# Mobius vs INKBIRD

The clearest difference is rating: INKBIRD at 3.7 against Mobius's 2.0. INKBIRD also leads on update cadence (fortnightly vs every 2 months) and ratings volume (6.8K vs 328). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

INKBIRD holds the better App Store score, 3.7 against 2.0. That said, the two scores are not equally well evidenced: INKBIRD has 6.8K ratings behind it against 328, so its average is the more settled of the two. Written reviews complicate that: 27% of Mobius's written reviews are positive against 23% of INKBIRD's, so the app with the better star average is not the one people write more warmly about.

Mobius ships an update every 2 months, INKBIRD fortnightly. The most recent releases landed on September 21, 2026 and September 24, 2026 respectively.
