Inkstone holds a fond place for a lot of Chinese learners: a free, open-source character-writing app that did the core job without asking for money. Then time caught up with it. As an abandoned project, it stopped working when modern iOS required 64-bit, leaving users searching for an equivalent. If that is you, here is how to replace what actually mattered about it.
What Inkstone was
Inkstone was a free, open-source app associated with the Skritter team, offering character-writing practice without a subscription. Its appeal was a combination of focus and fairness: it concentrated on writing characters and it was free and open. For many learners it was the no-cost way to drill handwriting.
Its weakness, in the end, was maintenance. An unmaintained app falls behind platform changes, and the shift to 64-bit-only iOS broke it. That is the recurring fate of abandoned software, and the reason “Inkstone 64-bit update” is a search that leads nowhere good.
What to protect in a replacement
When replacing a beloved tool, the danger is grabbing whatever looks similar and quietly losing what made it good. For Inkstone, protect:
- The writing focus. It was about producing characters, not broad vocabulary. Keep a tool centered on from-memory writing, see the case for a dedicated Hanzi writing app, not one that drops to recognition or tracing.
- Stroke feedback. So you build correct habits.
- Fair access. Inkstone was free; you do not have to accept predatory monetization to replace it, see a character tool without predatory monetization and a Chinese writing app with no subscription.
If open-source itself was the draw, note that the scheduling algorithm is the commodity part and is available openly, even if a given app is not, see open-source spaced repetition for writing Hanzi.
The maintenance lesson
There is a quiet lesson in Inkstone’s fate: a tool is only as good as its upkeep. A maintained app that keeps pace with the platform is worth more over time than a brilliant abandoned one. So when choosing a replacement, an actively developed tool matters, even if it is newer.
Where Hanzi Write Practice fits, honestly
Hanzi Write Practice shares Inkstone’s core focus, writing characters from memory, and is free during early access, with a planned honest pricing model rather than predatory mechanics. The honest differences: it is not open-source, and it is not a clone of Inkstone’s exact feature set. It is a modern, actively developed, focused take on the same job, drawing each character from memory on a grid with stroke feedback and spaced repetition.
If what you miss about Inkstone is free, focused writing practice that actually keeps working, that is the lane we aim for.
Join early access and get focused writing practice that stays maintained.
