Huckleberry alternatives: which trackers predict sleep for free

This page is written by the people who make one of the apps on it. Pixy is ours, and you should read the rest knowing that — which is also why it reports what each publisher says about itself, links the page it came from, and ranks nothing.

Everything below was read on 8 September 2026 from the pages listed at the foot of the article.

Why people look for an alternative

Almost always the same reason: the feature they installed it for turned out to be paid. Huckleberry’s own feature comparison puts SweetSpot — the nap and bedtime prediction — under the Plus and Premium memberships, and its free membership under tracking, basic reports and multi-device sync. That is a pricing decision rather than a technical one. The prediction reads the wake times you have already logged and estimates the next sleep, which is arithmetic on your own data, and it is why so many apps can offer the same thing for nothing.

Worth saying before the table: Huckleberry sells more than prediction. Its Premium tier includes expert-designed sleep plans, which is a different product — a prediction tells you when, a plan tells you what to do about it.

Free prediction: who has it

Two things in that table are easy to skim past. Sofi charges for nothing — its site lists predictions, an Apple Watch app, caregiver sync, offline logging, WHO growth charts and data export as free, with no subscription anywhere. And Pippy does not claim prediction at all: it sells voice logging and shows wake windows, which is a different thing, and it is on this list because it is free rather than because it predicts.

Which one, and for whom

• Stay with Huckleberry if you want the sleep plan rather than the prediction. That is the part nothing here replaces, and it is what the Premium tier is really selling.
• Sofi if you want the most for nothing, and especially if getting your data out again matters. It is the only app here that lists export as a free feature.
• Napper if sleep is the whole reason you are tracking. It is built around the schedule rather than around general logging, which is the closest thing to Huckleberry’s shape.
• Pixy if you expect to still be using something after toddlerhood. It runs to twelve and changes what it shows by stage — feeds and nappies, then potty and routines, then homework and chores.
• Baby Tracker if you want the longest track record. It has been on the App Store for over a decade, which none of the others can say.
• Pippy if the thing you hate is typing. Logging by voice is its whole argument.

If you searched for “Huckberry”

You are in the right place — the app is spelled Huckleberry, and Huckberry is an unrelated outdoor clothing shop. Everything on this page is about the baby sleep app by Huckleberry Labs.

How to decide in one evening

Install two and log one real day in both. Not a feature comparison — an actual Tuesday, with the 4am feed logged one-handed in the dark. By the morning you will know which one you reached for without thinking, and that predicts whether you will still be using it in a month better than any table can.

If it helps to narrow the two, the full comparison goes through tiers and age ranges in more detail, and the criteria guide is about choosing without naming anyone at all.
