The best fitness tracker 2026 offers under $100 is a surprisingly capable device, and there are several good choices according to how you like to wear it. The Fitbit Inspire 3 is named best overall under $100, with around 10 days of battery life and cycle tracking, though some of its best features need a Fitbit Premium subscription. The Samsung Galaxy Fit3 is another budget favourite, praised for its large screen, long battery life and low price, which makes numbers easy to read at a glance. If you do not want a display, the Google Fitbit Air, released on May 26 at $99.99, sits right at the edge of this budget. It is a screenless band that weighs only 12 grams, and it tracks fitness and sleep quietly in the background. The Amazfit Helio Strap is another screenless option, praised as a subscription-free rival to the WHOOP band, which matters if you want to avoid monthly fees. Price is only part of the cost, so check a few things before you buy. Check if the app withholds useful insights behind a monthly subscription, because a bargain tracker with a paid plan will end up costing more over a year than a more expensive fitness tracker without one. Look at battery life; a band that lasts a week or more is easier to wear than one that doesn't and be sure to get one that can cope with a swim or shower if you want to wear it there. Built-in GPS isn't common at this budget level, so most cheap fitness trackers will need your phone to track your route. Don't expect amazing heart-rate and sleep figures, treat them as trend indicators rather than hard facts, and check how much you're paying after discounts, as there are often deals on. The comfort level will determine how useful any fitness tracker is, because one you wear constantly will gather far more complete data. Smart buyers want to read from people who've tested products first, and TechyAssist can help with that by giving expert reviews on the best fitness tracker 2026 has for you.
