Power Pack users who purchased like you between 2014 and 2018 told us they'd pay us more money if we expanded the app to handle more programs than just Stronglifts 5x5. We did what they asked for, expanded the app to handle more programs incl Madcow 5x5, and those features are now part of Pro. If you're not interested, just keep using the features you purchased before, you have lifetime access to that. We've even given you a several extra features for free. We support you. Support us back.
