Long time lurker, first time poster.

Been juggling various note-taking, PKM, task management options for a while now and I've really honed in on some definite likes and dislikes.

Currently using bullet.to (free tier) and very happy with it, but really missing a place for "Daily Notes". Having Daily/Weekly/Monthly/Yearly views is great for pespective and preventing overwhelm (something I struggled with in other systems). Experimenting with gitlab.com/ferreum/pto as a mobile option for daily notes, but no web/desktop option. Drafting this post in Keep.

In the past I've used TickTick, manually creating Daily Notes in quarterly notebooks due to the 100 notes per notebook limit. Not as friction free as I wanted, but otherwise has a LOT of great features and I feel is often overlooked in PKM/Productivity discussions.

Before that was todo.txt with daily-notes in vscode and syncthing. Markor on mobile with the daily-notes.md in the quick note slot.

I initially styled my system based on plaintext-productivity.net. I still use that filesystem for my work files and projects.

Other tools I've looked at that fell short somewhere:
- workflowy
- remnote
- logseq
- amplenote
- obsidian
- super productivity
- checkvist
- joplin
- tana
- capacities
- nirvana/everdo
- there's probably others I've left out

Ideally I'm looking for a single solution that has:
- Android App
- Web Version (PWA)
- cloud sync
- either built-in to the app or 3rd party (e.g. Dropbox, Google Drive)
- I've done syncthing before, but I'd rather use a cloud option since I'd be using a work PC.
- Global Task List
- Capable of task attributes/notation along the lines of todo.txt.
- priority
- status ala GTD/orgmode also fun but not absolutely necessary
- context/list (@home, @work)
- project/tag (+proj1, +proj2)
- completion date (useful for monthly reports)
- creation date not as important
- threshold/start date
- due date okay if there's only one date assignable
- Task notes/description (a major gripe about todo.txt format)
- I regularly take notes on a task either as part of creation to provide addition detail or as I work on it that should be attached to the task and not somewhere else (e.g. daily notes).
- subtasks not necessary
- markdown format a plus with checkboxes
- Daily Notes / Working Memory
- a dedicated place to free write, daily
- outliner preferred over prose
- ability to manipulate nodes
- inline tags
- markdown support
- meeting notes and the like can also go here as a sub-heading.
- also helpful for monthly reports
- Natural Language Processing a plus
- Checkboxes distinct of Tasks
- Not interested in something that requires extensive customization/plugins/query-building to get what I want.
- Data export

I'm sorry for the awful single level list of bullets.
Looks like the indents didn't make it to the final post.

Check out NotePlan 3 ($99/yr) and Amplenote ($70–$120/yr). Both offer Mac, iOS, web, and Android apps (Amplenote also has a Windows app). Amplenote is cloud-first, whereas NotePlan is local-first and feels closer to a digital bullet journal. NotePlan stores notes as plain Markdown files, with work centered around daily notes. Sync can happen through NotePlan Sync or third-party services like Dropbox or Google Drive (though third-party sync might be being phased out). That approach tends to feel fast, especially if you value direct file access. But if your work PC does not permit access to personal cloud, Amplenote's web app seems more mature than Noteplan's.

Amplenote aims to aggregate tasks from across your notes into a single global view, where items can be sorted and surfaced based on factors like priority and due dates. NotePlan is designed to feel more like a digital paper planner in which you work primarily in daily notes and manually move tasks forward, which gives a strong sense of continuity but requires more hands-on, manual organization.

NotePlan stays close to plain Markdown plus has outlining features like collapsible bullet hierarchies. Amplenote renders Markdown into WYSIWYG-style, a la Typora.

If you enjoy explicit, text-based task systems like todo.txt, NotePlan is a natural choice since you’re directly working with structured text, and it replicates much of the feel of a bullet journal. If you prefer something closer to a traditional task manager Amplenote is better for managing projects/contexts/priorities & want the app to handle management and sync for you.

@satis...
No native Android app is a deal breaker, so no Note Plan. There's a bunch of Mac/iOS only apps I wish were cross-platform, but alas.

As for Amplenote I've tried it a handful of times and there are a few things that irk me. Below is a short (not all inclusive) list off the top of my head.
- If I want to take notes attached to a Task the only way to do that is their "rich footnote" feature, which is cumbersome especially in Mobile.
- No inline tags.
- Checkboxes are impossible.
I love the concept on paper, but the implementation of some key items is awful.

You put forward a very ambitious set of requirements and you may find it helpful to prioritize or trim requirements. Better, perhaps think in terms of using more than one app; most productivity tools aren’t designed to cover quite that wide or particular a range of needs. A lot of people on this site as well as most every productivity/app forum I've seen end up searching for a single tool to meet every need, but in practice most apps are better at a smaller set of functions. You may get closer to your needs with two apps than one.

Worth looking into:

Essential Pim (for Windows, but offers Android sync);
Upnote
Journal It! (has a very high learning curve, but after you overcome it you'll see what a terrific program this is)

Good luck! (and of course what Satis wrote above is spot on!)

Thanks for the replies so far!

@satis...
I'm aware it's ambitious. It feels like the Amplenote developers and I shared the same (or VERY similar) vision, but in practice it falls short.

@Leib
- epim not available for my version of Android (built for an older version).
- upnote... I'd rather just use Capacities as a note taking option.
- journalit!... Holy Overwhelm Batman! Friction free it is not.

I wrote Upnote, but I meant to write Upbase - worth taking a look...
