Clean interface but a disaster to use – Good Todo Review

I actually liked the clean interface enough to upgrade to a paid user ... Oops! I'm not sure as to how or why, but it seems like whenever I'm out of wifi range with my ipad, it starts to happen -- triple, quadruple, or even higher multiples of repeat entries when the ipad is able to re-"sync". I'll have maybe 30 todo's then suddenly 120 appear and I've got to go through and try deleting those that are repeats without accidentally deleting valid ones. Nightmarish. Tried contacting support twice, to no avail.
