Avoid Pro Version unless you like advertising
Ok, so you pay to get the Pro Version, but then get numerous nags each day to get their other apps! What was I paying for? Do you own your data? App links to free account that it nags you to create EVERY time you open the app (again, why did I pay?) but you can only truly see your data if you now pay for a premium account there. SCAM to once again push you into a paid subscription. PRO version? Yeah right. Skip this one.
