# Invoy vs Well Digital

The clearest difference is monetization model: Invoy at free against Well Digital's free with in-app purchases. Invoy also leads on review sentiment (89% vs 80%) and iOS requirement (13.0 vs 17.0). Well Digital's advantage is ratings volume (28K vs 76) and rating (4.9 vs 4.6). On price, ads, in-app purchases and device support there is nothing between them.

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

Well Digital holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Well Digital has 28K ratings behind it against 76, so its average is the more settled of the two. Written reviews complicate that: 89% of Invoy's written reviews are positive against 80% of Well Digital's, so the app with the better star average is not the one people write more warmly about.

Invoy ships an update every 6 weeks, Well Digital fortnightly. The most recent releases landed on October 23, 2026 and October 28, 2026 respectively.
