# Tsubook vs I.M.T.C.

The clearest difference is in-app purchases: I.M.T.C. at none against Tsubook's 10. Tsubook's advantage is update cadence (monthly vs every 30 months) and device support. On price there is nothing between them.

Both are free to download. Tsubook sells 10 in-app purchases, starting at $1.99 per month. I.M.T.C. asks for nothing beyond the download.

Tsubook ships an update monthly, I.M.T.C. every 30 months. The most recent releases landed on October 13, 2026 and October 1, 2026 respectively.
