Hi, I'mIsaac.I build apps I actually use.

Everything here started as something I wanted to use. I design it, build it and ship it on my own, then live with it every day. I mostly build for myself, but I'm open to working with others when it feels right.

01 / Work

Things I've shipped.

Each one fixed a problem I had. They're in real stores, with real people using them.

Repify

Every rep, counted.

Live

Tracks every set, tells you what to lift next, and turns raw effort into progress you can actually see, workout after workout.

Why I built itI wanted a tracker that told me what to lift, not a spreadsheet with a logo on it.

CanvasMCP

Give your agent a canvas.

Live

A macOS design app your AI can actually use. Ask Claude or ChatGPT. Real frames appear on the canvas. You tweak, export, ship. The file stays on your disk.

Why I built itI wanted Claude to draw real frames on my Mac, without my files leaving my disk.

02 / About

Just me, start to finish.

I'm Isaac. IJR APPS is one person: no team, no agency, no client queue. Every app here exists because I wanted it, and I kept going until it was good enough to put my name on.

How I workOn repeat
  1. Design

    Sketch until the screen is obvious.

  2. Build

    Native code, tuned until it feels instant.

  3. Ship

    Real releases, with my name on them.

  4. Use

    Live with it daily. That picks what's next.

Working togetherSometimes

I make my own stuff. But if you like what's here and have something you'd like me to work on, send a message.

Feels right when

  • You like what I've already made
  • Small team, quick decisions
  • It ends up a real thing people use

Probably not

  • Anything I wouldn't be proud to ship
  • Agency-style retainers
  • A spec that's already locked

Got one in mind?

Repify

If you're serious, download this

by Harjan B
I'm being honest, if you are serious about losing weight or gaining muscle you have to download this app. All the other ones don't make it as simple as this. In 3 months I dropped 20kg using the 4 day split and tracking my calories with the ai calorie tracker.
Repify

It literally tells you what to lift

by Hdldmfkflekdnd
I thought I'd give it a go, why not? It literally tells you what to lift, it holds you accountable for what you were lifting last week. Now every gym session I'm getting stronger and progressing faster. Hit a PR on my bench press after using this for a month.

I feel young again

by Sid.Patel
I've never been the type to track workouts or calories, but WOW it really does help you progress. I used the 4 day split and it got me progressing faster than I have in years. I feel young again especially as an older gym goer. If you're looking to reach a fitness target this app is a MUST.
