# Brain Collector vs Ink Sync

The clearest difference is update cadence: Ink Sync at every 4 days against Brain Collector's monthly. Ink Sync also leads on device support. Brain Collector's advantage is monetization model (free vs free with in-app purchases). On price, review sentiment, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Brain Collector sells 1 one-off in-app purchase and Ink Sync sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Brain Collector ships an update monthly, Ink Sync every 4 days. The most recent releases landed on October 10, 2026 and October 24, 2026 respectively.
