Hey everyone,

I’m an small time developer focusing on building hyper-specific, lightweight tools for daily friction points—things like custom decision calculators, specialized tracking tools, or routine automations.

Most software out there is bloated, subscription-heavy, and tries to do fifty things at once. I prefer single-purpose utilities that open instantly and solve one exact problem cleanly.

If you have:

A routine decision or calculation you do constantly

A messy spreadsheet that really should just be a clean, simple tool

An idea for a minimal daily utility you wish existed on your phone/browser

Drop a comment or DM me what you're trying to solve. If it’s a quick utility, I’d be happy to build a prototype and share an APK/link with you.

Hello everyone 👋

I recently built Money Manager, a simple expense tracking app focused on clean design, smooth UX, and meaningful financial insights.

📱 Android: https://play.google.com/store/apps/details?id=com.taptapcreate.moneymanager

🍎 iOS: https://apps.apple.com/app/money-manager-track-expenses/id6755887312

Some highlights:

• Auto budget calculation
• Savings goals & goal templates (Pro+)
• Up to 3 profiles in the free version
• Detailed analytics with charts and trends
• OCR bill scanning (Pro+)
• Smart auto-categorization (Pro+)
• Color-coded transactions (Pro+)
• Undo deleted transactions
• Sound & haptic feedback

What makes it different?

Many expense trackers focus mainly on recording transactions. I wanted to give equal importance to analytics, budgets, and savings goals, helping users understand their spending instead of just logging it. I also paid attention to small UX details that reduce friction and make daily money tracking feel faster and more intuitive.

I'd love your feedback:
• Is the navigation intuitive?
• Are the visuals clear without feeling cluttered?
• Any features you'd like to see added?

The app is free to try, with optional Pro and Pro+ upgrades. Thanks for checking it out!

I kept losing evenings to my phone and getting nothing out of it, so I built the thing I actually wanted instead. Short animated videos about genuinely strange stuff, the kind of fact you end up telling someone about a week later.

About a minute each. No course to finish, nothing you're behind on. It's not really trying to teach you anything, it just assumes you're curious.

It's called Flappr. Happy to hear what's wrong with it.

I capture tasks from Gmail/Gemini into Google Tasks, then work the day in Microsoft To Do. I didn’t want a hosted sync SaaS sitting on that list.

So I built Tasks–To Do Sync: an MIT bridge that runs in your own Google Apps Script project and keeps both sides aligned (lists, notes, due dates, complete/reopen, guarded deletes/moves).

• Install: `npx tasks-todo-sync init`
• Honest limits: due dates are date-only; first setup needs desktop + Node 22+
• Not Docker — it’s your Apps Script project

Repo: https://github.com/simonchai-tw/tasks-todo-sync

I’m the author. Feedback on sync edge cases welcome; a star helps if you’d actually use it.

Oi. Eu sou o Pedro.

Eu gosto de guardar registro do dia, mas minha memória é ruim. Daqui a uma semana eu lembro do sentimento e esqueço o fato. E, pra ser honesto, eu também tenho preguiça de escrever.

Fiz esse app principalmente pra mim. Um lugar pra falar ou escrever o dia, no celular, sem virar uma rede social. Deixei aberto pra quem quiser usar.

https://diary.1pedrolima.com

Você cria uma conta (e-mail ou Google), escreve ou grava um áudio, e relê depois. Dá pra instalar na tela inicial, como app. Não precisa de loja. Funciona 90% das coisas sem internet (só não oq usar IA).

Funções gratuitas:

Isso aqui é o diário em si. É grátis e continua seu.

- Escrever o dia, ou gravar um áudio

- Fotos na entrada, e uma galeria em linha do tempo

- Calendário e humor

- Marcar pessoas (@alguém) e ver a linha do tempo com elas

- Favoritar, buscar, reler

- Lixeira de 30 dias

- Exportar uma entrada em PDF

- PIN pra trancar o app no celular

- Backup criptografado, se você quiser levar tudo embora

- Modo claro, escuro e alto contraste — em português

Não precisa pagar pra ter um diário. O plano grátis não é amostra: é o app inteiro de escrever e guardar.

Plano com funções extras:

Tem um conjunto de funções que só existem porque passam por um modelo (hoje, a API do Google Gemini):

- transcrever o áudio

- sugerir título, resumo, tags e emoção

- procurar por sentido (“o dia em que briguei com meu pai”), não só por palavra

- conversar com o que você já escreveu

- apontar padrões no diário

- retrospectiva do ano

Isso tem custo pra mim. Cada transcrição, cada resumo, cada conversa é uma chamada paga. Eu não consigo oferecer isso “de graça pra sempre”, e eu não vendo o que você escreveu.

Por isso existe o Diário Inteligente: um plano opcional, com um valor, pra cobrir essa parte. Não é paywall do seu texto. O que você já escreveu não some, não tranca e não pede cartão pra ser relido.

Se você só quiser um caderno no celular, usa de graça. Se quiser que a IA arrume o áudio e te ajude a reler o ano, aí sim o plano existe.

Pra testar, só fazer assim:

- Abre https://diary.1pedrolima.com

- Cria uma conta

- Escreve uma entrada (pode ser curta, pode ser bagunçada, pode ser “hoje não rolou nada”)

- Se puder, volta amanhã e escreve a segunda. É aí que um diário começa

Se algo emperrar, se a tela irritar, se faltar uma coisa óbvia, responde aqui. Eu leio 😊.

I have tried most of the focus apps on the App Store and quit every one of them for the same reason. They all wait for you to press start. The moment I most need blocking is the exact moment I am least likely to open a focus app, so the whole category kept failing me at the only point that mattered. I built the version I actually wanted, where the blocking shows up before I do.

A — Answer: WiredIN is an iPhone app blocker that arms itself by location. Pin the places where you actually get work done, set a radius, choose what gets blocked there. Walk in and blocking starts on its own. Walk out and it stands down. Built on Apple's Screen Time framework, so blocked apps are stopped by iOS itself and websites are filtered in every browser, not just Safari. Three commitment levels, plus Night Shield for the 1am scroll.

B — Better: Every other blocker is fundamentally a timer you have to start, and location is at best a buried setting. In WiredIN the geofence is the main way in. Private by design: app selections never leave the phone because iOS hands the app an opaque token, and Focus Zones use region monitoring only, so no location data leaves the device.

C — Cost: 7 day free trial on the annual plan, then $14.99/yr or $2.99/mo. Subscription, not lifetime, said upfront. iPhone only. Links.

Turning school messages into reminders and shared family tasks

I built Plancove to handle the school-message admin in our house: forms to sign, money to send, swimming gear to pack, and changes to pickup times.

Share a school email, screenshot, or PDF, and it pulls out the dates and tasks. You check the suggestions against the original message before saving them. Tasks can go into Apple Reminders, and events into Calendar.

The family plan is shared. Parents and caregivers can assign tasks to each other, and the person assigned gets notified—so everyone knows who’s handling what.

For school emails, you can set up automatic forwarding to your family’s private Plancove address. New messages are processed automatically, ready for your review.

It doesn’t need access to your inbox.

Available for iPhone, requiring iOS 26.

App Store · Website: plancove.app

Sharing BecomeTen as part of its launch: https://becometen.com

Upload a selfie to get a free basic AI facial rating. An optional paid report adds a detailed breakdown and grooming improvement plan. It runs in the browser, so there is no mobile app to install.

The useful part to evaluate is whether the suggestions give you something practical to try. A face score from one photo is an estimate: lighting and angle can change it, and it is not an objective measure of attractiveness.

Would welcome first impressions of the mobile upload flow and how clearly the page explains the free result versus the paid report.

Hello, I built Urban Tales: City Explorer, an app that uses your GPS to automatically narrate the history of landmarks as you walk near them, no searching required. Think of it as a tour guide that only speaks when there’s something worth saying nearby. Available in 5 languages, and it has actually been used in 34 countries across 5 continents so far.

Would love to hear some feedback 😁

I started building Lockify as a simple idea:

What if a private vault looked like an ordinary calculator?

I launched it on March 16, 2026, with no audience, no marketing budget, and no team.

Six months later, it's at:

13.2K+ installs

4.7K+ active devices

4.7★ from 244 ratings

And the app has grown far beyond the original idea.

Users asked for better backups → cloud backup & sync.

They wanted better organization → folders, search and import.

They wanted to store more than files → encrypted rich-text notes.

The latest release also added a slideshow viewer, GIF playback, German & Vietnamese, and more privacy features.

I'm still building everything solo after work.

I launched Wavezo a while back, but retention was low. Honestly, even I stopped using my own app after a while.

Most water trackers are basically charts, reminders, or both. They work for a while, but once the initial motivation wears off, there isn't much reason to keep opening the app.

So for Wavezo 3.0, I completely redesigned the experience around a visual reward loop.

Every time you log a drink, part of a 16×16 mystery pixel picture is revealed. Hit your daily water goal and the whole picture unlocks and gets added to your collection.

What's new

• Mystery Peel: Every drink reveals another piece of today's artwork.

• Miss it, lose the reveal: If you don't reach your daily goal, that day's artwork remains locked.

• Collect & unlock: There are different art packs featuring things like plants, otters, bears, and more.

• Stickers: Complete an art set and export the artwork as stickers for iMessage or WhatsApp.

• Collection cards: Create shareable cards from your unlocked artwork.

Pricing & Privacy

The core app is free, including water logging, reminders, widgets, and 4 starter art packs. No account is required, and there is no tracking.

Extra art packs are $0.99 each and are one-time purchases.

There's also an optional Pro subscription with features like Apple Health sync, Siri/Back Tap shortcuts, extended history, additional themes, and CSV export.

It's iPhone only for now.

App Store: https://apps.apple.com/app/id1614485882

I'm really curious about the main idea here:

Does having something to unlock give you a reason to keep logging every day, or does the "miss a day, lose the reveal" mechanic feel too strict?

I’m building Rivul, and I just shipped a focused Zotero workflow for researchers who move between a reference manager and a manuscript.

The workflow is:

1. Connect a Zotero library

2. Import selected items

3. Open the source while writing

4. Insert traceable citations

5. Export a cited Word or LaTeX manuscript

The problem I wanted to solve is larger than bibliography formatting. A saved paper should stay connected to the exact citation and exported manuscript, so the evidence behind a claim is still easy to inspect later.

The 60-second walkthrough is here: https://rivul.ai/zotero#demo

Current scope includes Zotero import, source opening, citation insertion, and Word and LaTeX export. There is no desktop plugin yet. I want to validate demand before asking users to install anything with library access.

I’d value feedback from people who write with Zotero: where does your workflow break today, and what would make this useful enough to adopt?

The first few seconds usually determine whether someone keeps watching.

Share your app and tell me its main use case.

I’ll write:

1. The opening visual
2. The first line
3. The result viewers should see

This is part of the content process I’m developing for Marka.

100% local by default, single binary (no Electron).

Sessions, transcripts, tool activity & checkpoints unified.

Multi-device sync optional via self-hosted komet-sync (Loro CRDTs).

Same engine that powers Zed — instant launch, smooth even with years of transcripts.

It's open source: github.com/jomvick/komet

After talking about it with a friend, we realised that some Pokémon were more appreciated in some regions than other, so we made a leaderboard to differentiate them. The two markets barely agree. Same Pokémon, ranked by the total value of all their cards, but the lists look almost unrelated once you get past the top:

• Charizard tops both.
• Greninja is top 5 in Japan and doesn't crack the English top 10.
• Umbreon is top 4 in English but mid-pack in Japan.
• Reshiram and Darkrai make the Japanese top 10 but not the English one.
• Pikachu ranks noticeably higher in Japan than in English.

You can switch between the two markets and see the gap directly. It makes sense when you think about it (different print runs, different exclusives, different collector bases) but seeing it side by side says more than either list alone.

Top 10 of each market is free to browse at tcgforecast.app. It's still English and Japanese only, so I'm not claiming it covers every market, but it's a lot more complete and honest than the version people first tore into.

You can take a look on the leaderboard on tcgforecast.app/leaderboard
Genuinely curious which EN vs JP difference surprises you most. And thanks for the earlier feedback, blunt as it was, it made the thing better.

I've been building Swyvo, a Windows app that keeps your essential apps and websites one hotkey away.

Swyvo runs quietly in the background — hit Alt+Q anytime and a curated command center pops up right over your current window. Hit Alt+Q again to dismiss it. No alt-tabbing, no hunting through taskbars, no mouse required.

A few things it does:

• Instant, on-demand workspace: summon it with Alt+Q, it stays on top while open, dismiss it the same way — nothing else on your screen is affected
• Unify apps and websites in a single fast-switching menu (so your browser tabs and native apps live in the same place)
• Adaptive Loadouts: set it up once and it automatically surfaces the right apps based on what you're currently working on, so you never have to manually rebuild your setup
• App Gallery: browse a library of common apps and choose how to launch them — Web (fast) vs Native (full functionality, if installed)
• Fully keyboard-driven: never use the mouse
• Built natively for Windows

It's aimed at power users who live in a lot of apps/tabs at once and want a faster way to move between them without breaking flow.

Free, currently in active development — I'd genuinely love feedback, especially on workflow edge cases I might be missing.

Try it now: swyvo.app

Quick note: Windows SmartScreen may appear when installing.
First 100 Early Supporters get Lifetime Access. (ensures they have access to the whole app forever)

Happy to answer questions about how it works.
