Verdict

The call

The clearest difference is rating: LiquidText at 4.6 against Dev Calc's 2.0. LiquidText also leads on ads (none vs shown) and ratings volume (6.4K vs 2). Dev Calc's advantage is review sentiment (60% vs 50%) and iOS requirement (13.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

LiquidText holds the better App Store score, 4.6 against 2.0. That said, the two scores are not equally well evidenced: LiquidText has 6.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of LiquidText's written reviews are positive against 60% of Dev Calc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

LiquidText ships an update every 2 weeks, Dev Calc every 2 months. The most recent releases landed on September 23, 2026 and June 4, 2026 respectively.
