A helper that does the subsidy paperwork for small home daycares

Many families pay for childcare with help from a state subsidy program. But for the small, home-based daycares that care for a lot of these kids, the paperwork is miserable. Providers have to track attendance, fill out state forms, submit billing through clunky government portals, and chase down payments when something gets rejected. Some providers just stop accepting subsidized families because it isn’t worth the hassle. That means fewer spots for the families who need them most. I wish there were a simple tool a home daycare owner could use on their phone. They’d check kids in and out each day, and it would take care of the rest: fill out the state’s billing forms, flag anything missing before it gets rejected, and explain in plain English what to fix when something goes wrong. It doesn’t need to cover every state at first. Starting with one state and doing it really well would already help a lot of people. A bigger version could also help someone get licensed to open a home daycare in the first place, since the licensing process scares a lot of people away. More licensed providers means more open childcare spots. What would make it great: Works on a phone, since providers are busy with kids all day Uses plain language, not government jargon Catches mistakes before submission, so payments aren’t delayed Free or very cheap for small providers

A syllable-pair explorer for kids learning Chinese pinyin that lists the words each pair makes

Young Chinese learners could use a toy where they pick two pinyin syllables and see every word those syllables can form, with tones, meanings and pictures. A switch would let the child search with or without tones, since in films the tones are often hard to hear. It could be built on a free, open Chinese dictionary as a simple website, helping kids look up words they hear in subtitled videos.

A phone app that reads the numbers off a basic bathroom scale and saves them for you

Some bathroom scales flash weight, BMI and body-fat readings on a small screen one at a time, so copying them into a spreadsheet by hand is slow and easy to get wrong. A simple phone app could watch the scale's screen through the camera for one full round, read each number, and save them in the same order every time. It could then copy them straight into a spreadsheet, and get better at reading different scale models over time. It would only copy the readings down, without interpreting them or giving medical advice.

A tracker for which registrar holds each of your domains and where its DNS points

People who buy domains from the cheapest registrar lose track of where each is registered, when it renews and which nameservers it uses. Add domains manually or by lookup and see renewal dates and nameserver changes in one list.

A simple dashboard of red and green lights for everything you run

A flat list of services, jobs and checks with just green or red status, not charts or analytics. Each check is a URL ping or a webhook; it's for small teams and solo operators. Self-hostable in a single file.

A hex editor with fuzzy field-aware search for binary file formats

Searching a binary for 'a header whose fields look like this' is hard with plain hex search. An editor would let you describe structures with partial values and find matches. Pairing with simple format definitions would make it practical.

Asked for in an Ask HN thread about wished-for dev tools

A way to run your CI job locally in the same environment before committing

Developers end up committing repeatedly just to debug pipeline YAML. A tool would reproduce the CI environment on your machine so you can iterate on scripts locally. The pain is mostly in matching images and secrets.

An ssh-in-and-get-a-disposable-container service that vanishes on exit

Type ssh to a host and land in a fresh throwaway container or microVM that is destroyed or paused when you disconnect. Useful for testing untrusted scripts or trying tools without polluting your machine. Keep it self-hostable and hardened.

A browser extension that makes you restate their point before posting an angry reply

When you hit reply on a heated comment, it pauses for a minute and asks you to sum up the other person's view in one sentence. If your version is far from theirs, it shows both side by side before unlocking Post. No scoring or AI rewriting, just a speed bump.

A scenic-drive navigation app with tappable saved places and a speedometer

Drivers who enjoy the journey want routes that prefer backroads and two-lane highways, saved places that stay visible, one-tap waypoint adds without ending navigation, and a speedometer even outside navigation. Built on open map data and routing.

A family planner that tracks each child's activities, gear, payments and chores

Parents of several kids lose track of practice times, equipment to pack, fees due and chores. Add each child, their activities and reminders, and see a family tablet view for the day. Calendars are too clunky for gear lists and bills.

A posing-prompt guide for beginner photographers shooting people

New photographers often freeze when asked to direct a couple or group. A phone-friendly library of poses with plain-language cues to say aloud, filterable by number of people and setting, would help. Users can save favorites for a shoot.

A word-origin tool that reconstructs how made-up English words would have looked historically

Type a word that doesn't exist and see plausible earlier forms across Old English, Middle English and Proto-Germanic, or French through Old French and Latin. Uses sound-change rules to generate forms, great for language nerds and fiction writers. Show the rules applied so it teaches too.

An old-time radio player with no ads, downloads and 'already heard' tracking

Old radio drama fans lost their favorite app to a worse redesign. A player built on public-domain archives would offer ad-free playback, offline downloads, background play, and a marker for episodes already heard. Source libraries like the Internet Archive keep content costs low.

A knitting pattern viewer that remembers your row, repeat and notes

Open a pattern PDF, place a marker at the current instruction, and keep a row counter and a repeat counter beside it. Closing the app saves the page, marker, counters and notes together, with no public upload. Aimed at knitters and crocheters who juggle a PDF, counter and paper notes.

A random-interval workout timer you can load with your own exercises

Enter exercises (jog, walk, sprint), a set of possible durations, rest time and number of rounds, and the timer picks each round at random. Keeps interval training unpredictable without planning every block. Audio or vibration cues tell you when to switch.

A crowd-sourced 'what used to be here' history for local buildings

Many shops and public places had earlier lives that people like to rediscover. Pick an address or a spot on a map and read short, reviewed histories of what used to stand there, with dates and sources. Moderation and sources keep it trustworthy.

A crowdsourced aisle map of where items live in big warehouse stores

Warehouse stores rarely post aisle signs for products, so shoppers wander. Let people search an item and see the aisle and bay for their store, with community edits and recent-confirmation dates. Starts with a single chain and a map of the floor.

A tool that turns council meeting minutes into a traceable history of one local issue

Following something like a promised sidewalk repair across months of meetings is tedious. Pick passages from the minutes, keep their dates and source links, group them by issue, and show updates, corrections and outcomes in a printable timeline for a library or community binder.

A monthly money planner for freelancers with uneven income that also sets taxes aside

Freelancers can't tell how much they truly need when pay arrives irregularly, and they juggle separate apps for budget, projects and taxes. One place would combine upcoming projects and expected payments with bills and a suggested set-aside amount. It must clearly say it is a planning aid, not tax advice.

A lock-screen countdown that shows teachers how long is left in the period

A student teacher wants to see at a glance how much of each class period remains, without a loud alarm. Enter a bell schedule once, then show a quiet always-visible countdown on the phone or a classroom web page. A full-screen web version works first; a native Live Activity can come later.

A one-tap 'we're running low' QR button for shared workplace supplies

Staff who take the last gloves or towels often forget to tell whoever shops. Scan a QR code taped to the shelf, tap the item, and it lands on the shopper's list, with no sign-up for staff. Useful for care homes, day-cares, small offices and clubs.

A paste-a-guide tool that turns messy how-to pages into mobile step cards

On a phone, how-to articles are buried in popups and videos have no chapters. Paste a URL and get a clean, tick-off list of steps shown one at a time, ideally as a floating step view while you work in another app. Works best for repairs, setup and cooking-style guides.

A way to leave letters, voice and video for descendants to open decades later

Many people never learned who their grandparents really were. A simple tool would let you record messages and set delivery to a future date or life event, with a plan for who receives them and how files stay readable in 50 years. Export-friendly formats and a trusted-contact handoff are the hard part.

A shared birthday page where guests add photos, videos and messages

Family and friends often want to celebrate someone from afar. A host creates a page with a link, guests drop in photos, short videos and notes without needing an account, and the host gets a keepsake page or download afterwards. Optional reveal date keeps it a surprise.

A renter's vault for timestamped move-in and move-out evidence

Deposit disputes turn on proof of what the place looked like. A guided room-by-room checklist captures dated photos and notes at move-in, repair requests, and move-out, then exports one tidy report for a dispute. It documents evidence only and gives no legal advice.

A 'where did I put it' log for the stuff you stash safely and then forget

Spare tiles, the passport, seasonal decorations and tools all get stored 'somewhere safe'. Take a photo, type where it went, and search it two years later; households could share one list so relatives can look things up too. Simple search matters more than fancy categories.

A text-message to-do list you manage by texting a number

Some people would rather keep their to-dos in the Messages app than in a separate app. Text a number 'buy milk' to add it, text 'list' to see items, text 'done 2' to clear one, and optionally get a morning summary. Needs an SMS provider so keep costs and privacy in mind.

A trip photo drop where everyone adds quietly and it all unlocks on one day

Group trip photos end up scattered across phones and trickle into the chat for weeks. Friends add photos to a shared trip during the trip, nobody sees the pile, and on a chosen date everything unlocks at once as a shared album. Think of it as a mini reveal party for the memories.

A pantry tracker that learns what you bought from a photo of the receipt

Food goes bad because nobody remembers what is in the fridge or when it expires. Snap the grocery receipt, get a rough inventory with suggested use-by dates, and see a short list of what to cook before it spoils. Manual correction matters more than perfect scanning.

A recipe saver that strips the life story and gives you just the recipe

Paste a recipe link and get a clean card with ingredients and steps, no ads or backstory. Scale servings, tweak amounts, add your own recipes, and keep a big-text cook mode for when your hands are messy. Offline use and a one-time price (or fully free) are part of the appeal.

A password helper for the relatives who can't manage their own logins

Older parents often can't cope with password managers that assume they understand vaults and autofill. A family member would set up and store the logins remotely, while the parent sees a few big buttons on their phone that open the right site already signed in. Success is measured by how few taps and decisions the parent faces.
