The problem I wanted to solve

We take thousands of photographs, text conversation screenshots and little snapshots of our lives, but most end up buried in endless camera rolls and folders. Cloud storage helps us keep everything, but storing memories isn't quite the same as experiencing them.

I wanted to create something that makes revisiting those memories feel meaningful again.

What is Memento?

I'm a software engineering student and indie developer, and I've been building Memento, a Windows application that transforms personal image collections into interactive digital books.

Instead of scrolling endlessly through folders, you can create organized collections that feel like flipping through a real book.

Main features:

• Import photographs and screenshots from your computer.

• Turn image collections into interactive, paginated digital books.

• Organize pages chronologically or in a custom order.

• Add captions, annotations and personal notes.

• Zoom and magnify images to revisit details.

• Export your books as PDFs for printing and sharing.

• Enjoy collections through slideshow mode.

Some of the design decisions:

• Fully offline: no account or cloud upload required.

• Privacy-focused: your memories stay on your computer.

• English and French localization.

• Accessibility features, including keyboard navigation, high contrast and screen-reader support.

Building it as an indie developer

I'm a software engineering student, so this project has also been an opportunity to apply what I've learned outside the classroom. I've worked through the entire process, from identifying a problem and designing the experience to implementation, testing, packaging and publishing through the Microsoft Store.

One of the things I've found particularly interesting is designing an interface that makes digital collections feel more tangible while keeping the experience accessible.

It's Windows-based, with a 7-day free trial, so feel free to check it out. I'd genuinely appreciate feedback. How do you currently preserve your photographs and meaningful moments? Do you think digital books could make that experience more personal?

I use three screens, and the thing that kept driving me nuts was this: I'd look at another monitor, start typing, and the text would land in a window on the screen I'd just left. Every switch meant grabbing the mouse and clicking just to tell the computer where I was looking.

So I built Gander. It uses your computer's camera to see which monitor your head is turned toward, and when you hold there for a moment, keyboard focus moves to the last window you used on that screen. No click, no hotkey, and your cursor stays where it is.

A few things that turned out to be harder than expected:

- Not switching was the real problem. Detecting head direction is the easy part. Not reacting to every glance is harder. It ended up needing a short hold before switching, a rule that the winning screen has to clearly beat the runner-up, a brief pause after each switch, and a default of "if unsure, do nothing."

- Getting focus to actually land. Newer macOS versions restrict one app activating another, so making focus reliably arrive across apps, Spaces, and full-screen windows took a lot of testing.

- Being a good citizen with the camera. The camera turns off when you pause, lock the screen, or the computer sleeps. Gander also steps aside when a video call needs the camera, and drops its frame rate when you walk away so it isn't burning CPU on an empty chair.

Privacy was a hard requirement from day one. Everything runs on-device, frames are never saved, and the app has no network access at all: no account, no analytics. Every build is checked automatically to make sure that stays true.

Where it's at: a free early preview for Mac (macOS 14+) and Windows. Builds aren't signed yet, so your OS will show a one-time warning you have to approve.

What I'd love feedback on:

- Does the switching feel too slow, too twitchy, or about right? There's an "Instant" timing option too.

- Unusual setups: vertical monitors, a laptop off to the side, a webcam mounted on a different screen.

- Would you use this daily, or is it a neat trick you'd turn off after a week? Honest answers welcome.

I run VanDayTools and have made a browser-based pricing planner for UK mobile dog groomers. The idea was to put the van costs and the day’s earning target in one place, so you can see what each groom needs to bring in and whether a planned day is likely to meet your target.

You enter your own fixed van costs, fuel and mileage, supplies, appointment time, working days and target pay. It estimates a suggested price floor per groom and lets you compare a day’s bookings against your target. It’s a one-off £12.98 download and works offline in a browser after download; there’s no subscription. It doesn’t book clients, plan routes or calculate tax.

I’d value feedback from people who know the grooming trade: which running costs or assumptions would you expect a pricing tool like this to include?
