Buy once instead of TickTick Premium
5 apps in the directory cover what people use TickTick Premium for. Each one is a one-time purchase.
TickTick Premium costs about $50 a year. At that rate TaskPaper, the cheapest dollar-priced replacement at $24.99, pays for itself in 6 months.
Read the catch on each one before you switch — a one-time price is not automatically the better deal, and we say so where it is not.
The replacements
TaskPaper
plain-text to-do lists in a real Mac app
$24.99 This version

The iPhone and iPad app is a separate purchase from the Mac one
2Do
configurable task manager, bought direct rather than from the App Store

Things 3
calm, opinionated to-do app you buy once per platform
$49.99 This version
Each platform is a separate purchase — the iPhone app is another $9.99
OmniFocus 4
heavyweight GTD task manager that still sells a perpetual licence
$74.99 This version
The next major version will be a paid upgrade, historically around half list price
