# Pulmonary vs Battery Brigade

The clearest difference is rating: Battery Brigade at 3.3 against Pulmonary's 2.3. Battery Brigade also leads on in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 4 months).

Both are free to download. Pulmonary sells 1 one-off in-app purchase. Battery Brigade asks for nothing beyond the download.

Battery Brigade holds the better App Store score, 3.3 against 2.3. Both are backed by a comparable volume of ratings — 3 and 8 respectively. Written reviews complicate that: 50% of Pulmonary's written reviews are positive against 29% of Battery Brigade's, so the app with the better star average is not the one people write more warmly about.
