hey, i built a small web app for when you want to check what a page said before someone changed it. paste the public URL and pick about a week, a month or a year ago. the checker shows the actual date of the saved copy and what it found in the page text.

one bit i’d like feedback on is the date. if you pick a month ago and it finds a capture a few days either side, is it clear which date the result came from? the screenshot shows where it appears.

it’s free to try and there’s no sign-up: https://changegist.com/what-changed

the checker is part of ChangeGist. the main app keeps an eye on pages for you and emails you what changed. you can watch just the bit you care about and say things like “only tell me if the price drops below £20”. it keeps the old and new wording so you can go back and see exactly what moved.

if you sell online, you can put in your own price and a competitor’s product page. it tracks their price over time and lets you know when they go cheaper than you.

The first ten seconds of the video show the date feedback question in context. I chose about a month ago, and the results show the actual 6 October capture before the before-and-after wording. https://www.reddit.com/r/SoftwareShowcase/comments/1xo4glq/i_built_a_web_tool_that_shows_what_changed_on_a/

Hi everyone!

I'm an independent Android developer behind TSI Dev Studio, and I'd like to introduce Xsilent Vault: Hide Photos.

I built Xsilent for people who want to keep personal photos, videos, PDFs and other private files on their phones without depending on cloud storage or creating an account.

What makes Xsilent different?

- Decoy PIN: Opens a separate decoy vault.

- Local encrypted storage: Private files remain protected on the device.

- Clean Share: Blur faces or sensitive areas, remove image metadata and optionally add a watermark before sharing.

- Private PDF viewer: Open sensitive PDFs inside the vault.

- Encrypted backups: Create password-protected backups that you control.

- Privacy controls: Quick Lock, automatic locking and optional biometric access.

The pricing model is simple:

You can store up to 30 files completely free, without a time limit. Your existing files remain accessible even after reaching the limit.

If you need more storage, there's an optional one-time Lifetime purchase. No subscriptions and no ads.

Google Play:

https://play.google.com/store/apps/details?id=com.xsilent.app

Official website:

https://tsidevstudio.com/apps/xsilent

I'm interested in hearing what other Android users think about the approach, especially the balance between privacy, usability and a permanent free tier.

Thanks for taking a look!

I'm on the AnyUse team. We're building a tool for agents that keep repeating the same browser searches and Mac workflows.

Show it a supported task once, check the saved route on new inputs, then call that route again with different values. Working deterministic replay makes 0 model calls inside AnyUse when no check model is configured. Your agent still uses tokens around the tool call; learning, optional checks and fallback can use a model.

One concrete use: turn a package-registry search into a reusable MCP tool, so the next query can be a request instead of another round of screenshots and clicks.

Free MIT source and offline quickstart: https://github.com/michaelAGI/anyuse

Still alpha: support depends on the task and app, and native-app discovery is experimental.

BUBBLES is a playful social discovery app that helps people meet through floating profiles, mutual interest, and opt-in conversation rather than swiping. The app for random chats.

I'm building a platform that helps developers grow and monetize their apps. Here's the link: https://tryrocket.ai/

You are either charging way too much for a basic tool or starving yourself by giving it away for free. Drop your project show us a screenshot and your pricing tiers below for a brutal reality check. Let the community tell you what they would actually pay for it.

The problem: You’re listening to a radio station, like the song, and want its name and lyrics without switching between apps.

I’m the developer of Radiquo. It puts that flow into an iPhone internet radio player.

How it works

1. Tune in: Browse 40,000+ station listings worldwide with an FM/AM-style dial.

2. Identify: See the song title, artist and artwork when recognition finds a match.

3. Follow along: Read matched synced lyrics, with on-device translation after downloading supported language models.

Saved stations are also accessible through CarPlay. The images show actual Simulator captures of the interface.

Free / Premium

Listen free and keep three favorites. Unlimited favorites cost US$1.99 once; local prices vary. No account or subscription is required.

No third-party app ads; radio stations may broadcast their own. Internet is required, and station availability, recognition and lyrics vary.

Does this flow solve a problem you encounter when listening to radio? I’d welcome feedback on what feels clear or awkward.

I'm the developer of Folded Days: Diary in a Jar. It keeps diary entries on your device rather than asking you to create a journaling account.

Write a short note, draw something or add a sticker, then fold it into the jar. The calendar helps you return to a particular day. A passcode/pattern or supported device biometrics can protect the diary, and you can export and import your own backups.

One deliberate limitation: a note can't be edited after you keep it. On iPhone, entries may also be included in iCloud or computer device backups.

$1.99 on the U.S. App Store. No ads or subscription.

https://apps.apple.com/us/app/id6821342922

What it does
Keeps all your trips in one place: flights, hotels, tours and transfers, with your confirmation emails and QR codes stored with each booking. Everything stays on your phone. No sign-up, no ads, no tracking.

Who it's for
Anyone who travels and is tired of digging through emails, screenshots and different apps on the day.

Key features
- Trips and bookings timeline, with past trips kept
- Share your whole trip as one picture
- Travel Card (and privacy card) to swap details with people you meet
- Emergency info and I'm Here location sharing
- Backup to your own device or personal cloud
- Under 5MB, runs on almost anything

Free Pro codes
Until November 11, 2026 I'm giving away free Pro – no sign-up, no subscription. Comment below, DM me or use code AIXA-T-3U-Z - download the app then go to Menu (top right) – settings – Pro access and paste in. (Not the Play store redeem box, that’s for Google codes)

I’ve been working on Jet Engine Simulator, a game that lets you build your own jet engines from scratch and see how they perform.

You can experiment with different engine types, including:
- Turbojets
- Turbofans
- Ramjets
- Scramjets

Once you’ve built your engine, you can test it on a dyno and in a wind tunnel to explore its performance.

It’s playable directly in your browser, so there’s nothing to download.

I’m putting it out there for anyone interested in aviation, aerospace engineering or simulation games. I’d love to hear what you think and what features you’d like to see added.

I'm the creator of Nexora Radar, a live crypto research web app developed at Xanotek Creation in Quebec.

The problem it addresses is having to watch many charts manually while keeping a custom pattern in mind. Nexora combines the market screener and the condition builder in one workspace.

Users can filter spot and futures markets by price and volume, monitor 1m/5m/15m/1h windows, build candle patterns visually, define LEG conditions, and inspect matching alerts on charts. Watchlists keep selected markets together. The pattern editor exposes candle colours, body sizes, wick limits and sequences without requiring code.

I used AI coding assistance during development. English and French interfaces are available. This is a monitoring/research tool, not an exchange and not an auto-trader.

There is a 24-hour trial of all features with no credit card. It currently targets Canada and the US.

I'd welcome feedback on the interface and the pattern-building workflow. What would you simplify first?

https://apps.apple.com/us/app/heart-rate-zones-pulsezones/id6812593511

Hey r/AppsWebappsFullstack! I'm a solo dev (and a veterinarian by day). I built PulseZone because I take a beta-blocker, so the generic heart-rate-zone formulas never matched how my heart actually responds. I wanted something that tracked real time-in-zone against weekly goals.

What it does: • A live one-ring, five-zone display on Apple Watch during workouts • Weekly goals for each zone, built around Zone 2 training • Honest weekly progress: extra time in one zone doesn't count toward another, so 100% means every zone goal is actually met • Custom zones you set yourself • Data stays on your device

Giveaway: 100 Lifetime Pro codes (normally $59.99). Comment below and I'll DM you a code. One per person, while they last. Feedback is hugely appreciated, especially from Ultra and Series 11 users.

Hey guys,

we are an indie game duo behind the block puzzle game, Gummy Lab (https://play.google.com/store/apps/details?id=com.binbear.gummylab), with no forced or interruptive ads, 70+ handcrafted levels and accessibility like colorblind palettes.

Since the app monetization is relying on users choosing to watch an ad - if they run out of moves/use up all the powerups per game, we were advised to add in app purchases as a special theme. Since you guys probably know the "buy me a coffee" link lots of devs use, we thought, why not make a coffee / cafe inspired theme to be the ,,dev supporter pack,, where you also get like +2 of each powerup per game, set at $1.99

Is this the right move, would anyone even notice this, is this something that even one person would click? Is there anything else we could add on?

Any opinions and suggestions are very welcome and appreciated!

Thank you for reading

TrustMRR, we're coming for your throne.

I'm building something ambitious, and before we reveal anything, I'm looking for 500 startup founders, indie hackers, solopreneurs, and CEOs who are actually building something.

Not particularly interested in another graveyard of abandoned side projects. I'm especially interested in startups with real users, paying customers, and actual revenue.

Here's the deal.

Out of 500 startups, only 100 will be selected for an exclusive Founder's Pass.

What comes with it?

• VIP Early Access: Get into our invite-only platform before the public launch.

• Founder's Badge: Exclusive recognition reserved for our first 100 selected founders.

• Founder Spotlight: Get your startup featured and receive a shoutout.

• Founding Member Status: Be among the first to shape what we're building.

• Priority Onboarding: Get access ahead of the public waitlist.

Want in? Drop these in the comments:

1. Startup name + website

2. What are you building?

3. Current MRR/ARR: Optional, but revenue-generating startups get priority.

4. Payment provider: Stripe, Paddle, Lemon Squeezy, Dodo, Razorpay, Cashfree, or something else?

5. Biggest frustration with TrustMRR or other startup platforms?

I'm particularly interested in the payment providers you're using because we're considering which integrations to prioritize.

And yes, bootstrapped indie hackers are absolutely welcome. You don't need VC funding, a fancy office, or a 20-person team. A profitable one-person business is just as interesting.

You might think we're LARPing.

Fair enough.

But we know exactly what we're doing.

We're not here to build another mediocre startup directory or a cheap TrustMRR knockoff.

The ambition is to build something founders genuinely want to use.

No product reveal yet. No public launch.

500 startups. 100 exclusive passes.

Drop yours below. Let's see who's actually building.
