Too many adverts

I would love to trial this app before purchasing but there’s an advert after the first diary entry and if I try and add something else then there’s another advert. Which I’m forced to watch all the way through. I’d love to see this app working but can’t because of adverts. If I do decide to buy it then will all the adverts vanish. Very little information on what you get if purchased. I’m sure I can give a 5 star review but need to try before I buy but I can’t due to far too many adverts.

Please fix this

Every time I try to start a new entry it gives me and ad. Which I know is supposed to happen but even when I watch the ad and try again it gives me another over and over again. It’s really annoying
Seriously??!?!!Seriously??!?!!
