$15 to $30

The $15 licence stops getting updates after two years; only the $25 tier is a true lifetime

Major versions are a paid upgrade — Moom 3 to 4 cost owners $8 — and free updates run about a year

Useless without a trackpad; on a mouse-only Mac almost none of the gestures are reachable

None found

Updates stop when your one- or two-year window ends; the version you have keeps running

The $19.99 covers the 1.x series only; a future 2.0 would be a separate purchase

Buy it on the Mac App Store — the developer's own site sells a separate web version

Which sites work depends on constant updates; a redesign can break one for a while

Compression only: no editing, OCR or signing, and a future major version may be paid

The iPhone and iPad app is a separate purchase from the Mac unlock

One licence covers two Macs at a time, so a third means deactivating one

A future Scapple 2 would be a separate purchase, as with Scrivener

One purchase covers about a year of updates, after which newer major versions are a fresh buy

Company or institution machines need the $15-per-computer site licence, minimum five

Whether hardware brightness control works at all depends on your monitor, cable and dock

No iPhone or iPad app — on mobile you edit the file in someone else's text editor

$24.99 buys Bartender 7 only; version 8 is a paid upgrade and Pro features are yearly

Updates stop after a year unless you renew at 40% off; your copy keeps working

Each major version is a fresh $29.99 purchase, not a discounted upgrade

The iPhone and iPad app is a separate purchase with its own monthly subscription

The $29.99 tier is the discounted pack; the two full unlocks are $49.99

The nodes worth having are Pro-only, which is $49.99 rather than the $29.99 standard edition

One year of updates included; another year costs 60% of what you first paid
