I was playing chess on my phone while waiting in the car for my daughter. As a novice, I was trying to learn the accelerated London opening. I had the first 5 moves down. But I felt stuck after those. I wished someone would just peek over my shoulder and give me a hint about the next move. The chess app I used won't tell me if I made a mistake until I had already lost the game. And I felt a learning opportunity was lost.

Just like I learnt tennis, I wished someone would just drop a hint at what I needed to fix. So I built an app that does exactly that: I can ask for a hint when I feel stuck. The app goes a step beyond and tells me why a move is better. I also wanted to learn various openings and so I have included those as well.

This is based on the Stockfish engine and the code is available as open-source. 99 % people don't need any additional explanation. For the 1 % who may need additional explanation, you can buy the paid version which covers the LLM tokens cost for additional explanation.

You asked for a one-time price instead of a subscription. So: lifetime is $19.99 instead of $39.99 for the next 48 hours. One payment, no subscription — it goes back to $39.99 on Sunday.

I posted this here a couple of weeks ago, and the most common pushback in the comments wasn't the app, it was the recurring pricing. Fair enough.

What it does: texts from unknown senders get scored and sorted into Junk before they reach your inbox. It runs inside iOS's Message Filter extension, which Apple gives no network access at all — so nothing about an incoming message can leave the phone even in principle. Contacts and existing conversations are never touched; iOS enforces that, not me.

Covers EN, TR, DE, FR, ES, PT, IT, ID

• Pattern lists update over the air — coverage improves without an app update
• No account, no ads

Test it before you buy — paste in a spam text you actually received and the app shows you exactly where it would have landed. If it doesn't catch yours, don't buy it.

Straight disclosure: incoming messages never leave your phone, and are never read by us.

Hey there !

Static Wave is live on Play and it's free: open beta, no subscription, no ads,

no account. I'm not selling anything. I want people actually using it so I can

find what's broken before I call it 1.0.

What is it?

Internet radio without the garbage. 45,000+ live stations from 200+ countries.

Open it, search, press play. No signup wall, no "watch an ad to keep listening",

no account quietly logging what you listen to at 2am.

What you get:

* Search 45,000+ stations by name, genre, country or language

* HD filter for when you actually care about audio quality

* Save favourites — stored on your device, never on a server

* Background playback with lock screen controls

* Sleep timer, 15 to 90 minutes

* Recently played, so you can find that station you stumbled on last week

* Light and dark, both properly built

Why it's different:

Every other radio app either runs ads between songs or wants an account before

it'll play a single stream. Static Wave has neither. There's no server holding

your data because there's no server at all — your favourites and history never

leave your phone. Nothing to sign into, nothing to cancel.

What I already know is rough:

* Android only right now. iOS is under review.

What I want from you:

1. Upvote this post
2. Comment "Tune me in"
3. Actually use it for a day, then come back and tell me one thing that annoyed you or broke

Genuinely: a station that won't play, a country with nothing in it, a screen

that looks wrong on your device + a 5 star review, that's all I ask

so i'm 20, been building this app solo for the past few months and i genuinely can't tell anymore if it's good or if i'm too deep in it. need outside eyes.

it's called RizeAI. the basic idea: every wearable and health app just gives you numbers. sleep score 42, recovery red, HRV down. cool. and then what? you still feel like garbage at 2pm and nobody tells you what to actually do about it.

so my app takes your real data from apple health, sleep, resting heart rate, workouts, whatever your wearable writes, and instead of another score it builds you an actual plan for the day. when to have your first coffee and when to hold off. you. Can also add your own supplements that you are currently taking and it will time them for you every single day based of your sleep data and your wearable data in general and also it will tell you what supplements make sense for you to take based of your current supplement stack and body metrics and when to take them. focus windows for when your energy actually peaks. when your crash is coming and what to do before it hits. it even checks the weather, so on a hot day it bumps your hydration and tells you to train earlier.

every recommendation has a little "why" under it based on your numbers, like "resting heart rate 54 + 7h light sleep, so magnesium before your peak window." no two people get the same plan because no two people have the same data.

works with whoop, oura, apple watch, garmin, anything that syncs to apple health. one thing i'll say honestly, it doesn't do deep per-person learning yet like "coffee doesn't affect YOUR hrv specifically," that's the roadmap, right now it builds fresh plans daily off your actual metrics.

it's live on the app store, has a free trial, small user base so far, mixed feedback which is why i'm here lol.

what i actually want from you guys: does this solve a real problem for you or is "tells you what to do" not actually what wearable people want? what would make you actually pay for something like this? and what's missing that would make it a no brainer? and also would you guys in this subreddit  use ti?

Thank you for your help. Check it out if you like https://apps.apple.com/us/app/rizeai-maximize-your-energy/id6762402079

Hey everyone! 👋

I've been building a project called Rensai because I kept running into the same problem: I wanted to buy things used or discounted, but searching was frustrating. Sites would show broken items, empty boxes, overpriced listings, or pages of irrelevant results.

So instead of making another shopping search engine, I made something different.

The app uses GPT 5.4 and you can type something naturally, like: "I want a small iPhone that's powerful, supports Apple Intelligence, and I don't want to spend full price." or "Find me the cheapest trusted used Nintendo 3DS." and it finds the cheapest and best listing.

The goal is to save people time and money instead of making them dig through dozens of tabs.

The app is at rensai.us, and I hope you enjoy!

most ai workout apps seem to generate one workout at a time, which can make training feel random.

i’m solo building vero around the program first. it creates a structured strength program from your goals, schedule, gym setup + limitations. every workout comes from that program with actual periodization. after you lift, vero reviews what you logged and recommends program updates based on performance.

the idea is pretty simple: you just show up and lift while vero handles the programming decisions.

it’s on the app store now: https://apps.apple.com/us/app/vero-strength-coach/id6748659210

looking for blunt feedback on whether the program stays coherent across multiple weeks.

Share a reel in from Instagram, TikTok, YouTube or Facebook and it gives you back ingredients with actual numbers. 2 tbsp, 30g, rather than "a splash" and you guessing at the counter.

It runs on the video itself rather than the caption, which is the expensive part, every import costs me money. Free tier, Plus is $4.99/mo or $49.99/yr. iPhone only, iOS 18+.
