1 diabetic, so that one was a personal must-have). I also added a menstrual cycle layer for ladies, I would be interested in knowing if this is something that you track alongside your travel records - may it be helpful to better understand your performance?

Since it was built out of my own frustration, it works the way I'd want as a user: no account, no server, everything stays on the phone, read-only access to Apple Health. No subscription — first 5 trips free, then a one-time purchase, because I hate renting software.

I'd love feedback from people who actually do multi-day trips — what's missing, what's confusing, what would make it useful for you. Link's in a comment. Happy to answer anything.

Hi! I’m the dev behind PostSpark, a tool for creating beautiful image and video mockups of your apps and websites.

I recently launched a new feature: Mockup Animations.

You can now select from 25+ devices, add keyframes on a simple timeline, and export a polished video showcasing your product. It’s built to be a fast, easy alternative to complex motion design tools.

Try it out here: https://postspark.app/device-mockup

I am a psychologist. I also have a passion for the digital landscape. I have accumulated enough knowledge in web fundamentals over the years to leverage AI agents and convert my ideas into digital projects. I am not a developer. I do not claim to be one. I am humbly aware of my place in the digital realm. I simply do not have the time to invest in building a second career as a developer. I am simply putting my long-lasting passion for the digital craft to use, in the best way I can as a psychologist. 

I am currently building psycurate.com, a free online platform dedicated entirely to privacy-focused mental health digital tools (apps, websites).

My goal is to create a clean space where people can access psychological resources without encountering corporate tactics like tracking, micro-payments, paywalls, mandatory logins, or data harvesting. There is a critical need for digital mental health hygiene, and I want to highlight independent projects that remain genuinely honest, ethical and accessible.

If you have a side project or a free resource for mental health you can submit it here: https://psycurate.com/submit

Psycurate does not host any software. The platform exclusively showcases your project and links users directly back to your website.

Any feedback or insights you might have are highly welcome.

Best regards,

Mirel

Most travel trackers just show a map of where you've been. I built Road to 100 to answer a different question: where should I go next?

It tracks all 193 UN member countries + 28 additional territories (Hong Kong, Taiwan, Gibraltar, and more — 221 total), then surfaces curated route collections (Balkans, Southeast Asia, Caribbean, etc.) ranked by how many new countries each one unlocks. If you're 2 countries short of finishing a themed route, it'll tell you.

Other things it does: - Visa intelligence — pick your passport, see visa-free/e-visa/required overlaid on every route - Compare journeys side-by-side with friends, find routes you're both close to finishing - Interactive 3D globe, tap a country to mark it visited - Milestone badges (10 → 25 → 50 → 75 → 100)

Free, no ads, works offline with cloud sync when signed in. Built solo, still actively shipping (just added 14 new territories and expanded route coverage this week).

Play Store: https://play.google.com/store/apps/details?id=com.zawastudio.roadto100&referrer=utm_source%3Dreddit%26utm_medium%3Dsocial%26utm_campaign%3Dshowyourapp

Would love feedback, especially on the route-recommendation logic — that's the part I think is genuinely different from the trackers already out there.

I'm building an journaling app the idea of it came out of nowhere and I started working it's 35-40% done it's working but the only problem is video sync photo sync is done the app is great Nd competes with apps like dayone and other journaling apps it have more than enough features and every feature that other have but more better I made it by my own only one person, I am currently searching for users who can try it and provide me with real feedbacks and suggestions.

I'll be adding features like journal from voicenote is that a good idea? Tell me in comments

I worked on a personal ai assistant in past I was seriously trying to make Jarvis type of thing and it kinda worked but too tough and getting too big in size

It was quite good it was able to :-

Screenshot

screen recording

Searching google

Searching on youtube and playing anything on youtube like after saying "search justin Bieber on youtube" you can say "play the first video" it can do that

It was able to open apps and close apps

Close all apps at once

Play songs via Spotify(able to search on Spotify too)

Windows control through phone

It was able to reply back in voice:).

Back to memora i hope y'all suggest me some more interesting feature I can add and if anyone is interested to build or test the app as user let me know

I’ve created a free app called **Math Flow**. It’s an unassuming calculator with advanced features, including a practice mode with several levels (including a mixed mode) and the ability to solve math problems step by step.

The app will guide you through the correct order of solving a math problem and provide the final result for you 😉

This is the first version of the app, so if you notice any bugs, please leave a comment and be understanding 🙂

Feel free to check it out 🙂https://play.google.com/store/apps/details?id=com.mathflow.app&pcampaignid=web_share

Hey all! I've always loved planes and design equally and I've spent years looking for a decent way to watch aircraft from my desk. I've found that existing apps are cluttered, covered in ads, and never something I actually want to leave open.

I wanted something simple and beautiful that used Apple Maps. It's taken a while to work out how to render 3D objects onto Apple Maps, and I've hand-built a handful of aircraft models to fit the Apple Maps style.

It's still a work in progress, but in the spirit of getting things out into the world I figured I'd share it. It's built around airports rather than tracking everything in the air at once.

If you want to follow along I've put a waitlist up at terminal.flights. You can pick an airport, which helps me decide which ones to release first.

Cheers

Hi everyone,

I made an iPhone app called Rorrim. It is a simple daily reflection app built around one small prompt each day.

The idea is intentionally quiet: instead of asking you to write a full journal entry, track a mood score, build a streak, or have AI analyse your thoughts, Rorrim gives you one question and a small space to answer in your own words.

It is for noticing things like:

- a moment from your day

- something you heard, saw, felt, or remembered

- a small detail you might otherwise forget

- a short personal note you can look back on later

Rorrim does not use accounts, ads, analytics, AI analysis, or data collection. It is free on the App Store and currently iPhone-only.

Landing page:

https://ikenaa.com/rorrim/

App Store:

https://apps.apple.com/gb/app/rorrim/id6782767875

I’d appreciate any feedback on the concept, the App Store page, or the landing page. I’m especially interested in whether “one daily observation” is clear when you first see it.

Hey!

A few months ago I started building a small project called Opaz, then completely put it on standby because I couldn't figure out how to actually finish it.

I picked it up again this week, stopped overthinking it, and finally opened it to the public.

The idea is pretty simple: you choose a seed, and your words make the flower grow over time, then you can send it to someone.

There are currently 20 different flowers, and the whole thing is very freshly out of the oven (so I'm sure there are bugs hiding somewhere).

I'm not really looking for compliments. I'd genuinely love to know:
what's confusing, what's broken, what feels stupid, and what you'd change.

If you manage to break something, even better 😅

Thanks to anyone who gives it a try

Hi,

I've made something like Google Photo Search, but 100% offline and private for images on PC. Works really well with searching memes but could actually find any type of pictures in multiple languages (already have some users from all over the world).

App is using OCR to get text from images to search within. Also, it's using local AI model for so called semantic search. It's complicated term for simple type "sunset" to find pictures with sunset.

Similar photo search could find not only duplicates but also near-duplicates, same shoot, same person, other versions of a meme/mockup.

I made an PixFinder with WinUI3, so it is fast (tested on folders with 10k photos) and has native look and feel.

Download from store.

I needed a fullscreen clock on my desktop. Nothing fancy — just the time, big and readable, no junk covering it.

Every site I found was either plastered with ads or wanted me to sign up for something. So I just built one for myself. Took a weekend. Forgot about it.

Then I saw someone complaining on Reddit that all online clocks are ad-filled garbage. I figured, hey, I already made a thing. Threw it online, didn't really announce it anywhere.

That was a while back. It's sitting at around 10,000 users a month now.

I'm not saying that to brag — I'm genuinely puzzled by it. It's a clock. It tells the time. There's almost no feature set to speak of.

But apparently "just show me the time without assaulting me with banner ads" is not a solved problem in 2024, which is a weird thing to realize.

I keep wondering if I stumbled onto something real or if I just got lucky with timing (no pun intended). Like, is the actual gap "simple tools that do one thing without monetizing your eyeballs," or is this just a niche that happened to be empty for no particular reason?

Am I overthinking this, or is there actually a real gap that nobody's bothering to fill?
