# Injectly vs OnePin

The clearest difference is in-app purchases: Injectly at none against OnePin's 1. Injectly also leads on ratings volume (501 vs 7). OnePin's advantage is update cadence (every 5 days vs every 2 weeks) and review sentiment (100% vs 87%). On price, rating, ads and device support there is nothing between them.

Both are free to download. OnePin sells 1 in-app purchase, starting at $49.99 per year. Injectly asks for nothing beyond the download.
