Very little customization

This is possibly the worst breathhold app out there, with essentially no ability to build your own or customize the basic tables. Many other features missing from a serious freedive training standpoint

Remove ads not working

I love the app but sadly removing ads is not quite working. I paid for the feature but the ads keep reappearing randomly, so I have to constantly use “restore premium” menu to turn them off again. Could you possibly fix it?
UPD: the developer did not respond, but rebooting the device and restarting the app a few times has somehow cleared the issue.
