# Spectrum vs On Time

The clearest difference is review sentiment: Spectrum at 90% against On Time's 50%. Spectrum also leads on ads (none vs shown) and rating (4.7 vs 4.5). On Time's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 2 days vs every 5 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Spectrum sells 2 in-app purchases, starting at $9.99 per 7 days and On Time sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Spectrum holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Spectrum has 274 ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 90% of Spectrum's written reviews are positive against 50% of On Time's.

Spectrum ships an update every 5 days, On Time every 2 days. The most recent releases landed on September 23, 2026 and September 18, 2026 respectively.
