Never had a problem at all with this wallet. Set up with a PIN and a fingerprint. That way if I fumblefinger the pin i can still access my funds. Unlike storage such as Breadwallet which locks you out for longer and longer each time it "says" your PIN is wrong then erases your wallet with all the money in it. This app is my go-to away from home. At least until Electrum publishes an IOS app...
