Welcome to Episode #95 on the long and winding road to find the best Android note-taking app. Before getting to this week's app, a note of thanks.

Welcome Shishir from India and thanks Jonathan from Germany for the paid subscription! I'm happy and thankful to have you both along for the ride!

I mentioned briefly last week that I got a new phone, upgraded from the Samsung S20 5G which I got at the beginning of COVID-19 and loved because it was lightweight and fast. The new one is the Samsung S23 Ultra and OMG it's an incredible device. The main reason for getting this specific phone was to get the S-Pen support so I don't have to buy a tablet.

A good friend explained how it has one of the most secure chips on Android phones, the Snapdragon 8 Gen 2. It forces a restart of the device if an app tries to write in another's memory space. I believe it's part of their "Trusted Execution Environment (TEE)". Pretty cool.

I now remember how much I used to love writing notes on my Samsung S-Series tablets so if you see me review some "written" note apps in the future, that's why. For now, I'm using Samsung Notes for drawing which was one of the best Android note-taking apps when I reviewed it back in Oct 2021. A great side benefit for me is that this device loads Obsidian much faster.

Ok, onto this week's app.

This week I reviewed ImapNotes3 which is another app suggestion from Asen in Bulgaria. Thanks, Asen!

ImapNotes3 requires a little extra work to get going but once set up, it's very easy to use. To get the app you need to use F-Droid which is a platform similar to Google Play, not run by Google, and provides Free and Open Source Software (FOSS) apps

The app integrates your notes into Fastmail, Gmail, Yahoo, iCloud, and Posteo so you don't need to subscribe to a notes service! Notes are stored as HTML emails, a very smart idea.

With Fastmail the notes show up under Notes the menu and in Gmail they show up as labelled notes which makes sense and works well. I use Fastmail and am going to be keeping this app on my device.

It could be great as a companion to your email service although it doesn't support attaching images you can embed a link (URL) to the image if it exists somewhere.

ImapNotes3 is free, fast, has no ads, and supports WYSIWYG editing including tables and checklists, exporting to HTML, collapsable sections, tags, and 19 font colours.

Read on for the ugly, the bad, the good, the great, and the awesome aspects of ImapNotes3.
