What Our Users Say
Don't just take our word for it. Here's what our users have to say about our Android app.
"I never said the reviews were all "1 star" you inferred that. I said they were "negative" which clearly they are. I also never complained about it not being "free." Obviously I'm fine with paying considering I paid for the app. My issue is that the app has problems and instead of addressing them you just make smart comments about how it's the user's fault. Considering the majority of reviews are bad I'd think you would listen to users and change it instead of acting like we can't use an app."

"garbage app. clunky, doesn't save your inputs(if it even takes your input) overall waste of $1"

"Works great,free trial is awesome but definitely worth buying all the upgrades. Once my friends and family relized how hand this is some purchased their own copy. Would give it 10 stars if possible."
Mike Risney
"Pretty good. Useful to be able figure out TAW and FOC based on options. It would be awful nice if you could, oh I don't know, minimize the app and be able to go to the internet and find your bows data(IBO speed, brace height, etc) and not have to completely start all over again and remember everything. Agree with other users, if you pay for an extra save you should be able to delete one and still have that available. Shouldn't have to switch everything up."

"Waste of money and time, garbage app"

"This app sucks.... hands down. Horrible to navigate, if you have to get out to add info, then get back in, you are stuck...."
Doctor Belleville
"Really? One save really is only one save and you have to pay again if you want to change one thing. Delete that save and you have to pay again. You suck. Just make the app 10$ instead of a bunch of little never ending purchases."

"Bait and switch app, anything useful is an additional charge. If you want access to the arrow database for example or to be able to save setups. Edit: Editing to reply to the developer's snide remarks. Your app is useless without premium features, which is fine if you publish it as a free demo version. If you're charging $1 for something then it should have SOME functionality of some kind."
JJ K
"App get stuck all the time. You have to pay 1$ for install which gives you nothing. Then pay 4.39$ for database so now you can do some calculations but it gets stuck all the time and you can't save your settings so reenter every time. Try to save your setting to auto load on crash pay more $$$ this app is stupid. Bad thing is I couldn't find alternative for this app so no competition for them"
