# Lumin vs Forma

The clearest difference is review sentiment: Forma at 69% against Lumin's 32%. Forma also leads on ratings volume (26K vs 916) and rating (4.7 vs 4.5). Lumin's advantage is in-app purchases (none vs 20) and update cadence (every 8 days vs monthly). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Forma sells 17 in-app purchases, starting at $3.99 per 7 days. Lumin asks for nothing beyond the download.

Forma holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Forma has 26K ratings behind it against 916, so its average is the more settled of the two. Written reviews point the same way: 32% of Lumin's written reviews are positive against 69% of Forma's.

Lumin ships an update every 8 days, Forma monthly. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
