Field Agent is one of the worst apps around LOL... you have started with the hardest app, so well done on making £25! Roamler requires an invite... you can get one here on TMS after you have 10 good posts, or browse the Roamler thread there is a few TMS users offering invites to give out, or, visit Roamlers facebook page where they give them out regularly. Roamler is the current top app.. there is always loads of tasks on it, some with poor pay to work ratio, others VERY good pay to work ratio... It is WELL worth joining... like all apps it is fluid...one day you can make £200 next day nothing... Roamler is known for raising the pay on tasks as it nears the end of the task (Can see pay rise from £3 to £12 overnight... trade off is do you risk holding off for more pay when there is a chance another user may nab it)Most tasks are fairly easy to do (no video). You should also join BeMyEye which is also a great app, it doesnt have a huge amount of tasks on, but, can see tasks at £7 raise up to £50 for same task. If you have an Iphone (or any Ios device) Task 360 has always (until lately) been the top app.. It is a bit quiet these days (hopefully just a lull) but tasks are mostly do-able and decent pay (most around £5) This weekend saw the latest round of "Blades" tasks which are checking on razor blades in big supermarkets... a VERY popular (but hard to do) task that pops up every few weeks, there is also a task to visit Vape shops and interview staff currently running with a sister task doing exactly the same but in Vape shops that are NOT on their map (ie: you walk past one, check the app... it may be on it or not) Also Manchester area has lots of tasks in that area. .. Streetspotr has many tasks in Burger King and MacDonalds and some other tasks... Streetbees gets the odd paid survey and some MS tasks, Clic & Walk again also gets the odd task, App Jobber has loads of tasks, but really poorly paid, but the odd one for £3 can be found.... Finally.. Market Force is a "traditional" Mystery Shop company that has an app version called "Eyes on" some good tasks in there too... good luck
