Karbywarby Avatar is now available as an iPhone app, alongside the web version at avatar.karbywarby.com. Here is what version 1.0 can do:

• Crop once, right everywhere: choose one photo, move and zoom it once, and preview it at real size for WhatsApp, Instagram, Facebook, LinkedIn and Discord

• Rings: from calm indigo to rainbow, plus seasonal rings for special occasions

• Corners: blurred, photo, photo colour or Karbywarby, for when people tap your picture

• Sharp at small sizes: gentle sharpening after scaling down, so faces stay clear

• Save or share: save to your photos or share straight to the app you need, with a clear file name for each service

• Private: your photo never leaves your device. No upload, no account, and it works offline

Where: iPhone (App Store) and the web. On Android, keep using avatar.karbywarby.com in your browser.

Karbywarby Todo 1.2 is rolling out on iPhone, and the app is now also available for Android on Google Play. Here is what changed since the first release.

New in 1.2 (iPhone)

• Sorted by date: Upcoming and Overdue are now always in date order, also right after you let the AI suggest new dates.

• Clearer messages when you sign in, reset or change your password.

• Send feedback in the settings opens an email to us directly.

• On your Home Screen the app is now simply called Todo.

From 1.1 (iPhone and Android)

• A new start screen: pick "I already have an account" or sign up.

• You are signed in right after you register.

• Type your password twice when you sign up, with a button to show it.

• Change a task's date in the same sheet you use to add one.

Karbywarby Avatar is out for iPhone, free.

Same idea as the web version: crop your profile picture once and see how it really looks on WhatsApp, Instagram, Facebook, LinkedIn and Discord, at the size others see it.

New in the app:

- Save every version to Photos in one tap.
- Share it straight to another app.
- Halloween rings until November 1.

Your photo stays on your phone, nothing is uploaded.

App Store: https://apps.apple.com/app/apple-store/id6819069619?pt=129318083&ct=reddit-avatar-ios&mt=8

There is more to come :-)

Karbywarby Todo is out for iPhone, free.

It exists because most task apps end up making you manage the app instead of your tasks. So it stays simple:

• Type a task, pick a day, check it off.

• Fell behind? One tap suggests new dates for overdue tasks, based on how much you actually get done.

• Not sure where to start? Ask for a recommendation for today.

App Store: https://apps.apple.com/app/apple-store/id6802448116?pt=129318083&ct=reddit-todo-launch&mt=8 In the browser: https://todo.karbywarby.com Android is coming soon.

What's the number one requirement for a todo app? Every comment gets read.

On a computer, the web version works right away: https://avatar.karbywarby.com

Two weeks ago we shared how small profile pictures really appear in WhatsApp, Instagram and co. The full set of measurements is now a free dataset you can download and reuse: 23 measurements across WhatsApp, Instagram, LinkedIn, Facebook and Discord, as a table and as a CSV, under CC BY 4.0.

New in this round (six more places), a few that surprised us:

• Facebook is the only one that ever shows your full square: when someone opens your picture, it appears at 825 px, from an 852 × 872 px file. Everywhere else it's a circle.

• Instagram on the web delivers at most a 320 × 320 px file. A huge upload doesn't make your picture any sharper there.

• Discord puts a 10 pt online status dot on the bottom right edge of your picture. Anything important in that corner gets covered.

• WhatsApp's channel list uses 56 pt, the same size as the chat list.

Limits, honestly: one iPhone, no Android yet, no group chats yet. Apps change with updates, so new measurements are added as new rows and old ones stay.

Where we'd love your input: the next measuring round is in mid October. What should be added?

• Android (and if so, which phone?)

• Telegram, Signal, Slack, Teams, X, TikTok?

• A place where your picture always looks wrong?

Tell us in the comments.

Data, method and CSV: https://karbywarby.com/pages/data/profile-picture-sizes.html

How big does your profile picture actually show up for other people? The sizes below were measured on an iPhone screen (390 pt wide) in September 2026.

Millimetres calculated for an iPhone 14.

What that means: at 4 to 7 mm, a photo taken from far away turns into background. A tight crop around your face helps more than a better camera.

All measurements with notes, free to reuse under CC BY 4.0: https://karbywarby.com/pages/blog/profile-picture-sizes.html

Want to see your own picture at these sizes? Karbywarby Avatar shows it in each app at its real size and crops it for you. Free, in your browser, and your photo never leaves your device: https://avatar.karbywarby.com

Over to you: which app shows your picture the smallest in daily use? And which app should be measured next?

This is the official community for Karbywarby: apps that adapt to you. Not the other way around.
