Super easy, super flexible, and dead simple. Full print, export, import. Can’t say enough good about it. ### 5/5 — Absolut top! Kenne keine Bessere! Perfekt durchdacht! *2026-06-02, version 3.19.3* Die App besticht durch Eleganz und absolut anwenderfreundliche Benutzerführung. Jede Funktion ist durchdacht – alles läuft fließend. Ich nutze diese App seit vielen Jahren - die wurde immer besser. Ich habe Listen für meine Dienstreisen, für meine Privat Urlaube, für meine Weihnachtsgeschenke, Für Vokabeln lernen, für To-dos auf Reisen und und und ... Alles kann man super kategorisieren und auch vorab abhaken. Im Sommer auf Reisen zB. kann ich mit einem Klick alle Wintersachen deaktivieren. Danke an die Entwickler, die diese App seit vielen Jahren immer wieder aktualisieren. Ich vermisse nichts! ### 5/5 — Astonishingly Great *2026-05-10, version 3.19.3* This is software the way it should be. It does one job, it does it VERY well, VERY fast, and with perfect reliability. I have the OmniOutliner v5 but I use this instead on the iPhone. This is not trying to do a million other things, it just does outlining to perfection, so it’s faster, simpler, better. I appreciate the fact that this uses standards based files so swapping between OmniOutliner and this via DropBox works perfectly. I use it all day every day. My daily routines are in here, as are my weekly and monthly routines - check things off then reset for tomorrow / next week / next month. I also have a tonne of checklists in here - such as standard lists of things I might need when I visit various stores, things to do when visiting other cities, packing lists for travel, favourite stopping points on long trips, and on and on. I’ve been using it for more than 10 years and unlike so many packages it’s never lost its way, never made silly changes to try and bring in whole new classes of user, and so on. …and today I found out that there’s a free online companion that lets me access my CarbonFin account from the web. Awesome! If the developer wants to get a Patreon or something going I’d be very happy to donate to keep this great bit of software going. ### 5/5 — Parfait *2026-02-03, version 3.19.2* Parfait, simple et efficace. ### 5/5 — very good !! 너무 좋네요 *2025-12-13, version 3.19.2* It's so nice Please stay updated for a long time I think it would be nice if you could change the font I love it. Please take care of the app constantly. 👍👍👍❤️ 깔끔하다....😌 ### 3/5 — Unexpected Error: 500 *2025-11-28, version 3.19.1* I love, love, love this app, and have been using it for many years, but for the past year or so I’ve noticed that when I try to save the data in the app, it gives me an “unexpected error: 500” pop-up, and I can see that half of my text files are being left unsaved. This makes me nervous that my data is vulnerable to being lost forever, which explains the 3 star rating. Fix this, and I’ll set it back to five stars! :-) ### 2/5 — Big problem *2025-11-24, version 3.19.1* I’ve used the previous version on my ipad and have been very happy with it. The new version however has me reconsidering my fidelity to it. The pane that lists my outlines will not go away, shrink, or move out of the way, thereby eating up a third of the screen. The keyboard is now much bigger and now fills a third of the screen from the bottom. What’s left is a postage stamp sized space for the outline itself. This is unacceptable. Am I doing something wrong? ### 1/5 — Latest version loses functionality *2025-10-19, version 3.19.0* The new drop down menu basically is confusing and not as easy as the bottom Page menu bar was. ### 5/5 — Excellente app de gestion de tâches *2025-10-18, version 3.19.0* Excellente app de gestion de tâches, très ergonomique. Un plus très utile est la synchronisation entre iPhone, iPad et interface Web ### 5/5 — Fast, simple, EASY *2025-10-13, version 3.18.0* I’ve been using this thing for Years. A no frills outliner that does everything you need. Unbelievably easy, fast, intuitive, STABLE. Don’t get wrapped up in options- use this and GET THINGS DONE. ## Frequently asked questions about Outliner ### What does Outliner do?
