DO NOT buy the pro version and DO NOT buy any boost. DO NOT buy their subscription. I regretfully bought the useless pro version for £2.19 and on top I paid £60.99 for a 15x boost and it just vanished in thin air. They took money out of my account and there was no boost whatsoever. I was still on 1x. Contacted the support and was sent email that we are looking into it. Asked for a full refund and sent them invoice as proof and after that it's complete silence, no response from them. That's £60.99 stolen from me. Rubbish app, appalling support, unethical business practice and just cons/ thiefs to steal your money. Complaining to consumer ombudsman and will take it further till I get my money back. On here, a bot will respond to your review (see rest of reviews) which doesn't help at all. Stay away from this app. There are plenty others much much better than this utter rubbish.
