I've been using Optimity for a few months now and I love how easy it is to use. Just walk 6000 steps every day to get the rewards in points. There’s also questionnaires you can answer to get more. Personally I find the questionnaire rewards too small to bother with and I just want passive income. I’ve already claimed my points for petro-points (Petro Canada) a few times and I got them credited to my petro-point card two days after the claims. Points can also be claimed for gift card raffles or coupons. The app is available in Canada and works on both iOS and Android.
