# HeadacheDiary vs PainGo

The clearest difference is rating: PainGo at 5.0 against HeadacheDiary's 1.8. PainGo also leads on update cadence (every 4 weeks vs every 7 months).

PainGo holds the better App Store score, 5.0 against 1.8. Both are backed by a comparable volume of ratings — 4 and 4 respectively.
