I have an iPhone and use this app called Survey Mini which true to it's word it is mini. The shopping surveys are short in nature and take only a couple of minutes. Also, the points add up fairly quickly but the minimum amount to get any rewards is 4,000 points. But, a lot of everyday places I go to comes up with surveys on this app. Example is the bank I use popped up this last visit, Starbucks pops up sometimes, restaurants, etc. So sometimes it does not take much time to rack up points. I filled three surveys out this morning for three places I had been over the weekend and it took me approximately 5 minute which earned me 500 points. So for as far as time goes this one gets a thumbs up from me. I wish it took fewer points to get a reward.
My disappointment with this is so far is that I have not been able to use any of my rewards. First is the JcPenney rewards and their restrictions which is a huge list! I have looked at this list and not quite figured out exactly what I can use it on yet. I tried using one of these the other day but alas it would not let me. I had bought clothes for my grandsons and the clothes were on sale so I am thinking it cannot be used in conjunction with any sales. Also, once you say redeem the coupon you must use it or it goes away. So, that was one $10 coupon that I lost. Although the survey app is easy to use, I am not certain it is worth it if they all have a ton of restrictions like JcPenney but I have not used any others yet so I cannot say for certain if they do or not.
Currently, I am trying to save up for a reward to Firehouse Subs. I need 12,000 points for this one so this one will take me a while.
Keep watching as I will keep posting as I earn and use or try to use their rewards from this app.
