# Vimi vs Chalk

The clearest difference is review sentiment: Chalk at 100% against Vimi's 60%. Chalk also leads on ads (none vs shown) and rating (5.0 vs 4.6). Vimi's advantage is monetization model (free vs freemium) and ratings volume (914 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Vimi sells 7 in-app purchases, starting at $19.99 per month and Chalk sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Chalk holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Vimi has 914 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 60% of Vimi's written reviews are positive against 100% of Chalk's.

Vimi ships an update every 9 days, Chalk every 4 days. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
