Verdict
The clearest difference is monetization model: Lite Invoice at free against Cantus Pro's subscription. Lite Invoice also leads on ratings volume (12 vs 1). Cantus Pro's advantage is update cadence (every 3 days vs fortnightly) and rating (5.0 vs 4.8). 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.
Cantus Pro holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Lite Invoice has 12 ratings behind it against 1, so its average is the more settled of the two.
Lite Invoice ships an update fortnightly, Cantus Pro every 3 days. The most recent releases landed on October 5, 2026 and October 9, 2026 respectively.
