# Calculator´ vs TimeGPT

The clearest difference is rating: Calculator´ at 4.6 against TimeGPT's 2.5. Calculator´ also leads on ratings volume (478 vs 12). TimeGPT's advantage is in-app purchases (none vs 4) and update cadence (weekly vs every 5 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Calculator´ sells 4 in-app purchases, starting at $0.49 per year. TimeGPT asks for nothing beyond the download.

Calculator´ holds the better App Store score, 4.6 against 2.5. That said, the two scores are not equally well evidenced: Calculator´ has 478 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 70% of Calculator´'s written reviews are positive against 67% of TimeGPT's.

Calculator´ ships an update every 5 weeks, TimeGPT weekly. Both last shipped on October 24, 2026.
