Prepare! — Start! — Release! — Repeat! — Switch! • ”I tried quite a few and this is the best one hands down!" • ”I might actually DO the exercises my PT prescribed, thanks to this app!" • ”I've looked at many timers for stretches, floor exercises, weight lifting... and this is the perfect one!" TIMER AND COUNTER FOR PHYSICAL THERAPY Keeps time, counts reps and sets, and lets you focus on your exercise, or something else—not the clock. YOU ENTER YOUR OWN EXERCISES Add instructions and photos, or a weblink, and set up your entire routine, exactly as prescribed by your therapist. Fine-tune cues and timers to match your personal pace. Note: this app does NOT offer pre-defined exercises (other than a few examples). KEY BENEFITS *** Some features are available only during the free trial or with a paid subscription as described below. • Stop counting seconds and reps—focus on proper form, breathing, or even reading or listening to music. • Clear voice and tone cues that work alongside music, podcasts, or when the app runs in the background. • Store all exercise instructions: notes, photos, and web links, with spoken guidance in a voice you choose. • Precisely adjust timers to fit your needs. • Schedule exercises and receive reminders. • Take notes after each exercise and email reports directly to your physical therapist. • Export workouts to PDF, including instructions, photos, and schedules. • Apple Health integration records exercise type and duration. MORE FROM THE REVIEWS • "The app is very easy to use and has resulted in the quality of my exercises increasing markedly … it does meet my needs to a "T"!" • "Best one ever. Have tried 2 others. At 65 stretching is important and this app helps." • "…it lets you focus on other things if you have simple boring exercises." BASIC VERSUS PAID SUBSCRIPTION CAPABILITIES Without a subscription, PT Timer provides limited basic functionality. During a free trial or an active subscription, you can create new exercises with instructions, timers, schedules and more. After the free trial, without a subscription, functionality for those exercises becomes limited. • In basic (unpaid) mode you can: view exercise routines created during a trial or subscription; view instructions and photos; receive already scheduled alerts; check off completed exercises; add and view notes after completing exercises; export to PDF. • Subscription-only features include: timing and counting; creating and editing exercises and workouts; modifying schedules; technical support. • NOTE: This app does not provide exercises or instructions (other than a few examples). You must enter exercises tailored to your own needs. TERMS OF SUBSCRIPTIONS Several subscription options are available with different renewal periods. They all provide access to the full functionality of the app. The prices of subscriptions vary by country and are shown within the app. Payment will be charged to the Apple Account at confirmation of purchase. A subscription automatically renews unless the subscription is cancelled at least 24-hours before the end of the current period. The Apple Account will be charged within 24-hours prior to the end of the current period at the price specified for current subscription. Subscriptions may be managed by the user and cancelled by going to the user's Account Settings after purchase. Any unused portion of a free trial period will be forfeited when the user purchases a subscription.

Verdict

The call

The clearest difference is ads: PT Timer at none against Interval Timer's shown. PT Timer also leads on review sentiment (81% vs 69%). Interval Timer's advantage is ratings volume (19K vs 95) and update cadence (every 9 days vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and PT Timer sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Interval Timer holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 95, so its average is the more settled of the two. Written reviews complicate that: 69% of Interval Timer's written reviews are positive against 81% of PT Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Interval Timer ships an update every 9 days, PT Timer every 5 weeks. The most recent releases landed on September 25, 2026 and August 11, 2026 respectively.
