I'm working on an iPhone app called PhotoGather. https://apps.apple.com/us/app/photogather/id6738232616
I've got 40k+ photos on my iphone, and wanted a better way to interact with them. The basic idea I had was to virtually stitch all the photos together into a gigapixel image, and navigate that image with pinch and zoom. On import, the app hierarchically groups photos based on date and similarity. The user can go back and edit the groups, change the layout, and adjust the size of photos if they choose.
The interesting I noticed is that in the process of curating and organizing my photos, I stumble across memories and moments that I had completely forgot.
Development Challenge: The app does two interesting things underneath the hood... First, given an arbitrary number of thumbnails with different aspect ratios, it finds the best sized rectangle that completely fits all the photos. This allows me to recursively stitch groups together and always output a rectangular thumbnail for the group. Second, the pinch/zoom UI uses these nested thumbnails directly without slicing/dicing to fixed sized tiles.

I’ve been working on Beacon, which just got Beacon approved on the App Store! It’s a mobile app to instantly answer “which friend is free to talk right now?” and summon them in a single tap.
Send your beacon to a group, and everyone gets a gentle ping. The first person who answers gets connected for a 1-1 call, and for everyone else the signal drops silently. It does not log any missed calls so there’s neither pressure to answer nor pressure to return calls.
Overall it works really well! It’s best if you're able to join with 4+ friends/family you’d like to chat with more. I have dozens of connections in the app now and it feels like absolute magic to me. I tap the button to send my beacon to everyone and get a random friend on the line.

It’s a one-to-many phone call that only one person can answer. Send a beacon to a group, and everyone gets pinged at the same time. The first person who answers gets connected for a 1-1 call, and for everyone else the signal drops silently. It does not log any missed calls so there’s neither pressure to answer nor pressure to return calls.

I've been working on a planner for the past 2 years for people whose day never goes the way they planned it.
I was trying to solve the problem I had with time-blocking, where your day ends up derailed and you give up on it because it takes too long to replan. I have solved with the idea of a cascading calendar. If I move a task down or change its duration it pushes other tasks later in the day.
Since then its kinda grown into my full productivity system for logging my thoughts and planning and documenting my life

I'm working on a simple way for AI's to talk to each other: https://counterparts.ai/phone
So far it's helpful for messages between my own AI's (chatgpt and claude etc), and for having my AI trade tech tips with a friend's AI or talk to my wife's AI. My AI also got its first message from a strangers AI from france which has also been really interesting. I read all messages first and approve before sending anything, but otherwise they're just talking about whatever they want.

I'm wrapping up my 2+ years of work on a browser-based version of EverQuest that plays itself: https://idlequest.net/
Also have some other cool browser-based 3d game projects listed here: https://brynnbateman.com/
I’m still working on https://leafle.org which is a tool for getting more interesting reading (or listening) suggestions that one can borrow from the library (or Libby). I’m done for the moment with building it, so I’ve been doing things like making flyers and leaving them in local libraries.
Guaranteed weight loss within 2–3 weeks; many people start seeing results within the very first week. 17,000+ members already!
Guaranteed results are achieved using the state of the art adaptive TDEE (total calorie burn of the day) tracking technique we've developed. It's sensorless, so no watch or other wearable is needed. It's way more accurate than those wearables (data included on the website), and our group has 2,000+ members ( https://macrocodex.app/community/ ). You can also read Play Store reviews.
All this completely free, no subscription or ads: https://macrocodex.app/
MacroCodex also works on both Android and iOS and any platform where PWA app can run.
Other other 2 apps are Android only (for now):
If you are looking for a workout app with Alpha Progression or MacroFactor Workout-like “Smart Progression,” or an app where you can run any program like Boostcamp but ad- and subscription-free, check out the Symbiote workout app (beta) https://symbiote-studio.macrocodex.app/
IF you are looking for AI photo Calorie tracking with lots of features which make it very fast to log food on daily basis checkout CalorieCodex (beta): https://caloriecodex.macrocodex.app/
All the apps have been under active development for a few months now.
Data driven, personalized typing application.
